the Magnum with the second string? We can bypass it and feed the main panel
instead of the sub but will lose the second array output in a power failure.

We built a display for a Science Center shining a 350 watt halogen bulb onto a
20 watt module. We could get .4 amps out of the 12 volt panel. No matter how
large the array it can't be done with 60 lumens because the light disperses at
the same rate that the array surface area increases.

William,
If the connections were not tight enough heat could have built up to melt the
bolt mount. It is not all that uncommon and confirms the importance of properly
torqueing all connections.

I've seen lots of gensets wander that much and more. When inverters are
throwing full amperage at a battery bank during bulk charge and the genset is
set to 60hz it could easily be at 62hz at the tail end of the absorbtion charge
when the load has tapered off.

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

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
culprit.

s are the only discharge path for this surplus power now. So now
the issue is finding some way
to regulate that backfed current to protect the batteries. And that brings us
back to our discussion of frequency variation, dump loads, relays, etc.

That description sounds like some old modules I used to have. I thought they

Hard to believe we have 4 of their controllers over several months with the

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