Bought MultiPlus 12/3000/120 10 months ago for my boat. Has been working great! Really like it. About a week, we had a shore power outage and the inverter would not turn on. Very strange. Always worked perfectly. Got the manual and did the reset of turning off the shore power and the unit power button off for 4 seconds and then back on again. Nothing. Is there a way to reset? I've seen similar questions to this one, but no answers... Any help appreciated Anthony
