Program 08: AC Output Voltage
The AC output voltage between two hot lines (or hot and neutral for single phase models) can be set to
208V, 220V, 230V and 240V.
Accordingly, the voltage between each hotline and neutral is 104V, 110V, 115V and 120V.
Program 09: AC Output Frequency
The AC Output Frequency can be set to 50Hz or 60Hz.
Program 11: Maximum Utility Charge Current
If Li is selected in program 5, this program can’t be manually set up.
The solar charger has higher priority than the utility charger, if the max charging current and utility charger
is set to the same value, the solar charger will still work.
If setting value in Program 02(Total Charge Current) is smaller than that in Program 11(Utility Charge
Current), the final charging current is set according to Program 02 for utility charger.
No matter the AC output frequency is set to 50Hz or 60Hz, the acceptable AC input frequency for the utility
charger is 45-65Hz.
If the AC input frequency drops out of the 45-65Hz range, the inverter will transfer to battery. The AC input
has to return to 47-63Hz to activate the utility charger.
Program 12: DC to AC Transfer Voltage
The setting works when program 01 is in “SBU Priority” or “Solar Priority” Mode.
The battery SOC will be displayed when BMS communication is established.
Program 13: AC to DC Transfer Voltage
The setting works when program 01 is in “SBU Priority” or “Solar Priority” Mode.
The battery SOC will be displayed when BMS communication is established.
Program 14: Charger Power Source Priority
14:CSO
Solar Priority
⚫ Solar energy will charge battery as the priority.
⚫ Utility will charge battery only when solar energy is not available (lost).
14:CUt
Utility Priority
⚫ Utility will charge battery as priority.
⚫ Solar energy will charge battery only when utility power is not available (lost).
