The first step in choosing a solar charger is to determine your power requirements so that you may get a charger that is neither too small nor too big (and therefore too costly). Getting one that can operate a refrigerator is also unnecessary and is expensive when you need to charge a mobile phone or camera battery. The goal is to choose one that can manage your equipment to satisfy you with real run and charge times.
So, the first step is to make a physical inventory of the equipment and gadgets your new solar charger will charge. We suggest developing a list. On your list, include how many watts or amps your equipment consumes while in operation and how many hours per day you will need to operate those items. As an example, your list should look like this:
Running a Solar Charger requires the following equipment:
Mobile phone 5 watts (400 mah) 5 hours daily are needed.
Laptop with 50 watts or 4000 mah battery. Hours required each day: 3
So, now that we know what our actual power requirements are, we can choose your battery charger. Based on the above example, multiply the number of hours required by the amps to get the total amp hours needed each day for that device.
Mobile Phone 400 mah x 5 hours = 2000 mah required every day to operate your cell phone.
Four thousand mah x 3 hours = 12000 mah required daily to power your laptop.
Total power required daily: 14000 mah (or 14-amp hours) to operate your gadgets.
Features
We now know that we need 14 amps from a solar battery Adelaide daily to suit your requirements. Because you have significant power requirements, your solar charger system will need a backup battery. You may use a backup battery to store power from your solar charger and operate your device directly from the storm. The battery size, which amps will describe, is the specification to search for on our website. To use your equipment for the hours per day you stated, you will need at least a 14-amp battery.
How long will a solar battery Adelaide charger take to charge a 14-amp battery? The solution is straightforward: A 14-amp hour battery can be set in 14 hours using a 1-amp solar charger. Divide the amp hours of the battery by the amperage output of the solar charger. Fourteen amps divided by 1 amp is 14 hours. Use a higher powerful solar charger to minimise charging times.
Bottom Line
Please keep in mind that if you don’t have the amperage specification available, divide the watts of your device by 12 to obtain the amps. For instance, 5 watts divided by 12 is 0.400. (or 400 mah) You now understand that your mobile phone takes 400 mah each hour to function. Most solar chargers produce 400 mah per hour, enough to power a mobile phone without a backup battery. Check for solar chargers that make 400 mah per hour while buying at Bright Earth Solar.
