This was dead on arrival. Hooked it to my system and got nothing. Disconnected it and temporarily hooked up a controller that is too large for my project and everything worked fine. I will be returning this to Amazon.

Was for a 25 watts portable solar power project for an amateur radio repeater. It performed flawlessly for power management, but it injected a tiny bit of electrical noise into the radio audio. Tolerable, though. Would buy again.

LNEX Solar Charge Controller 30A was easy to setup. One button programs the battery type. It has the LIFEP04 option. The second button displays the charging information, battery voltage, solar amps, solar wattage and Ah. It has a compact design that is also waterproof.

Bought for a small project to charge a 6.5ah 12v LiFePO4. Did so very well with a 20 watt panel without issues. Seems to be decent quality. Might get another eventually

Super happy with this charge controller. Love that this is 'multi-chemistry' as well.I use this with my amateur radio and I haven't noticed any noise or hash on my scope. Seems to completely power down when the solar panel is disconnected, so I plan on mounting the controller to the battery housing.It worked to top off my 12ah LifePO4 battery with only a 30watt solar panel. For the price, this is a great deal. Sure MPPT would be more efficient, but you're looking at 5x the cost for a Genasun. For a hobby project, I can't justify the additional expense.Will install proper connections and take it camping with us next month!73

I've used three different ones and they don't last long. But I think this is best one yet. I use it at barn to power 12 volt gate and it gets a little moisture on it when foggy or rains a lot. This one will work on all batteries. I set it up with two outlets and maintain gate batteries and tractor , lawnmowers or work truck thru the winter.

I needed a weatherproof charge controller for my RV and order this one. It worked great until I connected it to a second set of solar panels that have a 60V output and burned it out. After I did this I reread the owners manual (who does that first) and, sure enough, it tells you not to connect to a voltage greater than specified.As long as you are using a low voltage panel to charge 12 or 24 batteries this works fine.

Been running this controller in my shed for months now, have a 100 watt panel hooked up to it to keep my batteries full on my equipment and a house battery to run small tools.
