choice of energy battery is crucial
When you need to run small equipment, a 12v 38Ah energy battery is a very good choice. Because it is light, affordable and powerful. Compared with large batteries, whether it is lead-acid batteries, gel batteries or other types of batteries, it only needs a small solar panel to charge and store electrical energy.
WHC 38-12 12v 38Ah 40Ah solar panel battery storage requirements
number of solar panels you need depends on the power consumed by the battery. Therefore, the performance of our solar panels is also very important.
Let us calculate the wattage of the 12v 38ah and 12v 40ah batteries again, using 38ah x 12V = 456W, 38ah x 12V = 480, so at least 456 watts or 480 solar panels are required to fully charge the battery. Due to some fluctuations in the production of solar panels, in order to obtain a safer charging guarantee, a 550-watt solar panel should be used to charge our batteries and store energy.
How long does the 38Ah 40Ah 12v lead-acid battery last?
A 38ah or 40ah 12v lead-acid battery, other batteries with different amperes and volts are the same, depending on their own load and consumption amperage. Our WHC solar 12V 38Ah battery can achieve 100% discharge. During the loading process, small household appliances can provide loading according to different powers. The higher the ampere current, the faster the discharge. This is not a defect of batteries, but the way they work. Regardless of the type or size of the battery, as you use more amps, it will consume faster and faster. Just like charging, you cannot predict the battery life with 100% accuracy. Therefore, our small Abe battery products are most suitable for short-term use, camping, weekend trips, emergency lighting, etc.
