fully protected from over current of Grid. The recommended spec of AC breaker is 50A/400V
for the three-phase unit, 100A/400V for the single-phase unit.
CAUTION!! There are two terminal blocks with“AC OUTPUT” and “GRID” markings. Please do
NOT-misconnect load and grid connectors.
WARNING! It's very important for system safety and efficient operation to use appropriate
cable for AC connection. To reduce risk of injury, please use the proper recommended cable

Please follow below steps to implement AC connection:
Three-Phase Unit Connection
Notice: Single-phase and three-phase unit wiring is not the same, cannot be mistaken,
otherwise it will cause a short circuit.
Notice: Before connecting the grid to this unit, disconnect the PV and
battery from the unit,And disconnect the main switch on the grid side.
Notice: Before connecting the load to this unit, disconnect the PV,
battery, and grid from the unit.
Step 1: Remove insulation sleeve 8mm for conductors and crimping
terminal and heat shrinkable sleeve(25mm).
Step 2: Connect the load phases R, S, T and N to the terminals marked "AC OUTPUT" -R, -S,
-T, -N on this unit. Tighten the terminal screws.
Step 3: Connect the R-phase, S-phase, T-phase and N-phase of the three-phase grid to the
terminals marked "GRID" -R, -S, -T, -N on this unit. Tighten the terminal screws.
Step 4: Make sure the wires are securely connected.
Notice: be sure to connect the N line to this unit.
Single-Phase Unit Connection
Step 1: Remove insulation sleeve 8 mm for conductors and crimping terminal and heat
shrinkable sleeve(25mm).
Step 2: Connect the terminal marked "AC OUTPUT" -R, -S, -T of this unit with an AC wire. Wire
as shown below.
Step 3: Connect the terminal marked "GRID" -R, -S, -T of this unit with an AC wire. Wire as
shown below.
Step 4: Connect the L phase of the load to the terminal marked "AC OUTPUT" -R, -S, -T in this
unit. You can connect one terminal, two terminals or three terminals at will. And
connect the N phase of the load to the terminal marked "AC OUTPUT" -N on this unit.
Tighten the terminal screws.
Step 5: Connect the L phase of the grid to the terminal marked "GRID" -R, -S, -T in this unit.
You can connect one terminal, two terminals or three terminals at all. And connect
the N phase of the grid to the terminal marked "GRID" -N on this unit. Tighten the
terminal screws.
CAUTION: Important
Be sure to connect AC with correct polarity. For the three-phase unit, if the R-phase, S-phase
and T-phase of the grid are connected in reverse, this unit will cause a connection failure.
For the single-phase unit, if the L-phase and N-phase of the grid are connected in reverse,
this unit will cause a short circuit.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart
because it's required to have enough time to balance refrigerant gas inside of circuits. If a
power shortage occurs and recovers in a short time, it will cause damage to your connected
appliances. To prevent this kind of damage, please check manufacturer of air conditioner if
it's equipped with time-delay function before installation. Otherwise, the unit will trig
overload fault and cut off output to protect your appliance but sometime it still causes
internal damage to the air conditioner.

by your household
appliances. Any excess
power generated is not
sold back to the grid, but
stored in battery.
PV energy is charger
