Previously, with 12V systems, that meant adding more panels, larger capacity charge controllers, and huge battery banks, plus all that beefy wiring. Now, many solar consumers with higher energy demands are moving away from 12V and toward 24V and 48V systems for overall cost-space-benefit.
You can use 12 v solar panels to charge a 48V battery but ONLY if you connect the 12v in series to get more than 48V. If more then there is this magic box called MPPT controller that downgrades the output voltage from the solar panels to fit the voltage of the battery? What happens when a mppt controller fails?
With a 12V or 24V battery bank this can be met with a single larger solar panel that may have a Vmpp of 40V... Since that isn't enough to charge a 48V nominal battery bank the "complication" is that you need to connect two of them in series which would double the voltage and then not be an issue charging a 48V bank.
They get the job done for simple projects. But 48V systems are more powerful, like upgrading from a manual screwdriver to an electric drill! 48 volts delivers more power while using less energy. It’s a big upgrade! With 48 volts, you can take on bigger solar projects, just like power tools make big construction jobs more accessible.
Let’s imagine 12-volt solar power systems are like essential tools – hammers and screwdrivers. They get the job done for simple projects. But 48V systems are more powerful, like upgrading from a manual screwdriver to an electric drill! 48 volts delivers more power while using less energy. It’s a big upgrade!
Keep in mind though that 12V solar panels do NOT put out 12V, and 24V panels do NOT put out 24V. A standard 36-cell 12V solar panel has a Vmp of ~18V. A standard 60-cell panel puts out ~30V, and 72-cell 37.5V. A MPPT controller needs some overhead voltage above what the battery needs. Midnight Solar says +30%.
