If you are unable to get the answers you require from the information links below, please don’t hesitate to send us an email direct to one of our product specialists who will be able to assist you with your enquiry.

  1. The first step is to make sure that you do not check your inverter at night. The inverter will be off at night as it has not power to it from the solar panels.
  2. Check that all breakers are in the on position on your DV board.
  3. Shut down the system by doing the following:
    1. Turn off the solar supply main switch and AC isolator.
    2. Turn off the PV array isolator located next to the input terminals of the inverter.
    3. Wait 10 minutes.
  4. Restart the system by doing the following:
    1. Turn on the PV array isolator located next to the input terminals of the inverter.
    2. Turn on the solar supply main switch and AC isolator.
  5. If the inverter is still showing a fault light please take down the fault code if there is one displayed on the inverter.
  6. Email the fault code to us and one of our technicians will contact you to resolve the issue.

The ‘magic’ number for Solar System production is 4.2 kW. This number has been calculated as a yearly average so chances are your system will produce more in summer and less in winter.

If you think your solar system is not working, you may become aware – through a higher than expected electricity bill, through information from a monitoring system or simply by your inverter staying permanently switched off.

If the inverter is switched off permanently then you need to call us and ask for a site visit to ascertain the issue.

In cases where the system is working, but you feel maybe not to its full potential, an assessment of how much energy you generated and consumed over the billing period is the first place to start. This can be found on your electricity bill. Is the bill much higher without you are having changed your consumption pattern? Your solar power system supplier should have provided you with estimates of how much energy you will generate and the first step is to compare the predictions with what your electricity bill, or inverter monitoring system says.

If your inverter monitor shows that your system is generating close to what was predicted, then the issue could be to do with a change in the time or the rate of electricity you are being charged. You should discuss the matter with your electricity retailer. Compare your latest electricity bill with some of the bills from previous quarters or even with the bill from 12 month ago.

If you are generating less than what was predicted, your inverter monitoring system may be able to assist you by describing any faults or errors.

Sometimes a tree not too far from your system has grown a new shoot and now starts to overshadow your solar system. So check what has changed near your solar system. Any new objects which cause overshadowing?

In all cases it is important to remember that solar systems are producing high voltage of electricity. Do never attempt to fix any problem yourself.

  1. Shut down the system by doing the following:
    1. Turn off the solar supply main switch and AC isolator.
    2. Turn off the PV array isolator located next to the input terminals of the inverter.
    3. Wait 10 minutes.

 

  1. Restart the system by doing the following:
    1. Turn on the PV array isolator located next to the input terminals of the inverter.
    2. Turn on the solar supply main switch and AC isolator.
