In this article, seasoned DIYer Peter Flynn walks readers through every phase of transforming a 1989 MCI 96A3 coach, nicknamed "the Elephant", into an off‐grid solar powerhouse.

The build centers on a 24-volt system featuring 1,500W of rooftop photovoltaic panels, a robust 600 Ah LiFePO₄ battery bank, and an Electrodacus SBMS0 battery management unit. Flynn dives beyond just gear selection; he shares his process for performing an energy audit, designing battery configurations, selecting wiring layouts, and sourcing cells, all aimed at reliably powering essentials from a fridge and microwave to air conditioning and power tools without resorting to shore power or generators.

Rich with wiring diagrams, real-world lessons, and reflections on balancing DIY ambition with safety and efficiency, the article is a practical roadmap for anyone looking to build a serious boondocking solar system in a full-size bus.

A little update on this article.

This System as designed in the article has run flawlessly since it was turned on.

I just acquired 2 more used 250 watt solar panels of the same type as the others, once installed this will bring the total solar array up to 2000 watts.

I have also acquired a Victron Multiplus 48 volt, 3000 watt inverter, this will allow me to do some load assist between the batteries and shore power.

The Multiplus is also completely controllable by the Electrodacus without any modifications.

I will do an update after I have done the install.

Meant to say, Victron Multiplus 24 volt, 3000 watt inverter. (not 48 volt)
