Hello.
I have installed h3 12.0e inverter. It give me error 64 dc bus volt high but the votlage is only 220 in one string and 300 in other string connected to different mppt. What could be the reason for it?
H3 12.0e error 64
The fact that there is 0 current and assuming it's daytime might be a issue with the pv wiring.
If that voltage and current is correct then I would first upgrade the firmware to latest and then make sure the pv wiring is correct as per the fox manual. You can't parallel panels. Fox only support simple strings.

Thanks for the replay. Does the H3 inverter need smartmeter to run even if i dont have batteries? In settings i've turned meter off. And u physically don't have it installed.Will wrote: Mon Mar 31, 2025 9:50 am The fact that there is 0 current and assuming it's daytime might be a issue with the pv wiring.
