Building the ultimate solar system for totally off-grid cabin using EG4 6000XP inverter. Building this setup the closest to NEC 2020 code as possible in case I later need to ask permission from the local authorities (pay homage). Since there will not be a large demand for power in general, we are not building a very large setup. The three main items: (1) 110v shallow well pump, (2) mini fridge, and (3) Starlink aka Musky. Other misc items: interior lights, exterior lights, and few outlets.

STAGE 1 - Adjustable Solar Mount
Building an adjustable solar mount (thanks - Rodney Hunt for the design). Will have (12) Hyundai 395W Bifacial Solar Panels wired in 2S6P.
Part 1 -
Part 2 -

I will have complete build plans for this setup too! Stay tuned for that...

STAGE 2 - Solar Shed
Building a 6x6 solar shed that will house the EG4 6000XP inverter & (3-6) EG4 LL-S batteries.

STAGE 3 - Wiring to Cabin
Running conduit from solar shed to the cabin

-----------------------

Here are the basic wiring plans... Lots of insight from folks on this forum (thanks) and will be posting this build and make updates as it happens...

Over the winter I installed my 6000xp at my cabin, no PV yet. Runs almost all circuits in cabin: lights and outlets, well pump, mini split, etc. only thing I don’t have on it is the backup electric baseboards, dish washer, water heater, oven. Ground should start thawing soon so getting ready for PV.

If I started from the beginning, I wound probably redo it with an 18kPV simply to use any excess PV to zero out or reduce grid usage using the CTs in main panel. I would also move mini split back to main panel so battery doesn’t take a hit from it but still uses PV to power, if available.

Yeah, looked into the 18k and after doing the math we will never need that much power - ever.

I do like how the 18k has a wiring diagram that's very detailed, which the 6000XP lacks!!! Maybe only thing I found to be very very very disappointing over the 18k. In fact, I am still scratching head over the DC/AC grounding of the 6000XP and EG4 wouldn't provide a basic wiring diagram for this unit - stupid as hell especially since the 18k has a very detailed wiring diagram so they can't play the liability card.
