BATTERYGet a quote HOME BATTERY STORAGE
Store cheaper overnight electricity for the day ahead. Choose a modular battery with a separate inverter, or a DX all-in-one system with both in one unit.
Works without solar. Can also store surplus generation from compatible solar panels.
You do not need to choose a model first. Our calculator suggests a battery size from your electricity bill or daily use. Then we check the inverter, tariff and installation with you.
Find my system and savings ↗TWO WAYS TO STORE
Start with the storage you need, then choose the format and power that fit your home.
SOLPLANET / ASW
The blue Ai-LB-G3 battery stores the energy. A separate ASW hybrid inverter manages power between the battery, your home, the grid and compatible solar.
DX SERIES
The charcoal DX all-in-one combines battery storage and a built-in inverter. Our listed 10, 15 and 20 kWh packages use the 5 kW configuration.
SOLPLANET AI-LB-G3
From 10 to 25 kWh, the modules can form one stack. The width and depth stay the same; the stack simply gets taller as capacity increases. Each 5.12 kWh module is 630 mm wide, 320 mm high and 185 mm deep.
| Package name | Nominal energy | Usable energy¹ | Modules | Dimensions | Module weight² |
|---|---|---|---|---|---|
| 10 kWh | 10.24 kWh | 9.72 kWh | 2 | 630 × 640 × 185 | 92 kg |
| 15 kWh | 15.36 kWh | 14.59 kWh | 3 | 630 × 960 × 185 | 138 kg |
| 20 kWh | 20.48 kWh | 19.45 kWh | 4 | 630 × 1,280 × 185 | 184 kg |
| 25 kWh | 25.60 kWh | 24.32 kWh | 5 | 630 × 1,600 × 185 | 230 kg |
¹ Manufacturer usable-energy figures measured at 95% depth of discharge, 25°C and 0.5C charge/discharge. Energy delivered to appliances also depends on system losses, settings and operating conditions. ² Module totals exclude the 2.6 kg base and separate inverter. Product dimensions exclude installation clearances.
The five-module arrangement is the largest single tower documented for this range: 25.6 kWh nominal capacity, sold as our 25 kWh package. For larger capacities, explore the suggested two-stack layouts below.
Our calculator uses rounded package capacities and a stated 90% usable-capacity assumption. For example, the 10 kWh package is modelled as 9 kWh per day. The manufacturer’s laboratory figures above describe the hardware; they do not replace the calculator’s assumptions.
Estimate savings for my home| Feature | Manufacturer specification |
|---|---|
| Cell chemistry | Lithium iron phosphate (LiFePO4 / LFP) |
| Protection | IP66; indoor/outdoor installation subject to siting requirements |
| Operating temperatures | Charging: −8 to 58°C · discharging: −18 to 58°C |
| Cooling / communication | Natural convection · CAN communication |
| Battery round-trip efficiency | ≥95% (battery figure, not complete AC system efficiency) |
| Cycle-life test | 6,000 cycles at 0.5C, 25°C, one cycle/day, 90% depth of discharge and 70% end-of-life capacity |
| Built-in protections | Battery management system, integrated fire suppression, MOSFET and dual fuse protection |
Safety features reduce risk; correct installation and operation remain essential. Cycle-life testing is not a guaranteed service life or a warranty. Maximum power also depends on the inverter and installed battery configuration.
MORE FLEXIBILITY AT HOME
A larger system can be planned around two smaller stacks. This gives you another layout to consider where height is limited or one tall unit would be less practical.
30 kWh PACKAGE
Two three-module stacks, each approximately:
40 kWh PACKAGE
Two four-module stacks, each approximately:
Suggested layouts, confirmed at survey. These are the dimensions of each stack, not the total installation space. The final positions, compatible equipment and approved interconnections must be confirmed, with room for mounting, cabling, access, required clearances and the separate inverter. Two stacks do not necessarily take up less total floor or wall space.
Our 35 kWh package also remains in the standard range; its arrangement and dimensions are confirmed individually. Package capacities are rounded names; the exact nominal totals for the suggested 30 and 40 kWh arrangements are 30.72 and 40.96 kWh respectively.
DX SERIES ALL-IN-ONE
A built-in inverter and battery in a slim, integrated format, with app monitoring and compatible solar inputs.
The figures below apply to the current 5 kW models in the newer DX datasheet. Earlier brochures also show 3.6 kW variants. Your written quote will identify the exact model being supplied.
| Model / package | Nominal capacity | AC output | Dimensions | System weight |
|---|---|---|---|---|
| 5K0L-T2 / 10 kWh | 10.24 kWh | 5 kW | 675 × 1,210 × 200 | 154.4 kg |
| 5K0L-T3 / 15 kWh | 15.36 kWh | 5 kW | 675 × 1,575 × 200 | 208 kg |
| 5K0L-T4 / 20 kWh | 20.48 kWh | 5 kW | 675 × 1,940 × 200 | 261.6 kg |
Model prefix: DX Energy-. The datasheet gives battery capacity, not a usable-energy value. Leave additional room for mounting, ventilation, access and cabling.
Charging temperature: 0–50°C. Discharging: −15–50°C. Natural cooling. Outdoor suitability depends on the proposed location and product installation requirements. Backup needs the optional EPS installation.
LIVING WITH YOUR BATTERY
Understand how the battery fits into your home before you choose it.
Monitor charge, discharge and stored energy through your system’s app. Solplanet systems use the Solplanet App; we’ll explain the connection and controls supplied with your chosen DX system.
Monitoring questionsBattery and inverter dimensions are only part of the picture. Access, mounting, cable routes, operating temperatures and required clearances all form part of your survey.
What the survey coversOur battery systems are offered with a 10-year product warranty, subject to the terms for the exact equipment supplied. We’ll provide the applicable cover and exclusions with your proposal. The optional EV charger has separate cover.
