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, as long as sufficient
sunlight is present.
The battery can be charged by both AC mains and PV (solar) string with intelligent
charging control.
Key features:
Automatic line-to-battery switchover
Built-in enhanced AC charger
Built-in solar charger controller
Configurable output source priority, charger source priority, charger current and
so on
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
