Lovsun HV 51.2V 100Ah LiFePO4 Rack Battery
100 Ah / 51.2 V
Lovsun HV 51.2V 100Ah LiFePO4 Rack Battery is a rack-mounted LiFePO4 battery module rated at 100 Ah / 51.2 V, designed to be stacked in a 19-inch cabinet so capacity is added one module at a time as the load grows.

What This Product Changes On Your Project
- 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
- No electrolyte maintenance, no equalisation charging and no ventilation requirement
Application Scenarios
- Off-grid cabins, farms and workshops running entirely on PV and storage
- Small commercial premises cutting evening peak import
- Marine, RV and mobile installations replacing lead-acid banks
- Residential solar self-consumption, storing midday PV for the evening load
- Backup supply for homes and small offices on an unstable grid
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
- Outages that take critical loads down with no transfer time budget
- 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
Technical Features
- 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
- State-of-charge indication at the unit, not only through the inverter app
- LiFePO4 cells with an integrated BMS handling balancing and protection
Published Specification Data

Quality Control
- 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
- Insulation and dielectric withstand testing on completed assemblies
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
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. |
Getting This Product Right On Site
- 1
Set charge and discharge limits in the inverter to match the battery's rated current
- 2
Check the state-of-charge reporting and firmware version at each annual service visit
- 3
Confirm the inverter model and communication protocol before ordering, so the handshake is verified not assumed
- 4
Mount in a dry, ventilated space within the stated operating temperature range
- 5
Torque terminals to the value in the manual and re-check after the first week of cycling
