What the DELTA 3000 Gen4 actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

From the test desk
“**I'd buy the DELTA 4 (3000) unless your load is still growing.** It holds 3,072 Wh to 2,048 Wh, runs 3,600 W to 2,400 W and is rated for 6,000 cycles to 3,000, for $650 more and 6.6 lb more to lift.”
“**If a blackout is why you're buying, I'd take the DELTA 4 (3000).** It holds 3,072 Wh against the Classic's 1,024 Wh and finishes our eight-hour blackout with 966 Wh left, where the Classic runs out 775 Wh short.”
“**I'd buy the DELTA 4 (3000), unless you'll outgrow 3,072 Wh.** For $500 more it holds 1,024 Wh more, runs 3,600 W against 3,000 W and carries a 6,000-cycle rating against 4,000, at about the same money per watt-hour.”
