With 12V/24V 20A charge controller, it monitors the battery's charging state and protects against overcharging, reverse charging and short circuits. Made with the high quality monocrystalline solar cell, the solar panel guarantees the most efficient solar charging.
The Energian Leisure Battery 200W Solar Charger is the solution for charging all 12v lead-acid leisure battery. It makes a great touring charger for motorhomes and caravans. With 12V/24V 20A charge controller, it monitors the battery's charging state and protects against overcharging, reverse charging and short circuits.
If you have a 24V battery and you're wondering if a 12V solar panel can charge it, the answer is yes! You can charge a 24V battery with a 12V solar panel, but it's not going to be as efficient as using a 24V panel. Since the 12V solar panel won't be able to produce as much power as a 24V solar panel, it will take longer to charge the battery.
A 24V solar panel can charge 120 watts to a 12V battery. If you charge a 24V solar panel to a 12V battery, it will charge at 8.3 amps and draw the voltage down to what the battery can handle. Only 120 watts of the possible 300 watts from a 24V solar panel are charged to a 12V battery because of the low voltage.
To charge a 24-volt battery with a 300-watt solar panel, you’ll need 3.4 hours of direct sunshine. It is dependent on the solar cell quality. At the same time, electricity generation has environmental implications, and you should include the location and weather while calculating everything.
Energian 200W Folding Solar Panel which uses solar energy to generate 18V DC power, Energian 12V/24V 20A Automatic PWM Solar Charge Controller which receives 18V DC power from the solar panel and charges a leisure battery with no overcharging; preserving and extending the life of the battery.
