4096Wh, 4000W, and true 120V/240V split-phase output. The DELTA Pro 3 is one of the few portable units that can run a well pump or central AC circuit — here’s the honest Texas verdict.

The DELTA Pro 3 is the portable power station to buy when you specifically need 240V loads — well pumps, central AC circuits, EV-level charging — without committing to a permanently installed standby generator. It is expensive and heavy, but nothing else in the portable class runs the loads that actually keep a rural or suburban Texas home livable through a multi-day outage.
Why 240V is the whole story
Most portable power stations top out at 120V. That is fine for a fridge, fans, lights, and phones — but it cannot run the things that matter most in a serious Texas outage: a well pump (no 240V = no water), a central AC compressor circuit, or an electric range. The DELTA Pro 3’s headline feature is true split-phase 120V/240V at up to 30A. That single capability moves it from "camping luxury" into "actual home backup."
Capacity and runtime, honestly
The base unit holds 4096Wh of LiFePO4. Here is the math that matters: a typical refrigerator pulls ~150W averaged, so the base alone runs it for roughly a full day. Add a 1.5HP well pump cycling a few minutes per hour and you are still comfortably into 24-hour territory. Try to run a 3-ton central AC continuously and you will drain it in a few hours — this is a bridge through an outage and a way to keep critical circuits alive, not an unlimited grid replacement. Stack two expansion batteries (12kWh total) and you can prioritize fridge, well, a window AC, and devices across a 1–2 day event.
Solar and recharge
It accepts up to 2600W of solar. In strong Central/South Texas sun with a proper array you can refill the base in under two hours, which means during a daytime outage the unit can keep topping up while it powers your priority circuits. AC recharge is fast too, so you can opportunistically charge whenever the grid flickers back.
Who it is for
Rural and well-water homeowners, anyone whose outage plan absolutely requires 240V, and preparedness-minded families who also want a unit they can take to a job site or RV. If your needs are just fridge-fans-phones, save thousands and buy a 2000Wh-class unit reviewed elsewhere on this site.
