60A MPPT Solar Charge Controller, 12V/24V Auto Tracking Solar Panel Regulator with LCD Display Dual USB Port Multiple Load Control Modes Timer Setting, Fit for Gel Sealed Flooded and Li Battery(Green)

For the cost these seem to do well. I've bought 4 so far

This is no high end MTTP. It comes with no bells and whistles. However, I like it because it is so simple. I hooked it up to a battery and it does the job. This is perfect for a small application like supplying lights to a small shed that is leak proof. My use has been to test batteries with it. I put in two leads, hook up to + and - and I get a nice reading. My plan is to mount it on a piece of plywood, hook leads up to a battery, then hook up lights. This gives a nice voltage reading. For the money this is more than worth it. Sure beats a permanent connection of my volt meter. Hooking up a solar panel or two is very very simple because it has a single standard 5.?? lead input. I ordered a lead with + and - connections to my solar panel.I have no idea how top-of-the-line the parts are, but for the price I don't need to know.

I bought this as a replacement for a charge controller that broke because I moved the solar cell and the wire became loose. I tried to tighten the screw holding it in the. Controller but it stripped. The screw slots are made of very thin metal and strip easily. The controller works great, it's just the connection slots that are of poor quality.

This little thing will damage your equipment. This charge controller blew up 2 radios because power output was from 20V to 42V. It was purchased for testing the low end quality of these types of products and while I was hopeful these were so simple that anyone could make a decent product. The truth is no not any company or device will work. We did follow directions and test the output voltage before walking away from the device but almost immediately voltage spike were being recorded and at 32V we lost 2 radios and when we saw a 42V spike we stopped the experiment before we damaged something expensive. Don't waste your time or money. Even if you don't loose equipment from the first spikes, these spikes will damage batteries, shut down a BMS on a Li batt killing you charge cycles or turning off everything down stream. Unclean power is harmful to anything and everything connected to it. If you buy a good DC to DC converter to put between this and your equipment then this will work, but its still going to break something eventually (the converter) and if you're going to add stuff to it then why not just buy a better one to start with?

Nothing fancy. Simple, nice features and very affordable. Works great for me.

I like the versatility of battery types and flexibility of solar input offered by this controller, it's nice that it has USB outputs as well. The terminal strip has a definite "project" air about it, but I'm OK with that. The additional option of connecting panels via 5.5mm plug, and some load via 5.5mm plug as well, is nice, though those are not very high power rated plugs, so should be used only for low load items.I'm a bit disappointed with the throughput efficiency; with two "100W" (in quotes because they're not really, they tested at 75W each) panels connected, the peak power throughput I could get with this controller was 90W (13.6v at 6.6a). That's with two separately-tested 75W-each panels, parallelled for 150W of total input, on a scorching cloudless 100+ degree day, at 5k feet elevation, without a cloud to be seen, between noon and 1pm, panels on a flat vehicle roof pointed right at the sun. Net, roughly 60% efficient.So this does get a positive review in that it works, it will charge a battery, and will support a load, but if you're planning on extended use, sharpen up that pencil, crank some math, and assume this charge controller will siphon off roughly 40% of your available solar input somewhere, not to be usable by you.

Like the color of the unit. It looks to have all the bells and whistles on it. Will work good for my small stand-alone system. Looks well-made and don't see any issues with it.
