MPPT Charge Controller 60 amp 12V/24V Auto, 60A Solar Panel Charge Regulator with Blacklight LCD Display Max 100V for Lead-Acid Sealed Gel AGM Flooded Lithium Battery

Very nice product.Very simple so anybody can hookup and user friendly.Being completely automated knowing what batteries you connected with automaticallyNo programming to doCompletely automatically done..

Para un sistema operativo solar pequeño, lo súper recomiendo, un equipo con materiales sumamente de buena calidad, buen rendimiento.

NO CUSTOMER SERVICE AT ALL ! The first one I bought had a bad LED screen, they wouldn't swap it, no warranty offered. It took 8 hours of computer searching just to find the seller who told me to go stick it. Even with 2 of these installed there is no way to tell if I have them set correctly BECAUSE THERE IS NO PRODUCT SUPPORT WHAT SO EVER and Amazon wouldn't know a electrical circuit from a circuit city.

The description when I purchased this item on Feb 27, 2020 was: MPPT Solar Charge Controller, OOYCYOO 60amp Solar Panel Charging Battery Regulator 60A 12V/24V Auto Work, with LCD Display Max 100V, 780W/1560W Input for Lead-Acid Battery, with Load Timer SettingThe description of this item as of Jul 4, 2021 is: OOYCYOO MPPT Charge Controller 40 amp, 12V 24V Auto 40A Solar Panel Charge Regulator, Max 100V Input with LCD Display for Lead-Acid Sealed Gel AGM Flooded Lithium Battery (MPPT-40A)The 60 amp version is no longer available for sale on this particular page.The max amp output for my 12V system that I have seen thus far was only 36 amps (in direct sunlight with no clouds). My solar panels are supposed to be able to generate 53 amps at 14V. (Which is why I purchased the 60 amp version.)The manual that came with the item is translated from Chinese and difficult to understand in English.I am not sure why I am not getting over 40 amps. The SOLAR MPPT unit I have looks identical to the pictures on this product. How do I know which version of this item I actually received?

Update for 1 June 2021: unfortunately, today I lost the controller that is pictured. Possibly due to the solar panel generating more electricity than the controller could handle. It was a quick 10 minute replacement with a spare. Overall I remain highly satisfied with these controllers and plan to continue using them in the future.SET-UP: I built 2 separate solar systems using 300watt Solar World panels, however, I made a mistake in trying to run these with simpler Pulse Width Modulation (PWM) 30amp controllers and was only harvesting half of the available power.PRO: I was pleasantly surprised that this is a true Maximum Power Point Tracking (MPPT) solar controller. I replaced the PWM controllers with these PowMr MPPTs and gained 500-700 watts in daily production. Each panel is now producing an average of 1050 watts per day versus their previous 500 watts per day. Even with 600 watts (2 x 300watt panels) of power going in, they do not get extremely hot, so the lack of active cooling does not seem to hinder power production. The controllers are easy to configure since they do not have any major features and for the roughly $100 price, this is a good deal compared to other MPPT controllers. Two USB ports are a nice extra feature.CON: as with other PowMr solar controllers, these do not tell you how many amps it creates on a daily basis, so you will have to use a separate meter such as the Bayite monitor (as show in picture #1). It comes with a Comm Port, but I have yet to find a sutaible monitor. Both Amazon sellers (PowMr and OOYCYOO) overstate the maximum handling capacity of the controllers. At 12 volts, max capacity is 720 watts and at 24 volts, max capacity is 1440 watts. Make sure to design your system with enough overhead to allow for increased wattage/amperage on really sunny or cool days, as solar panels WILL generate more power than advertised. Finally, reliability is unknown.

Purchased in 2019, still functioning in 2024, only reason it’s not 1 star. THIS IS A 40 AMP MPPT!! It limits itself to 40 amps! Unfortunately I didn’t have enough panels to exceed 40 amps until recently. Adding more panels causes the PV voltage to rise but no more current will flow. Grabbed an EPEVER 30a and split my panels between both controllers, now I’m getting a full 70 amps (confirmed this with external meter), so I know I had enough solar to reach its supposed 60 amp limit.

Not like I've tried a ton of charge controllers, but I've probably messed with about 6 or 7. I plugged this guy in and the lil fans started whirring, and i hoped they wouldn't do that constantly, but I think that was just a wake up thing. I doubt I'll juice this enough for them to come back on. It doesn't warm up with about 300W from solar coming in at least. The clear cover is actually kind cool, wish more products were like that, why not. The screen shows all of the monitoring details i need to know and makes sense. It also doesn't lag, I've seen some that lag when touch a button for like a second or 2. Every time I'm like, I KNOW the sun is on the panel. Then it changes.... It comes with a really long temperature sensor you plug into the bottom left. The cord is like 30 ft. long (or so). Don't really know why that's needed, but whatever. I don't think i can change it from Celsius, which is a bummer. The LEAST of my worries. So far it seems really efficient and powerful. My fav Charge Controller! I'll try and update if anything changes during use.

I owned a lot of controllers before. This one lasted me a long time so far. Thank you.
