Symptoms:
Maximizer is communicating but not generating power.
Troubleshooting Steps:
Reset the maximizer in Gridshare (see article 4.7 Reset Maximizer in Gridshare).
If the Maximizer/s are in the middle of the string (closest to ground reference) try resetting the maximizers on the ends of the string in Gridshare. Reset them 3 times in a row, 10 seconds apart, to make sure the reset is long enough to fix the problem.
