The DELTA 3 Max in brief
Solar current is the limit to watch on the DELTA 3 Max. Its XT60i port is capped at 13 A, and EcoFlow warns that going past it damages the unit, which is why the full 500 W of solar takes 5.5 hours to refill 2,048 Wh. The wall is much quicker at 1.1 hours and 1,800 W. Power runs to 2,400 W of AC with a 4,800 W surge rating, fourth-highest among the 19 stations in the 1,500 to 2,500 Wh class. LFP cells are rated for 4,000 cycles to 80 percent, the case weighs 44.8 lb, and the UPS switchover is 10 ms. There is no expansion port. USB-C output reaches 100 W.
How long the DELTA 3 Max runs things
Times use about 85% of the rated capacity, the part left after inverter and battery losses. With 1,741 Wh usable and 2,400 W available, a 1050 W sump pump gets 1.7 h to 2.2 h and a 104 W refrigerator gets 19 h to 50 h.
Work out your own mix of loads. A red bar means it draws more than the 2,400 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 3 Max
Its XT60i port takes 11 to 60 V, up to 13 A and 500 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.

Who the DELTA 3 Max suits
Choose it as a single-box outage kit: fridge, freezer, router and a well pump (1.7 h) with nothing to add later. Anyone who thinks capacity may need to grow should look at the DELTA 3 Max Plus, which has 3,000 W of AC and takes up to 10,240 Wh. The Jackery HomePower 2000 Plus v2 weighs 41.45 lb, is rated 6,000 cycles to 70 percent and expands to 12,288 Wh, though solar input there is 800 W.

FAQ
What is the solar limit on the DELTA 3 Max?
500 W through one XT60i port, between 11 V and 60 V and no more than 13 A. EcoFlow says current over 13 A can damage the unit. Single 400W panels and pairs of 160W or 220W portable panels are inside the voltage window.
Can the DELTA 3 Max be expanded?
No. It is listed as not expandable. The DELTA 3 Max Plus is the version that takes extra batteries.
How long does the DELTA 3 Max take to charge?
1.1 hours from a wall outlet at 1,800 W, 5.5 hours from solar and 21.3 hours from a car's 12 V socket.
Can it run a microwave oven?
Yes. A 1500 W microwave is inside the 2,400 W output and runs 1.2 h to 1.7 h.
