You're not far from me, so I know that the temperature at the site
has been well below freezing at night.<br>
After running a series of cheap generators here for many years I can
tell you that there's likely water built up at the bottom of the
fuel tank.<br>
This freezes and constricts fuel flow which of course affects
generator rpm and thus voltage and frequency.<br>
<br>
So check for that but as everyone else has said so well, it's the
generator.<br>

<div>Dave, do you know if the Conext will log an error if the
relays have actually been damaged? I am hoping that there will
be something in the error logs that will help identify
whether there is an inverter issue now, or whether the issue
lies with the generator input.</div>

<div>Have them turn down the AC input and see if that fixes

<div>Sounds like a classic generator issue.</div>
<div>As to why? When did they last change the oil, air

<div dir="ltr">Hi All,
<div><br>
</div>
<div>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. </div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
