1 WARNING - 5 STARS
on November 18, 2011
I am extremely pleased with the performance of this solar panel. We have one installed in a small cabin style 12-volt system intended only to charge personal electronics at a remote location. Just add a deep cycle battery and a DC to AC 120 power inverter, such as the Cobra CPI 480 400-Watt 12-Volt DC to 120-Volt AC Power Inverter with 5-Volt USB Output. It is great!
One WARNING for those new to such systems like we were. The charge controller that comes with this kit is just fine, but it is only for *MAINTAINING* a 12 volt battery. If that is your purpose, buy *this* kit.
But, if you want to add an inverter so that you can have AC, USB (and we even added a 12 volt car socket which is the most efficient), then buy the same panel *without* the charge controller and wiring kit. What you need is a charge controller like the Kintrex SPC0601 7 Amp 100 Watt 12 Volt Solar Power Charge Controller, and various connectors of course. The Sunforce controller only has connections for the solar panel and the battery. The Kintrex adds a load connector for power output which isolates the charge controller and gives you usable power output to your inverter. If you try to parallel the battery connection to your devices like I naively did, you risk overcharging your battery. (I vented a little hydrogen and oxygen, but did not do it long enough to ruin my battery.)
I will definitely be buying more of these panels for other projects. Once you understand the fairly simple wiring you can easily create a great low power system for a cabin. (Next, we will build a 60 or 90 watt system...)
