Help With RV Solar Wiring Diagram

Wiring Diagram: https://ibb.co/fC6Tv9

Hi all, looking for some assistance with a solar setup for an RV! My wiring diagram pictured above.

Questions:

1) Do I need any more fuses/breakers?

2) If I get a 50 amp mppt charger controller, I shouldn't run it and the 75 amp converter/charger at the same time right? From what I've read, the two chargers can't work together and configure voltage accurately (for float etc.). Or if I do, only use the two combined to get the batteries up to 80%. With 800ah battery bank the two combined will only be about 0.17C, but I'm worried about the voltages not being right for float charging.

3) The 2500w inverter is combined with a 75 amp charger/converter with an auto-transfer switch. Does this affect my wiring in any way? I feel like with the way it's set up, it will want to output power to the solar charger? I think this is wrong, but I just wanted to check.

4) Am I missing anything else?

Notes:

  • Wiring is a bit oversized because I want to be able to pull close to 250a for short periods.

  • Panels each do about 27v @ 6.5 amp at NOCT, the 45.5v @ 12v was an equivalent I listed to put it in terms of the battery bank.

Thank you!

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6

PG&E Aggregate Net Metering Application Help

PG&E Aggregate Net Metering Application Help Earlier this year I completed a ground mount at a ranch in Paso Robles, CA. This ranch has two meters, requiring me to complete the PG&E’s Aggregate Net Metering Agreement. 8 months later my application has been rejected multiple times. I’ve spent dozens of hours on the phone with various support services with no solution. I’ve given it my all. Does anyone have any contacts for professionals who I can hire to complete this process for me? Or any tips for completing this process? Honestly, this issue has become the bane of my existence and I need it solved. Any help is greatly appreciated.
