The Solar Charge Controller Max Input Voltage refers to the highest value of the solar panel output voltage that the controller can possibly withstand.
Different types and sizes of solar controllers have different maximum input voltages.
The maximum input voltage varies depending on the controller, from 50V, 100V, 150V to 600V.
Max PV Input Voltage
The maximum PV input voltage refers to the highest value of solar panel voltage that the controller can accept without damage.
This is where the concept of the open circuit voltage (VOC) comes into play. The open-circuit voltage of a single panel is the same.
The Max PV input voltage is the maximum open circuit voltage formed by several PV panels connected in series or in parallel.
A PV module’s open circuit voltage is approximately 36V.
Many modules can be connected in series, and the series voltage can reach 600V when applied in a circuit.
What is the Maximum Input Voltage of MPPT Charge Controller?
The maximum input voltage of MPPT charge controller is typically 150V. Some large models may have a max input volts at 200V, even 600V.
PWM Solar Charge Controller Max Input Voltage?
PWM charge controller maximum input voltage is typically 50-100V. For solar controllers under 60 amps, the typical maximum input voltage is 50V, with some 60A and 80A PWM 48V controllers having a maximum system input voltage of 100V.
What is maximum solar input voltage?
The maximum solar input voltage refers to the highest value of solar panel voltage that an inverter-equipped charge controller is capable of accepting without damage.
The open circuit voltage of a single panel is typically around 36V. Most panels are rated at 48V DC.
This means that if your controller supports this type of connection, you can connect up to six similarly sized panels in series and achieve a system voltage out of 600V or higher.
What happens if the solar charge controller’s maximum input voltage is exceeded?
If A solar charge controller received A higher voltage than its rating, it will probably trip or damage the controller. If this happens while your system is in use, you may experience:
Incorrect power output
Loss of energy
How many volts can A solar charge controller handle?
A solar charge controller can handle a maximum of 150 volts. Some larger, model solar charge controllers may be rated for up to 200 volts.
For some parallel installed controllers, it may handle 600V PV input.
