Step 1: Check the input voltage of PV array modules. This system is applied with One strings of
PV array. Please make sure that the maximum current load of each PV input connector is 1 8 A .
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the system before
wire connection.
Step 2: Disconnect the circuit breaker and switch off the DC switch.
Step 3: Insert PV+/PV- according to the polarity indicated on the terminal, and tighten the terminal screw.
3.7 Emergency Procedure
When the energy storage system appears to be running abnormally, you can turn off the grid-connected main
switch that directly feeding the BESS , and turn off all load switches within the BESS ,turn off the battery
switch at the same time. To prevent a potentially fatal personal injury, if you want to repair or open the
machine after the power is switched off,please measure the voltage at the input terminals with a suitably
calibrated voltage tester.Before working on this equipment, please confirm that there is no grid electric supply
to the BESS! The upper cover plate cannot be opened until the DC-link capacitance inside the battery modules
discharges completely about 15 minutes later.
3.7.1 Emergency Handling Plan
1.Disconnect the AC breaker.
2.Check the control power supply. If it is OK, return the power supply to find out the reason.
3.Please record every detail related to the fault, so Factory can analyse and solve the fault. Any operation of
equipment during a fault is strictly forbidden, please contact Factory as soon as possible. 4.As battery cells
contain a little Oxygen inside and all cells have got explosion-proof valves,explosion hardly happens.
5.When the indicator light on the battery shows a red fault, check the fault type through the
communication protocol, and contact our after-sales service personnel for advice.
Make sure the wires are securely connected.
