How a good MPPT charge controller (e.g. REhub) reduces system costs

Karthik 1 Comment

REhub  is based on an high efficiency MPPT charge controller with the ability to accept a wide input MPPT range ( e.g 17 – 65 V for a 12V battery system).
System_integrators can use this to their advantage by
a) Selecting PV panels that are mass produced and therefore of lower cost. E.g to set up a 400Wp installation – using 4 X 100 Wp panels cost more than using 2 X 200 Wp panels. Yes, the 100 Wp panels are selected in installations today because of the need to match the PV panel output voltage to that of the battery system voltage – not needed any more with REhub.
b) Wire the panels in an all series arrangement. Typical Voltage at the Maximum Power point ( Vmpp ) for a 200 Wp , 60 Cell panel is about 30V. Wired in series the combined voltage is at 60Vmpp. REhub converts the input power at Vmpp to Vbatt ( the battery voltage) efficiently. The higher input voltage would mean that wiring costs are lesser compared to having all panels in parallel and operating at 17 V.
c) Lesser civil work and structurals on the roof top. Lesser panels : lesser cost .
