Input Voltage (PV Generator) too High

When failure occurs, the yellow failure LED is on for five seconds
and then starts the blinking code by staying off for three seconds
and then blinking four times in short intervals. The code is sent
three times.

The Sunny Boy indicates that the input voltage is too high. The
voltage of the PV generator exceeds the respectively admissible
voltage!

Immediately disconnect the PV generator from the Sunny Boy
2800i. Too high voltage may lead to irrepairable damages!

Have your installer examine your plant configuration.

Please have a look at chapter 6 „ Technical Documentation”
(page 31) fo
r the permissible PV input voltage of the Sunny Boy
2800i.
