SUNSYS HES L is a native outdoor system that merges proven technologies to create an all-in-one solution that is greater than the sum of its parts. Partnering with CATL, Socomec has selected the EnerOne liquid cooled LFP battery system as the optimum battery for SUNSYS Hybrid Energy Storage. When it comes to safety, this system sets a new standard.
