Protection & Monitoring

AC Surge Protection Device Type 2 Single Phase 230V Solar Inverter

The connection of the PV to low voltages should be protected. Surge protectors are designed to protect against the overvoltages caused by lighting or from external AC source. A diesel generator or the national grid may also cause voltage disturbances that will damage the electronics of the inverter. 

Technology: High energy varistor with thermal fuse.
