* Professional off grid solar system solution, this is a combination of big power inverter and solar controller.
* Working modes switched automatically- AC Grid bypass mode, Inverter mode, AC charging mode, solar charging mode.
* Pure sine wave output which matches wave form of AC grid no matter it on AC grid mode or Invert Mode workable on inductive load.
* MPPT controller.
* Remote control & RS232 communication port.
* Power Saver mode.
* Four stages smart charging. Charging current adjusted automatically.
* DIP switch optional: Selectable charging voltage for various battery types.
* Manual control input & output breakers.
* AC Grid priority & battery priority working mode are selectable.
* AC grid priority mode: AC Bypass supplies load when AC is normal, battery invert AC supplies load when AC is off.
* Battery priority mode: Battery invert supplies load when battery get full-charged;
* AC bypass supplies load when battery is low and at the meantime battery get charged from solar controller.
* It transfers back to battery invert mode when battery get full charged. It makes full use of solar energy and saves electricity
