Just installed a Phoenix 12/2000 replacing an old modified sine wave 1600watt, all powered by 3x110Ah yuasa sla batteries. My partners 1200w Babyliss hairdryer creates an overload shutdown. Any ideas why please? Thanks.
I have found with some appliances, like hairdryers, the wattage is not the maximum wattage of the appliance, but the average. So, the thermostat turns on for say 1/10 sec, off for 1/10 sec you have a 50% duty cycle, however, the appliances draws 2400W maximum but the average is effectively 1200W. The maximum demand is enough to trip the inverter out on overload. I have verified this with a Multiplus 12/2000 using the VE.Bus tools in VE.Config.
Try measuring your maximum current draw with a multimeter that captures this to verify this is your problem, or try another 1200W appliance like a 2 slice toaster.
Great answer. Thanks so much for your help.
