About The charging voltage of photovoltaic panels cannot be reached
The solar charger stops charging if the PV voltage exceeds the maximum rated PV voltage. At the same time, it will display an overvoltage error #33, and will fast blink its absorption and float LED. Charging will not recommence until the PV voltage has dropped 5V below the rated maximum voltage.

If your solar panel is not charging your battery properly the likely culprit are mainly: Wrong Solar Panel Setup, Equipment Problems, Internal Problems of the Battery or Faulty Battery, and Solar Charge Controller Issues. The easiest way to fix them is to replace faulty equipment.
I’ll now walk you through the troubleshooting steps to identify and fix the reasons your solar panel isn’t charging the battery. Using a multimeter to check the voltage of the solar panel under sunlight. If the voltage is low, there could be an issue with the panel or the environment not providing sufficient sunlight.
The solar charger starts charging when the PV voltage is 5V above the battery voltage. Charging continues if the PV voltage remains 1V higher than the battery voltage. To troubleshoot if a low PV voltage is the reason the solar charger is not charging, use the below procedure.
To troubleshoot, check for shading on the panels, faulty wiring connections, or incorrect settings on the charge controller that could be causing the high voltage output. Addressing high solar panel output voltage promptly is essential to prevent potential damage to the system components and guarantee performance.

6 FAQs about [The charging voltage of photovoltaic panels cannot be reached]
Why is my solar battery not charging?
Note that these do not always mean a failed system; they can also indicate a bad battery. The solar battery charging problems and their solutions are discussed below. A solar battery not charging can indicate issues with many things: improper wiring, faulty charging components such as charger controllers, panels, or even the battery itself.
What if the PV voltage exceeds the maximum rated PV voltage?
The PV voltage should never exceed the maximum rated PV voltage of the solar charger. The maximum PV voltage rating is printed on the front or on the side of the housing of the controller, and in the product specification sheets. The solar charger stops charging if the PV voltage exceeds the maximum rated PV voltage.
How much voltage does a solar battery need to be charged?
During bulk charging for solar, the battery’s voltage increases to about 14.5 volts for a nominal 12-volt battery. When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied.
What voltage should a solar charge controller be at?
Once charging has commenced, the PV voltage must remain higher than 80V for charging to continue. WARNING: Depending on the solar charge controller model, the PV voltage can be up to 450Vdc. Voltages above 50V are generally considered to be dangerous. Check your local electrical safety regulations as to the exact regulations.
How to fix a solar charge controller problem?
The easiest way to fix them is to replace faulty equipment. In case of a Solar Charge Controller Problem resetting it and connecting the Solar Panel, Charge Controller, and Battery Properly. The environment also plays a factor but that’s rare. Bad weather conditions can lead to your solar panel not getting the needed sunlight.
What happens if a solar charger is moved from 24V to 12V?
However, if the solar charger is moved from a 24V system to a 12V system, it may not recognise the system change. Consequently, it will continue charging with 24V battery charge voltages, while the connected battery is a 12V battery, leading to overcharging of the 12V battery.
