The inverter is built with automatic PV and utility power wakeup feature.
⚫ When the power switch is in power off, and qualified PV input, the PV charger will be activated, and
the rest part of the inverter will remain powered off. In this mode, the utility power can only illuminate
the LCD, it can’t charge batteries.
⚫ When the inverter shuts off due to low battery voltage, and the switch is kept on “on” position, the
inverter will use qualified utility power or PV power to charge batteries and wake up at “cold start
voltage” to discharge the battery to provide AC output.
⚫ If the inverter is set in SOL or SUB, the automatic wake up feature will charge battery close to “Utility
to Battery switch” voltage, and then cut off utility charger, switch to DC to AC model.
