Neither is better for everyone; it depends on whether you want the higher rated output or IP66 and Home Assistant.\n\nBattery and solar input\n\nAnker lists a LiFePO4 battery, 5,024 Wh, and a single-device rated power of 2,500 W. EcoFlow lists 5,024 Wh. EcoFlow says the cells are lithium iron phosphate (LiFePO4). Both list 5,000 W of PV input, four MPPTs, and 1,250 W per tracker. Both list a maximum PV voltage of 60 V. Anker also lists an MPPT operating range of 16 to 50 V.\n\nOn-grid and off-grid output\n\nAnker lists on-grid AC output settings of 600 W, 790 W, 800 W, and 2,500 W, and off-grid output of 2,500 W. AC charge power is 2,500 W. EcoFlow lists grid-tied output of 800 W/3,000 W, off-grid output of 3,000 W, AC charging input of 3,000 W, and a maximum charge into the main-unit battery of 2,500 W.\n\nCycles, warranty, weather, and weight\n\nAnker lists 10,000 cycles. Anker lists a 10-year warranty and a 15-year product lifespan. It does not give a capacity-retention percentage next to the cycle count. EcoFlow lists 10,000 cycles and a 10-year warranty. EcoFlow says that cycle life is to 60% retention. Anker lists IP66 and 50 kg. EcoFlow lists IP65 and 45.4 kg. EcoFlow also says 45.4 kg, plus or minus 0.5 kg, for the bare unit.\n\nExpansion\n\nAnker says the main unit is 5,024 Wh and can take five BP5000 expansion batteries, up to 30 kWh total. EcoFlow says one host can stack up to two expansion batteries, to 15 kWh, and a system can include up to six hosts, to 90 kWh. Those are the ceilings each company states. They are different ecosystems, so a pack from one does not fit the other.\n\nHome Assistant\n\nAnker's official Home Assistant README lists the Solarbank 4 E5000 Pro for every firmware version it covers, using local Modbus TCP.\n\nWho should buy which\n\nChoose the STREAM 5000 if the stated 3,000 W on-grid and off-grid ceiling, and the 45.4 kg weight, are what you are buying for.\n\nChoose the Solarbank 4 Pro if IP66 and the Home Assistant integration matter more than the output gap, and 2,500 W on-grid is enough.\n\nCheck your local rules and your utility before feeding power back to the grid.","quickAnswer":{"tldr":"Choose the EcoFlow STREAM 5000 if you want the higher rated output: up to 3,000 W on-grid and off-grid, at 45.4 kg.
