FAQS 3

What happens if an inverter ground fault is unresolved?

However, even when disabled, a ground fault still presents a fire or shock hazard if left unresolved. In some cases, an inverter ground fault warning can be a false positive, or even caused by an internal failure in the device itself. The first step is to confirm whether an actual fault exists.

Do inverters shut down if a ground fault is detected?

Luckily, most modern inverters actively monitor for ground faults and will shut down the system when one is detected. However, even when disabled, a ground fault still presents a fire or shock hazard if left unresolved.

Can a ground fault cause electrical imbalance in a PV system?

tring 1 and the grounded module frame. Consequently, the fault will cause electrical imbalance among the PV a of the PV system under a ground faultGenerally speaking, every module, string, and whole array, whether in normal or fault condition, has its own I-V characteristic
