The generator-based charging may impose higher currents into the
batteries than either PV charging or inverter consumption, triggering the
problem. <br><br>
Melted battery terminals are not uncommon. You must have washers
under your bolt heads with lead flanges. Otherwise the bolt heads
sink into the lead, loosening connections. All mating surfaces need
to be newly wired brushed just before assembly. Battery connections
need to be re-torqued annually.<br><br>

<font face="arial" size=2>Thanks for your reply. For some reason the
schematic I received from the tech at Atkinson did not show any wires
being connected to pins 9 & 10 and as I'm a literalist I did not make
those connections. After I received your (and other) feedback I connected
gen power to those pins and the AGS seemed to function fine. Within 2
days the customer called me back saying his genny was shutting off after
20 mins of runtime. I told him to disconnect or reprogram one system
component at a time to find the fault source. Before a fault source was
determined, he observed that two batteries in his bank were experiencing
the "battery terminals melting into the battery casing" (as was
texted to me by the customer). I have no idea how a GSCM interface would
cause or allow an overcurrent fault at the batteries but the timing of
the installation seems to indicate that the AGS is at fault. Ever heard
of this before?<br>

<blockquote type=cite class=cite cite>A few questions. <br><br>
I have a customer who really wants a solar-direct pool pump for his home.
Medium size in-ground pool and I'd like the pump to be strong enough to
lift to the solar pool panels (12 ft lift above pool level). I'd like to
offer him hardware that is at least one notch above experimental
beta-test. I remember the SunCentric from several years ago, but not sure
how durable that turned out, and I was having trouble a vendor for it
now. Any suggestions for today with some favorable track record? Or
suggestions on what to avoid? <br>
