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.

After waiting for AIMS and others to get this unit back in stock, I picked it up for $120. There is a small LCD display, NO fan which is a good thing for my garage set up. I believe the 458 connector will be useless until there is some software developed IF ever. However, the unit is working fine and delivering power to the batteries. Comes with a 2 year warranty and I purchased a 4 year one since the price was less than the cost of shipping.....

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 ..

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

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

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.

Good unit, but does not have Wi-Fi connectivity for monitoring. Great for basic systems though. Or if you have a separate monitoring system.

Upgraded from the system I had used. Much BETTER now!
