That's right about the unprotected DC + main. Trace used the
inverter GJ, so turning off DC loads required turning off the DC to
the inverter - which meant reprogramming it afterward. And it used a

Look at HDPE. It is a fused pipe, very tough, flexible, available in a

Thanks, everyone. I see I'm not the only one juggling competing concerns

Dave, it's 6 T-105s and over the winter the only load is the CC and
inverter. Temperature is unknown, though likely gets to -20F. There is
insulation, not that it does any good if they are not charging to capture
some heat.

HI Dan,
All the big three have the same wiring diagrams with a positive buss and then
breakers going out from there.
And yes there is no main disco for the DC branches.
But if your point was that the fuse could/will blow and then you have the

Hi Allan and Jay,
I second the golf cart battery option. Trojan T-105s seem to be the
most bang for the buck. An 800 W array wouldn't stir up the
electrolyte sufficiently in an L-16. Maybe the backup generator
would. What all is she running?

Enphase don’t have one.
This is on my old house. Still has a AEI-GC-1000.
The modules have got to come off as well as they are old mobil’s.
All just about dead.
I’ve got a good deal on 72cell, 280 watt modules,

Hey Dan,
Interesting voltage numbers. How many T-105's in this system and what is the
load? What is the temperature of the battery bank?
Thanks,

Esteemed Wrenches;
This creeps me out too and sometimes causes lack of sleep.
The Midnite Solar power panel install manual shows no OCPD on in DC + main
from battery bank to power panel. Easy to wire the main DC breaker to
control those conductors, but then you have a "self destruct" switch if

It's ALWAYS good practice to install a current limiting fuse at the battery
