Difference between a PWM & MPPT Solar Controller (Real Life Example)

Показать описание

This video describes the difference between a PWM & MPPT Solar Controller with a practical demonstration. The practical demonstration shows an EPEVER 20A PWM and a 20A MPPT connected to the same model solar panels and batteries in order show a real life example of the difference in performance between the two.

Basically...if you're building a large solar system, get a mppt charge controller. For a small 12v system, get a pwm charge controller and a extra solar panel for better results. Nice video. Brilliant explanation of how both controller work.

This Video Explains in very simple layman's terms why an MPPT is the better option. Along with a more detailed explanation. He does this in just over 5 mins. BRILLIANT > thank You so much . If this was an American Guy or Shiela (LOL) explaining, we would probably be 30 mins plus. Thanks Bruce

24 volt system changes the whole equation, 31.8 volt panels match very well to pwm for 28-30 volt charging...simplicity and cost effective. MPPT is good for voltage matching, that's the main plus ...thanks for the demo⚡

let me narrow this down. for large solar farm go with the MPPT with little to no shading panels will be wired in series. for a small off grid setup go with the PWM with some shading panels will be wired in parallel.

This is true practical demo which i was looking for. Thanks

Great explanation, really helps newcomers like me. Cheers from Brazil

On my small system of 240 watts, I have been using a PWM for 15 years now and it has worked very well except for the slightly incorrect voltage and amperage displayed. I will be upgrading to an MPPT early next year and adding more panels. Thanks for the video and greetings from sunny Jamaica.

Based on this experiment, I will not use high voltage panels arrangement with pwm controller.
Thanks for the information

kudos for actually fusing (breakers/interrupters) on your lines.

Hey, in the video u refer to the other test between mppt and pwm but with 12V panels. Is this video no longer available?
Thx in advance

yoandre

For small systems PWM is adequate. If you want more amps from PWM add another solar panel to compensate.

jeoffer

26W from PWM in this example. If you use 24V battery, it would be 52W, because from MPP down, power is almost linear. Basically no difference between PWM and MPPT, or maybe 2Watts would be with those panels and 24V battery.

How many Amp .breaker needed for for 4 200watt solar panel.

I have a mppt eleven tracer and the volts are high but the amps is really low any suggestions?

Hey mate. Question on the breakers in your videos. I'm putting a Noark Switch MCB DC 2 Pole 40A 360V non-polarised breaker on my camper van. Same model as you have here, a Ex9BP-N. Do I just put the 8 B&S - and + from the solar panel into the bottom of the Noark, (one each side ie. one to each screw) then out the top (load side) then connect the MPPT solar in via Anderson plugs like you wired up here?. (I want to protect MPPT and be able to isolate panels with the Ex9BP-N). I'm thinking of adding Andersons 50a connectors to the breaker wiring too, both ends so will have permanent Anderson connectors each side (input and output) of the breaker. Any issues in having Anderson connectors attached to the breaker wiring? reason, my MPPT then can be unplugged and taken out into the portable solar when not taking the camper trailer with me, example: going to the beach and just taking fridge, solar panels and battery, and of course the mppt. Also, last one, why the different breaker with red switch lever and not to same breakers ie. both Ex9BP-N's? Cheers!
