I was thinking of buying (or possibly building) a gas powered 12 volt DC battery charger to charge two to four 6 volt batteries (Trojan T105's or similar) for cloudy days when solar can't keep up.
The Alten 12 volt Honda powered charger at $1300 (aaargh!) puts out 27 amps at 3500 RPM's (half throttle).
Harbor Freight has two cheap generators that claim to generate "2200 running watts" ($500) and the other does "700 running watts" ($130). I don't see anything on the HF site that tells me how many RPM's they are doing during that "running time."
Here are my questions please...
1) Since the Atlen puts out 27 amps at half throttle (3500 RPM's), does that mean it would take about two hours to charge two 50% discharged Trojan T105's to 100%?
2) Does HF's $500 "2200 running watts" generator mean that it will produce 183 amps? If so, can you please tell me how many amps would be used to charge my 6 volt batteries? And same question for HF's $130 "700 running watts" generator that is supposed to put out 58 amps?
3) The reviews are pretty good at the HF site, but have you used one of those HF generators for a long enough period of time to be able to judge its reliability and longevity?
Thanks!
