I am planning a system that will use the multiplus 12/3000/120. A lot of time has gone into reviewing the details but I'm still concerned about running the equipment on the multiplus without causing damage.
The equipment in question is a magnetic stimulation therapy device that has a max power consumption rating of 2700va, operated from 120v via a 120-230v transformer. The machine requires a 20 amp outlet.
We ran the unit for 7 days straight for about 40 minutes at a time, with a varying number of clients. The unit generally ran at a power factor of .7 and pulls an average current of 3.6 amps. In the course of a seven client day it consumed roughly 1kw of energy.
The main concern is there is a chance of damaging the equipment if the power supply shuts off when in use. We are using 510ah of lithium batteries to power the multiplus, and there should be plenty of energy on reserve.
Having crunched the numbers my biggest concern is the peak power rating. The inverter will be in a climate controlled environment, theoretically. However, if the multiplus is operating at a higher temperature and it's output derates, it may not leave much margin for the equipment to hit peak power.
We don't really have any data to say how long the equipment operates at max power. The multiplus' peak power rating does seem to indicate that it would handle it just fine.
But is there something I am missing? Can anyone weigh in on this topic?
