The energy management relays refer to switches that enable loads like hot water to be turned on and off. This process depends on the amount of excess solar electricity available. Relays are used to shut down electricity grids safely. When an abnormal current is produced in an inverter, the current must be cut to prevent it from affecting its power supply side. As part of the safety measures to safeguard electric power grid systems, inverters are outfitted with high-capacity relays.
The contacts of the relay for standalone operations are turned off during normal inverter operation. However, the inverter is intended to turn the relay’s contacts ON to initiate its standalone function in the event of a blackout due to a problem. Relays are used for safety and stand-alone activities.
What are Energy Management Relays Used For?
1. For Safety Cut-off on the AC side: On the grid, relays are used for safety shutoff (power network). You can stop any abnormal current flowing in the circuit which may affect the commercial power source. To do so, the relay must shut off the circuit. To safeguard the power delivery system, power relays are necessary.
2. For operation in stand-alone mode: During a power outage, the relay contacts will be ON, allowing for the use of the stand-alone feature. To operate in stand-alone mode, switches are used.
3. Eco-POWER METERs/Programmable Displays: These are used to show how much power is generated by a power conditioner and sold or purchased from a photovoltaic power generation device. Reverse power (tidal current) to grid monitoring is necessary for photovoltaic and fuel cell power generation devices connected to storage batteries. Eco-POWER METERs are perfect for reverse power (tidal current) surveillance because they have a fine current detection feature.
