Where can I find Instructions for complete simple solar pv setup including indoor wiring? I searched this forum for Simple Solar PV but nada. Is there a good book? I need to run an air conditioner for 160 sf and some lights and exhaust fans for cooking and shower. Probably a small pump for getting water to the shower and sink. What's the appropriate tech for hot water at latitude 35, probably not PV? A little fridge would be nice but I can live without it for now.
My wife and I are in the middle of doing a similar project. Ours is an off grid 400 square foot cabin running an air conditioner, fridge, water pump, exhaust fans and lights. We're planning to do batch solar hot water heater with backup tankless gas water heaters. The wiring is complete and we just hooked up the solar power system a few days and everything seems to be working.
I didn't find any sources that combined indoor wiring and setting up a solar power system. Here are some books I found useful:
General Electricity/Solar Power Concepts Off Grid Power by Chris Haynes
Wiring Wiring Complete by Michael Litchfield
Wiring a House by Rex Cauldwell
Solar Power System Setup Youtube (Will Prowse has some really good videos)
I have a 40' high cube. I built my pv rack out of superstrut(SS) from home Depot. I welded SS 4 hole brackets to the roof channels. I have a midnite mnpv6 combiner mounted inside, 2 breakers for my panels, 1 dc-gfp-63 breaker (ground fault protector) that feeds to a Outback flexmax 80. The Flexmax 80 feeds to a Conext DC switchgear/SW 2024 inverter (24v input, 240v AC output). I then wired to a 100amp AC service panel ($65 Home Depot).
My batteries are LifePo4. All my connections and batteries are inside save for the pv extension connectors on the roof.
Purchased a black iron bolt and nut from Hardware store, welded that to outside bottom channel of container. Purchased a copper lug for bolt for a ground connection. 8' ground rod driven into ground by lug .
Interior is wired with 12/2 , 250feet is $65 @ Home depot
I don't have any fuses or disconnect switches. I can isolate anything in my system with a flip of a breaker.
Edit- I also have a lightning arrestor on my combiner box.
Edit- see if you can find the midnite solar DC-GFP-63 installation instructions online that will show you your PV basic wiring diagram, it does not show the inverter in diagram.

I have 4 Hanwa Q-duo. Each panel is 310w 39v 9.8 amps. Mono panels great low light. 2 panels in series 80v max18 amps Flexmax80 only uses 15amps pushes 30amps to inverter (Flexmax CC's double amperage output) Total 1240w. I end up charged by 9 am, cloudy day it might be 11:30. My system went online 11/2019 have had 0 problems. If you need I can send info and photos by email. I am more than happy to help, I was an industrial mechanic in a past life.
Edit- the pv panels are a German design anti LID panels research showed great low light panels, 12 /25 year panels
Edit- I am section 608 and 609 EPA certified I have universal certification. Updated 410a compliance.
Your best bet is to install a Pioneer split mini for AC 240v running 5 amp per leg.
Aaron, wow $7800 for the system! Can anyone wise in solar suggest how many watts are needed to run a small window AC in a 20' insulated shipping container and how much that system is liable to cost if I can manage to install it myself?
Permies is awesome!!!
