EPEVER 60A MPPT Charge Controller 48V 36V 24V 12V Auto, 60 amp Negative Ground Solar Controller MPPT Max 150V Input fit for Litium Sealed (AGM) Gel Flooded User Battery

Mine is the 200VDC/100AMP one and is connected to a 4-parrellel strings of 4 series 72 cell panels. 295wp/cell each. I've put 1.6megawatt through it. the battery voltages are easy to setup for lithium batteries. the RS485 assesories allows me to save the data to PC with the eLOG01 box (sold separately.) The heat sink does get warm when its sunny so I have it mounted to a steel backing plate, fans would help. the MT50 readout is great for monitering.there is not really a good way to read data out into a web-based remote app. the Bluetooth and wifi are only good for nearby communication. otherwise this is a great item. I'll be buying another when I expand my system.

I have had this installed on a 1k solar array that feeds power to an off grid/on grid work shop. It power all my LED lights and chargers off 2 deep cycle battery's. I would by again and it works perfect. I did get the software to work on a laptop back in 2019 and it was crappy. Unless they updated it do not buy this thinking the software is amazing because it was hard to set up and kind of useless once I did. But the 100 amp unit is rock solid. I never even think about it..... the thing just works. And that's how i like it.

Been using the older style 40 amp.12/24. I'm up graded my voltage to 48. I bought the 12/48v CC kit..I love how it covers any of the; voltageI love these controllers.Best units for the money. IMO....Just as good as an outback HALF THE PRICE.I Like the dry contact option that are in this unit new 50 amp unit. Many options for that. Load control is easy to use. I have the MT-50 on both which is a must unless your plugging the unit into a lap top or PC for the settings which are more detailed doing that way. The MT 50 pretty much gives all the information you need with a nice bright back light look 9. The temp sensor is another great feature. I bought the whole kit. Very easy to install unless your not savoy enough to do so.I will be using upto 80% if it input rating to keep it lasting. The older 40 a CC will be out back in commission for a second solar array fyim a different direction. INot sure yet if both CC can communicate or have an option to do so yet but not a great concern.The older unit has its own built in contactor for load control..The newer one you have to buy a good relay, set the parimutets in the load control settings and provide a passing voltage thru the dry contacts on the new model. Be doo to use it for a lie volt disconnect and it with a grid tie inverter fornuhht time use. Use the batteries to feed the GTI and the load setting to cut off battery power to the inverter. Many options in thatpartSo far so good. Highly recommend.

Only reason I am giving 4 instead of 5 stars is due to the less than clear instructions. The most difficult aspect of the install was plugging in the battery temperature sensor (darn hard to get at). This controller is a great value, especially considering the remote is included. Granted had to purchase a longer cable so the MT50 could mount over my Magnum's remote. Ditched the MT50 base plate and used a hole saw for a very clean installation. With the remotes side by side I have noted a slight difference in the displayed parameters. With the voltage less than a 1/4 volt off confirmed by my who cares. This controller is a workhorse working over time to keep the state of charge on my 4 6-volt flooded batteries topped off from my 610 watts of panels. Only real con is no easy way to reprogram controller for my planned update to Lithium Ion batteries. EPEVER has several instructional videos on you tube I hope will help with this. Buy one both you and you wallet will like it.Edit: Updated my 4 6-volt FLA batteries with 4 100 Ah Lithium (LFP) batteries. Reprogramming the controller to charge them was easy. So far has been working great the last 3 weeks.

i have 5 200 wat solar panels on top of my garage with #10 100 amp sealed amg battery's,, this 100 amp ep ever pro mppt charge controller seems great we live in the north so i have two heat the cabinet two 60 two keep the battery's warm,,,, seems good,, i cant wait two use the power,,,,good product the service seems hit or miss,,, i have asked questions and never had them answered ,,,, so time will tell... with a 5000 watt modified inverter we will have two see what happens ..
