What is a LiFePO4 battery?
LiFePO4 is a lithium iron phosphate battery that offers significant advantages over batteries in other technologies. Thanks to its long lifetime, performance, lightweight and sizes it will be perfect as a power source for boats, electric vehicles or solar installations.
Despite the higher price, LiFePO4 batteries are characterized by a much lower operating cost, which means that the purchaser pays for itself very quickly. Over the lifetime of the LiFePO4 battery costs more than 100% less than a standard AGM battery, making them a worthwhile investment and a smart long-term solution.
Mulit-level energy management, longer battery life
One-button switch machine, more convenient operation
Modular, ultra-thin wall haging design, convenient installation
Multiple parallel support, high current charge and discharge.
High BMS compatibility, perfect match of energy storage inverter.
The adoption of high-performance processors, international brand devices, better stability.
Residential grid-tied solar with backup power
Secure power for your home during grid outages by retrofifitting your grid-tied system with backup power using proven zetara power's solutions.
Self-consumptionExtra PV power for battery charging. When PV power is low or none, load consumption should take power from the battery fifirst, and from the grid as little as possible.
Off-grid power supplyCut your consumption peak and save money by reducing loads. When the grid is offline, the storage system should automatically switch to off-grid powering in less than 1s, for external emergency load powering

Battery management system BMS
The batteries are equipped with a high-class BMS (Battery Management System). The task of this system is to monitor the voltage and temperature of the cells during both charging and discharging. If dangerous values are exceeded, the system cuts off the power supply, thus ensuring the safety of the battery, connected devices and most of all, the user!
