Wrenches,
We are primarily a grid-tied solar EPC but like many solar companies have a
long history with small off-grid installations. In the past few years we
have been tackling a handful of large, complex, grid-tied battery-backup
systems (sub 90 kwh) range with some working flawlessly and some
Hi Sam -
It's been probably 6 or 8 years since I've selected a 3rd party automatic
transfer switch, but we used to use Briggs & Stratton products with good
results:

I have a system with Generac ATS where Grid is Primary source, SolArk
Critical Load is secondary source. And whole home is the Load out of the
ATS.
Generator feeds in to the SolArk Gen terminals. KOHLER generator
(2-wire auto start) engages only when the SolArk tells it to, programmed by
me a

August, thank you for the recommendation of the Briggs & Stratton. And in
case others have commentary to add that references the point that you made

We used to work with / recommend ASCO, but no longer. We had a site with dual
ASC8000’s 400A 3 phase units switching between Gen 1 and Gen 2. Control board
sensor problems arose and it failed to auto transfer back from Gen 2-1 due to
sensor issues. Had to get client to open cabinet and affect a
Wrenches,
If you are looking for a very good ATS, you need to look at ASCO that's
what they do, from small less than 100 amp to high voltage multi 1000 amp
units, they are a simple 2 wire start, l also use the Kohler products with
no issues, l have AC Coupled off grid, DC Coupled on grid
Fun times
I recently set up a Generac ATS to transfer to an existing Magnum off
grid system. Grid was added to the house later. I ended up putting a
7ah 12 v battery, 120 vac outlet, and 1 A charger inside the enclosure
to power the ATS. Gird sense was connected right to the grid input
terminals in the
We ran to an install by others that had a Radian 8048 for backup tied to a
Generac auto transfer switch & the 12vdc from the Radian was the 12volt power
source the Generac control card had died & we had to buy another Generac ATS &
gut it to get another controller, they would not sell just the c
I'm gonna add that the ASCO is the way to go. They offer both normal ATS
and with a service entrance rated breaker. I have dozens out there on GTBB
systems. What I really like about them is you can adjust a pot so that
there is little to no time delay in which the home switches over to
battery. Unl
Nice. I’ve considered using a little jump battery once or twice but still
haven’t had to.
I put on my calendar ~3 years replace all gen-start FLA batteries
because the consequences of them going dead are pretty bad. Curious if you
guys think 3 years is a good rule of thumb.

I have had good experience with Kohler transfer switches but only the
simpler RDT models should be used in conjunction with a complex custom
system.
(Kohler’s cheaper RXT models require a keep-alive signal from a Kohler
generator)

Even the industrial Generac ATS's use plastic gears now. They're awful and
parts like the gears, CPU's and sensors have been unobtanium. My preference
has been Eaton first and then Asco.
