Adding a 48v inverter to an existing 12v system
You''ve got a mish-mash of panels up there and when you start mixing & matching panels you have a lowest common denominator issue where 1 panel can really nerf the rest of them. Example with napkin math with 3 panels: You have 1 panel rated for 100w with a Voc of 22v, a Vmp of 20v and an Isc of 5a. 20v × 5a = 100w.
How Many Watts Can a 60 Amp Charge Controller Handle?
A 60 amp charge controller has a maximum capacity of 1440 watts for a 24V solar panel system and 2880 watts for a 48V system. When an MPPT senses there is a voltage difference in the system, it reduces the higher voltage to match the lower voltage. The solar panels, battery and charge controller end up with the same voltage rating.
How Many Solar Panels Needed to Charge a 48V 200Ah Battery?

How to choose a Solar Charge Controller :: 12V solar panels
NB: In some rare cases, a solar panel can be connected directly to a battery, without a controller. This can be achieved if the nominal voltage of the panel is lower than 17-18V, and if the solar panel is a lot smaller than the charging battery e.g.. a 10W panel charging a 100Ah battery. There are many different types of controllers on the market.

The solaredge unit with 2x160W panels would basically run in passthrough, and the units with 2x100W panels would drop the output voltage to boost the current to match the output current of the 2x160W panels. While it worked, I was still hoping to get an optimizer per panel since shading varies all the time on the roof of a van.

What Size Charge Controller For a 300 Watt Solar Panel?
In short, a PWM controller will match the solar panel voltage to the battery, dropping from 18V to 13V. If you use an MPPT charge controller, the system will draw the full 18V from the panel. So that means 5.2A x 18V = 90 watts. That is a 25% increase over a PWM controller, but this will only happen if the temperature remains around 77F.

6 FAQs about [How to match 48v20A with solar panels]
Can a 12V solar panel charge a 48v battery?
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?
How to buy a 48v battery?
If you want to buy a 48V battery, you have to use the right solar panel sizes and voltage to get the best charging time. Three 350 watt solar panels connected in a series can charge a 48V 100ah battery in a day. For cold areas, the panel VOC should be between 67 to 72 volts, and for hot conditions it should be from 80 to 82 volts.
How many solar panels can a 20A MPPT charge controller handle?
A 20A MPPT charge controller can handle a 48V system up to 1000 watts. Most 48V charge controllers have a VOC capacity of 150V, good enough for 3 solar panels. There are also 250V MPPT charge controllers that allow you to connect up to 5 solar panels. To find out what charge controller size you need, use this formula: Watts / volts = amps
How to connect solar panels?
The other system components, such as a charge controller, battery, and inverter. There are two main types of connecting solar panels – in series or in parallel. You connect solar panels in series when you want to get a higher voltage. If you, however, need to get higher current, you should connect your panels in parallel.
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 to choose a solar panel & battery?
