Do we know of any source of 12-volt panels? Do they think ANY panel is going to be used at 12 volts DC?
This is as bad as the DC/DC boosters that advertise 600-watts but in fine print have a maximum input/output of 10-amperes. Why do you think they do not shout TEN AMPERES in the specifications headline?
Reminds me of my sarcastic remark about MAXIMUM SOLAR OUTPUT on Mercury.
These jokers have to learn to post specifications as obtainable using normal voltages or normal amperages. A billion watt controller is not much good if it has a 10-volt limit and a 300 watt panel is not much good if it is good for 12 volts. use terminology that CONSUMERS understand and work with.
