Afore inverters on installation procedure check list

Installations of Afore Inverters

99% of the time we get a call to say that an inverter is faulty. We find out that it has not been fitted correctly. Check inside the box all Afore inverters come with a wiring diagram showing weather it should be wired as one or two strings. Eg: 3600tl-10 0r 20 is wired as 2 strings.

If you have a problem or think that you may have problem with the inverter then please go through the procedure check list first.
