3. After inserting the AC output wires observing the polarity marked on the terminal block, proceed to tighten the
screws. The protective earth (PE) conductor ( ) must be connected first.

4. Verify that that all wire connections are properly secured.
Recommended AC conductor size
When selecting PV modules, observe the following parameters:
• Never exceed the maximum permitted open-circuit voltage (V
OC
), specified for the PV array.
•The open-circuit voltage (V
OC
) of PV modules should be higher than the minimum specified for the battery.
CAUTION:
Follow the correct polarity when connecting AC wires. If
L
and
N
wires are reversed, it may cause a utility short-circuit
when the inverters are in parallel operation.
NOTE:
Appliances such as air conditioners often require at least 3 minutes to restart after a short-term power outage
(time is required to balance the refrigerant gas in inside circuits). In order to protect your air conditioner, consult the
manufacturer whether they have already provided a time delay function before the installation. Otherwise, the inverter
will trigger an overload fault and shut off its output to protect your appliance. Even so there is some risk of damage to
the air conditioner.
