Inverter Connection
The Mains input LIVE of the Inverter is controlled by REhub. Disconnect the Mains to Inverter
connection plug and connect to the REhub Socket [7]. Connect MAINS input cable [6] to Mains Live
input. The rated Load current of the connected Inverter MUST be less than 60A. Keep the Inverter
in Away/ Off mode till you are ready for the Final Power UP.
6 Powering Up
Connecting the battery terminals will energize and start the unit. Do this last. Before energizing
the equipment, recheck the polarity and the connections. Keep the MAINS MCB switched off.
A. Connecting the battery: On the BAT+Ve and BAT-Ve terminals. Check the battery terminal
Voltage. Make sure you have chosen the right Battery system Voltage for the REhub. A 12V battery
system will have Voltage between 10.8V to 14V. A 24V battery is likely to have a Voltage between
22V and 28V. On first time power on REhub will go to Auto Detect Mode
B. Completing the PV+ and PV - connections.
Check the Voltage between PV+ and PV- wires before closing the PV -ve. You will get a Voltage
approximately equal to the open circuit voltage of the array.
Note if the installation is being done in the night you will not get the Voc value but likely to get a
Voltage which is much lesser.
C. Complete the Battery GND to Inverter connections and the AC live from Mains
connection.
Switch on the AC MCB. Put the Inverter to normal mode.
Take care not to Swap Solar PV and Battery connections. The unit is not protected for such a
Swap. The unit will not Power UP if Battery is connected in Reverse Polarity. If PV Polarity is
swapped, the unit will show Solar as 'LOW'.
