6 FAQs about [The photovoltaic panel power exceeds the controller]

How do I know if my solar charge controller is over-paneling?

Check the datasheet of your solar charge controller for the maximum input current. Victron labels this as max pv short circuit current. When over-paneling, the solar charge controller will limit the current it delivers to its maximum rated capacity.

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.

What are the disadvantages of overpaneling a solar system?

Increased Costs: Overpaneling requires more solar panels, which increases the initial investment cost of the solar system. This can be offset by saving money on another charge controller. Space Requirements: More solar panels require more installation space. This can be a limiting factor if space is at a premium.

Does overpaneling harm the controller?

This is why overpaneling doesn’t typically harm the controller. However, there are a few things to keep in mind when considering overpaneling: Efficiency: Overpaneling can be less efficient because the extra power produced by the solar panels when the sun is at its peak is not used.

Does an MPPT controller provide power to a battery based inverter?

But we agree that a MPPT controller can (and often does) provide energy to a load (instead of to a battery). Will an MPPT charge controller supply power to the battery based inverter when the batteries are fully charge and there is plenty sun.

What are the benefits of overpaneling solar panels?

Maximized Energy Capture: Overpaneling allows you to capture more solar energy during less-than-ideal conditions, such as cloudy or overcast days. This can be particularly beneficial in regions with less consistent sunlight. Better Winter Performance: Solar panels produce less power in the winter due to shorter days and lower sun angles.
