Great build and very similar to my off grid office. Tuff sheds are unbeatable for the price. I went with a 16' x 12' (max size without needing a permit). Spray foamed the interior. Have not needed AC, but planning on putting in a 9k BTU mini split for heating/cooling. I have a 3.3kWh 12v battery for accessories (lighting, water pump, fridge, cameras, 5G/wifi) and a 5.6kWh 48v for the rest. I bought 5kw of used panels but have not mounted them (right now only 1.25kw hooked up laying on the ground) Future plans are to try solar hot water storage - either insulated vacuum tubes, or dumping excess solar -> heating element.
