Solar Charger & Truck Power Question
I've recently installed a Go Power! GP-PWM-30 30 Amp Solar Regulator because the previous owner had solar installed but no charge controller (he just had a simple diode or voltage regulator that conne...

If operated at zero volts (output short circuited - *zero volts*!) it will STILL produce near its rated current. It acts like a current source.
On the other hand if an alternator output is operated at is set point of 14.7 volts, it will produce zero current.
Those both are utterly ridiculous statements, as it applies to battery charging....which is what this topic is all about.
In the first example, the panel itself might still produce it's maximum current but it won't be useful to any external load and especially to a battery which has a voltage that must be overcome before any charging current will flow. But you would know that if you got past 8th grade science. Note: And each cell in the array still produces a voltage too or else there would be no current.
And if the alternator in question is connected to an external load, it absolutely will cause current to flow in the load.....or in a battery with a voltage of less than about 14.5.
The "information" that you are providing here does nothing to help the layman understand battery charging or indeed the fundamentals of electricity either.
You are doing the community as a whole a huge DIS-SERVICE by continuing this pointless ranting.
