Very nice Install Michael! Was that the project on the xxCloud River we
talked about?
It looks like you have kept the gutter heat gain down to protect
electronics. "the rule of thumb is that every 10°C increase in
temperature reduces component life by half"

Hi Drake,
Those are single phase combiner panels. I would have loved to set this
up as a three phase system, but there was already a mile of underground
single phase run throughout the property. We ended up running a half
mile 15KV line from the power site to the estate. This is an aside,
it's kind of hard to see, but for seperation, we attached the pv
circuits to the back of the gutter using through bolted adhesive backed
cable tie holders. Often we use gutter dividers. They originate in the
tall cabinet at the end which houses controls, secondary PV
disconnects, AC and DC egauges, Tigo hub, Battery hub and (Lynk II). On
the opposite end is a similar cabinet for the collection and
distribution of AC circuits. Also, above and below the batteries are
small gutters for communications and CT wires that run from the
transfer switches to eguage. One transfer switch to alternate usage
(alternating relay) or bypass between Gen 1 and Gen 2, and the other
switch to select inverter or generator power, locally or remotely. In
the AC cabinet there is a 400a contactor and time delay relay to
achieve a generator cooldown as the janky Sol-Arks don't do that and
it's hell on new diesels not to have that function.
