BLUETTI EP900+B500 Home Battery Backup

BLUETTI EP900+B500 Home Battery Backup is one of the most advanced complete solar power kits for homes available today. With an expandable 10–20kWh battery capacity and up to 9,000W of continuous output, this system is engineered to power everything from daily household appliances to essential backup during extended outages. Whether you need a solar generator kit for homes, a reliable solar power generator for camping, or a system that can fully support an off-grid lifestyle, the EP900 offers unmatched flexibility and strength.

Designed to seamlessly integrate with new or existing solar systems, the EP900 stores your extra solar energy and makes it available at night, during peak utility pricing, or in the event of a solar storm power outage. This ensures energy independence, lower electricity bills, and the peace of mind of knowing your home will stay powered, no matter the conditions.

Unlike many systems that only provide one type of output, the EP900 is built with dual 120V and 240V voltage capabilities, making it powerful enough to run large appliances such as HVAC units, refrigerators, washers, dryers, and power tools—all from a single unit.

Its LiFePO₄ battery chemistry provides industry-leading safety and longevity with thousands of life cycles, while the BLUETTI smart app allows you to monitor and control your energy usage in real time.

The EP900 isn’t just a battery—it’s a complete solar generator kit designed to deliver whole-home energy resilience.

Why Choose the BLUETTI EP900+B500

Massive Energy Storage
From 10kWh up to 20kWh, this system ensures you can store enough energy to power your home during extended outages or periods of high demand.

Whole-Home Power Coverage
With 9,000W continuous output and both 120V and 240V options, the EP900 can run small electronics, essential appliances, and large household systems—making it one of the few solar generators that can power a house.

Peak Load Shifting for Savings
Charge your system with free solar power or low-cost off-peak grid energy, then discharge during peak hours to save significantly on utility bills.

Sell Energy Back to the Grid
Turn excess solar energy into income by feeding unused power back to your utility provider.

Reliable LiFePO₄ Safety
Built with advanced lithium iron phosphate chemistry, the EP900 is safer, longer lasting, and more environmentally friendly than traditional NMC batteries.
