GudCraft CD7.0 12-Volt Wind And Solar Power Hybrid Charge Controller

When I ordered this hybrid controller I ordered it to furnish "automatic" charging for my homemade solar and wind power setup.

Well, when I opened the packaging, and took out the controller, it was much smaller than I had expected, and when I read the instructions for it, they made NO SENSE whatsoever!

I have had to do some guesswork to figure out what some of the symbols mean, and how you're supposed to connect your wiring to keep from destroying this controller.

This was bought as a 12 volt controller, but the so-called instructions said it was for 12 or 24 volt. However, where the battery output connectors are located, the instructions said one side was for 12 volt, and the other side was for 24 volt, and there are only two connectors! Come on! It is very obvious to anyone who knows about d.c. power that one connector HAS to be negative, and the other positive!

Whoever typed the instructions for this controller had absolutely NO idea what they were talking about!

About the only useful part of the instructions was where it actually told how many watts the controller was capable of handling from wind input and solar input. This information was NOT on this site for the device!

The maximum throughput this controller can handle for wind is 600 watts. 300 watts for solar power. Since I had ordered a 750 watt PM alternator for wind power, I had to order a rectifier to use for my wind generator. This controller cannot handle more than 600 watts for windthat is its' stated maximum.

If you intend to use this controller for "help" with your electricity production, it might work. However, if you need to use it "off the grid", I doubt this controller will meet your expectations. So just be careful is my suggestion.

They need to include a lot more information on this page about this controller than they have here.

I received this item without a manual. Repeated requests to Gudcraft to supply a digital manual met with no success. The product is therefore not documented which makes it useless. I own two other Gudcraft products their 400 watt turbine and the charge controller that comes with it. The documentation for those products is just plain horrible, so I shouldn't have been surprised that this item was going to be a disappointment. Not buying this brand again -finally learned my lesson.
