LiFePO4 Batteries

EAST LiFePO4 batteries are the storage behind every MyEnergy system: lithium iron phosphate chemistry chosen for safety, thousands of deep cycles and zero maintenance — the practical opposite of the lead-acid banks Sri Lankan homes used to rely on for backup.

The range covers every common installation. Wall-mounted 5.22 kWh units suit compact homes that want clean backup without floor space. Stacked modules (5.12 kWh and 16 kWh classes) sit under or beside the inverter and grow with you — start with one module and add more later without changing the inverter. Rack-mounted 48 V batteries fit standard cabinets for offices and technical rooms, and 750 V high-voltage modules serve three-phase homes and commercial systems, expandable to 60 kWh per cluster.

Every battery ships with an integrated BMS that manages cell balancing, temperature and protection, and pairs natively with EAST hybrid inverters and all-in-one ESS cabinets. That single-brand pairing matters: one monitoring app, one warranty chain, one installer responsible for the whole system.

What a battery does for you in Sri Lanka: it keeps essential circuits running through power cuts, stores your rooftop solar for use after sunset, and — on an applicable Time-of-Use tariff — shifts consumption out of the expensive evening peak. Sizing is straightforward: around 5–10 kWh covers lights, fans, router, TV and a fridge through a typical outage; add air-conditioning or a pump and 10–20 kWh is the realistic band. Use the build-my-system tool for a sizing estimate from your actual loads, or request a quotation — every MyEnergy install includes a site survey, professional installation island-wide, and warranty support of up to 10 years on eligible ESS packages.
