The DELTA Pro Ultra in brief

A 1050 W sump pump gets 5 h to 6.5 h and a refrigerator 57 h to 6 days out of the same 6,144 Wh. The DELTA Pro Ultra is built around a high-voltage solar input: MC4 ports accepting 80 V to 450 V at 15 A and up to 5,600 W, which fills the battery in 1.5 hours. Panels plug straight in with MC4 connectors, and as many as 6 of most listed 160W to 400W panels can sit in series. AC output is 7,200 W with a 10,800 W surge rating and split-phase. The wall refill takes 0.9 hours at 7,200 W, the switchover is 20 ms, and extra batteries stretch the system to 30,720 Wh.

How long the DELTA Pro Ultra runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. With 5,222 Wh usable and 7,200 W of AC, a 1500 W microwave runs 3.5 h to 5.2 h and a 45 W Wi-Fi router lasts 5 days to 25 days.

Solar panels for the DELTA Pro Ultra

Its MC4 port takes 80 to 450 V, up to 15 A and 4,000 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: High-PV MC4 (80 to 450 V, 4,000 W); Low-PV MC4 (30 to 150 V, 1,600 W).

Extra batteries for the DELTA Pro Ultra

Who the DELTA Pro Ultra suits

It fits a house or shop that needs 7,200 W and has the roof for a long panel string; a single 400W panel does not reach the 80 V minimum on its own. The smaller DELTA Pro 3 offers 4,096 Wh and 4,000 W with a 30 V to 150 V window, which is easier on a small array. If you want more of everything, the DELTA Pro Ultra X goes to 12,288 Wh and 12,000 W. The Jackery Explorer 5000 Plus, at 134.5 lb, has 5,040 Wh and the same 7,200 W.
