Lovsun 51.2V 314Ah 16kWh Solar Lithium Battery
16 kWh / 51.2 V
Lovsun 51.2V 314Ah 16kWh Solar Lithium Battery is a LiFePO4 storage battery rated at 16 kWh / 51.2 V for solar self-consumption and backup duty.
What This Product Changes On Your Project
- 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
- 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
Application Scenarios
- 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
- Telecom and monitoring cabinets where a site visit is expensive
- Off-grid cabins, farms and workshops running entirely on PV and storage
Who It Is For
- System integrators building backup and off-grid packages
- Telecom and infrastructure operators replacing lead-acid at remote sites
- Off-grid property owners sizing a standalone power system
- Solar installers specifying residential and light commercial storage
Problems It Solves
- 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
- Solar output exported at a low feed-in tariff and bought back at a high retail one
- Outages that take critical loads down with no transfer time budget
Technical Features
- 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
- Over-voltage, under-voltage, over-current, over-temperature and short-circuit protection
- CAN and RS485 interfaces for inverter handshake and state-of-charge reporting
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 | 16 kWh |
|---|---|
| System voltage | 51.2 V |
| Cell capacity | 314 Ah |
| Brand | Lovsun |
Quality Control
- 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
- Aged and burn-in run before packing, so early-life failures happen in the factory
- Serialised traceability from cell batch to finished unit
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
