The Programmable Relay Interface can be used as a Load shed controller, Day night switch, Generator controller or to facilitate our Solar Assist Function where the MPPT decides (based on user selectable conditions) when to power the LOAD / House using Solar / Wind power and when to power the LOAD / House via an external supply (like Eskom or a backup generator).

This unit can be used in conjunction with any of the MICROCARE LCD MPPT range. The MPPT can be programmed to switch the relay at selectable voltages / conditions / parameter.

Relay Function

* Load shed controller      

- Relay switches off when battery voltage falls below the user selected battery low voltage.
- Relay switches on when battery voltage rises above the user selected battery good voltage.

* Day Night Switch            

- Relay switches on when panel voltage falls below the battery voltage.
- Relay switches off when panel voltage rises above the battery voltage.

* Generator controller     

- Same operation as Load shed controller.
- Connect COM – NC (normally close) connections to generator remote start.

* Solar Assist Function      

- Same operation as Load shed controller.
- See diagram under images.

Technical Specifications

* Output Current Rating: 12 / 40  amps
