Troubleshooting
The primary troubleshooting method is to use the
Communications Gateway for indications of a problem. The
Gateway can be viewed using the touch screen interface on the
device, or accessing it using a web browser. Assuming the issue
is not with communications, browser access has the advantage
that a mobile device such as a phone can be used while
physically on the roof. As detailed later, the inverter has an
indicator light that will also provide insight.
The troubleshooting section is divided up as follows:
