ESS Z is a new modular lithium-ion based energy storage system, which stores the surplus of the collected solar energy for later use. Energy can either be directed into the storage system or be fed into the public grid via aninverter. Energy is available as required: in the evening, at night, or on a cloudy day. With the ESS Z System, consumers of solar power become more independent from electricity prices and use their home-made eco-electricity when they need it.

From June 2021, we will offer you the ESS Z energy storage system, a new generation of efficient battery storage systems in our ESS store.
