Long-term electricity supply in off-grid mode

Дом с панелями
Do ignore the long-term power cutoffs due to your own off-grid power plant with large capacity accumulators.


Mark your energy consumption level and choose the optimal term of off-grid power supply. So you will determine the approximate cost of the station for your goals.

Every year we conduct a full inspection of the power plant, analyze the efficiency of modules using the thermal camera, check commutation and test the inverter at different load regimes.

Due to regular service maintenance we can provide a guarantee for installation up to 10 years. In addition, an official manufacturer guarantee is valid for all equipment.

We provide equipment with a smart monitoring system so that you can easily track and analyze the work of your power plant. In addition, our technicians can remotely check the equipment condition at any time and, if necessary, send a servicing team.
