OPERATION MODES
3.1
UPS System
The inverter is used as an
UPS.
This operation mode is used for systems that have the grid
available as the main AC supply. The grid will supply the load. When the grid supply is
interrupted or lost, then the inverter switches to inverter mode. The batteries power the load
via the inverter circuitry. When the grid power returns, the load reconnects with the grid.
The internal charger charges the batteries when the grid is available.
For this mode of operation select
“
UPS
”
in the setup menu.

3.2
Off-Grid System (No Grid Supply )
When the inverter is used as an
OFF-Grid
solution
,
the inverter runs in inverter mode. The
batteries power the load via the inverter circuitry. Renewable energy charges the batteries.
For this mode of operation select
“
UPS
”
in the setup menu.
A generator can be connected to the inverter to assist with charging and supplying the load
when required.

3.3
Grid Assisted Solar Power System
In a Grid assisted system the inverter mainly runs in the inverter mode and the batteries
power the load via the inverter circuitry. Renewable energy charges the batteries. The load
runs from battery power until the batteries have discharged to a set level. At this level, the
load is disconnected from the batteries and the load is connected to the grid. As soon as the
batteries are charged to a set level, the load disconnects from the grid and the load is
powered from battery power.
For this mode of operation select
“
Solar Control
”
in the setup menu.
