Sunsynk Fault Codes

Thanks for response Groots.

The battery in question was bought 3 months after the first one.

No matter if you change it as master or slave, every few days it's got that warning.

Sometimes 2-3 weeks will pass without any warning.

If it is in a warning state, it stays there. Does not go away.

By just switching your grid supply off and back on, it comes out of the warning straight away.

Then immediately starts charging again. (blinking Run Led)
