How to repair solar charge controller 

these chargers (even though they are not MPPT) are not bad at all. For most small scale applications they are even pretty damn good actually. If you have one with a temp sensor even better... PWM charging has become the bad guy in recent years but in actual fact they are still very usefull. MPPT is very nice to be able to squeeze out every last little amp from your solar setup but in reality the added efficiency does not outweigh the massive cost differences. Only in very large solar setups (3-5kWpeak solar arrays) becomes a MPPT charger into it's own but for most peoples off grid cabin, shed, RV, remote equipement (like pumps in a well or a animal feed station of sorts) and most test setups involving 1-1.5kW of solar paneling you can go for the more budget friendly PWM charging. These guys as so cheap (but not crappy or badly made) you can have one on hand in case your current one fails for some reason. In most cases failure is because of heat. The internal electronics gets hot (obviously) and needs to get rid of the heat. The back panel is supposed to provide some heat sink but this proves insufficient. To remedy this you can for one replace the back panel with aluminum plate (a bit costly and a hassle to be honest) but more effectively you can employ two aluminum pan scrubbers and some long 2 inch screws and some plastic tubing to stand off the controller from it's mounting board with the scrubbers squeezed behind them providing some added heat sink. Especially the higher current ones can even benefit from a small pc fan (which can run on the 5V usb power available from the front of the controller) If you like a larger setup you can divide up your larger solar array electrically into 2-3 chunks (simply add the max. current at the panel's maximum power together (add about 25% for some safety margin) till you hit the maximum amperage the controller can handle) can handle (this example (30A) and connect them in parallel to the same battery(bank). This is a little known fact of electrical know how but it is a very sensible way of saving money and at the same time build in some redundancy into a possibly critical system (you know you don't want the well pump to cut out because your single charge controller stopped working and now your animals are without water or the veggie garden isn't been watered. A 30A controller like this one should be about to handle 3 common available 255 Wp panels in parallel. Do not put panels in series because most of them will over voltage the controller even at moderate sun/output. 3 in parallel should work and for every 10 A of rated current you can ad another in parallel.

Wish it was in English.. still appreciate and saved this video tho

Very nice 👌

👍useful me

Wow

Thank u

OK

Back ground music why playing, due to this not clear voice.

Bhai mujay load ka problem hy Wo nhi Kam krta hy

Sir charge controller par 1amp se 8amp tak upar nichay hota hai ye kya problem hai?seconds ke andar.

Mine has every icon lit black and 288. Test voltage in LCD and it's 3.## volts on all pins. Bought newer version that has smaller chip under LCD. That voltage is 1.## volts. I guess it should be 1v and not 3v on LCD?

Bhiya same problem mere sat bhi horaha ha

Usb connector ke jo ic oska nomber kia hai .bro

Which one is the bad one

Hi ,mere pas same vala solar charger he or usme solar ka positive socket chal raha he magar nagative me connect karne k bad display me kuch nahi aa raha magar negative wire ko battery k negative socket me laga te he to display on ho raha he.solution please.

What fuse you use ?

Sir iski bettry kuch din utaar di thi...lekin solar ki wire lagi rahi.. controller me..ab on nhi ho rha bettry lagai to

Sir mosfet kisi bhi site se koi bhi value nahi de raha na beep arahi hai

ভাই আমার সোলার কনট্রলারে আগে চার্জ যখন হত তখন ১৫.৯ দেখাত এখন ১৩.৭এর বেশি দেখায় না। এটার সমাধান কি।

Voltage not reducing in my solar controller why??

Mera complaint aya

Sir is me mosfet nob bta dijye

Mosfet number bolo bhai
