We are having an issue with a customer. he rented a 208V-3ph unit from us and when the onsite technician hooked up the generator, he said the inverters blew up instantaneously and there was been some spoke going out of the unit from what they have told us. This is a unit with 6x Quattro 5kVA 120V inverters
The technician on site insist that the generator was switched to 240V 3Ph but I really suspect the generator was set up to 480V and that is why the inverters blew instantaneously. We do not want to start a fight with the client as it is potentially a big customer for us but we need to be able to prove that the fault is on their side. there is no alarm on the VRM unfortunately. My questions are:
- If a 208V unit is hooked to a 240V generator, can the inverters blow up?
- In case that doesn’t and the generator was switched to 480V, Is there any specific component that will only blow up at 480V that can prove this?
I will really appreciate some help on this. We have got 6 inverters damaged and this is an important client that we do not want a fight with but we want to prove them that this was due to a negligence
