AIMS 30A MPPT Solar Charge Controller 12/24V SCC30AMPPT

I have not hooked up panels to it yet, only the battery and solar cable leads. But with the exception of the fairly minor annoyances noted below, I am sure the unit will work fine. Manual is a little lacking and they should send a magnifying glass with it to read. Look up the manual online which you can actually read. No explanation of how to press buttons to change settings. Through trail and error you can figure it out. One screen which shows watts, volts etc. (4 items on one screen) cannot be user set but rather sets itself when you hook up solar panels, but nowhere in manual does it mention that. Not everyone has a computer close by to hookup comm port to change settings.The clamps in the plastic housings on bottom that accept your power and solar wires seem flimsy. Be careful if you have to move controller with wires attached because it looks like the housings that the wires are in could possibly break, and the screw that tightens the battery and solar wires in the clamps is real small and takes a lot of force to hold in wires firmly so be careful not to strip phillips head screws. I used 6 gauge wire for battery leads which fit clamps but difficult to tighten down. Also no mention of best location to attach the temp. sensor on battery. (tape near the negative battery post) I have not hooked up panels to it yet, only the battery and solar cable leads.

Went through everything... wiring, solar panels batteries Aims inverter, and the Aims Scc30AMPPT charge controller. Found that the charge controller is discharging battery at night. Barely over a year old. I have a Morningstar on another system that has worked flawlessly for 5-6 years. I have lost a battery due to this. I have disconnect all components at night narrowing this problem down. I hope others will have better results than me.

Price and AIMS quality a great combination

I thinks it more of a love hate relationship. Ive had this unit a little over 6 months and for the most part i love it... fanless so it quiet, backlight nice and bright when on and turns off after 5 or 10 secs, mppt, flexable, and easy to understand The bad... the manuel just forget it even comes with one download the pdf much much better. the ports are a little small so wire ferruls are your best buddy i was able to get some 10 awg in but i dont think you can get much bigger. Now for the kicker its gotten weaker with time idk if it the season changeing or my setup but when i got it my batteries where always topped off with this unit then it started dropping off so i thought easy fix added panels now idk anymore about it. I think its starting to drain my batteries instead of chargeing them when its connected to the system

This is a nice, robust looking unit. So far it has worked flawlessly. The instructions are a little short in description, but any guy who is handy enough can figure it out. I did have one issue which thus far doesn't appear to be an issue at all. I noticed when I switched on the load from the menu on the controller, the amber ALARM led lit up constant. This occurred whether a load was actually connected or not. I called the AIMS Tech Service and I have to say, I must have been talking to someone new. He did not seem to be sure why it was doing that and asked me to send in the unit for testing. This was inconvenient as I had just installed it a few days before. Not wanting to risk a fire I followed his directions. Shipping there and back was extremely fast. A three day turn around. They ended up sending me another brand new unit. When I hooked it up again, same issue, amber ALARM led with load on. Manual does not express what this is. However, everything works as expected, load works, batteries charge, etc., etc. Does not appear to be a problem. It seems as though the amber light just signifies that the load feature is switched on. I did email AIMS and explained this to them and never got a reply. That was disappointing. Nevertheless, the unit does appear to be working and doing what it is designed to do. It’s only been about 2 months so I will update if anything negative happens. If no update then it’s still working great. I do believe at this point I am going to be buying another one for my other solar system.

Used on my RV. I restored works great. Nice menu driven options to choose from on the display

Purchased in Feb 2025 finally got everything to hook it up and it not charging my batteries .. need to be replaced but no one contacted me ..

I have had this MPPT solar controller installed now for a year. It has worked flawlessly and continues to do so. The other Aims product I have is a 2000 W heavy duty inverter. Both do the job they are supposed to.
