[RE-wrenches] Conext SW4048 not charging from generator

[Dave Tedeyan]

Hi All,

I am going to service a system where the homeowner is telling me that their
Conext SW4048 had been working fine for 14 months, and then all of a sudden
recently stopped being able to charge the batteries from the generator. It
is an off grid system.

The inverter would start charging the batteries, but then about a minute
later they would hear a relay click and the charging would stop. Then it
would just keep cycling. If they turned everything off for a while, they
could then turn it back on and charge for maybe 10 minutes before it would
start cycling. They just have a crappy 4kw generator from Harbor Freight.

I have not laid my own eyes on it yet, but will be there in the next day or
two. Just wondering if anyone has experienced these symptoms and have a
good idea of what to look for first.

Thanks!
-Dave
