Key Benefits

What This Product Changes On Your Project

LiFePO4 chemistry - a flatter thermal profile and a longer cycle life than NMC at the same usable energy
Integrated BMS with cell balancing, over-current, over-temperature and short-circuit protection
Parallel expansion, so a system can be sized for today's load and extended later without replacing the first units
Standard CAN and RS485 communication for inverter handshake, rather than a closed protocol that locks the buyer to one brand
Usable depth of discharge that does not have to be derated the way lead-acid does

Application Scenarios

Residential solar self-consumption, storing midday PV for the evening load
Backup supply for homes and small offices on an unstable grid
Telecom and monitoring cabinets where a site visit is expensive
Off-grid cabins, farms and workshops running entirely on PV and storage
Small commercial premises cutting evening peak import

Who It Is For

Solar installers specifying residential and light commercial storage
Distributors and wholesalers stocking storage batteries for an installer base
System integrators building backup and off-grid packages
Telecom and infrastructure operators replacing lead-acid at remote sites

Problems It Solves

Battery rooms that need ventilation, bunding and routine electrolyte maintenance
Closed inverter-battery protocols that force a whole-system replacement to change one component
Lead-acid banks that have to be oversized because only part of the capacity is usable
Replacement cycles every few years and the disposal cost that comes with them

Technical Features

LiFePO4 cells with an integrated BMS handling balancing and protection
Over-voltage, under-voltage, over-current, over-temperature and short-circuit protection
CAN and RS485 interfaces for inverter handshake and state-of-charge reporting
Parallel connection of multiple units to build capacity in steps
Enclosure and terminal layout designed for a single-installer fit

Specifications

Published Specification Data

These figures come from the manufacturer datasheet for this model. Where a value you need is not listed, ask for the full datasheet rather than assuming a typical figure.

Energy capacity	5 kWh
System voltage	51.2 V
Cell capacity	100 Ah
Brand	Lovsun

Quality Control

Serialised traceability from cell batch to finished unit
Packing inspection and photo record before container loading
Incoming inspection of cells, power electronics and structural parts before assembly
Capacity and internal-resistance grading so cells within a pack are matched
Full-function test on every finished unit, not a sample from the batch

Customization Options

Capacity configuration and number of parallel units
Communication protocol matched to the inverter brand on site
Enclosure finish and customer branding
Mounting variant - wall, floor or rack - for the available space

Comparison

How It Compares With The Alternatives

Lead-acid batteries	Usable depth of discharge is far higher, so a lead-acid bank has to be specified much larger for the same usable energy - and replaced far sooner.
NMC lithium batteries	LiFePO4 gives up some energy density and gains thermal stability and cycle life, which is the trade most stationary storage buyers want.
A larger single battery	Parallel modules let the system be sized for today's load and extended later, instead of paying up front for capacity that idles for two years.

Use Guide

Getting This Product Right On Site

1
Mount in a dry, ventilated space within the stated operating temperature range
2
Torque terminals to the value in the manual and re-check after the first week of cycling
3
Set charge and discharge limits in the inverter to match the battery's rated current
4
Check the state-of-charge reporting and firmware version at each annual service visit
5
Confirm the inverter model and communication protocol before ordering, so the handshake is verified not assumed

Lovsun 51.2V 100Ah 5kWh Solar Lithium Battery - Buyer Questions

What temperature range can the battery work in

The operating and storage temperature ranges are in the specification table. Charging has a narrower window than discharging, which matters for unheated installations.

Which inverters is this battery compatible with

It communicates over CAN and RS485 and is used with common hybrid inverter brands. Tell us the exact inverter model you plan to use and we will confirm the protocol before you order.

What is the minimum order quantity

One unit for a sample or a single installation. Container quantities are priced for distributors and installers ordering to stock.

How many units can be connected in parallel

Parallel capability is stated in the specification table for this model. Beyond that count, capacity is added with a second bank under separate inverter control.

What is the warranty and what does it cover

Warranty terms are confirmed in writing with the quotation and depend on the model and destination market. Ask for the warranty statement before you place the order.

How is the battery packed for export

Units are packed to UN38.3 transport requirements for lithium batteries, with the documentation the carrier needs. Confirm air or sea freight when you enquire, as the requirements differ.
