About The photovoltaic panel voltage is higher than the controller 2
As a general guide, MPPT charge controllers should be used on all higher power systems using two or more solar panels in series, or whenever the panel operating voltage (Vmp) is 8V or higher than the battery voltage - see full explanation below.

Charge controllers are sized depending on your solar array's current and the solar system’s voltage. You typically want to make sure you have a charge controller that is large enough to handle the amount of power and current produced by your panels. Typically, charge controllers come in 12, 24 and 48 volts.
MPPT Range is the voltage range (in this case 125V - 425V) over which your MPPT will operate effectively and be able to extract power from your array. The lower value (100V) indicates the minimum voltage for the MPPT to be able to start working.
PWM controllers are best suited for smaller solar systems with a solar panel voltage closely matching the battery voltage. However, they are less efficient than MPPT controllers, especially when the solar panel voltage is significantly higher than the battery voltage.
As a general reference, MPPT charging controllers can be used on all higher power systems using two or more solar panels or if the panel voltage (Vmp) is 8V or higher than the battery voltage-see full definition below. The MPPT is essentially an effective DC to DC converter to maximize a solar panel’s power output.

6 FAQs about [The photovoltaic panel voltage is higher than the controller 2]
Why do solar panels have a high voltage?
Higher voltages lead to less power loss across a length of wire, which is why long-distance transmission lines have such high voltages. If your battery banks are some distance from your panels, running the system at higher voltage and relying on MPPT solar charge controllers is the best way to cut down transmission loss.
Are PWM controllers suitable for RV solar power systems?
PWM controllers are suitable for small off-grid solar panel systems, of low powers and low voltages – that is, where you have less to use as power and efficiency. These solar controllers are often used in 12V RV solar power systems as a cost-efficient RV solar battery maintainer as well.
What happens if a solar panel exceeds a maximum voltage?
Solar Panel Configuration: The solar panels' output must remain within the controller's maximum input voltage when designing a solar system. If the combined voltage from the panels exceeds this rating, it could damage the controller or cause it to operate inefficiently.
What is the nominal system voltage of a solar charge controller?
The nominal system voltage of the solar charge controller is the same as the rated voltage of the load and the panel array. Nominal PV array current = 2 × 8 (short-circuit current of each PV module is 7 A and are connected in parallel) Nominal PV array current = 16 A
Do solar charge controllers have an upper voltage limit?
All charge controllers have an upper voltage limit. This refers to the maximum amount of voltage the controllers can safely handle. Make sure you know what the upper voltage limit of your controllers is. Otherwise you may end up burning out your solar charge controller or creating other safety risks.
What happens if the output voltage of a solar array is higher?
Therefore, if the output voltage of the solar array (24V, 48V or more) is higher than the battery bank voltage (which is usually 12V), an MPPT controller brings it down to 12V but compensates the ‘drop’ by increasing the current, so that the power remains the same.
