The Lightwave LW-LiFe-5KW is a 5.12kWh lithium iron phosphate (LiFePO4) battery for 48V solar and backup power systems. It stores energy from solar panels or the grid, then powers your equipment during outages and at night. It suits businesses, home offices and shared student housing that need steady backup for heavier loads.
Key Features & Benefits
- Full 5kW output from one battery: The battery delivers up to 100A continuous at 51.2V, roughly 5.1kW. As a result, a single unit can support a 5kW 48V inverter at full output. You do not need a second battery just to reach rated power.
- 6,000+ cycle lifespan: The battery is rated for over 6,000 cycles at 80% depth of discharge. At one cycle per day, that is more than 16 years of theoretical use. Consequently, the cost per stored kilowatt-hour drops well below typical lead-acid banks.
- Smart BMS monitoring: The built-in battery management system tracks voltage, current and temperature continuously. It cuts power before unsafe conditions damage the cells or your connected equipment.
- Wide inverter compatibility: RS232, RS485 and CAN ports let the battery communicate with your inverter. For instance, it works with Growatt, Victron, Schneider, Voltronic and Goodwe. The inverter then reads the charge level and manages charging automatically.
- Built for multi-battery setups: An onboard DIP switch sets each battery’s RS485 address. Therefore, you can link several units into a larger bank as your power needs grow.

Use Cases & Applications
For Business
Outages cost sales, data and productivity. This battery keeps a full office or shop running rather than just a few essentials. For example, six laptops, a router, lighting, CCTV and a printer on standby draw about 600W together. The battery can support that load for roughly 6–7 hours.
It works well for:
- Retail shops and supermarkets: Keep POS terminals, lighting and display fridges running through power cuts.
- Offices and co-working spaces: Maintain computers, internet and printers without starting a generator.
- Clinics, pharmacies and salons: Keep lighting, computers and small appliances online during the working day.
- Solar installers: Build 48V hybrid systems that start with one battery and expand later.
For Students
This battery fits shared student housing, hostels and study centres better than a single room. For instance, a shared house with four laptops, a router and lighting draws about 350W. The battery covers that for roughly 10–11 hours after inverter losses. Additionally, residents can split the cost of a system that serves everyone.
Frequently Asked Questions
Will it work with my inverter?
It works with 48V inverters. However, it will not work with 24V inverters. For full communication, choose a supported brand such as Growatt, Victron, Schneider, Voltronic or Goodwe. Then set the inverter’s battery type to lithium or the matching protocol.
Can it run a 5kW inverter on its own?
Yes. The 100A limit at 51.2V gives about 5.1kW of continuous output. Therefore, one battery can support a 5kW 48V inverter at full load. Keep in mind that full load drains the battery in under an hour.
How long will it power my devices?
Divide the usable energy (about 4,100Wh) by your load in watts. Then subtract 5–10% for inverter losses. For example, a 500W load runs for roughly 7.5–8 hours.
How long does the battery last?
It is rated for over 6,000 cycles at 80% depth of discharge. At one cycle per day, that is more than 16 years. The manufacturer also offers an 8-year warranty.
How is this different from the LW-Life-5KW-24V?
Both store 5.12kWh. However, the LW-LiFe-5KW runs at 51.2V and 100Ah, while the 24V model runs at a lower voltage with roughly double the amp-hours. At the same 100A limit, this 48V model delivers about twice the continuous power. Choose based on your inverter’s battery voltage.
How does it compare to lead-acid batteries?
A 48V lead-acid bank needs four 12V batteries wired in series. These are usually discharged only to about 50% to protect their lifespan. By contrast, this single LiFePO4 unit gives about 4.1kWh usable and needs no maintenance.
Can I add more batteries later?
Yes. The DIP switch lets you give each battery its own RS485 address. As a result, you can link several units into one bank. Confirm the maximum number of units with the supplier first.
Important Notes (Merchant Verification Before Publishing)
- Datasheet: The official PDF datasheet is image-based and could not be text-extracted. Please verify specs against it directly.
- Temperature range: The -20°C to 65°C figure is a general operating range. LiFePO4 charging ranges are usually narrower, often around 0°C to 45–55°C. Confirm separate charge and discharge temperature ranges.
- Weight: 53kg is heavy for a 5.12kWh unit. Confirm whether this is the net weight or the gross (packaged) weight.
- Package dimensions: The 54 × 23 × 45 figure matches the 24V model’s listing exactly, and its unit is unstated. Confirm the actual unit and package dimensions.
- Mounting type: The manufacturer does not state whether this unit is rack-mounted, wall-mounted or floor-standing. Do not claim a mounting type until confirmed.
- Parallel limit: Confirm the maximum number of units supported in parallel.
- Display/app: No LCD, Bluetooth or app monitoring is listed. Do not claim these features unless confirmed.
- Included accessories: Confirm whether communication cables, battery cables and mounting hardware are included.
- Local warranty: Confirm that the 8-year warranty is honoured through the Kenyan distributor, along with any cycle or usage conditions.
