12V Caravan - 3000W Budget Kit #25

Description

If you're building a caravan or camper and want to run everything from your coffee machine to your air conditioner — this is one of the best value 12V systems we’ve designed specifically for dependable day-to-day use, all in one easy DIY-friendly kit.

The 12V 3000W Kit is a powerful system built around the Renogy Pro 12V 3kW Inverter Charger. It includes two 300Ah Renogy Core Mini lithium batteries (600Ah total), sized to run serious off-grid appliances — and paired with a 60A Renogy Rover MPPT controller to handle up to 800W of solar input.

It also includes the Renogy DC50S dual-input DC-DC charger — Landon’s favourite pick for vehicle charging. This compact unit charges the battery bank from your alternator while driving and features a second MPPT input just for portable solar panels — ideal for shaded campsites or adding extra solar on demand.

The system comes with Zero Grid’s full set of wiring diagrams, all DC fusing and protection gear, cables and lugs (cut-to-length by you), and everything you need to get started. No guesswork — just a rock-solid 12V system for full-time living or extended trips in your caravan.
