Our take
This is the unit that lets a van build skip the traditional lithium-battery + inverter + charge controller install entirely — it's effectively a self-contained power system that bolts in under a bench.
Why we like it
- Fast solar or AC recharge, so you're rarely waiting around
- Expandable capacity as your build (or budget) grows
- Runs a compressor fridge, induction hob and laptop comfortably
