[Kristopher Schmid via RE-wrenches]

Looking to replace a damaged module.  Anyone happen to have a Trina 195
black frame on the shelf circa 2017ish?

Please reply off the list.

Thanks,
Kris

Re: [RE-wrenches] Ballasted ground mounts

[Kristopher Schmid via RE-wrenches]

Thanks for the info everyone.  I was examining this option in the hopes
that my local AHJ might consider it a non-permanent structure and,
therefore, exempt from wetland setback rules.  It turns out that they will
not give me an exemption even with no foundation.  Alas, I guess we move
back 40 feet and dust off the chainsaw...

I guess that I should have mentioned that I am looking at an 8kw

[RE-wrenches] SOK Batteries

[Kristopher Schmid via RE-wrenches]

Hello brain trust,

Anyone have experience with SOK lithiums?  Here's my issue.  Client has a
tiny home and bought their system online (I know, run away...).  Whenever
they start a larger load (power tool, hair dryer) it pulls too much current
and causes the BMS to shut down the battery output.  Not necessarily a huge
issue, but I cannot get the app (ABC-BMS) to reset the batteries.  I log in
with the password and it gives me the reset option, but it will not allow
me to click OK.  Hooking up an external battery charger has been my only
successful reset solution.

Any help would be greatly appreciated.

Thanks,
Kris

You could try contacting the Wisconsin program called "solar for good".

Re: [RE-wrenches] Retail price lists

[Kristopher Schmid via RE-wrenches]

I won't disclose my markup, but I can tell you that I stopped showing
itemized prices on my bids years ago for exactly this reason.  The customer
only sees the final bid amount.  If they want to shop around and buy it on
their own, they will have to self install or find another installer.  Just
my $.02

Re: [RE-wrenches] Attaching Array To or Through Ply

[Kristopher Schmid via RE-wrenches]

Very timely post for me, Matt.  Thanks.

I was just asked to bid a roof mount with SIP panels.  My first thought is
to just say no.  I am very hesitant to rely on the pull out strength of
screws in OSB.

I will be watching this thread.

[RE-wrenches] Fire fighters

[Kristopher Schmid via RE-wrenches]

Hi wrenches,

In speaking to local firefighters last year, I had a question that stumped
me.  At night, will the light from the flames or the fire fighters' flood
lights energize the array to a dangerous potential?

Any light you can shed (pun intended) would be most welcome.

[RE-wrenches] Inverter bypass

[Kristopher Schmid via RE-wrenches]

Hi All,

I have a stand alone system that was upgraded from an FX inverter to a
Radian WITHOUT  the companion load center.  I would like to add an inverter
bypass circuit to operate the house on generator power.  There used to be a
4 slot breaker panel (SqD?) with the rocker switch preventing both breakers
from being in the on position simultaneously.  I have not been able to find
it on the interweb.  Anyone know of something out there that would meet my
needs?

Kris

[RE-wrenches] Low voltage lithiums

[Kristopher Schmid via RE-wrenches]

Greetings all,

I have seen an issue on two different systems that I am hoping someone can
shed some light on for me.  One was a 48 volt pack of 12 volt Battle Bornes
and the other was a 24 volt pack of SOKs.  What happens is when reaching
the end of the bulk charging stage, the battery voltage spikes and sends
the inverter into an overvoltage error.  Can anyone explain what is
happening and a solution?

Thanks,
Kris

[RE-wrenches] Head scratcher

[Kristopher Schmid via RE-wrenches]

Hi All,

I am hoping that someone on the list can help me think this one through.

I have a client that builds tiny portable homes.  He is working on one
where his client supplied the solar modules, charge controller, batteries,
inverter, etc.  They bought them through some dot com.  The tiny home has a
240 volt mini split that they want to use when plugged into the grid.  The
inverter that they bought is a 120 volt.  The inverter is not grid tied,
but does have a 120 volt grid input for battery charging / pass thru.

So, my issue is, how can I make this work?  I am thinking of using a 50 amp
automatic transfer switch like a Surge-Guard-40100 and connecting the solar
inverter as primary and grid as backup but am not sure if that unit will
disconnect the grid with only one leg energized.   Physical space for
components is very limited

If anyone has some ideas here, I would sure appreciate it.
(other than "just walk away" or buy a 240 volt inverter)

Thanks,
Kris

[RE-wrenches] Qualifying equipment

[Kristopher Schmid via RE-wrenches]

Has anyone ever heard this from a tax advisor?

Am I missing something?

What our account said is, if we were audited, the dept. federal revenue
would ask for a certificate from the manufacturer of the solar equipment
showing that they qualify for the credit. He said not all manufacturers
qualify. If you are certain that it qualifies, you could get the
certificate from them for us.

[RE-wrenches] Hail

[Kristopher Schmid via RE-wrenches]

We had a pretty serious weather event and one of my clients had hail broken
glass.  I advised him to request a replacement of the whole array or, if
not, a module by module inspection for I-V curves and hot spots.  I am
wondering if should reach out to other clients.  I don't want to be a storm
chaser, but am concerned about micro-fractures.

Waddayallthink?
