Solar North: Side Mount – 150 Watt / 140 Ah

Part Number: M75-SOLAR-000N

MUTCD Sign Rings: If your controller is running firmware 401N or >, adjust brightness from 100% to 60%. Failure to do so will result in higher power draw and solar systems may fail.

Is my ring MUTCD?
There is a -M at the end of the model number for MUTCD compliant rings

Summary
