the meter is spot on. I would have
expected higher numbers than STC but did not know it would be that much.
Others may have a multiplier to use with STC for altitude that could confirm
your numbers.

Battery connections are tight with the inverter pulling around 160 amps DC for

sources of potential are bonded
back to source there is only shock hazard by getting between hot and neutral.
Also, if a fault does occur with proper bonding the system will drain itself to
dead fairly quickly and a summary diagnosis should find the fault as the

There may be adjustment on the fuel setting on the genset but he probably has

I've seen lots of gensets wander that much and more. When inverters are

If the connections were not tight enough heat could have built up to melt the
