Home Battery System GuideBLUETTI targets both portable and whole home backup. The EP900 is its modular home Energy Storage System. It pairs a high output inverter with stackable LFP battery packs.
Capacity and Power Output
BLUETTI lists a maximum capacity of 19.8 kWh for the EP900 system. The design is modular, so capacity scales with the number of battery packs installed.
The EP900 delivers 9 kW of continuous output power. BLUETTI lists the same 9,000W figure for input, which supports fast recharge from solar and grid.
The system uses a Lithium Iron Phosphate (LFP) battery pack managed by an intelligent Battery Management System. LFP chemistry favors thermal stability and long cycle life for home use.
Efficiency and Warranty
EnergySage lists an efficiency of 85% for the EP900 system. Efficiency figures depend on how the manufacturer measures conversion losses.
The EP900 carries a 10 year warranty. The warranty term pairs with LFP chemistry that is rated for long service life.
