Try lowering the max charge amps incrementally.

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
