Description
Build a serious off-grid or whole-home energy storage system from the ground up with the EcoFlow 4kWh Power Kits — a complete, modular 48V energy solution engineered for permanent installation in homes, cabins, RVs, vans, and off-grid structures. At 4kWh of LiFePO4 capacity, this kit provides a substantial energy reserve for daily living, overnight battery backup, and solar self-consumption — and the modular design means it’s easy to expand as your energy needs grow.
EcoFlow Power Kits are built around the EcoFlow Power Hub, which serves as the central energy management controller — intelligently coordinating energy flow between solar panels, grid or generator input, battery storage, and both AC and DC loads. The 48V architecture minimizes resistive losses in high-current applications, making it more efficient than 12V alternatives for large installations. The 4kWh LFP battery delivers over 3,500 charge cycles — more than a decade of daily use — with the superior thermal safety and stability that LFP chemistry is known for.
The system supports solar input for renewable energy integration, generator charging for backup, and grid charging to top up during off-peak rate hours. A dedicated DC distribution bus enables the efficient powering of 12V and 24V loads directly from the battery — ideal for van builds and off-grid cabins where DC loads are common. The EcoFlow Power Kits Console (sold separately) provides a permanent, hardware-mounted display for real-time system monitoring without a smartphone.
Expandable with additional LFP battery modules for more storage. Professional installation strongly recommended. Backed by EcoFlow’s standard product warranty.
