PRODUCT OVERVIEW
This is a DC-to-AC inverter with integrated solar battery charger, which can be used as a long
run-time UPS (Uninterruptible Power Supply), an energy- saving solution or an automotive
inverter (hereinafter referred to as “inverter").
The inverter accepts input power source from AC mains (utility), battery, and PV (solar)
string and switches between various operation modes automatically depending on the
operational conditions.
When used as an UPS, battery or PV (solar) string act as back-up power source to supply loads
during the outage of AC mains.
When used as an energy-saving device, the PV (solar) string can be set as priority to supply the
loads without consuming the power from AC mains, if enough sunlight is present.
The battery can be charged by both AC mains and PV (solar) string with intelligent charging
controller.
Key features:
•Automatic line-to-battery switch over
•Built-in enhanced AC charger
•Built-in solar charger controller
•Configurable output source priority, charger source priority, charger current and soon
•High efficient DC-to-AC conversion with minimized energy loss
•Rack design & wall-mounted design for flexible installation
•Intelligent 3-stage charger control for efficient charging and preventing
overcharge
•Auto restart upon AC recovery
•User-friendly LCD and LED indications with setting function
•Smart temperature compensation technology to extend battery life
•Multiple protections: low battery alarm, low battery shutdown, over charger protection,
overload protection, over temperature protection, short circuit protection
