6 FAQs about [Solar panel bus voltage is high]
Is there a correlation between high PV voltage and high bus voltage?
There seems to be a correlation between high pv voltage and the high bus voltage... My panels seem to be hitting a voltage a bit higher than expected up to 118 and 120 volts. Mppt operating range is 60 - 115 but the voc is 145 volts. So to my mind the inverter should be able to deal with the over voltage and clip the solar accordingly.
Why does my inverter detect high DCV on internal bus?

How do I know if my inverter has a high DC bus fault?
I also re-tested the first inverter with the high DC bus faults using a meter with max/min capture. The unit faults on high DC bus fault but the MAX DC pv voltage was 364. One thing I did notice was the unit with the high bus faults has the green status led blinking all the time. The other unit has a solid green status led.
Can a solar inverter handle over voltage?
Mppt operating range is 60 - 115 but the voc is 145 volts. So to my mind the inverter should be able to deal with the over voltage and clip the solar accordingly. Any suggestions guys? There seems to be a correlation between high pv voltage and the high bus voltage...
What voltage does a solar inverter have?
The bus voltage is 373-400V in these inverters. This has to go over 500V to get this error message. PV over voltage. How many solar panels do you have in serial, Voc, Vmpp, V temperature % ? Backfeed on the AC out (load) side. A generator, a bad UPS, or a grid-tie (micro) inverter ? Earth leakage.
What causes high DC bus voltage when battery is full?
Usually "high DC bus voltage" is due to high PV voltage when battery is full. That's what I would be checking. Battery is only 70% full when faults occur. If I can do it, you can do it. If you have any type of monitoring, can you check what the DC bus voltage was at the time of the fault? It's probably just a momentary spike.
