Renewable Energy - DC Disconnect, Overcurrent Protection and Error Signalling

As investments in the production of renewable energy continues to increase, the importance of protecting these new technologies with accurate overcurrent protection and integral error signalling builds. E-T-A's system solutions, DC disconnect switches, firefighter switches, circuit breakers, isolators, power distribution systems, electronic relays and emergency switches ensure dependable solutions for the latest state-of-the-art green technologies entering the market today including: photovoltaic technology as well as hydroelectric and wind power generation.

E-T-A works closely with companies in the renewable energy sector developing products including:

  • Remotely controlled circuit breakers and DC disconnect switches
  • Isolation and disconnection of high DC voltages in inverters and generator junction boxes
  • Protection of stand-alone systems 
  • Electronic circuit protectors, ideally suited to battery-buffered DC 12 V and 24 V DC applications due to their low power consumption
