It depends on hour

example: for 4 hour back up


35AH means 35 amps/1 hr


for 4 hrs : 35x4 = 140 amps


Solar watt required - 140 x 12 (Vx I) = 1680 watts


Please let me know this calculation is correct or not

Can you charge a battery with solar panel producing 245 watts?

You can't charge the battery with those 245 watts unless they are being 'pumped into' the battery at a higher voltage than the battery puts out. If you can exceed the voltage of the battery, that 245 watts will definitely charge a battery.


How many watts solar panel do you need to charge 12v battery?

To charge any battery the voltage of the input must be more than the battery's output.


How many watts solar panel need to charge 12volts 7ah battery?

1 watt will do the job.


How much power would it take for a 20 watts solar panel to charge a 12v battery?

about 500watts/meters of irradiance


Can you charge a battery with solar panel producing 80 watts?

You sure can! I charge a marine battery with a 75 watt panel and it goes from a fairly good discharged state to fully charged in about four days.


How many watts solar panel do you need to charge my 12v 100amp battery in 6 hours if you use 5.5amp a hour?

There is too much information there. Charging a 100 amp-hour battery fully would take 18 hours at 5.5 amps, or 6 hours at 16.67 amps. At 5.5 amps the power would be 12x5.5 or 66 watts, and this is the rating of the solar panel required. That would be about 0.4 of a square metre.


How many watts are required to start a 7 HP 12 VDC motor you want to start the motor on solar panel?

For calculation purposes 1 HP is equal to 746 watts. So you have a total of 746 x 7 = 5222 watts. The amperage will be A = W/V = 7222/12 = 435 amps. You can not start the motor directly off of the solar panel. You would need a large 12 VDC parallel connected battery bank to obtain the amperage capacity to start the motor. The solar panels would be connected to the battery bank and used to charge the batteries after the start.


How much solar panel need to charge 12v 180 ah battery?

Well, isn't that a happy little question! To charge a 12V 180Ah battery, you'll need a solar panel with a wattage of around 180-200W. This should provide enough power to charge your battery efficiently. Just remember, it's all about finding the right balance between the size of your solar panel and the energy needs of your battery.

How many watts to charge a 12v battery direct in 6 hours?

To calculate the wattage needed to charge a 12V battery in 6 hours, you need to know the battery's capacity in amp-hours (Ah). Once you have the Ah rating, you can use the formula Watts = Volts x Amps to determine the wattage required for charging. Multiply the battery's voltage (12V) by its capacity in Ah, then divide by the charging time in hours (6 hours). This will give you the minimum wattage needed to charge the battery in 6 hours.


How many watts from a solar panel do you need to power a 6 volt radio?

The power required is(6) times (the amperes of current the radio draws when it operates) watts.
