What 240V unlocks for your home

The DELTA Pro sits in that rare sweet spot: serious capacity without serious complexity. 3.6kWh base, expandable to 25kWh and 3,600W continuous (7,200W surge) cover the loads most households actually lose sleep over.

Whether you are prepping for storms, building an off-grid corner, or just want a quiet safety net, the DP delivers 3,500+ cycles of dependable runtime and a full charge in about 1.9 hours that respects your time.

Wiring the double-voltage setup

Getting the DELTA Pro 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 DP, at least 10 cm of ventilation on each side, and a solar plan if you want the 3.6kWh base, expandable to 25kWh system to recharge through a multi-day outage. Ten minutes of prep now beats three hours of panic later.

Running well pumps and dryers

Backup power is only as good as the day you need it, and the DELTA Pro is built for that day — not the showroom. 3.6kWh base, expandable to 25kWh and 3,600W continuous (7,200W surge) translate directly into “the fridge stayed cold” and “the Wi-Fi never blinked.”

The DP earns its place by being boring in the best way: it sits, it charges, it delivers. No drama, no maintenance theater, just power when the grid forgets its job.

When 120V is enough

From a blackout to a backyard movie, the DELTA Pro is the default power source once you own it. 3.6kWh base, expandable to 25kWh is enough that “should we bring the generator?” becomes “grab the DP.”

The 3,500+ cycles rating means the DP is a long-term household member, not a single-storm purchase. Buy it once, lean on it for years.

Frequently Asked Questions

How long does the DELTA Pro last on a full charge?
Runtime depends on load, but with 3.6kWh base, expandable to 25kWh and 3,500+ cycles, 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 DP with solar?
Yes. The unit accepts up to 1,600W solar input, so you can chain panels and keep it topped up during extended outages or off-grid trips.

Is the DELTA Pro 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.
