☀️ How can we store sunlight and continue using it after sunset?
In Suraia, Romania, a residential energy storage system combining the ESSIS SUN-6K-H3 6 kW hybrid inverter with the Powerbox16.0 16 kWh battery allows the customer to use solar energy during the day while storing surplus PV power for the evening and nighttime.
The SUN-6K-H3 coordinates the energy flow between the PV system, battery, grid and household loads. Meanwhile, the Powerbox16.0 stores surplus energy generated during the day and provides energy support when the household truly needs it. Its IP66 protection rating offers additional protection for everyday home energy use.
But this project was about more than equipment and installation.
After completing the system installation, we gathered around the barbecue with the customer and our local partners, sharing delicious food and enjoying relaxed conversations together. 🔥
For ESSIS, every installation means more than delivering an energy storage system. It represents trust, cooperation, and the opportunity to build genuine, lasting relationships with local families and partners.
