Makes sense. There's a dude on youtube that has a business installing solar and he generally always uses solark and I think he stated he...

This actually isn't a bad idea. I'm planning on running 2 parallel 10kW AIO's, and had planned on combining it all with PDB's. But in...

I think if one goes this route, it would be best to have a separate panel for combining. If off grid or using a transfer switch like I...

Why would you not just combine into a PDB, with a breaker on each inverter between the PDB? Using multiple backfed breakers seems like a...

Exactly how I’d do it, and how I plan to do it using the Growatt AIO that’s coming out soon.

The same dual power source issue happens for any string inverter with a AC and DC input. Why single out the heat pump for special handling?

Reading the Intro slides, they show 3 battery types (all of Growatt origin); the ALP, Hope and AXE battery. Only one (the AXE) have I...

Easy to throw stones when you're a retailer. Especially when you don't carry stuff of the companies your throwing shade to. Is it...

834 posts about a product that isn't even available, yet. How much more can we say about it? lol

So mentioning the 'much' lower price of some other cheaper Chinese AIO's is not causing Midnite to consider lowing their price?? I was...

Why not just wait until one of the US suppliers has the thing? I’m just not sure it’s worth taking the risk on alibaba

I understand the voltage drop. It's more of the derating for being in a conduit with more than 3 conductors and any potential...

Yeah, it would be easier to just run them all as single string 10AWG. But I'm hopefully future-proofing myself by combining 2 strings...

~350 volts or so. Growatt inverter, SPH 10000TL-HU-US.

Because the inverter MPPT's don't support that kind of amperage. Each inverter has 3 MPPTs, each capable of 22A at most.

Exactly. Thats why I was planning on maybe going a size higher that I absolutely have to. My biggest question is just simply AL vs CU...

Most of us run a heavier gauge of wire for the PV connections than required by NEC simply to reduce the power loss.

Then educate me on why I’m wrong? I understand the voltage drop concept, I also understand derating is required by the NEC

It's not a minimum voltage drop required issue. It's more of an issue with derating in said conduit, and then cost. Why spend $0.60+/ft...

Working on buying wire to run from my ground mounted array to the house where the inverter is going to be located. It's going to be...
