SamlexSCC-30AB Charge Controller

I put one of these onto my travel trailer almost two years ago and it works flawlessly. I have 3 - 250w / 24 volt panels through this into 4 Crown 6-volt deep cycle batteries. In the full summer sun tops out around 28amps so I'm pushing this controller near its max of 30amps. It's ability to handle the heat in here in the desert is a big plus as the travel trailer will see temperatures in excess of 118ºf on the inside sitting in the driveway. It's great that it is a PWM controller as those are best for mobile as opposed to stationary applications. As I understand it MPPT controllers do not like to be moved around as it shortens their life. Just be sure that air can flow behind it and don't mount it next to a heat source. I just bought this as a back up because in case of EMP or CME to go into a faraday cage which appears to be more likely everyday.

Works great but does have some interference with the VHF. Have to hit one of the buttons and it stops making noise.. Strange and wish it didnt do that. Anyone know how to isolate that?

very glad i puchased this and would reccomend it to any body that is passible looking at getting one. easy to use, hook up and operate

Good panel but several issues with my application. First, when installing this in a wall DO NOT trust the mounting template that's included in the box. I used the template and followed the cut-out pattern precisely only to realize when installing the panel that the cut-out was too big! I placed the cut-out up to the back of the controller and confirmed that the template was about 10% larger than the panel itself and none of the screw holes even lined up. I had to patch the cut-out to make it smaller and found myself fuming with frustration. So make sure you match the template up to the controller to make sure Samlex didn't screw up. Second, the suggested battery settings for my batteries (vented, flooded, lead acid) will not work with the inverter in my camper. My inverter shuts down when the input voltage is over 14 volts and the Samlex controller was putting out 14.6 volts during it's absorption stage and was tripping my inverter. To correct the issue I had to use the setting for sealed non-vented batteries which puts out 14.1 volts during absorption allowing my inverter to continue operating. Unfortunately this setting eliminates the equalization feature and isn't the recommended setting. Third, the decal they place on the front of the display is already curing up at the edges and where the screw holes are so I had to use some super glue to keep the edges and corners down. Fourth, the controller generates interference on the 12v power system that is picked up by the radio and TV. I was getting a hum out of the speakers when the controller was charging. I had to install a noise filter/choke (additional purchase) on the camper stereo and the television RCA outputs to eliminate the humming noise.Overall the controller seems to work okay and looks nice mounted flush on the wall but I am disappointed with the attention to details and the functionality of the controller for my application. I was expecting more when I made this purchase

Nice quality construction and seems to work fine. Perhaps not the complete functionality of a Bogart Engineering Trimetric solar controller and battery monitor, but the price is a lot less and the dip switches allowed me to get very close to customizing it to the specs recommended for my Trojan deep cycle batteries. Only the equalization voltage was a little lower than recommended. The reviewers who complained about the decal on the front coming loose did not know that it is not a decal ...there is a clear protective plastic sheet over the face that you are supposed to remove after installation!

If your starting, or upgrading , consider this charge controller , you can't go wrong.

It's Great! Great price and just what I wanted.

Installed this in my rv along.with a 245 watt panel. Output is great. Doesn't boil the batteries out. I would recommend to anyone who asks.
