1. Restart the inverter.
2. Check if L/N cables are not connected reversely in all inverters.
3. For parallel system in single phase, make sure the sharing current
cables are connected in all inverters.
For supporting three-phase system, make sure the sharing current
cables connected the inverters in the same phase, and
disconnected the inverters in different phases.
4. If the problem remains, please contact your installer.
1. Update the firmware of all inverter to the same version.
2. Check the version of each inverter via LCD setting and make sure
the CPU versions are the same. If not, please contact your
instraller to update the firmware.
3. If the problem still remains after the firmwzre is updated, please
contact your installer.
1. Check if shared cables are well connected and restart the inverter.
2. If the problem remains, please contact your installer.
1. Check if communication cables are connected well and restart the
inverter.
2. If the problem remains, please contact your installer.
1. Make sure all inverters share the same groups of batteries.
2. Remove all loads and disconnect AC input and PV input. Then,
check battery voltage of all inverters. If the values from all inverters
are different, please check if all battery cables are in the same
length and same type of material. Otherwise, please contact your
installer for an SOP to calibrate the battery voltage of each inverter.
3. If the problem still remains, please contact your installer.
1. Check the utility wiring conncetion and restart the inverter.
2. Make sure utility starts at same time. If there are breakers installed
between utility and inverters, please be sure all breakers can be
turned on AC input at same time.
3. If the problem remains, please contact your installer.
1. Restart the inverter.
2. Remove some excessive loads and re-check load information from
LCD of inverters.
3. If the problem remains, please contact your installer.
1. Switch off the inverter and check LCD setting #28.
2. For parallel system in single phase, make sure no 3P1, 3P2 or 3P3
is set on #28.
For supporting three-phase system, make sure no "PAL" is set on
#28.
3. If the problem remains, please contact your installer.
