[RE-wrenches] GSCM-mini with Honda EM5000SX

[William Miller]

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.
