run the UPS side fully isolated from the line via the inverter, so no surprises, because the system is always running via the batteries,
That's supposedly what this unit does. It won't even power up anything unless the batteries are good.
So what do you have there, a kw or so of ocmputers? Adds a whole new meaning to "electric home heating system".
I just measured it, 650W to the UPS on the old Maytag wattmeter. Should have handled it fine, and it did when moving the plug to and from the Maytag. Something about the nature of the power spiking the other day really PO'd it, and me too. -- Jim
