5.2 Mains Relay Operation Control: Switching Between Forced ON and

Auto Control.

REhub by default is in Auto control of the Mains Switch. REhub decides to switch off the

AC Mains input to the Inverter based on the availability of Solar energy and the state of

charge of the batteries. This forces the Inverter to use Solar energy to service the Loads.

Similarly, REhub auto restores the Mains connection when there is no Solar energy or the

state of charge of the batteries is below a set value. As a user you can decide to OVERRIDE

the decision of REhub by forcing REhub to keep the Mains switch ON. In ONAlwas (For On

Always) mode, REhub keeps the Mains ON at all times. In ON1Day (for ON One Day) mode,

REhub keeps REhub ON for the next 24 Hours and goes back automatically to Auto Mode

at the end of 24 Hours. These Override modes may be required in case the day is very

cloudy and Inverter is toggling frequently between using Solar and using the Mains to

power the load. Alternately, this may be required if heavy loads like Mixer-grinder is

connected to the lighting circuit supported by the Inverter. When running a Mixer, switch

to ONAlwas or ON1Day mode when power is available, to ensure the Inverter is not

delivering power from the batteries to the Mixer. Make sure to switch back to Auto when

the desired usage is completed.

Offgrid mode is a special mode in which the MAINS power is not used unless the battery

voltage goes very low. In Offgrid mode, REhub does not switch on the Mains input to the

Inverter even if Solar is not available. This mode is different from the Auto mode in the

way REhub switches on the Mains input to the Inverter. In Offgrid mode it automatically

switches on the Mains input only when the battery voltage reaches a set low value.

The different modes can be changed using the Mode button. Changing Mode using Mode Switch.

Press and hold the Mode select switch. The unit will display the mode it is in <Brackets>.

By default, the unit will be in Auto Mode. If you continue HOLDING the Mode select button

in pressed position, the next option moves to the bracketed position. Releasing the button

now will select that option. Continue pressing the switch and the display cycles through

the three options. REhub will move to the Mode that is in bracketed position when the

button is released.

When a Mode is selected you will get a confirmation screen indicating the mode in which

REhub is functioning now.
