I really like the digital readout on the unit. Easy to see exactly what's going on. It is compact, and mounted easily. Very easy to hook up. I have nothing wired to the "load" outlet terminals, but have used the USB outlets to charge phones, and they work perfectly. Nice looking controller, and back lit well enough to see in daytime. The only complaint with the display is that you must be looking straight-on to see the LCD properly, and since mine is mounted at about waist-level, you have to stoop to see it unless standing back a bit. Not a big deal, however.
One thing that is a little confusing, and the reason for dropping a star from the rating, is that unless the panel has fairly direct sunlight, it shows no charging current. If the sun goes behind a cloud, it drops to zero. The display shows "daylight" (the sun icon), so it knows it is daytime, but the controller sends no current to the batteries. I'd understand it dropping some, but why can't partial sun give a partial charge level? It was really surprising to watch how quickly it drops off when shade from a tree limb blocks part of the panel, or a cloud covers the sun. When the sun is high in the sky and bright, the controller is sending a nice amount of energy to those batteries, but there is a lot of time during the day that you get nothing, or almost nothing. A bit disappointing, for sure. It may be that the other controller was only actively charging a similar amount to what this one is, but didn't know it since the display was so basic. I still wish it could provide at least a trickle of power at times I feel it definitely should be.
As a whole, this controller seems to be doing its job well, and I like the fact that it gives so much information. I also like that it does not switch off and on like the old one. It does not even get warm when operating, so I know it can handle much more than I'm asking of it.
1. The Output Current is not active until the load is more than 1.0 amps. So when just charging a phone it displays 0.0 amps but when I'm charging a phone, my iPad and switch all my 12 Volts lights on then I see a reading. I guess since its 20A its need a lot more current to have the display going.
2. When the sun comes up the input current shows 0.0A from my solar panels, not until 10 / 11 am I start seeing a reading. Since its only 2 days I've been testing it conditions may change later.
3. The Battery Voltage display readings are accurate.
My conclusion is: Use it where your input and output current is more than 1 or 2 amps, If mA is important to you go for a 10A or 5A model.
