Hi Jeremy,
I run into situations this this all am the time. Misinformed DIY work
strikes again. Luckily, as PV installers, we have an out. We can quickly
and easily point to the NEC and tell the customer that there are certain

I’ll say it again: The most important clients are the ones you turn away. The
penny pinching, pound foolish, never satisfied, paranoid, DIY-without-asking,
ear bending, time sucking, slow paying nightmares that we have all had. The key
is to see the warning signs on the way in, a skill that come
I tackle this sort of work frequently, as I only work off the grid and
mostly deal with smaller systems for cabins, fishing and hunting lodges,
and such, often for land buyers/sellers, Realtors, and insurance agents. By
far the most common violation I see out in the bush is lack of a vented
battery
Many moons ago I asked this same list the same question and got about the same
answer. I tried to help one customer, got sued for not “listening” to them when
they told me what to do, even though we fixed the issue. Spent money on
attorneys, missed days of work.
That was it for me ever doin
It shows you have been in business for 15 years? RUN don’t walk. REDO once you
put a wrench to this YOU and your 15 years can quickly find yourself out of biz.

Thanks guys, it was more of a check to see if I’m just being too, oh I don’t
know - cautious. We get a fair number of these calls and we do exactly as you
all do, i.e. either start over or pass more often (these types of systems are
done in shoe strings anyway so they don’t want to hear our ans
Wrenches,
You can have 4800W on L1 and 0W on L2. It has huge 240V peak power. But you are
correct that some 120V inductive loads >3/4hp can be an issue. We recommend
rewiring those massive motors to 240V (most are convertible on the motor). The
1400W limit is with DC Loads. A heat gun on high
Ditto to Ray and I would add that you have no idea how the batteries were
treated or mistreated. I would insist on replacing the batteries or having
a very clear and strong disclaimer that you take no responsibility for the
condition of the batteries or their longevity.
Unfortunately, I had a simi
I concur with Dave: Delete and start over. Its actually faster and
cheaper than trying to figure out why they did things the way they did,
and having callbacks where you discover more problems you didn't see the
first time, etc. I'll reuse as much of the stuff as I can, even cable,
but that n
Since it would not pass a home insurance or building department
inspection, it would have to be start fresh. Once you get your hands on it,
it is yours. Good Luck!

Ummm, I think you need to add run a normal battery charge cycle first to
your list. Pretty dangerous to EQ a bank without doing bulk/absorb first,
especially if you are at a clients house! You really do not know the state
of the battery!

Bob:
We are way beyond putting our faces over an open battery cell with a
flashlight. We use professional auto-stop fill systems from Philadelphia
Scientific. I highly recommend the X-Gun with hydrofill cart.

Thanks though
That’s the procedure I’ve been using for years William, it gives us the best
chance of being accurate.
Just as a note I get a 2 gallon sprayer from Home Depot or somewhere (get the
one with the plastic rod, the spark show is not worth it) and use that to put
distilled water into the batteries.
