FAQ

Can Delta 3 or Delta 3 Plus be stacked and placed? What is the maximum number of identical devices or power packs that can be placed?

Yes, but it is recommended to stack only one power pack because the device only has one XT150 interface. It is recommended to place only one power pack

Does the device support charging with multiple inputs (solar, mains, oil engine, etc.) at the same time, and connect AC, solar, and oil engine inputs at the same time? When the maximum input power is exceeded, which one should be charged first?

Delta 3 or Delta 3 Plus can charge devices through the AC input port, XT60 input port, and XT150 port. It supports connecting multiple input sources simultaneously and has the following charging priorities. EcoFlow Micro Inverter (via XT150 port) > Solar (via XT60 port) > AC power (AC input port, including grid power and generator (Smart Generator 3000 (Dual Fuel))) > EcoFlow Smart Generator (input via XT150 port (DG200, Smart Generator 4000 (Dual Fuel)) > EcoFlow driving fast charging (via XT150 port)

How is the remaining power calculated on the main page of the App when the device is connected to the power pack?

(Total Equipment Capacity * Remaining SOC Percentage + Power Package Capacity * Remaining SOC Percentage)/(Total Equipment Capacity + Power Package Capacity) For example: Delta 3 1500 (1500 Wh) battery 40% connected to Delta 2Max power pack (2048Wh) battery 50%, the display battery is: (1500 * 40% + 2048 * 50%)/(1500 + 2048) = 45.77% ≈ 46%

After the device is connected to the power pack, does it support firmware upgrades for other models of power packs?
