Our Books
No Inverter Needed: The Complete 48V Off-Grid DC Wiring Guide — our 26-chapter guide to wiring a home around a central 48V DC bus: point-of-use step-down, DC-native heat pumps, cooking and refrigeration, breakers, fusing and grounding, and where a single inverter still fits. Available in paperback and Kindle.
DC-Direct Off-Grid Equipment (Full Battery)
Everything below runs directly off a 48V, 24V, or 12V DC battery bank — no inverter required. These are real products from Full Battery, a supplier we’ve researched in depth while writing our books and site content on off-grid DC systems.

Whether you’re on a well or catching rainwater off a metal roof, a point-of-use reverse osmosis system at the kitchen sink is one of the simplest ways to get consistently clean drinking water without running a whole-house system off a generator or inverter.
American Made Reverse Osmosis System
A 5-stage under-sink RO system (sediment, dual carbon, RO membrane, post-carbon polish) that runs on normal household water pressure alone — no electricity or booster pump required, which makes it a good fit for an off-grid or well/cistern setup. Includes a 4.5-gallon storage tank, five filter cartridges, a TDS meter and installation accessories.
- 100 GPD membrane, 5-stage (6-stage alkaline version available)
- No electricity or pump needed — runs on household water pressure
- 4.5-gallon storage tank with 5-year warranty
- From $586.55

Note: well water with heavy iron, sulfur or high turbidity, or rainwater with significant sediment, may need additional pre-treatment before an RO membrane — get your water tested and ask US Water Systems about their well water combo systems if you’re not sure your water qualifies.
