Why Choose a 51.2V 100Ah LiFePO4 Lithium Battery Platform?

Product Overview

Our scalable 51.2V LiFePO4 platform — from 100Ah to 314Ah — adapts to any residential solar project size.

Lithium Iron Phosphate Chemistry Built for Longevity

LiFePO4 chemistry offers an unmatched combination of thermal stability, cycle life, and safety. Unlike NMC-based alternatives, this lithium iron phosphate battery pack delivers ≥6,000 charge cycles at 90% DOD with zero thermal runaway risk — meaning lower lifetime cost of ownership and higher installer confidence in the field.

Scalable 48V Architecture for Any System Size

Built on a true 48V LiFePO4 battery architecture (nominal 51.2V), a single unit stores 10.24kWh of usable energy. Connect up to 15 units in parallel to build systems up to 153.6kWh — giving EPCs the flexibility to right-size every residential project without sourcing multiple SKUs.

Solar Battery Storage System Features That Installers Trust

Key Features

Designed for real-world solar installs — rack-mountable, inverter-compatible, and built to perform in demanding conditions.

Intelligent Battery Management System (BMS)

The integrated BMS provides multi-layer active protection across overcharge, over-discharge, overcurrent, short circuit, and temperature extremes. Cell balancing, SOC/SOH monitoring, and fault diagnostics are communicated in real time via CAN, RS485, and RS232 — giving installers full visibility and reducing after-sales support calls.

Stackable 51.2V 200Ah LiFePO4 rack battery modules connected in parallel — up to 15 units

Stackable Rack Module — Up to 15 Units in Parallel

The standardized 19-inch rack-compatible form factor (605×383×240mm, 77kg) installs cleanly into server cabinets or purpose-built enclosures. The stackable battery module design eliminates custom racking costs and cuts on-site installation time significantly compared to traditional flat-pack or floor-standing alternatives.

Deep cycle LiFePO4 lithium battery operating in wide temperature range from -20°C to 60°C

Deep Cycle Performance Across a Wide Temperature Range

Rated for discharge from -20°C to +60°C and charging from 0°C to +60°C, this deep cycle lithium battery performs reliably in garages, utility rooms, and unconditioned spaces across climate zones — from hot Australian summers to cold Central European winters.

Built-in DC isolation switch on 200Ah lithium battery pack for safe manual disconnection

Built-In Safety Isolation Switch

Each unit ships with an integrated DC isolation switch, allowing safe manual disconnection during maintenance, commissioning, or emergency shutdown without requiring additional external components or added BoS cost.

Solar Energy Storage System Applications

Applications

From single-family homes to multi-unit residential projects, this battery fits the most common solar-plus-storage scenarios.

Residential Solar Self-Consumption

Maximize solar self-consumption by storing excess daytime PV generation and discharging during evening peak demand. A single 10.24kWh unit covers average nightly household loads; stacking 2–4 units supports zero-export and off-grid-capable designs.

200Ah lithium battery providing home backup power and grid resilience for solar energy storage

Backup Power & Grid Resilience

Provide whole-home backup during grid outages. The high continuous discharge current (up to 120A) and intelligent BMS ensure seamless transition to backup mode — protecting sensitive appliances, home offices, and medical equipment without inverter overload.

48V LiFePO4 deep cycle battery installed in off-grid hybrid solar energy storage system

Off-Grid & Hybrid Solar Installations

Ideal for remote properties, rural electrification, and hybrid solar systems where grid reliability is limited. The wide operating temperature range and high cycle life make this the preferred deep cycle lithium battery choice for off-grid EPCs and project developers.

Deye Inverter Compatible — Plug-and-Play Integration

Compatible Inverters

Pre-validated with Deye hybrid inverters via CAN BMS protocol — no manual parameter configuration required on-site.

Deye SUN Series (5kW–80kW)

Fully tested and documented for plug-and-play integration with Deye SUN-29.9K~50KSG01HP3 and SUN-80K-SG02HP3-EU-EM6 inverters. Connect via CAN to the inverter BMS port; the battery main module auto-negotiates SOC, charge limits, and protection thresholds. For single-module installs on Deye 29.9K–50K inverters, use the dual-port parallel shunt configuration (P1+/P1– → BAT1; P2+/P2– → BAT2) to maximize power delivery.

Broad Third-Party Inverter Compatibility

Beyond Deye, the CAN/RS485/RS232 multi-protocol BMS supports integration with most leading hybrid inverter brands. Contact our technical team for a validated compatibility list covering SolarEdge, Growatt, Sungrow, Victron Energy, Fronius, and GoodWe.

At the recommended 90% depth of discharge, the 51.2V 200Ah unit delivers 9,216Wh (9.22kWh) of usable energy per cycle. This is the figure to use when sizing residential solar-plus-storage systems, not the nominal 10.24kWh total capacity.

How many units can I connect in parallel?

Up to 15 units can be connected in parallel, scaling total system energy to a maximum of 153.6kWh from a single battery string. All units communicate through a shared CAN/RS485 bus managed by the master BMS module.

Is this battery compatible with Deye inverters out of the box?

Yes. The 51.2V 200Ah-LV has been tested and documented with Deye SUN series hybrid inverters (5kW–80kW range). Communication is established via CAN bus connected to the inverter's BMS port. Detailed wiring diagrams and inverter parameter settings are included in the installation guide.

What certifications does this battery hold?

The 51.2V 200Ah-LV holds CE, RoHS, IEC62619, MSDS, and UN38.3 certifications. The IEC62619 certificate covers both cell-level and system-level safety testing, making it compliant for residential installation in the EU, UK, Australia, and most international markets.

Can I order with my own brand name and packaging?

Yes. We offer full OEM private label services including custom branding, enclosure colors, BMS display graphics, and multilingual documentation. Minimum order quantities start at 20 units. Contact our OEM team to request a sample and discuss your project timeline.
