Wasn't quite what I was expecting. No circuit diagram or schematic of what the change is suppose to achieve. But I was hoping for one controller - unmodified and one controller modified and the two run under identical circumstances to SHOW what the change achieves. Interesting concept though, I will have to search for videos that does this modification but with tests and results.
Dude please explain more in the description or in the videos. To me it looked like you removed the load transistors model them to process solar charge and put identical transistors back on the load or are they different and just happen to be the same size. How to then reprogram the board to allow override. Those are 75A each Trying to learn wtf you're doing but would help if you gave more info. So theybuse the same board for different models I figure. It reminded me of the perpetual energy videos for some reason. I'll keep watching though.
You do NOT melt the solder with the iron. You heat the parts where they meet until they are hot enough to melt the solder. I saw at least two cold solder joints that WILL cause problems in the future. Good soldering is important if you want the device to last.
no controlador pwm azuzinho de 10 ah,adicionei mais dois Mosfet zj70n78 ao circuito dele melhorou um pouco numa placa solar de 150 watts pra carregar 3 baterias automotiva de 60 ah e uma de 48 ah em paralelo somando a amperagem pra manter um sistema off grid em 12 v.
I have the same chargers myself. Different brand but really the same thing. The one problem I have eith all of them is that they discharge the battery more than they can charge when using panels smaller than 20W in the winter.
Put blocking diode in the positive wire of the solar panel to prevent the current from the battery to return to the panel. Cheers!!! Hope my comment is not too late .
I've got a similar charge controller and it gets very hot even when the solar is only 1 amp! I opened it up to look and it was clear one of the MOSFETs was overheating as the thermal tape was a bit bubbly. The soldering looks ok on the back of the board but the pins push through to the other side and only some of them are soldered at all? The hot MOSFET has a dry joint on that side so probably the cause of the problem. I can resolder that but shouldn't all the other pins be soldered too? It's a double layer board. Any advice would be appreciated. Thanks.
I need advice, please: I have a 455W solar panel...I bought BOTH Mppt and Pmw controllers from China (100A)...When I connect the solar panel, the controllers don't accept the panel? The controller shuts down soon?! Thank you very much
P75NF75 ( Transistor breakdown ) Type of Transistor: MOSFET Type of Control Channel: N -Channel Maximum Power Dissipation (Pd): 300 W Maximum Drain-Source Voltage |Vds|: 75 V Maximum Gate-Source Voltage |Vgs|: 20 V Maximum Gate-Threshold Voltage |Vgs(th)|: 4 V Maximum Drain Current |Id|: 80 A Maximum Junction Temperature (Tj): 175 °C Total Gate Charge (Qg): 117 nC Rise Time (tr): 100 nS Drain-Source Capacitance (Cd): 730 pF Maximum Drain-Source On-State Resistance (Rds): 0.011 Ohm NOTE: It's still PWM and can only do so much. If the backing plate is NOT Metal you'll get tons heat build up. I assume you can safely go over the basic wattage tolerances. example 12v 120 watt ( 10 amp ) PV to under 12v 240 watt ( 20 amp ) solar PV.
Hope you figured it out . 200 ah. Potentially 100ah if there acid.. hope you have more than one scc. If you have the panels you could be using the excess during the day and still be charged up for the night ..
My solar pannel gives 19-20 volt to the controller and using 12v lead acid battery...but there is 16.8v output from load during day time. I need only 12-13v how to reduce voltage from my charge controller...plz reply😢
use dc to dc step down buck converter,, put in scc wire going to scc, scc-buck converter-scc, then adjust the voltage output of buck converter module into the volts you want
Your soldering was giving me a migraine. Dude you really need to watch a few RUclips vids on soldering. Also, at the very least, please explain why you did this work .
আপনি যে কন্ট্রোলারটি নতুন নিয়েছেন, সেখানে হাই কাট কাজ না করলেও লো কাট কাজ করছে, এটা সম্ভবত কিছু সেটিংস বা সংযোগ সমস্যা হতে পারে। নিচে কিছু পদক্ষেপ দেওয়া হল যা আপনি চেষ্টা করতে পারেন: সেটিংস চেক করুন: কন্ট্রোলারের হাই কাট সেটিং ঠিকভাবে সেট করা হয়েছে কিনা তা যাচাই করুন। কখনও কখনও সঠিক ফ্রিকোয়েন্সি রেঞ্জ বা গেইন লেভেল সঠিকভাবে সেট না হলে হাই কাট কাজ নাও করতে পারে। কেবল সংযোগ চেক করুন: কন্ট্রোলারের ইনপুট এবং আউটপুট কেবলগুলো ঠিকভাবে সংযুক্ত আছে কিনা তা নিশ্চিত করুন। কোনো ড্যামেজ বা লুজ কেবলও এই ধরনের সমস্যা সৃষ্টি করতে পারে। ডিভাইস রিস্টার্ট করুন: মাঝে মাঝে ছোটখাটো সমস্যা একবার রিস্টার্ট দিলে ঠিক হয়ে যায়। কন্ট্রোলারটি বন্ধ করে আবার চালু করুন। ফার্মওয়্যার আপডেট: কন্ট্রোলারটির ফার্মওয়্যার আপডেট করতে হবে কিনা তা চেক করুন, কারণ কখনও কখনও সফটওয়্যার আপডেটের মাধ্যমে সমস্যা সমাধান হয়ে থাকে। হাই কাট ফিল্টার চেক করুন: হাই কাট ফিল্টার যদি খুব বেশি কম ফ্রিকোয়েন্সিতে সেট করা থাকে, তাহলে এটি কার্যকরী হবে না। সঠিক মানে সেট করা গুরুত্বপূর্ণ। এগুলো চেষ্টা করে দেখুন, আশা করি সমস্যা সমাধান হবে!

Watching this "soldering" was triggering me like crazy, it's like "No, no, no, not like that !!!" 😡😡
author is in a histerical hurry, and not using any flux - hence all the cold soldering. such quick-doers do pay times more for same.
Exellence video, Thanks for sharing and wishing all and thanks so much sir for this knowledge
If u can't have Mosfet, using NPN transistor.
Yeah Sir quite impressive for humanity
Lots of detail- you must be an expert! Thanks for sharing and wishing all the very best! Peace! 😸😸🙏🙏👍👍
Can I replace P75NF75 MOSFET for all the moseft in this type of charger controller.

So !!! what has change from the original compared to your upgrades?
I have the same chargers myself. Different brand but really the same thing. The one problem I have eith all of them is that they discharge the battery more than they can charge when using panels smaller than 20W in the winter.

As a layman, I ask what will be better than getting 2 new mosfets?

What mosfet did you use for the lamp? IRF4110?

Could you find a way to turn on/off a 100a solid state relay with this controller?
Soldering iron ka beat kaun sa use karte ho aap
How is change? How Mofet you use?
I need to know i have a 12v 200ah battery wth this blue control is it fine to use with this.
Hope you figured it out . 200 ah. Potentially 100ah if there acid.. hope you have more than one scc. If you have the panels you could be using the excess during the day and still be charged up for the night ..

how much more power will this make it?

Why no have inductor? Do you know the topology?
Im also trying to find the answer of this question.

Fantastic job.
Have a wonderful weekend! ♥
no written comparison - useles video. author could write some line at end for clarify.
How to modify it to higher voltage so I can run from 85V panel?
Your soldering was giving me a migraine. Dude you really need to watch a few RUclips vids on soldering. Also, at the very least, please explain why you did this work .

ভাই আমার সেম এই কোন্ট্রলার নতুন নিয়েছি হাই কাট কাজ করে না কিন্তু লো কাট কাজ করে,, এখন কি করা জায়
আপনি যে কন্ট্রোলারটি নতুন নিয়েছেন, সেখানে হাই কাট কাজ না করলেও লো কাট কাজ করছে, এটা সম্ভবত কিছু সেটিংস বা সংযোগ সমস্যা হতে পারে। নিচে কিছু পদক্ষেপ দেওয়া হল যা আপনি চেষ্টা করতে পারেন:
সেটিংস চেক করুন: কন্ট্রোলারের হাই কাট সেটিং ঠিকভাবে সেট করা হয়েছে কিনা তা যাচাই করুন। কখনও কখনও সঠিক ফ্রিকোয়েন্সি রেঞ্জ বা গেইন লেভেল সঠিকভাবে সেট না হলে হাই কাট কাজ নাও করতে পারে।
কেবল সংযোগ চেক করুন: কন্ট্রোলারের ইনপুট এবং আউটপুট কেবলগুলো ঠিকভাবে সংযুক্ত আছে কিনা তা নিশ্চিত করুন। কোনো ড্যামেজ বা লুজ কেবলও এই ধরনের সমস্যা সৃষ্টি করতে পারে।
ডিভাইস রিস্টার্ট করুন: মাঝে মাঝে ছোটখাটো সমস্যা একবার রিস্টার্ট দিলে ঠিক হয়ে যায়। কন্ট্রোলারটি বন্ধ করে আবার চালু করুন।
ফার্মওয়্যার আপডেট: কন্ট্রোলারটির ফার্মওয়্যার আপডেট করতে হবে কিনা তা চেক করুন, কারণ কখনও কখনও সফটওয়্যার আপডেটের মাধ্যমে সমস্যা সমাধান হয়ে থাকে।
হাই কাট ফিল্টার চেক করুন: হাই কাট ফিল্টার যদি খুব বেশি কম ফ্রিকোয়েন্সিতে সেট করা থাকে, তাহলে এটি কার্যকরী হবে না। সঠিক মানে সেট করা গুরুত্বপূর্ণ।
এগুলো চেষ্টা করে দেখুন, আশা করি সমস্যা সমাধান হবে!
