Charging voltage is

too high

1. Check if the

connection between

battery and inverter is

well.

2. Make sure battery

condition is ok.

3. Then, restart the

inverter.

4. If error message

remains, please contact

your installer.

Overload fault

1. Remove exessive

loads. Be sure that total

connected loads are less

than maximum power

consumption this

inverter can support.

2. Then, restart the

inverter.

Battery

disconnected

1. Check if battery cable

is connected ﬁrmly.

2. If error message

remains, please contact

your installer.

Inverter current is

too high for a long

time

1. Remove exessive

loads.

2. Then, restart the

inverter.

Short circuited on

inverter output

1. Turn oﬀ the inverter.

2. Disconnect AC circuit

breaker ﬁrst. Then,

disconnect DC circuit

breaker and then

disconnect the loads.

3. Please check if load

circuit is ok. After

removing the error, turn

on the PV DC breaker

and battery breaker.

4. Turn on the inverter.

5. If error message

remains, please contact

your installer.

Fan fault

1. Please check if fans

are runing ok.

2. If fans are runing ok,

please shut down

inverter ﬁrst and then,

restart it.

3. If fans are stop runing

or error message

remains after restart the

inverter, please contact

your installer.

OP Current Sensor

fault

1. Shut down the

inverter completely.

2. Restart the inverter to

see if it’s ok.

3. If error message still

remains, please contact

your installer.

Charger failure

1. Shut down the

inverter completely.

2. Restart the inverter to

see if it’s ok.

3. If error message still

remains, please contact

your installer.

Version mismatch

between controller

board and power

board

1. Shut down the

inverter completely.

2. Restart the inverter to

see if it’s ok.

3. If error message still

remains, please contact

your installer.

Reverse connection

of input and output

wires

1. Shut down the

inverter completely.

2. Check if grid wires are

connected to AC output

terminals.

3. If mis-connected,

re-connect it correctly.

And turn on the inverter

again.

4. If error message still

remains, please contact

your installer.
