An Introduction to Protective Relays for Solar-Plus-Storage Systems Electrical relays, protective devices used to switch power on or off for parts of a circuit, have been integrated into circuits for nearly two hundred years.
Protective relays monitor voltage, current, or frequency and respond to abnormal conditions by opening or closing a switch to isolate parts of a circuit. Based on their switching mechanism, relays can be divided into two categories: electromechanical and static. Electromechanical protective relays use moving parts to open and close switches.
Power relays are required as safety measures to protect the power supply system. Power relays are required as safety measures in the event of a defect in or malfunction of the battery or system. AQ-A SSR (PhotoMOS) is used to switch charge and discharge. We recommend solid state relays for applications where there will be frequent ON/OFF switching.

1,000 V DC is Max. switching voltage. The rating is 400 V DC. Relays are used for safety cutoff on the grid (power network). The relay must cutoff the circuit to prevent abnormal currents that occur from affecting the commercial power supply. Power relays are required as safety measures to protect the power supply system.
Relays use voltage, current, and frequency set points to initiate an action, and can perform a wide range of functions — from grid isolation to load shedding to turning on a backup generator.
