Add Solar to your existing Inverter with REhub MPPT Eco in these easy steps
REhub controls the Mains input of the Inverter to utilize Solar when available
Loads are powered using Solar and Batteries during the day time. The mains input to the Inverter is switched off - therefore, it is preferable that the Inverter is a pure Sine wave inverter (Appliances like Fans produce a hum with square wave input - and with REhub the Inverter is 'Inverting' DC to AC through the day) .
REhub MPPT Eco is for 12V and 24V battery systems. It auto detects the battery system voltage and converts the extracted Solar power at the maximum power point voltage to the battery voltage.
REhub MPPT Eco allows you to work with 12V/24V PV panels even in an all series arrangement reducing system costs
[1] REhub MPPT Eco has a continuous rated output of 25A. Like the other charge controllers in the REhub family (Namely REhub PWM and REhub MPPT ), REhub MPPT Eco safely limits the output to the rated current even if a larger PV array is connected to the unit. Because the peak output from Solar panels are available only on certain days, using a larger panel results in higher energy generated everyday.
[2] REhub MPPT supports array Voc of 90V. This has potential to reduce the system costs. PV panels are available in 36 Cell (called 12V panels) , 60 Cell (typ Solar PV panels used in MW plants) and 72 Cell (called 24V panels). Typically, the cost per watt of a 36 Cell panel is more compared to a 60 cell panel or a 72 cell panel. With PWM chargers, it is imperative to match the panel voltage with the battery system Voltage and therefore you are constrained to use 36 Cell panel with 12V battery system and 72 Cell panel with 24V battery system. With REhub MPPT Eco however, you can use 36 cell / 60 cell or 72 cell panel even with 12V system.
[3] With REhub MPPT Eco you can lower the wiring costs because you are operating at higher voltage at the input. You can even wire the panels in an all series arrangement and eliminate the need for array junction boxes in your installation.
REhub MPPT Eco comes with a AC socket and a meter long cable with 3 pin plug for the Inverter's Main's connection unlike some other ' Retrofit' units or 'Converters'. . Wiring is simple , easy and safe. Just make sure that array Voc is less than 90V. REhub MPPT Eco is protected against PV and Battery reverse polarities.
