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 and  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)
