Load Control Example (SOC Trigger)

Relays are useful for controlling the power on loads you want available without over-discharging the battery. This is especially important on loads that require huge amounts of energy.

In this example, the batteries are powering three large loads: an EV charger, air conditioner, and oven.

Activated: 5 minutes after the battery SOC rises above 60%

Deactivated: 1 minute after the battery SOC drops below 25%

Relays 1, 2, and 3 are used to control when batteries are used to power a load. The relays are closed (activated) 5 seconds after the battery SOC rises above 60%, which closes the circuit to allow energy flow and can be used to power the associated load. After 5 seconds after the battery SOC drops below 25%, the relays are opened (deactivated) to stop the flow of power from the batteries, which protects the batteries from over-discharge.
