If you're building a bus or large motorhome and want to live comfortably off-grid — this is one of the systems we’ve designed specifically for dependable day-to-day use without going overboard on budget. In the video above, I explain how to size your off-grid setup properly — including how much solar you need, what size inverter makes sense for your lifestyle, how to charge from your alternator, and what kind of battery capacity is enough to get you through the night.

The 48V Large Bus - 3000VA Budget Off-Grid Kit #80 is a cost-effective, solid solution built around the Victron MultiPlus II 3000VA inverter/charger. It provides consistent power for essential appliances like fridges, lights, and a coffee machine, making it ideal for those who want a streamlined off-grid setup with all the basics covered.

This kit includes one Victron SmartSolar MPPT 150/45 solar charger to support up to 2250W of solar input, along with one 5.12kWh BSL lithium battery. It’s perfect for users who want a reliable base system that can be expanded later. The Victron Cerbo GX and 7" touchscreen provide intuitive control and monitoring, both locally and via the Victron VRM app.
