Re: [RE-wrenches] Programmable battery chargers

[Andrew Perkins]

Yeah we used to be able to open up the IOTAs and do that now they are all 
riveted shut! I was using Powermax for a long while but they kept failing on us 
so I went back to iota. I am selling those Rolls S6 series L16s and they need 
to be charged at a higher voltage but none of the standard presets will go that 
high. Maybe ill give them another shot.



Thanks for the reminder.

Andrew,

We open the Iota DLS series and adjust the output voltage for our needs. Have 
done that for many years. The dual voltage jack can then be used for 0.6 Volts 
switching. We have also used relays and external voltage controllers to 
automate the DLS voltage switching when the IQ module is insufficient.  



Also look at the Powermax PM series. They have a voltage adjustment but don’t 
have the dual voltage that DLS offers.

Scot,
We have used Prism Solar for glass on glass pergolas. Not sure if the price
is any better than Lumos. Im not totally in love with the custom racking

[RE-wrenches] looking for a glass-on-glass, frameless module; bifacial preferred but not essential

[scot.arey]

Good day, wrenches:

 

Seeking any insight on a module that fits my needs.

 

We used to use Sunpreme glass on glass frameless but they went under with
little fanfare (and after winning a significant manufacturing award kind of
like Solyndra but smaller.).

 

We use there on our solar pergolas. WE have used framed modules but it just
looks horrible.

 

Does anybody know of anyone but Lumos is making this product (their LSX is
frameless)? Lumos is beautiful but hard to make work in low-electricity cost
Texas.

 

Thanks,

Thanks a bunch Jeff,

I was on Wrenches from 2000-2010 but then when I left the business of my 
previous employer working for Jon Hill at Sierra Solar Systems I never took the 
time to rejoin. I thought I had changed my email a couple times but apparently 
not successfully. Too much time out in the field but never stopped thinking 
about all of you!

Thanks a bunch for letting me know about the RPS solution. After I had posted 
that inquiry last week I did do a little more searching but definitely seems 
like a lot of them either have range issues or cost hurdles. Heading back to 
the site this week to confirm line of site for the RPS solution. Still waiting 
on a call back from them about pricing.

Happy 2021, Nick

I don't have direct experience with this wireless sensor but it looks solid:

A google search reveals some others that look less expensive so take a look.

Greetings Wrenches,

I’ve mostly been trying to get away from pumping systems but decided to take on 
a small solar direct Grundfos system for a friend’s mother that lives on my 
road. The well and ideal spot for the array sits about 1000’ away from the 
tanks and it’s the typical scenario of switching over an existing setup where 
all the plumbing lines have been buried for many years so there is no 
opportunity to bury a conduit or cable for the float switch conductors. I’m 
aware of the reverse action pressure switch strategy but do not want to 
pressure the fill lines for multiple reasons. Also, the existing float switch 
wires do not run all the way to the well head either even if I did want to 
rework those and invert the logic with another relay elsewhere. For obvious 
reasons I can’t reassign the old power conductors to the pump either since I 
need to keep those in place to use with the IO101 as backup.

I’ve installed many dozens of these systems over the years and have always 
found a way around it but this job really begs for some sort of wireless 
solution. I’ve been off the Wrenches list for 10 years now so there are many 
threads I’ve not seen and figured maybe the group has come up with a solution 
strategy for these scenarios by now? Obviously the age of Wifi, Bluetooth etc 
has brought us many wireless solutions that did not exist years ago so I’m 
hopeful we now have an answer to these headaches? Even if I needed to add a 
small battery system to power it.

Also just want to say how much I appreciate this list. I rejoined a few weeks 
ago after 10 years off of it and it is so great to see all the familiar 
technicians here. Thank you to Michael and all of you, new and old, for being 
part of the good fight to strive for quality and integrity in this passion we 
all share. The planet needs us more than ever and I feel fortunate for every 
one of you. This list is an incredible resource!

Hope all of you have a great last few hours of 2020 and a prosperous 2021!

Re: [RE-wrenches] Growatt 5k inverter w/ transformer, more China junk?

[Dave Angelini Offgrid Solar]

We want to see the certificate of compliance for UL and all the good
paperwork for power system electronics, especially offgrid. 

Most in the
Sierra can't get fire insurance so we build even better redundant systems
with that in mind. I do not care so much where the equipmens origin is as
much as the company behind it. I like it when a company diversifies it's
manufacturing to many countries.  

This plays really well right now in the
times of C19 and supply lines being strained. Trying also to keep an open
mind about the Chinese government. Weird how certain items have back-logs
also these days.

Re: [RE-wrenches] Growatt 5k inverter w/ transformer, more China junk?

[Chris Mason]

The Growatt inverters are top quality, they ship a huge amount of
inverters. They make US models in split phase. What happened here is the
client ordered something he knew nothing about from a vendor that also
knew nothing. I run into this all the time. That's what we get the big
bucks for.
We buy a lot of chinese inverters for different islands. If we want 230V 2
wire to suit the island, that's what we order. In some cases we order 120V,
some are 240V split phase, and some are 230V.
If it's off-grid, will there be a requirement for UL listing? I would not
worry about the quality of the inverter, they are excellent. I would worry
about the design. If you are not confident, walk away. You will be expected
to make it work or keep trying, and the damage to your reputation if it all
fails will be hard to counter. The client is never wrong.
