Wrenches
have any wrenches used the Grace Solar mounting rail/clamp assembly? The
clamps are drop-in, like T-head bolts but clamp against both edges of the
rail. The rail allows the same clamps to attach on either the top edge or
side. Their www site didn't list any US distributors.

I wanted to add to the rack discussion that Unirac has a clip ( bottom mount
clips) that allow you to use their rails but mount via the module mounting
holes.
Very slick design, I've used it a bunch.
Very secure and of course you work from the bottom.

DP&W has a similar thing, but it's a clamp which grips the module frame from
underneath.

Consider not moving or selling your PV powered home. Making your PV powered
home your retirement home is a better investment than a savings CD and
definitely a hedge against increased grid electricity prices for retired people
on a fixed income. Plant some roots and lead your neighborhood by exa
You hit a nail on the head. We hear very often older customers saying
that they want to a) make sure their presumed future widow is taken care
of, or b) want to leave a self-sustaining home to their kids. I think
these are very valid and intriguing reasons to go solar.

That opens up a whole other discussion: why do people think solar is so
troublesome to get installed. Is it the perceived cost? Selecting a contractor?
Learning the basics? If we’re listening to the anecdotal evidence, the value
seems to be from having someone else deal with the _hassle_ of gett
I'm curious of others experiences with testing "new" batteries right from the
mfgr, before putting them into service. I'm not talking about load testing, i
mean just basics...voltage, specific gravity and electrolyte level.
I recently received some batteries (24 x 2V) and before putting them to
Hi Benn:
Perhaps those batteries have just been sitting a little while, and need a
recharge. Generally speaking, if you find that the batteries test reading are
a
little low, they are probably just a little discharged. After recharging the
batteries, test them again. If those readings ar

advise that you add neither water nor acid to the new cells. Check with the
mfr, but most of the serious mfrs are using robotic fill equipment that is
very precise.
If some of the cells are older stock they may have self disc

Hi, Benn~
When the batteries are chemically discharged, the plates absorb some of the
volume of the electrolyte...and that "lowers the tide". Upon recharge the
chemicals that had been absorbed into the plates are driven back into
solution...and that "raises the tide".
This is why one should never
I just spoke with Derek at IBE, having just taken delivery of two
sets of 2V industrial cells, one for a customer and the other for my
own home. On the customer's set, installed yesterday, I measured one
cell as .01V lower and .022 SG lower, before hooking up to any

HUP Solar One batteries recommend topping off the
electrolyte and doing an initial EQ cycle prior to use. We
always check SG and voltage/cell on arrival and to date
never had any discrepancy on either.
Additionally we unbolt all connections, polish with a copper

First off, there is never a reason to add acid. The acid/water mixture is very
specific and should not be changed.
