When PV power is greater than the consumption,
and the battery capacity is low, the PV will supply
power to the load and charge the battery at the
same time.
When PV power is less than the consumption,
and the battery capacity is high,PV and battery
suplay power to the load at the same time.
The grid supplies power to the load and charges
the battery when the battery capacity is low.
SOL (Solar first):
Solar energy provides
power to the loads as
first priority.
UEI (Utility first):
Utility gird will provide
power to the loads as
first priority.

When PV power is less than the consumption,
and the battery capacity is low, grid supplies the
load, PV charges the battery, if there is rest PV
power, supply the load.

UFox-X-US Series User Manual
（5）Connect the communication cable (BMS-Inverter) between the inverter
and the battery, and connect the communication cable (Link out-Link in)
between the batteries (the shaded line in the figure), if you hear a "click" sound,
the connection is in place; when disassembling, press and hold the clip of the
RJ45 port to pull it out.
（6）Set the battery communication address, the address of battery that
communicates with inverter must be 1, and next several batteries should be
2,3,4….
Below are the explanation of battery address and dip switch, 1 means ON, for
example, if the battery address is 3, the pin 1 and 2 are ON, 3 and 4 keep still.
