If you do not have solar system monitoring installed, the first step is to check for any obvious issues with the solar panels, such as a build-up of dirt, dust, mould, or leaves. Maybe a good wash with a soft broom and water is all that they need. Also, check no nearby trees have grown significantly and are shading the panels.
Check the grid voltage on the inverter display or app for over-voltage issues. Hire a solar professional or electrician to inspect the solar system. Micro-cracks may not cause any noticeable performance issues at first, but over several years, they can sometimes develop into more serious problems and result in system failure.
The first obvious symptom of a solar system malfunction is a blank screen. However, the issue isn’t always that straightforward. A partial display, flickering lines, or even irregular fading are also clear symptoms of a display issue. Now, you might wonder, “why bother if the display is not working when my solar system is still charging?”. A solar system malfunction can lead to inefficient energy conversion or even damage to the system components, so it's important to address the issue.
Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues. Hire a solar professional or electrician to inspect the solar system.
The issue could also be due to insufficient solar power input. The display won’t wake up if the photovoltaic panels are not capturing enough sunlight, or if there’s a problem with the wiring from the panels to the charge controller.
If you're experiencing display issues with a solar sync module, the symptoms and causes are often similar to those of a solar charge controller. You can try resetting the solar sync module by holding the reset button for a few seconds. If the problem remains, you may need professional help.
