The Dyness Tower TS21 enables you to use solar energy generated during the day in the evening and at night, reducing low-value grid exports and maximising self-consumption at the full retail electricity price. With a usable capacity of 20.245 kWh and a continuous power of 12.78 kW, the Tower TS21 is particularly well suited for homes with a high daily consumption, a heat pump, an electric vehicle or multiple high-demand appliances, where ample capacity must remain available throughout the night.
