<div dir="ltr">I just checked out the Homegrid batteries. Just throwing this out there. If there is enough ceiling height you could hang them. That's typically how we deal with transformers in commercial and industrial settings. We usually build a permanent gantry out of square tubing, 1/2" rod and strut. Then ratchet strap or chain hoist them up.

<div>It looks like you have kept the gutter heat gain down to protect electronics. <span style="color:rgb(34,34,34);font-size:16px;font-family:Roboto,sans-serif;font-weight:300;background-color:rgb(255,255,255)"><span> </span>“the rule of thumb is that every 10°C increase in temperature reduces component life by half”</span></div>

<div dir="ltr">Hi Drake,
<div>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.</div>
