Did some research and wanted to go with a 24v solar pv setup on the roof (520 watts total), but still have a 12v battery bank. You'll need an MPPT controller for this, and the Tracer by SainSonic 30amp controller works great. I have it hooked up to 2x175ah AGM batteries, and it keeps them charged and ready. It's interesting too how it takes a 24 volt input from the solar panels (actually closer to 34 volts in the direct sun), and down converts to a 14.5 volt charge and increases the amperage from about 10 amps from the panels to over 20 amps feeding the batteries. Makes for a quick recharge for my battery bank. I recommend getting the plug-in digital meter so you'll have some idea what's going on with your system.

We purchased this item from Amazon in 12/12. It was set up and running by the end of the year. All associated components (solar panels, batteries, wiring, etc.) were new. At first it worked as expected. After a couple months it started to take a day off" sometimes. It then would work again. We contacted customer support and they agreed to work with us. The next problem that then started was that the battery charge indicator light would be blinking green (full batteries), but no power was available. A battery voltage check showed about 12v instead of the 14.4v cutoff for charging (the point at which the light should blink). Any attempt at introducing a load, no matter how small would blow out the fuse in the battery circuit, but never the fuse in the load circuit (10A). After many attempts on their part to try to make it my fault, they agreed that it was a faulty controller, but that since more than 3 months had passed by then, return shipping was my problem. They promise to refund my purchase amount within 5 days of receipt of the controller. If there is any further problem with the return, you will read about it here. It worked ok when it worked, but customer service could not answer ANY questions put to them (such as determining the rating for the fuse in the BATTERY circuit). It has a 30A solar input limit so I used a 30A fuse (the instructions call for a fuse, but don't give a clue as to it's amp rating). They couldn't say if that was right, wrong, or even seemed to understand that I was following THEIR own directions. 3-4 stars for operation (when it works), 3 stars for prompt (but uninformed)customer service, and 1 star for me paying to return it. **** Our money was refunded within 5 business days as promised. Once again, the customer service was prompt and courteous, but not helpful other than just having us send it back.

I have just fired up this Controller. I followed the connection sequence and the start-up procedure, and everything turned out perfect, I am currently only feeding in 200 watts of panel power , but I will be adding another 150 watts soon. I love the fact that it can handle up to 150 volts of panel input, so hooking the panels in series allows for much smaller losses through the wiring and more current into the batteries for quicker battery recovery time. Nice construction and clean step through start-up make this unit A+ for me.

This MPPT controller is awesome. I got 3 100 watt Renology matched panels (the best) and hooked them up in series to this controller. The batteries were getting charged way past sunset actually until it got dark. The controller puts way more in the batteries then a PWM (almost 15 volts). I like the feature of extending battery life with its battery optimization. I noticed the batteries are getting fully charged with this controller. I have the prowatt SW2000 inverter so I can run the refrigerator or the air conditioner. The solar panels and the controller keep up with the small air conditioner on a sunny day. The only downside is that my wind charger sensed to much voltage and kicked on the brake. I moved the wind charger to another battery bank. You may not be able to share the battery bank with a wind charger. The manual is not that great just adequate. It is easy to set up; connect the solar panels then connect the batteries and change battery type done.
