11.4 CONTROLLER FLASHING
Possible Cause:
This behavior is usually the controller dealing with a very high C or voltage rate (Above 15.5 volts). Even though the controller can
handle up to 30A, if the battery capacity is too small for the panel input current. The voltage shoots up too high, too quickly, tripping
the high voltage flashing. Solution increase battery capacity.
Can also be caused by an unregulated converter or alternator, in the system that is putting current to the batteries at the same time.
Remedy:
The solution here is to unplug shore power and reset the controller, which can be done in two ways:
1. Soft Reset - This is done by holding down all 4 buttons on the front of the controller for 15 seconds. If this does not work or you
do not have a 4-button controller, a hard reset is required.
Hard Reset - Remove all 4 wires from the back of the controller for 15-20 minutes, then reconnect the wires. Determine if this
1.
clears the error state.
If the problem was "fixed," then it was because the user started using loads which divert some of the input current because the panels
became dusty or shaded, or because there was less sunlight.
