Setup with the Smart Home Panel 2

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.

Sizing the auto-switch to your home

The DELTA Pro Ultra is designed to be placed, not installed. Set it on a level surface, plug it into a wall or a panel, and the onboard brain handles transfer switching and load priority — no electrician required for basic backup.

Most owners start with a plug-and-play setup: fridge, router, and a few lights on the DPU, then grow into a panel tie-in later. That staged approach keeps the first day simple and the upgrade path clear.

Wiring checklist before you flip the switch

Ventilation and clearance are the only real setup rules. Give the DPU room to breathe, keep it off carpet, and you have a safe, indoor-rated power source that a gas generator could never be.

A permanent setup adds a transfer switch and a wall mount, but the unit works identically freestanding. Buy it for the simple day; upgrade it for the serious one.

Why whole-home backup feels different

The DELTA Pro Ultra sits in that rare sweet spot: serious capacity without serious complexity. 6kWh base, expandable to 90kWh and 7,200W continuous (12,000W 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 DPU delivers 4,000+ cycles to 80% of dependable runtime and a 0% to 100% in about 1.3 hours from wall that respects your time.

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.
