Charger source priority: To configure charger source priority

If this inverter/charger is working in Line, Standby, or Fault mode, the charger source can be programmed as below:

Solar first:

Solar energy will charge the battery as first priority. The utility will charge the battery only when solar energy is not available.

Solar and Utility (default)

Solar energy and utility will charge batteries at the same time.

Only Solar:

Solar energy will be the only charger source no matter utility is available or not.

If this inverter/charger is working in Battery mode, only solar energy can charge the battery. Solar energy will charge the battery if it’s available and sufficient.

(Single phase 220V AC /A Hot Leg, NOT Support 110V !!! )

PowMr off-grid all-in-one solar hybrid inverter can be widely used in DC to AC areas, such as solar AC power system, vehicle system, RV power supply, security monitoring system, emergency lighting system, field power system, household power system, etc.

(Single phase 220V AC /A Hot Leg, NOT Support 110V !!! )
This PowMr off-grid solar inverter all-in-one does not support parallel operation, and does not support phase separation!
