The "12V" means it has 12 volts, which is the electric power. To explain it simply, this kind of battery can give out 12 volts and can do so at a power of 20 amperes for one hour.Now, let's see what you can do with a 12V 20Ah battery in your solar off-grid system.
1) Smartphones and tablets
Charging the phones and tablets is easy with this battery. Usually, a phone has a battery power of about 10-15 Wh. This tells you that you can power a smartphone around 15-20 times before it needs to be plugged in again.
2) Laptops
Laptops, depending on their kind, usually have battery power ranging from 30 to 60 Watts. You can expect a laptop to be charged 4-8 times with a 12v 20Ah Battery.
3) LED lights
LED lights are very good at not using much energy. This makes them really suitable for systems that don't have an electricity grid. If we have a light that uses 5W, it could work for nearly 48 hours on a battery fully charged with 12V and 20Ah from SM Solar.
4) Portable fans
A compact handheld fan that uses approximately 5-10 watts of energy can keep working for a long time with this battery. You can expect it to be in use for anywhere between 24 to 48 hours without stopping.
5) Small refrigerators
A small, energy-saving fridge or cooler can also work on Solar Off Grid Systems, but it will last a shorter time. These gadgets usually take about 30 to 60 watts to run, so they can give you 4 to 8 hours of use.
