Powering an RV without a generator

RV and camper life lives or dies on power discipline, and the DELTA Pro Ultra removes the guesswork. 6kWh base, expandable to 90kWh covers overnight climate control, a 12V fridge, and device charging without idling a generator at the site.

The DPU recharges from shore power, solar, or the alternator, so you arrive at each camp with a full tank of electrons. Pair it with a foldable panel and you stay out a week longer.

Solar on the road

The DELTA Pro Ultra is built to drink sunlight. With up to 5,600W solar input, you can chain panels on the roof, in the yard, or folded beside a tent and watch the DPU refill while the grid stays down.

Self-consumption is the quiet win: run your home on stored solar by day, top up from panels, and lean on the battery at night. The 6kWh base, expandable to 90kWh gives you the buffer to skip peak utility rates.

   

30-amp and 50-amp considerations

Charging speed is where the DELTA Pro Ultra earns its keep. 0% to 100% in about 1.3 hours from wall, so a mid-day top-up between storms is realistic, not theoretical.

The fast-charge architecture also plays well with solar and your car. Plug the DPU into whatever is handy — wall, panel, or 12V — and it negotiates the safest, fastest draw automatically.

Why owners switch from gas

Getting the DELTA Pro Ultra job-ready is mostly planning, not wiring. It arrives as a self-contained inverter and battery stack, so you can stage it in a garage or utility room and run it off a standard grounded outlet before any permanent hookup.

Before you flip the switch, lock down three things: a dedicated circuit or grounded wall outlet for the DPU, at least 10 cm of ventilation on each side, and a solar plan if you want the 6kWh base, expandable to 90kWh system to recharge through a multi-day outage. Ten minutes of prep now beats three hours of panic later.

Frequently Asked Questions

How long does the DELTA Pro Ultra last on a full charge?
Runtime depends on load, but with 6kWh base, expandable to 90kWh and 4,000+ cycles to 80%, most households get a full night of essentials (fridge, Wi-Fi, lights, phone charging) from a single charge, and far more when paired with solar.

Can I recharge the DPU with solar?
Yes. The unit accepts up to 5,600W solar input, so you can chain panels and keep it topped up during extended outages or off-grid trips.

Is the DELTA Pro Ultra safe to keep indoors?
It uses stable LiFePO4 chemistry and runs silent with no fumes, so it is safe inside a garage, utility room, or RV — unlike a gas generator, which must stay outdoors.
