⚡ OOYCYOO MPPT Charge Controller K100A - 100 Amp Solar Panel Charge Regulator with LCD Display for 12V/24V Auto Battery Systems Review

Thanks guys, easy to connect, very clear information. I need a bank of 6 panels of 330w each running 24 volts in parallel for this charge controller to support the intensity then it deserves five stars.

This controller - I also have an external display - provides excellent information, has a large capacity for its price and is easy to install. There was a problem with the first one, but the seller quickly resolved it. While I cannot guarantee the accuracy of the values shown, they show changes that I expected.

Some parts of the manual are difficult to decipher, probably because of the translation. The device was easy to install. I will update the information as I gain experience. April 2021 Still working great, customer service was helpful and prompt as I wanted to add 2 more 100w panels for a total of 600w. + star!

Time for a Review. I bought this item about 6 months or 180 days ago, suddenly the MPPT started to discharge the load with fully charged batteries. Due to the stated 360-day guarantee, I therefore contacted the seller twice, but received no answer. Due to the irresponsibility of the seller, I do not recommend buying this product at all.

Everything about this controller is top notch! I'm using 6 x 300w panels but the max I've seen is around 1300-1400w. I think a couple of panels are actually 280w. I didn't really notice anything other than 36 amps from the panels, but it charges my 24v battery very well. Unfortunately this unit only supports 12/24v. It would be absolutely perfect if it had 36/24v options. 48 v

First I installed and connected the batteries. Worked for 2 days, then literally exploded. Flames within the block and filled my camper with smoke. Polarity was correct, inputs and outputs were underrated. The guide is more of an overview, but it's written so vaguely that it's unusable. the mobile home would burn down. when i slept Who knows. No fuses are blown and I'm backing up every load. He just glowed. Buyer Warning.

Mine worked 3 weeks and died. The seller did not respond to the replacement of the goods. From that moment on, I learned to pay attention to seller ratings and not just reviews. Check seller ratings before you buy cheap crap. I bought because of the price and now I need a new charge controller because there is no guarantee. Better to spend twice as much for a better device. Today I'm going to buy one of three different blocks to replace this one. I will call everyone first to find out how the…

Let's start with the positives - the 60A/100V version of this product is a true MPPT controller! For the price, this is the cheapest device on the market and I had high hopes based on the positive reviews from other buyers. Now the reason for the 1-star rating: The passive cooling system is not enough to keep the device cool under load, so it quickly heats up and freezes when charging. You can reset the device by disconnecting and reconnecting the batteries and then crossing your fingers in…

Update June 1, 2021: Unfortunately lost the controller shown in the photo today. Maybe it's because the solar panel is generating more power than the controller can handle. It was a quick 10 minute switch with a spare. Overall I am very happy with these controllers and plan to continue using them in the future. SETUP: I built 2 separate solar systems using Solar World's 300W modules, but I made the mistake of running them with a simpler PWM. (PWM) 30 amp controller and only collected half the…
