Sunforce 44444 12-Volt 400-Watt Wind Generator This instant

I am writing to help people understand about voltage(V), current(I) and power(W). First off, the max voltage and the current that the wind generator is rated at is probably in the form of Voc and Isc which stands for voltage(V)open circuit and current(I)short circuit. Voc is measured in parallel but Isc or current can ONLY be measured in series or in-line with the the source, NEVER in parallel. To get an accurate Isc reading you must "short" or close the circuit with the measuring device as the load of the Generator. Unless you have an AMP clamp, current transformer(CT) or some other way to measure higher current, you can't get an accurate measurement. Most multimeters can measure current BUT most CAN'T measure more than say 10 Amps. Anything more then that will usually result in a burnt fuse or worst, a burnt meter. This also describes how they got their figures(Watts and Amps). Under Voc and Isc the voltage can be about 21V and the current could be about 20-25 amps. Only under a load will the voltage go down to aprox. 13-14V and the amperage will also drop accordingly. The way they got their voltage, amperage, and wattage figures are in of course perfect wind conditions and typically will be much less on average. Therefore the figures are correct but they will never be seen unless you measure them in the perfect wind conditions under zero load as stated above. As for the Amperage, unless you have all the necessary charging equipment you dont want to see more then say 6-10 amps going to a wet cell battery anyway because you can overcharge or damage your battery or batteries, maybe even explode. I hope this makes scence and helps some people. I dont own this Generator but I would buy it if i had more wind where i live.Get more detail about Sunforce 44444 12-Volt 400-Watt Wind Generator.
