Solar MPPT Regulators, Pure Sine Wave Bi-Directional Inverters, Wind Turbine Controllers designed and manufactured by J&J ELECTRONICS.

Features:

• The MICROCARE Programmable Relay Interface 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 / parameters.
• 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).

LED Function:

• POWER – Green = Power is present
• TX        – Red     = Transmitting data
• RX        – Red     = Receiving data
• The PWR LED should be on at all times. The Two RED LED’s should be flashing with one second intervals.

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 on page 2.
