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.
Check that DC strings are wired correctly
Switch off DC isolators and remove MC4’S from inverter
Turn on DC isolators and check for correct voltage and polarity
Turn off DC isolators and plug MC4’S back in
Turn DC isolators back on

Check that you’ve wired the inverter correctly and that all wires are in the correct position.
