Our proprietary hardware and software solutions for battery and appliance monitoring and control.


Unique patented autonomous fire protection system requiring no maintenance or control.


High quality LiFePO4 cells with chemical composition in the highest Grade A quality class from our verified manufacturers.


The BMS unit controls the charging and discharging of the battery and balances the cells to ensure reliable battery operation.


Temperature sensors of our own manufacture are placed at each cell junction to monitor the temperature of each cell.

Smart control system


This tool makes predictions of customer consumption (taking into account days off, time of year and specific customer consumption behaviour) and PV plant production (depending on its output, location, time of year or weather forecast) using artificial intelligence.

Data analysis

Through the savings calculation tool, we provide customers with an evaluation of the amount of savings achieved through smart control based on input data from invoice or consumption charts as well as data on existing or planned PV plants.

Solution design

This tool also allows you to design the optimal size of the PV plant and, if necessary, the capacity of the battery. Using mathematical formulas and evaluating countless different options ensures the most optimal result/design.

Achieving savings

Savings range between 8-25% (depending on battery capacity) due to the prediction of PV production and customer consumption as well as the smart operation of the battery, which is charged/discharged according to spot market prices. Savings start to show after 14 days of operation.
