The owners of a private house in Tysmenytsia needed a solution for reliable backup power without relying on diesel generators. Their key requirements included the ability to power essential household appliances, heating systems, and achieve cost efficiency by taking advantage of reduced electricity tariffs during the night. The project aimed to combine solar energy generation, battery storage, and intelligent load management into a single, stable energy system.
