General Mode
In this working mode, when the power from the
PV array is sucient, PV power will supply the
loads, battery, and grid in the order ofloads
rst, batte second, and grid last.
(You can set the power to the grid to 0W when
the local grid doesn’t allow inverter power to
feed to the grid).
When the PV power is insufficient, the battery
will discharge to supply loads, and the grid will
join in if the battery is not enough to supply
loads.

Peak load Shifting (Load Shifting)
Set the maximum power Pmax (kVA) contracted
with the grid.
When the load consumption is less than the
Pmax, the PV will charge the battery first, and
the grid supplies the load. When the batte is
full, PV will supply the load together with the
grid, but the batte doesn't.
When the load consumption exceeds the Pmax,
the inveer will take power from the batte and
PV to supply power to the load to compensate
for the power that exceeds the Pmax.
*To realize the “Peak load Shifting” function, the load power that exceeded Pmax has to be within the inveer
max output power, otherwise, the inveer will only output the max power which allowed.

In this working mode, the inverter will use the
power from PV or grid to charge the battery
until it is fully charged, and as long as the grid is
there, the batte won’t discharge.
When the grid fails, power from PV and batte
