I am putting together a solar array of 4 590W solar panels (https://www.renogy.com/products/renogy-bifacial-590-watt-n-type-monocrystalline-solar-panel). I’d prefer 2 controllers, each supporting 2 panels as the space it tight for adding more controllers. Can someone help me in sizing the correct Victron MPPT Solar Controllers for this setup?
Take a look at the MPPT calculator:
Thank you Matthias. I am a novice and tried using the calculator. In the drop down of the solar panels the panels I acquired are not present. So I selected the 550W panels. After putting in other information, the response I got was that no controllers were found.
You can also enter all parameters of your panel manually.
Please make a screenshot. I guess you entered something wrong.
Here is a picture:
I’m guessing that if I have 4 panels but want to have 2 controllers manage 2 panels each this is what I would put in. If I change Series to 1 and Strings to 4, same answer. But if I make Series 1 and Strings 3, I get an answer. Not sure if that is helpful
If you have 1 controller managing 2 panels is series, then series is 2 and number of strings is 1.
I have four 540 Wp solar modules in a 2s2p configuration connected to a single Smartsolar 150/45. It’s a great fit.
you wont find any match on the mppt calculator, your operating temperatures is wild.
-40 to 85 degrees Celsius.
Victron mppts are usually rated for -30 to 60 degrees Celsius
a 150/35 MPPT x2 should work for you.
Thank you
