I am designing an off-grid solar system for my tool shed.
I have a few power tools:
+ LED lights
I never use more than two tools at the same time, but the compressor might be running for a few hours while I'm working on other things. Usually, I work a few hours every other day.
So far I decided to buy:
2*200Ah 12V batteries from Renogy:

400W 12V off-grid solar kit from Renogy with 2*200W panels:

XYZ INVT 4000 Watt Pure Sine Wave Inverter:

EQ 125 Amp 4-Space 8-Circuit Load Center
https://www.homedepot.com/p/Siemens-EQ-125-Amp-4-Space-8-Circuit-Main-Lug-Surface-Mount-Indoor-Load-Center
2*30A + 1*10A Siemens circuit breakers + GFCI receptacles, LAD lights, 10 AWG wire for receptacles, 14 AWG wire for the lights, 8 AWG wire between the Load Center and the inverter, grounding rod, cerrowire
I have 0 AWG wire to connect the inverter and batteries and 2 AWG to connect the batteries with each other.
I have doubts about the inverter, from my math, it looks like to run 2*15A tools at the same time I need 3600W, but how is it in practice, maybe I will be fine with 3000W Pure sine grom Renogy?
Also, it is very hard to find an inverter with GFCI or one that allows L and G bounding. Since I am using GFCI receptacles I am not so worried about it but it is always nice to have an additional layer of protection.
Unfortunately, price is the issue so I cannot afford a full-blown LFP system at the time, and already everything above costs me more than the materials for building the tool shed itself.
Any advice, suggestions, or criticism is highly appreciated.
