A clean 10A Solar Panel Controller?
« on: August 12, 2022, 08:29:54 AM »

I'm looking for recommendations on a RFI clean 10A solar panel charge controller. Not interested in a controller that dithers the PWM so the manufacturer can pass CE mark testing via QP'ing the conducted emissions.
I had to break into my EMC grab bag at field day this year.
Thanks,

Genasun is the only manufacture who makes certified quite controllers. Be sure to pick a Marine model as they are made specifically for. NAV/COM.

Do they have a US based outlet?

Sure, just about any tree hugger store that sells solar equipment in the USA has them. Even have them on Amazon and Flea Bay. You are looking for a GV10 for Pb batteries. They also make them for Lithium, same model just different algorithm

Try Alt-E store, for $90 . https://www.altestore.com/store/charge-controllers/solar-charge-controllers/mppt-solar-charge-controllers/genasun-gv-10-pb-12v-105a-mppt-controller-for-12v-lead-acid-batteries-p10626/

Any green mafia member can get you one.

These guys purport low conducted EMI MPPT controllers:

   I will strongly second this suggestion.   Our club's  solar powered comm trailer had strong RFI from the original controller.   We found and ordered a couple of the diysolarforu  controllers to replace.   We made comprehensive tests for RFI from these new controllers and there was none.   My personal unit measured the same.  They are truly no RFI controllers.

GENASUN---the only way to fly!  I got mine on eBay from a lady in Pittsburg, CA if that helps.

This is not rocket science.

I have a 100% QRO solar station out here in the NM desert. The MPPT charge controllers have a bit lower EMI emission foot print but the efficiency is about 3% lower than normal (cheep) charge controllers.

All you have to do to clean up the emissions on the charge controller  is connect a .1uF cap from the plus and minus leads on the input and output connections to frame ground. In addition run the plus and minus, input and output leads through a type 31 mix, 240 toroid next to the controller with about 8 turns of both leads.

My solar system (4ea. 300 watt panels) charges 600 amps of 28 volts storage wet cells which powers a AMIS 4000 watt split phase inverter for the amp and the air conditioner. The rest of the station, lightning and computers are all 12 volt.

My noise level is S zero. This is on 20, 40 and 80 meters.

The ZAMP PWM 40A and 15A are known to be very quiet, used for portable operating in the desert where background noise is S0.

I have one of their smaller units and with two of their $5 supplied chokes and it seems to have zero RFI.

Another vote for Rob at diysolarforu.com .   I have one of his Sol Buck/Boost MPPT controllers and it is EMI quiet with the addition of a couple of toroids that he supplies.

Rob is very knowledgeable and responsive to questions on all things solar.
