Stackable Energy Storage System

Stackable Energy Storage System Description
Our stackable LiFePO4 energy storage system is designed for the customers who require a high-capacity, reliable, and flexible energy storage system for their homes or businesses.
The battery system can stack up from 1-4 units of 5KWH batteries in parallel to get max 20KWH.
The stackable storage system is with a built-in BMS for safety and longevity, and also its modular design ensures easy installation and maintenance.
So whether you are a homeowner looking to store excess solar energy or a business seeking to reduce energy costs, our stackable LiFePO4 batteries provide a cost-effective and efficient energy storage solution for you.
- Modular Design: The system is designed to be modular, Plug and Play, allowing for easy stacking of 1-4 modules, providing up to 20kWh of energy to meet the varying needs of different customers.
- High-performance LifePO4 Battery: We use high-quality, first-tier lithium iron batteries that can withstand up to 6,000 cycles, providing safer and more stable power for uninterrupted operation and longer lifespan, ultimately leading to cost savings.
- Built-in MPPT Solar Inverter: The system comes with a built-in MPPT solar inverter, which provides a more streamlined and efficient solution. Customers do not need to purchase a separate inverter, avoiding potential compatibility issues with the BMS.
- Multi-voltage output: The system can output both AC220V and AC110V, meeting the diverse needs of customers around the world.
- Certificate: UN38.3,MSDS,EN55032,EN55024,EN61000-3-2,EN61000-3-3

How Stackable Energy Storage Systems Work
With Only Mains Power but No Solar

When the main power is ON, it charges the lithium storage battery and supplies power to the load at the same time.

If there is a power outage, the energy storage battery will supply power to the mains.
With Only Solar Power but No Mains

During the day time, solar power is given priority to power the load, and any excess energy generated is used to charge the lithium storage battery.

At night, the storage battery will supply power to the mains
Hybrid Solar Power and Mains

During the day, the mains and solar power work in tandem to power the load while simultaneously charging the batteries.

At night, if the lithium storage batteries are not fully charged, the mains continues to charge them while simultaneously powering the load.

If there's a power outage, the lithium storage battery will give power to run the load.
