Lightwave Lithium Battery (LW-LiFe-15KW)
The Lightwave LW-LiFe-15KW is a 15.36kWh lithium iron phosphate (LiFePO4) battery for 48V solar, hybrid and off-grid power systems. It stores enough energy to run a business or large household through long outages and overnight. It suits commercial premises, institutions and student hostels that need high-capacity storage and strong power output from a single unit.
Key Features & Benefits
- 15.36kWh capacity in one unit: The battery stores 15.36kWh, about 12.3kWh usable at 80% depth of discharge. As a result, one unit replaces three 5kWh batteries. This cuts wiring, saves floor space and simplifies maintenance.
- 200A charge and discharge: The battery supports up to 200A in both directions, about 10.2kW at 51.2V. Consequently, one unit can support an 8kW or 10kW 48V inverter at full output. High charge current also means faster recharging from large solar arrays.
- 6,000+ cycle lifespan: The battery is rated for over 6,000 cycles at 80% depth of discharge. At one cycle per day, that equals more than 16 years of theoretical use. This makes it a long-term energy asset rather than a recurring expense.
- Multi-level BMS protection: The smart BMS monitors voltage, current and temperature continuously. It protects against overcharge, over-discharge, short circuits and thermal faults. Additionally, alarm and capacity indicators warn you of problems early.
- Wide inverter compatibility and easy setup: RS485, CAN and RS232 ports connect the battery to inverters such as Growatt, Victron, Schneider and Pylontech-protocol models. For instance, DIP switches set communication addresses, and an LCD display shows battery status at a glance.

Use Cases & Applications
For Business
Long outages can shut a business down for a full day. This battery keeps operations running instead. For example, an office with ten computers, networking, lighting, CCTV and a fridge might draw about 1,000W. The battery can support that load for roughly 11 hours after inverter losses.
It works well for:
- Offices and co-working spaces: Run computers, internet, printers and lighting for a full working day.
- Supermarkets and retail shops: Keep POS systems, lighting and refrigeration running through extended power cuts.
- Clinics, pharmacies and labs: Maintain lighting, computers and cold storage during outages.
- Schools and institutions: Power computer labs, administration offices and security systems.
- Solar installers: Build 8–10kW 48V hybrid or off-grid systems around a single battery.
For Students
This battery suits student hostels, large shared houses and campus study centres. For instance, a hostel floor with ten laptops, Wi-Fi, lighting and a shared fridge draws about 600W. The battery covers that for roughly 18–19 hours. As a result, residents can study and stay connected through overnight outages.
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 or Schneider, or an inverter that supports the Pylontech protocol. Then set the inverter’s battery type to lithium or the matching protocol.
Can it run an 8kW or 10kW inverter?
Yes. The 200A limit at 51.2V gives about 10.2kW. Therefore, one battery can support an 8kW or 10kW 48V inverter at full output. Keep in mind that full load drains the battery in just over an hour.
How long will it power my devices?
Divide the usable energy (about 12,300Wh) by your load in watts. Then subtract 5–10% for inverter losses. For example, a 2,000W load runs for roughly 5.5–6 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.
Should I buy one LW-LiFe-15KW or several smaller batteries?
One LW-LiFe-15KW means fewer connections, less wiring and a single unit to monitor. By contrast, three LW-LiFe-5KW units give redundancy and are easier to move individually. Choose the 15KW when space and simplicity matter most.
How does it compare to lead-acid batteries?
Matching 12.3kWh usable with lead-acid would take a very large bank, since lead-acid is usually discharged only to about 50%. That means roughly 24–25kWh of lead-acid capacity, requiring far more space and regular maintenance. This single LiFePO4 unit needs no maintenance.
Important Notes (Merchant Verification Before Publishing)
- Package dimensions: The manufacturer lists 54 × 23 × 45, identical to the 5kWh and 10kWh models. This is almost certainly a copy error for a 15kWh unit, so it was left out. Confirm the actual dimensions and weight.
- Weight and handling: A 15kWh LiFePO4 unit is typically very heavy. Confirm the weight and any handling or delivery requirements.
- Datasheet: The official datasheet PDFs for this range have been 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. Confirm separate charge and discharge temperature ranges.
- Mounting type: Not stated. Confirm whether the unit is floor-standing, wall-mounted or on wheels.
- Parallel expansion: DIP switches suggest multi-unit support. Confirm the maximum number of units in parallel.
- Remote monitoring/app: Not listed for this model. Do not claim it 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.
