Chinese battery solutions maker Bluetti has announced its next-generation of whole-home battery backup products, launching the EnergyPro 13K Energy Storage System, or EP13K.
Having launched the EnergyPro 6K back in 2025, and largely replacing the existing EP900 Energy Storage System, the new EP13K product and launch remains aimed at residential and small business users, but with boosts to output power and storage options, and a new design.
The new EP13K adapts slightly more of a portable vs fixed-in-place design, and goes modular as well to scale storage as it’s needed.
At minimum, a home-owner starts with an EP13K, which houses the inverter and battery management system (BMS) and two batteries, each called an EnergyPack 500. This offers 13.2 kW of power output (120V/240V) and 9.6 kWH of storage. The weight of the EP13K itself is 106 Ibs (48kg) and is IP65 / NEMA 4X rated.
Adding another EnergyPack 500 will add 4.8 kWh of storage, with a maximum of four, for 19.2 kWH of total storage. It has a surge capacity of 150 LRA.
It can integrate with users’ existing rooftop solar systems to store excess solar power up to 22 KW through four MPPTs, or be added alongside a new installation to provide backup energy when needed, supporting both DC- and AC-coupled configurations.
Bluetti also offers an optional smart distribution panel, which it calls the AT1, to pair with the EP13K, to connect to grid power, EV chargers, generators, and solar panels, and supports bidirectional EV charging and integration with standby generators.The integrated automatic transfer switch (ATS) and 155A bypass enable uninterrupted switching between grid and stored power.
In terms of smarts, via the Bluetti app, monitoring of real-time data can occur, along with configuring operating modes such as charging during off-peak hours and discharging during peak pricing periods. It also ties in with smart home platforms.
Like with FridgePower, it also introduces a proactive extreme weather alert function, using weather data to automatically prepare the battery ahead of potential outages.

Bluetti’s EnergyPro 13K Energy Storage System is available now via Bluetti’s official store, with a special promotional price starting at $7,919 (a 10% discount) through April 24, and there’s a promotional code BLUETTI8OFF to receive an additional 8% discount to bring that price to $7,285.48.
