6 FAQs about [Can 21v solar panels charge the cabinet ]
Can a 12V solar panel charge a 24v battery?
A controller can NOT increase voltage. So, a single 12V panel can never charge a 24V battery. But, two solar panels wired in series could, with an MPPT controller. But, to answer FM's question, MPPT controllers (not PWM controllers) will take the incoming voltage and transform it down to make the voltage the battery wants.
Can a solar inverter charge a battery?
The inverter also supports charging the batteries from the mains power. So if I just plug the inverter into a wall socket, it will charge the batteries. My requirement is that I want the batteries to charge BOTH from the inverter and solar panels (not necessarily at the same time).
Do 12V solar panels put out 24V?
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%.
Do I need a solar charge controller?
In most cases where a 6-watt or larger solar panel is installed, the use of a charger controller is highly recommended. In a nutshell, a solar charge controller acts like an on and off switch, allowing power to pass when the battery needs it and cutting it off when the battery is fully charged.
How many volts does a 12 volt solar panel use?
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%. A 48V battery bank will want to charge at anywhere between 50-59 volts, and for lead-acid that needs equalization, up to 64V.
How much power does a 24 volt solar panel need?
For a 24 volt system the panel at max power rating needs to be 32 to 36 volts. Roughly 16 to 18 volts for every 12 volts of battery. However that rule only applies if you are using a standard PWM or shunt regulator. Using that type of regulator you will loose 30% minimum of the power from the panels.
