Ka'a Nui - Mana (solar power and house batteries charging)

Image
Ka'a Nui Solar power Ka'a Nui has about 700 watts of 12-volt power on the roof.  How best to use and implement is what this blog will be about. Six panels of three different types make up the 700 watts, 2-50 watts at the rear of the van, 2- 100 watts at the front and I think 2- 190 watts panels in the center of the van roof.  . Issues to consider... Can I install and ship lithium batteries?  Not sure yet, having reached out to both Pasha and Matson, it is hard to tell what our options are.

Sooo, why buy a van.  The current concept is to fix and build it out into a sleeper van to include a bed, toilet, sink, fridge and other amenities and ship it to the mainland in a few years when done. June 22, 2024 Progress happens, finally got a weekend of sunny weather to work on solar.  Cut three holes, added grommets to protect the wires, and cleaned up the solar wiring.  Now bringing 8awg line into ...
