Yesterday I received a call from a system integrator – who has been installing solar systems using PWM charge controllers and is looking at switching to MPPT charger. He has an experimental set up with a 200 AH batteries, 48V, 2500 Wp Solar panels : 250 Wp X 10 nos ,…
Read MoreThis is another very commonly asked question.Here are some guidelines to determine the size of install in India. Money as a constraint : If Rooftop schemes with reverse or net metering is available in your locality ( not unless you are in Gandhinagar for example http://mnre.gov.in/file-manager/UserFiles/presentations-pwc-workshop-06092012/GEDA.pdf) install as much as you have…
Read MoreAs we interact with a variety of different solar system installers, we have got this question repeatedly – does MPPT make sense in Indian conditions. The implied question is – MPPT controllers cost more than the PWM counterparts – is it worth the while to add this cost to the…
Read MoreREhub 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…
