Connect the battery to the inverter using the battery power
cable provided. Ensure that the battery is fully charged and has
the correct voltage rating.

Battery Power Cable Connection

Connect the battery power cable to the positive and negative
terminals of the battery. Ensure that the cable is securely
attached and does not touch any other metal objects.

Lithium Battery Connection

If using a lithium battery, connect it to the inverter according
to the manufacturer’s instructions. Ensure that the battery has the
correct voltage rating and is compatible with the inverter.

AC Input/Output Connection

Connect the AC input/output cable to the inverter and ensure
that it is securely attached. The AC input/output cable should be
connected to a suitable power source, such as a generator or
utility grid.

PV Connection

Connect the PV connector to the inverter and ensure that it is
securely attached. The PV connector should be connected to a solar
panel or array with the correct voltage rating.

3.1 AC First: During this setting time, system will use AC to take load, use solar power to charge the battery first. If there is extra solar power, extra solar power will take the load. When out of the setting time, system will use solar and battery to take load first until the battery voltage/SOC is lower than On Grid EOD settings, then it will use AC to take the load.

According to Time: During the setting time, system will use AC to charge the battery until battery full and battery will not discharge during the setting time.
According to Battery Voltage: During the setting time, system will use AC to charge the battery if battery voltage is lower than AC Charge Start Battery Voltage and will stop when Voltage is higher than AC Charge End Battery Voltage. And battery will not discharge during the setting time.
According to Battery SOC: During the setting time, system will use AC to charge the battery if battery SOC is lower than AC Charge Start Battery SOC and will stop when Voltage is higher than AC Charge End Battery SOC. And battery will not discharge during the setting time.
