Wanderer Li 30A PWM Solar Charge Controller 12V for Solar Panels

Works good and is nice when you add the blue tooth module to see how much solar your getting

This works really good I like the three different settings for sealed batteries, flooded batteries, or lithium. I started to send it back because I didn't really need it but then I canceled my return and decided to keep it

Easy install, worked great. would get 5 stars if it had bluetooth installed, but I use my battery's to monitor.

Great control head for our solar shed

Great solar controller! Simple to use. Would definitely recommend!

If you bought one of the cheap $10 blue solar panel controllers, and you had a whole lot of trouble getting hands on a gauge of wire small enough to fit in their tiny connectors, and stripped wires 3 times at lease, just to have it all fall out, then THIS IS WHAT YOU NEED. I screwed each wire in, within 10 minutes, no frustrating do-overs or readjustments, or experimenting with duct tapes! I set the battery type manually and was done, as satisfied as can be. Not having a USB or light connections like the cheap blue ones, (I think the brand is Flying Lion btw)... is a bummer, but at this point, I am happy my setup works again! And I can even get a larger gauge wire in there if i wanted! Even the screw was bigger, and required a bigger phillips screw driver (cross size). It clamps down on the cords soooo well!

This was the only change I made on my solar system in my rv. I had noticed that the batteries were going dead faster than they use to. I did some testing, nothing wrong with the batteries. The solar charger I had was an older one, but seemed to be working. After some testing I was only getting 1 to 2 amps of charging in full sunlight. I checked all the cables, cleaned the panels, same problem. So, I figured it had to be the controller. I ordered this one and installed it using all the same hookups as the old one. I noticed a big change right off the bat. The old controller said the batteries were fully charged. This one said they were at about 70%. I still have flooded batteries in my system, so 70% is really not even close to what they should be at. On the first camping trip this year, it was colder than normal. One night got down to 31. I ran the furnace all night. Got up in the morning to still having power. With the old controller, the batteries would have been dead in the middle of the night. I also got the bluetooth adapter for this.....love it, very easy to setup and use...

No output right out of the box. Sent it back

No complaints at all so far. Plugged a 160W Kings Folding panel into it, and in late afternoon, Winter sun on the east coast of Australia, angled towards the sun the best I could, I was pulling 7.85A out of this controller which is more than enough to keep my fridge running indefinitely off my lithium battery. Don't let people tell you that an MPPT is superior, because for small panels, there's very little difference in my experience. Excellent controller that I bought as a backup in case my CTEK blows an internal fuse (again) and is totally useless. Build quality is good, hard plastic with an aluminium base plate. The grub screws hold 8AWG cable very well and it won't pull out on their own easily. The LED indicators are very bright and easy to see in sunlight too.

Works very well. Excellent quality. I have setup to run LED lights system in a Cabin. Keeps AGM battery charged all year round, through hot summer and cold winter. It’s a simple rugged design. Flashing light will tell you when battery is charged.

Works perfectly very fast delivery arrived 2 days early great bit of kit

I brought this as an upgrade from one of the unbranded charger controllers to give me some room to upgrade and as with all the other Renogy kit I've installed it hasn't disappointed. Holds a better charge voltage for longer delivering more amps and handles cloudy cover better than the cheap unit. Worth the money if you're not splashing out on an MPPT.

I bought this charge controller to replace the very cheap and nasty default controller that came with my solar panels. This one works very well. Simple to use, just has solar in and battery out. No load connections, and for my set-up that is perfect as load is directly off the battery. The controller has start, bulk and float charge modes. There is a maintenance mode but that hasn't been activated yet. I also bought the BT01 adapter so I can use the app to monitor it.
