Note: Do not use a washer between the Battery lugs and the terminal [3]. Allow direct

contact of the lugs to the terminals to reduce resistance.

4.5 Inverter Connection

REhub is meant to add SAFE Solar PV to existing Inverters. 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 100A. Keep the Inverter

in Away/ Off mode till you are ready for the Final Power UP

5 Screens and indications

REhub has a 16X 2 LCD screen and three LED indicators. The display scrolls through various

screens and is a useful indicator for details on what is happening with the charger. The LED

The Battery status screen shows the Net Amps delivered to the batteries and the battery Voltage.

By default, the maximum +Ve current to the batteries is set to 18A. A negative value indicates that

the Load is higher than Solar, and the Amps shown in being drawn from the batteries. The Solar

output screen shows the Output Amps and the instantaneous Power generated. The external

temperature value is used for Temperature compensated battery charging. This value is shown only

of the external temperature sensor is connected to the unit.

The 'Energy' screen shows the Cumulative energy generated by Solar PV.
