Eric:
The generator-based charging may impose higher currents into the batteries
than either PV charging or inverter consumption, triggering the problem.
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.

Larry,
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?

use Sunpumps - excellent company, great support. Email Joe Lines
joe@<mailto:j...@sunpumps.com>sunpumps.com for design assistance, he is
very helpful.

A few questions.
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?
