System Power-On and Power-Off
System Power-On
- Before powering on the energy storage system, please ensure the PV switch & all AC and BAT circuit breakers in the system are switched OFF and cannot be reactivated.
- Never power on the energy storage system without the correct and reliable installation and electrical connection.
Complete power-on according to the following steps.
- Turn on the BAT BREAKER on the high-voltage box
- Turn on the AC BREAKER.
- Switch on the PV SWITCH on the inverter
- Press the ON/OFF button
Note: In historical versions, the inverter does not have an ON/OFF button, so Step 4 may be skipped.
After the system DC side is powered up, switch on the AC side breaker at the user end.
System Power-Off
- After the energy storage system is powered off, the remaining electricity and heat may still cause electric shocks and body burns. Please put on protective gloves and operate the product 5 minutes after the system is powered off.
Prior to system shutdown, switch off the user's AC side breaker first, then perform power-down in accordance with the steps below.
- Turn off the BAT BREAKER on the high-voltage box
- Turn off the AC BREAKER.
- Switch off the PV SWITCH on the inverter
- Press the ON/OFF button
Note: In historical versions, the inverter does not have an ON/OFF button, so Step 4 may be skipped.
If DC inputs are accidently reversely connected or inverter is faulty or not working properly, it is NOT allowed to turn off the DC switch. Otherwise it
may cause DC arc and damage the inverter or even lead to a fire disaster.
The correct actions are:
*Use a clip-on ammeter to measure the DC string current.
*If it is above 0.5A, please wait for the solar irradiance reduces until the
current decreases to below 0.5A.
*Only after the current is below 0.5A, you are allowed to turn off the DC
switches and disconnect the PV strings.
* In order to completely eliminate the possibility of failure, please disconnect
the PV strings after turning off the DC switch to avoid secondary failures due
to continuous PV energy on the next day.
Please note that any damages due to wrong operations are not covered in
the device warranty.
