Another common question I often get when it comes to solar electricity and residential solar power is whether you really need a battery bank and a charge controller. Isn’t connecting the inverter or any appliance directly on to the solar panel simpler?
The answer is yes, of course you could. But all you would be doing is risk breaking your inverter or appliance. With solar panels, the voltage it produces varies widely. On extremely sunny days it could produce a lot of voltage while on cloudy days it could produce very little.
This inconsistency is one of the major disadvantages of using solar power and why it isn’t anywhere near close to replacing traditional forms of energy yet.
Going back, with a battery bank, the load smooths out the voltage and basically insulates the inverter from any damage. Another benefit of a battery bank is that during cloudy or rainy days, when there isn’t enough sunshine to make significant power, the battery bank serves as a back up source of power.
