03
DC bus voltage falls below the lower
threshold
None
1. Turn off the inverter using the main switch.
2. Measure the voltage at the battery and at the cabling above and below the
battery disconnect to make sure voltage is within 44 to 58Vdc.
3. If the voltages are in range, check if the battery went into protection mode.
4. Turn the inverter on. If the error remains, contact your installer.
04
Parallel setting is not correct
None
1. Check the parallel setting and mode setting.
2. Check the communication cable between stacking system.

Battery discharging current exceeds
the upper threshold
On: 1s
Off: 1s
1. Turn off the inverter using the main switch.
2. Make sure the Grid and Load terminals are wired properly.
3. Turn the inverter on. If the error remains, contact your installer.
06
Battery charging current exceeds the
upper threshold
On: 1s
Off: 1s
07
Short circuit on PV1 input
None
1. Turn the inverter off and then back on using the main switch.
2. If the error remains, have your installer check the PV array for short circuits.
08
Short circuit on PV2 input
None
09
Short circuit on AC
output
Continuous
5. Turn off the inverter using the main switch.
6. Turn off the load breaker.
7. Make sure L1, L2 and N on the load circuit are not shorted.
8. Turn the inverter on. If the error remains, contact your installer.
10
Leakage current CT fault
None
1. Turn off the inverter using the main switch.
2. Turn the load breaker off.
3. On the essential loads, check all appliances are not leaking current. If so, unplug
the appliance safely.
4. Turn the inverter on. If the error remains, turn the Grid and PV breakers off.
●
On the PV side, measure and make sure the impedance of PV1+, PV1-, PV2+
and PV2- to ground and to each other should be an open circuit.
●
On the Grid side, measure and make sure the impedance of L1, L2 and N
relative to ground and to each other should be an open circuit.
5. Turn the inverter off, then back on. If the error remains, contact your installer.
11
DC/DC Current Sensor fault
None
1. Turn the inverter off and then back on using the main switch.
2. If the error remains, contact your installer.
13
PV Current Sensor fault
None
14
EEPROM read failure
None
15
Communication with main & secondary
controllers are interrupted
None
16
Over temperature fault
On: 1s
Off: 1s
1. The internal temperature is too high.
2. Make sure the inverter is properly ventilated by removing any obstruction around
the vents.
3. Make sure the fans are working.
4. Turn off the inverter using the main switch and let it cool down for 10 minutes
before turning it back on.
5. If the error remains, contact your installer.
17
PV input voltage exceeds the upper
threshold
None
1. If the PV V
OC
is higher than 500VDC, contact your installer.
2. If the PV V
OC
is less than 500VDC, turn off the inverter and restart it after 5
seconds. If the error remains, contact your installer.
18
Over power protection
On: 0.25s
Off: 0.75s
1. The Grid/ Load power has been over 7.5kW for 30s.
2. Turn off the inverter using the main switch.
3. Make sure the load is lower than 5kW
4. Turn the inverter on using the main switch.
5. If the error remains, contact your installer.
19
PV insulation resistance is too low
None
1. Turn off the PV breaker.
2. Check if the impedance between positive and negative poles to the ground is
greater than 1MΩ.
3. If the impedance is lower than 1MΩ, contact your installer.
20
Battery charging voltage is too high
None
1. Turn off the inverter using the main switch.
2. Make sure the connection between battery and inverter has firm and solid
contact.
3. Make sure the battery voltage is within manufacturer’s specifications.
4. Turn the inverter on. If the error remains, contact your installer.
21
Fan fault

Overload
On: 0.25s
Off: 0.75s
1. The load exceeds available output power. This error will disappear once load is in
a acceptable range.
2. If the overload occurs for more than 40 seconds, the inverter will automatically
restart. The inverter only allows 3 overload restarts within 5-minute intervals.
3. If the inverter is constantly restarting due to overload, you should decrease your
load.
23
