HE-V (2a 20A 1,000V DC*)
High-voltage cutoff relay capable of simultaneously cutting off the positive (+) and negative (-) terminals by serially connecting the 1 Form A contact. Up to 1,000V DC cutoff

*1,000 V DC is the maximum allowable voltage when each 1 Form A contact is connected in series. The rating is 800 V DC.
●When something shades the solar panels or a defect occurs, the total power generation efciency of the system decreases.
In such cases, the total power generation efciency can be maintained by bypassing low-efciency panels or cutting off strings using relays.
●In case of a disaster, such as re, system safety can be maintained by shorting each solar panel. (E.g. electrical shock prevention of reghters)
●Remote control is possible for maintenance work, reducing maintenance costs.

●In case of a disaster, such as re, system safety can be maintained by cutting off the DC line.
●Remote control is possible for maintenance work, reducing maintenance costs.
●Large current cuttoff possible during malfunction when connecting storage battery. (80 to 300A type)
