The DELTA 3 Ultra Plus in brief

Built for a big array, the Ultra Plus takes 1,600 W of solar at 11 V to 60 V and 18 A, enough to fill 3,072 Wh in 2.6 hours. The wall plug takes 1.7 hours at 1,800 W, fourth-fastest of the 13 stations in the 2,500 to 4,000 Wh class. AC output is 3,600 W with a 7,200 W surge rating, the case weighs 74.3 lb, and the cells are LFP rated for 4,000 cycles to 80 percent. A USB-C port reaches 140 W. It accepts one DELTA 3 Smart Extra Battery of 1,024 Wh, switches over in 10 ms and carries a 5-year warranty. Its operating range is 14 F to 113 F.

How long the DELTA 3 Ultra Plus runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. Of the 2,611 Wh usable, a 104 W refrigerator lasts 28 h to 3 days and a 1500 W microwave runs 1.7 h to 2.6 h.

Solar panels for the DELTA 3 Ultra Plus

Its solar port takes 11 to 60 V, up to 18 A and 800 W. A panel's voltage rises in the cold, so the marks below show each one at 14 F, and a pass here keeps 10% of headroom under the maximum.

All 2 of its inputs: input 1 (11 to 60 V, 800 W); input 2 (11 to 60 V, 800 W).

The Jackery HomePower 3000 is 59.52 lb with the same 3,600 W and 3,072 Wh, though it takes only 1,000 W of solar.

Can the DELTA 3 Ultra Plus be expanded?

Yes, with one DELTA 3 Smart Extra Battery of 1,024 Wh.

How long does it take to charge?

1.7 hours from a wall outlet at 1,800 W, 2.6 hours from solar at full input and 32 hours from a car's 12 V socket.

Can it run a sump pump?

A 1050 W sump pump is well inside the 3,600 W output and runs 2.5 h to 3.3 h. Its 2150 W startup draw is under the 7,200 W surge rating.
