ESS X is a 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 an inverter. With the ESS X System, consumers of solar power become more independent from electricity prices and use their home-made eco-electricity when they need it. The design of the system is based on a modular principle: Depending on the desired storage capacity, the battery modules can be adapted to the needs of the user. For the recommended configuration of the storage system, please refer to the product brochure. Set consisting of: ESS X, CAN terminating resistor (integrated in battery), operating manual, installation checklist, warranty card and test certificate.
