Quick reference guide for the installation of REhub MPPT
Step 1
Prepare to connect
: Keep the cables ready. Draw the PV +Ve and -Ve wires to the battery
room. Make provision to mount the REhub on a wall close to the batteries and the Inverter.
Measure and cut a 6 Sqmm cable (RED) for connection between REhub and battery. Crimp
appropriate lugs to the cable ends.
Step 2
Make the Solar connections
: Measure Open Circuit voltage, ensure it is within REhub upper
limit, make the PV -Ve connection to REhub. Connect the PV +Ve to the PV +Ve terminal.
Step 3
Make the battery connections
: Measure the battery Voltage to make sure it is within the
operating limits of 12V or 24V battery system voltage. Connect the battery +Ve cable to the
battery terminal. Connect the battery -Ve cable to battery -Ve terminal.
Step 4
Make the Inverter's AC connections
: Make sure there is no LIVE and Neutral Swap in the
Inverter's input and output. Connect the Mains Input of the Inverter to REhub. After REhub screens
shows that the battery system voltage is detected, connect the AC 3 Pin plug to Mains supply. Your
REhub installation is complete. Close the L plate once the system working is verified on the display
screen. WAIT till you see REhub switching off the MAINS input to the Inverter and the Inverter
indicates that it is in back-up mode.

Make sure that LINE and Neutral wiring in
existing Inverter matches the Mains / house
wiring. Connect the Inverter Mains to REhub
and REhub to Mains input. Wait and confirm
that REhub switches off the Mains input to the
