EPEVER MPPT Charge Controller 30A, Solar Controller 100V PV Negative Grounded Solar Panel Regulator 12V/24V Auto Tracer 3210AN + Meter MT-50 + TS-R for Gel Sealed Flooded Lithium Battery

I own 3 EPEver Charge Controllers. A 20, 30 and 40 amp version. I've used this 30 amp version to build a portable charge controller in a box. I take it out in the field with me camping or star gazing and together with my extra solar panels I can charge up any of my batteries to prepare for the night time fun. Just like the other 2 units this thing is a solid performer. I have the 20 amp which is in my 4-Runner and has been running non-stop now for over 2 years without issue. It charges a 100AH 12v Wieze LiFiPo4 battery powering an AI Astro freezer. The 30 amp unit performed perfectly on our last trip providing supplemental charge to our camper system which has 2 12v 200AH batteries. Using this unit and 3 100watt panels which I could move around to follow the sun through the breaks in the trees we were able to keep everything charged without the need of the generator. EPEver keeps all my gear up and running. Solid unit, well built and durable. Consider it's little brother the 20amp is on the 4-runner being subjected to all the vibrations and bouncing of an off and on road vehicle. When I need more power in a small package I will always look to EPEver.

I just purchased a new RV and needed to add solar charging as I had installed on my old RV. I was a little skeptical when I purchased this Solar Charge controller since I usually try to stay with US built products. I most always get better service and quality from US companies and a better warranty. After looking at the cost differences between the China built product and what I paid for my first solar controller "US product" I figured what the heck! I'll give it a try. And I gotta tell ya, I am impressed with this MPPT 30 amp charger! I roof installed the exact same two 7 year old 140 watt solar panels. I actually moved the same (3) 105 amp hour deep cycle batteries I had just purchase for the old RV about 6 months ago to the new RV.(Cheap sob's) only put 1 small deep cycle in the new RV. So I am pretty much comparing apples to apples except for new wiring with the same size 8awg wiring I had in the old rig. The only major component changed was the Solar charge controller as the old one was not designed to be located with a separate monitoring panel and I could not find an ideal location for it. Long story short this EP Ever 30 amp MPPT charge controller charges better than the old one with the same solar panels. The old controller was also and MPPT controller but the best I had ever seen was about 8.5 amps on very low batteries. I have seen as much as 12 amps charging with this new controller with the same (7 year old panels). It steps down through the charge process just as it should and if left on it maintains the batteries properly and also sleeps and wakes up properly once the sun rises just as it should. I do a ton of off grid backwoods or desert camping and as long as it holds up? I will be a happy camper watching the nightly news or a movie without firing up the genny... :-) Only suggestion is make sure you get the NEGATIVE Ground model if you are in the US...

June 2, 2020 Purchase date: Item did what it was supposed to do. Easy to install. Recommend attaching a small maintenance battery (12ah) with battery switch so the main battery bank can be disconnected for maintenance or relocation. This way the system can remain fully connected (as require) and avoids the need to disconnect solar panel wires at charge controller point. May 2021: weak and unimpressive wire terminal connecting points on unit. Problem occurred just before one year mark: One of the terminals, specifically the negative connector from the solar panels, failed. The inner screw mechanism/clamp mechanism failed. It is unknown how this occurred. Discovered when power zeroed out from panels. During a maintenance inspection the wire was observed still inside, but not fully connected to the terminal. Given the impression that it was still connected from a distance official inspection. Generally, terminal connecting points On charge controllers have not been very robust on a number of units, including this one. Renogy, had very cheap plasticky look and feel, which also failed. Returned that one got the Epever Tracer 3210 AN here. Other complaints on the solar charger connecting points having three holes are too small, and are not easily work with other wiring going down stream away from the controller. This connecting point is no different. It appears that the inner clamping mechanism failed. This is complicated even more because you cannot see this connection embedded inside of the device. So you have to blindly shove a strict end of your wire into a hole hoping that the clamp in mechanism Titans around it for you over tighten the mechanism because it past the end of the wire. Giving you false sense of security. Abetter design would be to allow the user to see the entire terminal mechanism area. Which can then be covered with a separate cover as part of the unit. This weekend is your can observe the terminal connecting point watching the small clamping force rules lol come together while connecting wire. At this point the vendor will be contacted, or the manufacturer, requesting a replacement for a proposed workaround for this problem. He posted photographs here show an improvised solution for now, using a small alligator clamps to reach inside the small holes to complete the connection while I work around or replacement is sought. if vendor or the manufacturer does not recognize this repair or replace a request. A particular workaround would be to open up the unit and solder in an extension piece of wire bring the connection and the wire outside of the box for connecting to the rest of the wiring to the system.

Upgrades to a LifePo4 bank and added more solar panels. Needed a larger controlller and as my previous also was a Epever and worked for years without problems I opted for this one again. Also these newer versions have a LiFePo4 setting.

This is a great unit. I installed in my pop up camper, connected it to 2 windynation 100 watt panels and my 100ah Renogy AGM battery. On a cleasr sunny day last week it was showing 12 amps and 16volts out of the panels and it was charging my battery at 14.2v. Very happy so far. Side note: The software is basically usless, you dont need it. The remote shows the same data.

I have installed over 180 Mobil solar systems. I have had the opportunity to use most of the brands out there and by far when asked I always recommend the e-pever controllers. Make sure to order the MT-50 programming display. Many times you can find a bundled offer that includes the MT-50 and a temp. probe. I have never had an issue with an e-pever controller, ever! Money spent on these controllers is money well spent.

Wow this unit is awsome! Was only getting about 4 to 5 amps out of my old pwm charger with two 100 watt windy nation panels. Not quite enough to keep you going dry camping unless you were in full sun all the time. I ordered this unit and wow! 10 to 11 amps in cool sunlight. It also regulates amazingly well. The minute you get a load it kicks up to fill amperage, the minute the batteries are up to around 13.5 volts it starts to scale back to around 1.5 to 1 amp. Also the remote meter is awsome! No more going outside to check what's going on, this unit gives you all the readings and you can also control the unit from the remote. I would have given it a full five stars but the remote cable is way too short. Just buy a normal Ethernet cable and it will work. All in all I highly recommend this unit!

This is an OK unit. It is however an example of a product designed by people who do not use it. The most important question in the mind of an offgrid user is "Did my batteries get charged today?" This would be very easy to display. Also the Bulk, Absorb and Float stages need to be indicated on the display. This unit did none of these. However as an MPPT controller it works fine.

very good

load connection not for inverter what is it good for.
