MPP solar LV6048 bus voltage is to high

[Eco@242]

Hi to everyone.
I'm Constantine. I'm new to the forum and to solar.
I am trying to finally back feed to the grid, but this fault code came up(08 buss voltage is too high). How do I fix this?

More things can cause the Error 08
The bus voltage is 373-400V in these inverters.
This has to go over 500V to get this error message.
(or at least in the EU version ... so I am not sure this is the same in the LV inverters )

What can cause it:

1. PV over voltage. How many solar panels do you have in serial, Voc, Vmpp, V temperature % ?
2. Backfeed on the AC out (load) side. A generator, a bad UPS, or a grid-tie (micro) inverter ?
3. Earth leakage. Mainly in rainy days if a solar panel leaks to earth.
4. An old firmware bug caused regularly in 2-6 am to stop inverter with error 8.
   Try to set 11-max utility charge current to 2A ... and 16-charger source priority to CSO (solar first)

Hey,

Thanks mrzed001.
I think your rite about the backfeed part. Will have the electrician double check.

Hi everyone, I'm experiencing this problem Error code08, It happens around 0300hr to 0500hr everyday.... I have confirm the utility grid power is stable during that time period.
Is there a solution to this problem?
