6.1 Commission the Unit
1)
Remove the cover from the PV panel.
2)
Check the PV and AC voltage.
3)
If there’s DC switch, turn it to ON position.
If the unit is connected with PV panel and the input voltage is higher than 27Vdc, while the AC
grid is not connected yet, LEDs will display as below. PV power would be transferred to charge the
batteries.
PV >27V and <50V
(Off)
4)
Connects unit Grid O/P to electrical socket, it will bypass the Grid power to standalone output
automatically.
5)
Under normal operating conditions, the Grid LED turns green.
6)
Plug in load to unit standalone output, unit will feed-in the residual power to Grid to balance the
power consumption of load (If the residual power is more than load, unit would reduce the input
power to make the net power to Grid as zero).
6.2 Operation Modes
Self-consumption (On-Grid) Mode
In this mode, the unit convers PV power to charging battery and/or to balance the load power consumption;
Whenever the DC voltage is lower than 25Vdc, the unit will work in waiting state and attempt to connect
the grid by 5mins for <25Vdc and 30s for <16Vdc. In waiting state the unit continuously monitors the
internal system. Grid bypasses power to load directly.
Note: The unit starts up automatically when DC power from the PV panel is sufficient.
Off Grid Mode
In this mode, whenever the PV or Battery has sufficient power, the unit convers PV and/or battery power to
loads when Grid power is no available.
Fault Mode
The internal intelligent unit can continuously monitor and adjust the system state. If unit finds any fault
conditions, unit would shutdown immediately
PV >27V and <50V
