The DELTA Pro 3 in brief
Its 4,000 rated cycles to 80 percent give the DELTA Pro 3 the second-longest life among the 5 stations at 4,000 Wh and up, and the other specs suit a station meant to run a house. It holds 4,096 Wh, 4,000 W of AC, an 8,000 W surge rating and split-phase output. Solar can reach 2,600 W through an XT60 port that wants 30 V to 150 V at 15 A, so panels are strung in series. Wall charging takes 0.9 hours at 4,800 W. The case weighs 113.54 lb. The switchover is 10 ms and the warranty runs 5 years. Two DELTA Pro 3 Smart Extra Batteries take the system to 12,288 Wh.
How long the DELTA Pro 3 runs things
Times use about 85% of the rated capacity, the part left after inverter and battery losses. About 3,482 Wh is usable, so a 104 W refrigerator goes 38 h to 4 days and a 1050 W sump pump 3.3 h to 4.4 h.
Work out your own mix of loads. A red bar means it draws more than the 4,000 W this station can supply.
How fast it refills
Solar time assumes panels reach 75% of their rating. Figure it for your state and panels.
Solar panels for the DELTA Pro 3
Its XT60 port takes 30 to 150 V, up to 15 A and 1,600 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 XT60 (30 to 150 V, 1,600 W); Low-PV XT60i (11 to 60 V, 1,000 W).

Who the DELTA Pro 3 suits
Pick it for a home where the fridge, sump pump and well pump (3.5 h at 1000 W) share one 4,096 Wh battery. Anyone who wants more capacity per box should look at the DELTA Pro Ultra, with 6,144 Wh and 7,200 W. The Anker SOLIX S5000 weighs 97 lb and is rated 10,000 cycles, with 5,024 Wh and 4,500 W. A car's 12 V socket, at 42.7 hours, is not a realistic way to charge this one.
