Description

MARSARIVA MR-LFP48-100-WMD 51.2V 102Ah Lithium Battery

Designed for modern homes, retail stores, IT server nodes, clinic consultation rooms, and executive offices across Bangladesh requiring reliable power backup during grid outages, the MARSARIVA MR-LFP48-100-WMD provides high energy density in a sleek, space-saving form factor. It replaces conventional bulky lead-acid, tubular, and gel battery banks with an advanced, maintenance-free Lithium Iron Phosphate energy storage platform that requires zero distilled water maintenance and emits no harmful fumes.

The core of the battery is engineered with BYD Grade-A 102Ah LiFePO4 prismatic cells operating on a standard 51.2V nominal low-voltage DC bus architecture. With an operating voltage window of 43.2V to 58.4V DC and passive cell balancing, the unit delivers 5.22 kWh of gross storage energy. Its advanced chemistry provides more than 6,000 deep cycles, enabling well over a decade of continuous daily cycling without the rapid plate sulfation and capacity degradation typical of traditional battery chemistries.

The integrated smart Battery Management System (BMS) manages balancing and real-time monitoring across individual cell voltages, temperature gradients, and current paths. It features multi-tiered hardware protections against overcharge (58.4V cut-off), over-discharge (43.2V under-voltage protection), charge overcurrent (110A trip), discharge overcurrent (125A trip), short circuits, and thermal extremes. For critical facility and home safety, the unit incorporates an internal automatic aerosol fire extinguisher that activates in the event of thermal anomalies. With dual CAN, RS485, and RS232 communication interfaces, the battery supports closed-loop integration with popular hybrid solar inverters—including Solis (S6 low-voltage series), Growatt, Deye, Victron Energy, GoodWe, Voltronic, SofarSolar, and Must. For expanding power needs, up to 15 battery units can be connected in parallel, scaling storage from 5.22 kWh up to a 78.3 kWh commercial microgrid.

Constructed using high-durability SPCC cold-rolled steel ($398 \times 198 \times 600\text{ mm}$, 45 kg), the enclosure supports versatile deployment as either a wall-mounted or a floor-standing system. Real-time performance indicators—such as State of Charge (SoC), State of Health (SoH), cell voltages, temperatures, running power, and alarm logs—are easily accessed via the front-facing 4.3-inch color LCD touch screen.
