The high-quality power storage units from RCT Power are among the most efficient battery storage systems on the market and have already received several efficiency awards. This aspect is very important for a special reason: If you consider a high-efficiency rate when you purchase your power storage unit, you not only save money but also actively contribute to climate protection. During the day, when the sun shines, your photovoltaic system usually produces more energy than your household consumes. Without a power storage system, the excess energy is fed into the grid. You have to buy it back at a higher cost. With an RCT Power electricity storage unit you store your solar power locally and use it whenever you need it, including night-time and days with very low or no sunshine. You use solar energy more sustainably and become more independent of external power suppliers. A perfect feeling.
