Hey Guys you do have some great points.Here are my comments.
*Taking Readings while EQ'ing. *
Yes, this is not fun, and one of the big reasons I'm not a big fan of
EQ'ing at all. As a matter of fact, I tell people all the time if you
properly charge your battery bank on a regular basis,
Jay,
That was probably me. I did try it again (on camera again) and it started
the compressor 3 times in a row. There could have been an unbalanced load
on 1 leg, but I'm not sure. Sol-Ark says they've mostly fixed this issue,
so I'll be doing a firmware update and trying the test again. I'll
My recommendation on the HUPS that I install are:
Use a refractometer!
Check your SG, & compare all cells & if highest to lowest – If 0.02 or less no
need to EQ.
If 0.04 or greater time to EQ.
I water every 8 weeks with a pump watering system, winter about
Good morning everyone.
The reason you don't fill to full before you EQ is you want to prevent
water loss due to pressure.During the EQ process, there is lots of
gassing and pressure, part of the reason you should loosen the 1/4 bayonet
caps on the tops of the battery If the water level is
Yes that has happened with 2 of mine Jerry. I like the Transformer
Devils that I know. Might check these out in 2 or 3 years. The whole all in
one does not really appeal to me either but I will keep an open mind, in 2
or 3 years!

don't"
A main point to the choir is that each manufacturer has their own
recommendations. The US battery I often use has monthly EQ.
Looking at 30
years of batteries here and the Offgrid manufactures seem to change what
they like over time. Sometimes it is so complicated that I can't expect my

Thanks for the replies. I am going to assume Howie is not eating his
batteries during any point of the recharge process.
A few respondents are not aware of constraints against watering batteries
prior to charging. Here is a typical passage from a battery O manual,
below. This is
Dave makes a good point; I also don't recommend opening the cells while
they are charging at a high rate. I like to get SG readings with the
electrolyte being mixed by bubbling, but I turn off the charging
sources, and let it settle down for a few minutes, before opening caps.
And I second
It is also interesting how sol ark sells over the counter to end users and
also through distributors but at nearly the same price so it makes it
difficult for our distributors to carry the sol ark products.

We have been successful with double and triple Sol-Arks being able to start
just about any single phase loads, the imbalance tolerance is multiplied per
inverter.
Like others we had numerous single inverter sites having issues offgrid,
primarily while completing construction, chop saws and
Is anyone aware if this is alleviated with a parallel connected pair of
inverters? I'm not saying that is the right solution, but it might not
matter in a larger parallel connected system.

That does not sound best to me. I get the point but there are much better
ways. Not good for you to be close around a bank in EQ. If you are checking
water level every month the level should not be really low. You do this in
case you miss a cell a month back! You should be counting as the water

I think the instructions to "not add water before EQing" are just that
the fluid levels will rise as the batteries come to full charge, so you
don't want to end up with over filled cells. I would advise to just
fill all the cells to at least a 1/4 to 1/2" over the moss plates, but
to be a

I saw a you tube video from what appears to be a pretty well versed installer
who mentioned that sol ark knows this is an issue and specifically mentioned
that his small air compressor will shut his 12kw inverter
Hi william
My experience shows me that first filling with water to normal full mark and
then eq provides the best results
Many years ago I had my own battery bank that needed an eq. Newer batteries
well maintained They were low on water but within the normal range. After 2
eq the sg were
My Rolls manual says:
"It is recommended to water the battery cells half way through the
equalization. This is to
assure the water is completely mixed into the electrolyte."

William,
It certainly is possible I've missed something, but I've never seen any
references to not eating batteries before equalizing. If anything, there is
statements saying make sure to check levels before equalizing. I'm not sure
why you wouldn't bring levels up before equalizing...
