FAQs 3

What is a Huawei Sun series Smart string grid connect inverter?

HUAWEI SUN Series Smart String Grid Connect Inverters are of transformerless design for the management of hybrid solar powered PV/AC mains power supply installations.

How do I change the grid connection status of the inverter?

The grid connection status of the inverter is switched by using the Backup Box. The critical load power does not exceed the max off-grid output power of the Inverter. You can add inverters and batteries to increase capacity. A maximum of three inverters can be cascaded.

How many inverters can be connected to a smart dongle?

When the grid charging function is enabled, the surplus power generated by one inverter can be used to charge the other inverter. Each L1/LC0/M1 can connect to a maximum of two ESSs, and each MB0 can connect to a maximum of four ESSs. In the Smart Dongle networking scenario, a maximum of three inverters and six ESSs can be connected.
