INVERTOR SERIES

Market-specific solutions - developed together with the customer

Working in partnership with our customer, ODU created innovative solutions for operating efficiency and safety with the Sunny Boy inverter Electronic Solar Switch ESS I and ESS II. The Electronic Solar Switch is integrated into a handle that completely covers all DC plug connectors and so prevents them from being activated under load. Only the ESS is pulled under load, the resulting electric arc voltage causes the special electronics to cut off power. As such it is no longer necessary to integrate a separate mechanical switch disconnector into the DC distribution - the modules can be connected directly to the inverter. DIN VDE 0100-712 is also observed, so the ESS provides maximum protection from faulty devices or improper disconnection procedure of the electrical components of a solar plant.
