Technical FAQs 4

How do you connect a DC inverter to an AC outlet?

Connect the AC connector to the AC output port. Ensure that the AC connector is connected securely. Check the route of the AC output power cable. Before removing the AC connector, ensure that the DC switch at the bottom of the inverter and all the switches connected to the inverter are OFF.

How does an AC-coupled inverter work?

An AC-coupled inverter (also called a bidirectional inverter) converts AC power back to DC for storage. For example, when used with a 48V battery pack, it first performs DC/DC conversion before charging the battery. Similarly, when grid power charges the battery, it undergoes AC/DC conversion.

Do I need an AC switch on my inverter?

An AC switch must be installed on the AC side of the inverter to ensure that the inverter can be safely disconnected from the power grid. Do not connect loads between an inverter and an AC switch that directly connects to the inverter. Otherwise, the switch may trip by mistake.

Can multiple inverters connect to the same AC switch?

Each inverter shall be equipped with an AC output switch. Multiple inverters shall not connect to the same AC switch. The inverter is integrated with a comprehensive residual current monitoring unit. Once detecting that the residual current exceeds the threshold, the inverter immediately disconnects itself from the power grid.
