Why 24V?
A 24V system balances accessible cost, useful battery capacity and everyday 230V power without immediately stepping up to a larger 48V installation.
Build practical backup without the larger initial investment of a high-capacity whole-home system.
Keep refrigeration, lighting, communication and selected household devices available when needed.
Match 2.56kWh, 5.12kWh or 7.68kWh to your actual loads and preferred backup time.
Designed for real life
Built for focused, practical power—not unrestricted whole-home loads.
Protect refrigeration, lighting, WiFi, screens and security equipment.
Support practical daily power in weekend homes and rural buildings.
Run lighting, chargers and selected tools with sensible load management.
Back up monitoring, communications, lighting and compatible small pumps.
Interactive load planner
Select appliances that may run together. We’ll estimate running power, daily energy use and the closest system fit.
Refrigeration, connection, lighting and screens.
More storage helps when loads are scheduled sensibly.
Typical values are used for guidance. Actual appliance ratings vary.
How it works
See how energy moves through a practical 24V backup setup throughout the day.
Solar first
Available solar energy supplies connected appliances first. Energy not immediately used can charge the battery.
These systems are positioned for off-grid backup and local self-consumption, not certified grid-export operation.
Savings calculator
We’ve pre-filled an illustrative EU household electricity rate. The blue field is editable—replace it with the rate shown on your own bill.
Click or tap the number and enter your local electricity rate.
Illustrative estimate based on 90% usable system energy, your electricity price and the charging days selected. Direct daytime solar use is not included.
Actual savings depend on solar generation, household use, tariffs, system efficiency, battery condition, weather and installation. Solar panels are not included.
Battery value comparison
Two configurations can create the same nominal 24V storage capacity. The two-battery route reduces the number of battery cases and is used in our best-value 4.2K bundle.
7.68kWh nominal storage
Three battery units
Parallel 24V configuration
7.68kWh nominal storage
Two identical battery units
Series connection creates 25.6V 300Ah
Use only identical batteries approved for the intended series or parallel configuration. Fully charge and balance series-connected batteries before installation.
System comparison
Compare output, storage and the use case each configuration serves best.

Complete-system confidence
Appropriate inverter and battery sizing reduces voltage mismatches, undersized battery output and avoidable installation uncertainty.
Every recommended configuration is built around a 24V battery architecture.
Battery output and inverter size are considered together—not selected in isolation.
Choose capacity around the energy you need, not simply the largest inverter.
Ask one team about inverter, battery and system-level setup questions.
Solar panels, cables, protection devices and installation accessories are not included unless specifically listed. Professional installation is recommended.

Frequently asked questions
Clear answers to the questions that matter when planning a 24V solar backup system.
No. The configurations on this page include the selected inverter and battery system only. Solar panels, cables and installation protection devices are sold separately unless specifically stated.
Yes. The highlighted live price is calculated with the automatic 10% bundle discount included. The crossed-out amount shows the original system price, and the saving badge shows how much you save.
Savings depend on how much stored solar energy you use instead of buying electricity from the grid. Replace the calculator’s pre-filled value with the electricity price shown on your own bill.
Yes. Two identical 12.8V 300Ah batteries can be connected in series to create a nominal 25.6V 300Ah battery bank. Fully charge and balance both batteries before connection.
Expansion rules depend on the selected battery. Combine only identical batteries with the same model, capacity, BMS specification, age and operating condition.
That depends on which appliances run at the same time. These systems are designed primarily for essential loads, small homes, cabins, workshops and selected off-grid applications—not unrestricted whole-home high-power use.
When correctly installed and configured with sufficient battery energy, the inverter can continue supplying connected backup loads without grid power.
Yes. The system involves high-current battery wiring, AC output, solar input and electrical protection devices. Installation should be completed or inspected by a qualified professional.
