MPPT solar charger manual
• Dirty solar panels.
• Incorrect orientation or inclination of the solar panels.
• Broken or faulty solar panels.
• Issues with wiring, fuses, circuit breakers, or there is a cable voltage drop.
• Incorrect usage or malfunctioning splitters or combiners.
• Part of the PV array is not functioning correctly.
• The PV array is too small for the desired output.
• Mistakes in solar array configuration.
• The batteries may be too small or aging, resulting in a reduced capacity.

8.8.2. Maximum output power relates to battery voltage
The solar charger's output current is limited to its rated current, resulting in varying output power depending on the battery's
voltage.
For instance:
In a 75/15 solar charger with a 15A output current rating, the power going into the battery will differ for a 12V battery and a 24V
battery.
• For a 12V battery, this is 15A x 12V = 180W.
• For a 24V battery, this is 15A x 24V = 360W.
Thus, even though a 360W panel is connected to the solar charger, the output power into a 12V battery will be less than when
connected to a 24V battery.
