REhub PWM is ideal for small Solar upgrade in homes

REhub_PWMREhub PWM  enables the addition of Solar PV to existing inverter back up solutions. The crucial difference between REhub MPPT and REhub PWM is in the way power is extracted from the Solar Panels. The technology used in REhub PWM is best suited for smaller Solar installations (typically about 200 Wp for a 12V system). REhub PWM connects to the Solar Panels, the existing batteries and the Inverter. REhub PWM charges the batteries and intelligently controls the use of the grid power for charging. The objective is to extend the back up hours to tide over long power cuts.


Prioritizing Solar : Auto and Manual modes

REhub PWM automatically determines when to switch over completely to using Solar energy and when to use the grid power. REhub PWM monitors the state of charge of the battery and the availability of Solar energy to make the decision to prioritize Solar energy.

When REhub PWM is put into 'Manual' mode the user effectively forces REhub PWM to keep the Mains connected to the Inverter. This mode is useful in case heavy loads which can trip the Inverter needs to be run.


View how much energy is being generated

align=noneREhub PWM has a display that allows the user to know the instantaneous Solar Power generated, the cumulative Solar energy extracted, the state of charge of the battery (Battery Voltage). The various system states including the availability of Grid power, Solar Power and if Solar energy is being used to power the loads is available.

 

Makes it easy to upgrade to Solar

REhub PWM makes it extremely simple to add Solar PV to a home back up. The Inverter's AC input plug is connected to REhub PWM (A socket is provided for this input) and REhub PWM has a cable with 3 pin plug for the Mains input. Once the Solar panel and Battery connections are made, the unit is ready for operation.


Auto detect 12/24 V

REhub can be connected to 12 V or 24 V battery system. REhub Auto detects the system battery voltage and starts charging the batteries if Solar energy is available.


Active protection

REhub is actively protected from Battery reverse polarity, PV reverse polarity and PV short.
