EK Series LiFePO4 batteries are designed specially for residential and small commercial solar energy storage system. By using the latest battery technology of LiFePO4(Lithium Ion Phosphate) and Enerri’s patented smart BMS(Battery Management System), EK series batteries offer a safe and reliable energy storage solution for homes looking for green energy transition.

EK Series has 4 models of capacities ranging from 20.48kWh to 35.84kWh and of voltage 204V-358V. Due to its modular design, the system can also be extended to maximally 15 units in series of 768V and 76.8KWh capacity. 

FEATURES

LiFePO4 - Lithium Ion Phosphate

LiFePO4 is one of the latest Lithium Ion Battery technology which offers a much higher energy density than legacy lead acid batteries. Meanwhile, LiFePO4 battery are also known as the safest Lithium Ion battery, due to its non-flammable electrolyte which makes LiFePO4 are extremely unlike to catch fire.

Tier 1 Grade A New Prismatic Cells

Enerri insists on only using brand new Grade A Prismatic LiFePO4 cells from Tier 1 brands, such as EVE/CATL/REPT, etc. Top quality cells ensure the battery can safely operate with high energy storage performance during the whole life time above 6000 cycles.

Enerri promises NEVER using recycled or grade B cells in all our energy storage batteries.

All EK Series LiFePO4 batteries come with EVE brand new grade A prismatic LiFePO4 cells. 

5 Year Warranty (10 Years Optional)

EK Series batteries come with a standard 5 years local service warranty, and an optional 10 years warranty service. We have service centers not only in our China factory but also in our branch office in Manila, Philippines.

Long-Lasting

EK Series batteries are designed for life time of >6000 cycles or 10+ years, with 90% DOD and 80% energy capacity remained.

Smart BMS

EK Series batteries are equipped with 100A smart BMS with full monitoring and protection functions. Our BMS also offer optional Bluetooth connection for easy inspection of battery data. 

High Efficiency

Due to its higher voltage and less current advantages, EK battery system operates with lower heat generation and less energy self-consumption. EK Series batteries offer a 10% higher system energy efficiency comparing to low voltage systems. Less current can also save power cable cost for customers.

Built-in Safety System

All EK Series batteries are protected with smart BMS and independent breaker offering comprehensive safety measures, including overcharge, over-discharge, over-voltage, low-voltage, overloading, overheating, low temperature, short circuit, excessive low self-discharge rate, etc.

Perfectly Matching 20+ Inverters

EK series batteries have integrated communication protocols not only of Enerri inverters, but also of majors brands inverters, such as, Deye, Growatt, Solis, Megarevo, Luxpower, SMA, MPP, Victron, Voltronic, etc.

Environmentally Friendly

LiFePO4 batteries do not contain any toxic materials and any rare-earth elements, and are easy to be recycled.

Customization

Except our standard battery models in EK series, we also offer OEM and ODM service for various custom requirements, including capacity, voltage, IP grade, charge/discharge rate, dimensions, etc.
