Volts cannot be converted to amps. If you mean convert 220v to 12 volts output, then you need a 220v to 12 v step down transformer with the VA or watt rating you require.
Yes. Provided that it has above 12 V output. I will. You must have a diode in place though.
12 volt 120 amp heres the sitehttp://www.vicic.com.tw/alternators/gvd12212.htm
A 12 amp current is stronger than a 9 amp current because amperage is a measure of electrical current flow. More amps indicate a higher flow of electricity, which means a 12 amp current can power larger devices or provide more energy than a 9 amp current.
Solar panels are rated in watts output. To find the amperage use this equation, Amps = Watts/Volts. The wattage will be on the nameplate of the solar panel.
20 amp on a 12 volt system
Yes, you can.
To charge a 200 amp-hour battery with a 1000-watt solar panel, you first need to convert the amp-hours to watt-hours. A 200 amp-hour battery at 12 volts has 2400 watt-hours (200 Ah × 12 V). If the solar panel operates at peak efficiency, it can produce about 1000 watts, which means it would take approximately 2.4 hours of peak sunlight to fully charge the battery (2400 watt-hours ÷ 1000 watts). However, considering factors like inefficiencies and varying sunlight, it may actually take longer in practice.
It depends on the output current. In general, the switching power supply is most efficient.
AWG 12/2 requires the use of a 20 amp single pole breaker.
12 amp more than likely. Hmmm... I'd start with a 10 amp but never higher than the rating...
12 ga, 20 amp. 14 ga, 15 amp. 16 ga, 10 amp.
Depending on size and voltage output, higher than battery maximum output at an ampere rate that wont "cook" the battery. For example: a car battery placed on a 40 amp charge rate for 12 hours in most cases will "cook" the battery. But placing it on a 2 amp charge rate will fully charge it over the same time interval.
