Three-Phase Imbalance Control
Function Introduction
Three-phase imbalance control is used when three-phase loads are unevenly distributed. According to set single-phase current or power limits, it adjusts the energy storage PCS per phase to keep the three-phase current or power at the grid gateway (service entrance) balanced and within limits as much as possible, ensuring stable system operation. This function can only operate during charging or discharging (not both).
After enabling three-phase imbalance control, the system will perform per-phase adjustments to PCS based on real-time operation without affecting normal power use and production.
Function effects:
Real-time monitoring of three-phase current and power status;
Control according to set single-phase current or power limits to relieve single-phase overload issues;
This function helps customers solve the following problems:
Reduce the risk of single-phase overloads and anomalies;
Improve three-phase imbalance and ensure power safety;
System automatically adjusts without manual intervention;
Note: Displayed contents on the three-phase imbalance page vary by device model. This field explanation summarizes all fields across different versions of the three-phase imbalance page.

Transformer Protection
Function Introduction
Transformer protection is used at sites with large load fluctuations or multiple power sources (such as storage and PV). It automatically adjusts storage charge/discharge power to prevent power at the grid gateway (service entrance) from exceeding transformer capacity, reducing transformer overload risk. After enabling transformer protection, the system will automatically adjust storage charge/discharge power based on real-time operation without affecting normal use and production. This function can also be used in scenarios without a transformer at the grid gateway but with a power throughput limit requirement.
Function effects:
1. When load suddenly increases, automatically reduce storage charging power or switch to discharging to alleviate transformer stress;
2. When storage is discharging at high power and other sources are present, automatically limit storage discharge power;
3. Ensure power at the grid gateway (service entrance) stays below the transformer’s safe capacity;
This function helps customers solve the following problems:
Reduce transformer overload and trip risk;
Ensure stable station operation;
System automatically adjusts without manual intervention;

Demand Control
Function Introduction
During electricity usage, the grid charges based on the "maximum electric power (demand)". If power at any moment suddenly exceeds the maximum demand, it may cause a significant increase in the monthly electric bill.
The demand control function helps you automatically manage power peaks and avoid exceeding maximum demand. The system monitors the power at the station-grid connection (gateway/service entrance) meter in real time like a "power monitor", 24/7.
When the system detects that current power approaches or exceeds your preset "Maximum Allowable Demand", the system will automatically take measures:
Prioritize using storage battery discharge to reduce grid power draw;
Increase PV output where possible to use more self-generated power;
These methods keep power at the grid gateway (service entrance) within the set range to avoid additional demand charges caused by instantaneous high power.
Function effects:
No frequent manual parameter adjustments required;
The system automatically adapts the control limit based on actual power usage;
Continuously optimizes energy costs while ensuring normal production;
This function helps customers solve the following problems:
Prevents sudden power spikes and costly demand overages;
Makes fuller use of storage and PV to reduce purchased electricity;
This function can also achieve peak shaving effects;
Fully automatic control without manual monitoring;

Actual Demand (kW)
--
--
In some enterprises real-time demand settlement is used. After enabling demand tracking, the system automatically reads the "historical maximum demand" from the gateway meter and uses it as the current control reference.
Anti-feed-in
Function Introduction
If PV generation plus storage discharge exceeds on-site load demand, excess power will flow back to the grid (feed-in). If feed-in power exceeds local limits, this may result in grid compliance violations, fines or uncertain revenues. The anti-feed-in function helps automatically prevent this.
The system monitors power at the station-grid connection (gateway/service entrance) to determine if there is a tendency to feed power back to the grid. When it detects PV generation + storage discharge > on-site load (i.e., imminent or occurring feed-in), the system will automatically adjust based on feed-in settings: reduce storage discharge power or switch storage to charging, and if necessary limit PV power.
Function effects:
Automatically prevent excess power from being sent to the grid to meet local grid requirements and avoid penalties or compliance risk from over-feed-in;
By these adjustments, the station's generation will just meet site demand without sending surplus to the grid;
This function helps customers solve the following problems:
Prevent reverse feeding to the grid and avoid penalties or operational risks from feed-in;
Setting a positive maximum feed-in power can enable valley-filling effects;
Fully automatic control without manual monitoring;
Page field business explanations:

Maximum Feed-in Power (kW)
Value range: -99999.9~99999.9
One decimal place
Enter a positive value (common in "0 feed-in" scenarios): if on-site requirements forbid feeding to the grid, set the maximum feed-in power to a positive value. EMS will control power bought from the grid to equal this set value to avoid short-term feed-in caused by sudden load drop.
Enter a negative value (used when feed-in is allowed): if on-site feed-in is allowed, set maximum feed-in power as a negative value. EMS will control feed-in to the grid not to exceed the set absolute value.
Maximum Feed-in Power Coefficient (%)
Value range: 0~100
Integer
Maximum feed-in power = PV installed power * this coefficient. When measured feed-in at the gateway exceeds the maximum feed-in power, the system automatically starts anti-feed-in control to prevent over-feed-in.
Reserved Backup Power
Function Introduction
In scenarios with possible power outages, you can reserve part of the battery energy as emergency backup for devices on the backup port. During normal operation and discharge, the system will ensure battery energy never falls below the configured "UPS Reserve SOC" to avoid using up the emergency power. When the system detects battery SOC below the reserved backup SOC, it will automatically start recharging to top up the battery. Recharge power will follow the configured backup power on the page to ensure safety without affecting other power needs.
Function effects:
Reserve emergency energy in the battery in advance to ensure important loads connected to the backup port remain powered during an outage;
The system automatically limits discharge during normal operation so battery SOC does not fall below the reserved backup value, and automatically recharges when needed;
This function helps customers solve the following problems:
Ensure power availability during outages to keep devices on the backup port running;
Fully automatic control without manual monitoring;
Page field business explanations:
UPS Reserve SOC (%)
Value range: 0-100

Devices will charge the battery using this power setting.
Power Factor Control
Function Introduction
Used to automatically adjust the station's reactive power output to help maintain a reasonable power factor, reducing penalties for poor power factor. Suitable for sites with large load fluctuations and risk of power factor adjustment fines. Once enabled, the system will automatically adjust reactive power based on station operation without affecting normal use and production.
Function effects:
Real-time monitoring of the station power factor;
Automatic reactive compensation adjustments;
Keep the power factor stable within acceptable range;
Reduce or avoid penalties for power factor adjustments;
This function helps customers solve the following problems:
More stable electricity cost structure when power factor is compliant;

Used to set the desired power factor at the grid connection point. The system will automatically adjust storage reactive power to approach this target. Values closer to 1 indicate less reactive power and more reasonable consumption, better meeting grid requirements.
Auxiliary Control
SOC Calibration
Function Introduction
SOC calibration is a controlled charging process that lets the system re-confirm the battery's actual energy so that displayed SOC is more accurate. After calibration, the system's assessment of battery charge will be closer to reality, providing reliable basis for subsequent charge/discharge control and strategies.
Function effects:
Correct SOC deviation to avoid cases of "shown as having charge but actually empty" or "shown empty but actually has charge";
Execute charge/discharge, backup and anti-feed-in strategies based on real energy, reducing false trigger of protections or strategy anomalies;
Help customers accurately judge remaining usable energy, improving overall stability and predictability of the storage system;
This function helps customers solve the following problems:

Undervoltage Forced Charging
Function Introduction
Undervoltage forced charging is a battery self-protection mechanism used when the battery is unexpectedly deeply discharged or operated at low SOC for a long time. When battery voltage is too low, the system will automatically start forced charging to restore the battery to a safe voltage range.
Function effects:
Automatically force charging when battery energy is too low to prevent damage from undervoltage and ensure system safety;
Quickly bring battery voltage back to safe range to reduce aging and performance degradation from prolonged low-energy operation;
This function helps customers solve the following problems:
Prevent battery damage due to undervoltage and improve system safety;

Dynamic Tariff Dispatch
Function Introduction
Dynamic tariff dispatch automatically obtains market electricity prices and controls storage charge/discharge timing to match device operation with price fluctuations, helping users use storage and electricity more efficiently.
This function removes the need for manual daily price checking or strategy adjustments; the system will automatically dispatch based on price changes.
Function effects:
Dynamic tariff dispatch will automatically adjust execution periods according to actual daily prices;
By setting coefficients and additions, users can make the system-calculated price closer to the real settlement price;
Improve storage utilization and optimize electricity costs;
This function helps customers solve the following problems:
By presetting high/low price thresholds, the system will automatically charge/discharge as planned to avoid manual judgment and misoperation;
Reduce repetitive operations;
Detailed Function Description
Price Data and Calculation Rules
Required fields:
Epex spot coefficient (default 1, keep four decimal places)
Price addition (default 0, keep three decimal places)
Price displayed on the chart = Epex price × Epex spot coefficient + price addition (the page shows the calculated "Total Price").
Where:
EPEX PriceMarket price from the electricity exchange
CoefficientUsed to match actual settlement proportion
AdditionCan be used to add fixed costs (such as service fees, additional costs, etc.)
You can set the coefficient and addition according to your actual electricity bill composition so the system-calculated price better matches real settlement. When viewing a historical date: the day's historical price is calculated and saved using the last coefficient and addition set that day.
Threshold Settings (how to divide high/low price)
The system automatically tiers the day's prices using percentile thresholds to determine charge/discharge strategy periods.
Division rules are as follows:
When a period's price is lower than the "Low Price Threshold Percentile" it is judged as a low-price period;
When a period's price is higher than the "High Price Threshold Percentile" it is judged as a high-price period;
Periods between the two thresholds are judged as regular-price periods.
Here, "percentile" indicates the relative position of that period's price within the day's price sequence rather than a fixed price value. By adjusting low/high price percentile thresholds, the system dynamically divides high and low price intervals based on the day's overall price distribution.
Default low price threshold is 30% and high price threshold is 70%, with step 1%.
You can adjust percentiles using +/- buttons or by dragging the slider. While dragging, a small bubble above the slider shows the current percentile and corresponding total price data. After setting thresholds, a green (low price line) and a red (high price line) will appear on the chart to mark the intervals.
Price Chart
Mouse hover tooltip:
If there is a charge/discharge operation at that time: it will show the time, charge/discharge type, power (5-minute granularity), and price.
If there is no charge/discharge operation at that time: it will show only time and price.
Charging is shown in green on the chart, discharging is shown in yellow.
You can select historical dates to view past prices; around 12:00 noon Netherlands time you can view next day's price data.
Strategy Settings
Estimated daily profit = discharged energy × discharge price − charged energy × charge price. This result is for reference when setting high/low price thresholds.
Strategy running logic (how devices charge/discharge under high/regular/low prices)The system divides the day into three price intervals: high / regular / low. Each interval can have separate charge/discharge strategies (for example allow discharge/disable discharge, allow charge/disable charge, power limits, etc.).
Handling PV during charging:
Users can choose "Disconnect PV" or "Do Not Disconnect PV":
Choose "Yes" (Disconnect PV): PV will not participate during charging; storage will only charge from the grid (or other sources).
Choose "No" (Do Not Disconnect PV): PV supplies as usual during charging, PV will supply load first and remaining energy will go to storage; if PV is insufficient, storage will supplement from the grid.
Note: this setting only affects whether PV is allowed to participate during "charging periods" and does not change PV behavior outside charging periods.
During discharging:
Storage power is prioritized to supply loads and any surplus may be fed to the grid (if the system is configured to allow feed-in).
Within the "effective execution time range of dynamic tariff":
After discharge completes, the device enters a "discharge-prohibited" state (no more discharging during this rule period), while PV feeds to the grid at maximum possible power (try to sell as much solar as possible).
After charging completes, the device enters a "charge-prohibited" state, and PV still feeds at maximum power.
Outside the dynamic tariff time range: devices continue to follow previously effective charge/discharge logic that meets conditions (for example time-based strategies).
Time-of-day Strategy
Function Introduction
The time-of-day strategy is a pre-set charge/discharge schedule suitable for sites with clear time-based tariffs or usage patterns, or where planning storage behavior in advance is needed. It specifies how the storage system operates in different time periods. With the time-of-day strategy, the system automatically executes charge or discharge at the set times without manual real-time intervention.
After the time-of-day strategy takes effect, the system will automatically execute the corresponding modes at the set times. Modes inside and outside the time periods can be set separately and will not affect other protections and control strategies.
Function effects:
Plan storage charge/discharge behavior in advance for different periods;
Automatically switch operating modes based on time;
Improve storage utilization and optimize electricity costs;
This function helps customers solve the following problems:
By presetting time periods, the system will automatically charge/discharge on schedule to avoid manual judgment and misoperation;
Automatically charge in low-price periods and discharge in high-price periods to reduce electricity costs and increase storage profits;
Time-of-day strategy runs automatically and continuously without daily manual adjustments, reducing O&M workload and improving stability;
Note: displayed content on the time-of-day strategy page varies by device model and software version. This field explanation summarizes all fields across different versions of the time-of-day strategy page.

Diesel Generator Rated Power (kW)
Value range: 0-6553.5
One decimal place
Used to set the diesel generator's maximum output power
Diesel Generator Available Power Percentage (%)
Diesel generator available generation power = diesel generator rated power * diesel generator available power percentage
Control Mode
Dropdown options: SOC Mode, Time Period Mode, Manual Mode
SOC Mode: start the diesel generator when battery SOC is below the start SOC and stop it when SOC is above the stop SOC. Time Period Mode: set a Start Time and Stop Time; the diesel generator runs during that period and stops outside it. Manual Mode: manually start/stop the diesel generator; suitable for commissioning or special conditions
Operating Range
Start the diesel generator when the energy storage SOC is below the minimum of this range, and cut off the diesel generator when it is above the maximum of this range
Power Mode
Dropdown options: Battery Charging, Diesel Generator Power Generation
Used to select how the energy storage system operates when off-grid or in PV-storage-diesel generator cooperative mode: Battery Charging: Charge the load first according to the diesel generator available percentage, then charge the battery at fixed power, and the fixed charging power for the battery + load power <= diesel generator available generation power (diesel generator available generation power = diesel generator rated powerDiesel generator available power percentage). Diesel Generator Power Generation: The diesel generator prioritizes supplying the load, and the remaining power is entirely used to charge the battery, and the battery charging power + load power = diesel generator available generation power (diesel generator available generation power = diesel generator rated powerDiesel generator available power percentage).
Battery Charging Power (kW)
Set the power level of the energy storage battery during charging
Load Classification
Function Introduction
The load classification control function prioritizes protecting important loads based on battery SOC. When energy is insufficient, general loads are disconnected first, then important loads; when energy recovers, power is restored in sequence. Important loads are disconnected last and restored first.
Numeric relationship: General load recovery SOC > (Important load recovery SOC / General load cut-off SOC) > Important load cut-off SOC;
Function effects:
By allocating power according to priority, extend power supply time for critical loads during tight energy conditions and improve overall system endurance;
Automatically switch and tier loads to prevent production or equipment risks caused by a one-time power cut, without manual operation throughout the process;
This function helps customers solve the following problems:
Critical loads remain powered;
More durable when energy is insufficient;
Avoid sudden blackout of the entire station;
Fully automatic control, no manual load shedding required;
