The DELTA 3 Max Plus in brief

Highest AC output of the 19 stations in the 1,500 to 2,500 Wh class: 3,000 W, with a 6,000 W surge rating. That gives the DELTA 3 Max Plus the headroom the plain Max lacks at 2,400 W. It has two XT60i inputs, takes 1,000 W of solar at up to 18 A, and refills from solar in 2.7 hours or from the wall in 1.1 hours at 1,800 W. The 2,048 Wh LFP pack weighs 48.7 lb, and a USB-C port gives 140 W. Up to 4 DELTA 3 Max Plus Smart Extra Batteries, each 2,048 Wh, build the system to 10,240 Wh. The UPS switchover is 10 ms and the warranty is 5 years.

How long the DELTA 3 Max Plus runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. About 1,741 Wh is usable, so a 1500 W microwave runs 1.2 h to 1.7 h and a 45 W Wi-Fi router runs 39 h to 8 days.

Solar panels for the DELTA 3 Max Plus

Its XT60i port takes 11 to 60 V, up to 18 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.

All 2 of its inputs: input 1 XT60i (11 to 60 V, 500 W); input 2 XT60i (11 to 60 V, 500 W).

Extra batteries for the DELTA 3 Max Plus

Who the DELTA 3 Max Plus suits

This is the one for a shop or a house with a well pump (1000 W running, 2100 W startup) next to a fridge, where the 3,000 W ceiling leaves room for both. Skip it if you will never add batteries and want less weight: the DELTA 3 Max is 44.8 lb and 2,400 W. The Jackery HomePower 2000 Plus v2 is 41.45 lb and 2,400 W but expands to 12,288 Wh.
