EcoFlow DELTA Pro

3,600 Wh and 3,600 W of AC, on an LFP battery. It has the third-fastest wall charging of the 13 stations in the 2,500 to 4,000 Wh class.

The DELTA Pro in brief

Solar can arrive at up to 150 V on the DELTA Pro, so a long string of panels fits. In series that means as many as 5 of the 160W or 220W portable panels in series, or 3 of the 400W Rigid. Total input is 1,600 W. It stores 3,600 Wh in LFP cells rated for 3,500 cycles to 80 percent, sends out 3,600 W of AC with a 7,200 W surge rating, and weighs 99 lb. Wall charging takes 1.8 hours at 3,000 W, third-fastest of the 13 stations in the 2,500 to 4,000 Wh class. Two Smart Extra Batteries lift the system to 10,800 Wh, and a kit adds split-phase output. The operating range is 14 F to 113 F.

How long the DELTA Pro runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. About 3,060 Wh is usable, so a 104 W refrigerator goes 33 h to 4 days and a 1050 W sump pump 2.9 h to 3.8 h.

Work out your own mix of loads. A red bar means it draws more than the 3,600 W this station can supply.

Solar time assumes panels reach 75% of their rating. Figure it for your state and panels.

Solar panels for the DELTA Pro

Its XT60 port takes 11 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.

EcoFlow's manual does not name this plug, so confirm it with the maker before you buy a cable.

Extra batteries for the DELTA Pro

Who the DELTA Pro suits

Look at the DELTA Pro when you want 3,600 Wh and a long string of panels. At 99 lb it is heavy, and its UPS switchover of 30 ms is slower than the 10 ms listed for the Jackery HomePower 3600 Plus. The Jackery HomePower 3600 Plus is 77.16 lb, with 6,000 cycles to 70 percent and room for 21,504 Wh. The Anker SOLIX F3800 Plus gives 6,000 W of AC, though it weighs 135.6 lb.
