6 FAQs about [The high voltage distribution cabinet connected to the solar panel keeps flashing]

Why is my MPPT solar panel generating high voltage?

This issue may stem from a malfunction in the MPPT solar charge controller or the solar panels themselves. 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.

How do I troubleshoot a high voltage solar panel?

Why is my solar inverter voltage so high?

An abnormally high battery voltage reading can be a sign of a malfunctioning charge controller. The controller might be feeding too much power to the battery, causing the high voltage. Resetting the charge controller, or in severe situations, replacing it, can resolve this solar inverter issue.

What happens if solar panels run at high voltages?

Strings of solar panels operate at high voltages, up to 600V or higher. Operating at these elevated voltages over many years can, in some cases, allow a current leak to develop through the cells to the aluminium frames of the solar panels and into the earth, resulting in a significant performance loss.

Why are my solar panels overcharging?

When the solar panels generate high voltage, it can lead to overcharging, which is detrimental to the battery lifespan. This issue may stem from a malfunction in the MPPT solar charge controller or the solar panels themselves.
