We had a Prosine
3.0 (Xantrex). It worked, but used a lot of power in standby mode (5 amps!). Made a lot of noise
- acoustic and electrical
. Worst thing is their support. Or should I say lack of support. Awful, awful support system. Put on hold for hours over several days. When I got a person, they didn't know squat, were unfriendly and put me on hold for hours until I finally hung up. I sold it and bought an Outback. Beautiful engineering and when I called the company, the phone
was answered by a real person and I was immediately connected to an actual engineer
who had deep, fundamental understanding of the unit, inverters in general and all sorts of other rich boat wiring
knowledge. The engineer
was eager to talk about inverters, engineering and AC/DC details as long as I wanted to listen. Late last year, the unit blew the FET board, which is most likely the fault of our generator
that had a faulty voltage regulator
at the same time. Their phone
was answered on the second ring and the person who answered was able to help me. Without a worry and without cost to me, Outback overnight shipped me the complete electronic guts (4 boards) with the instructions to swap them all out and send back the old boards at my convenience. They didn't ask when I purchased it, or even consider whether it was actually under warrantee. Didn't ask for a credit card. They seemed most concerned with me having a working inverter as soon as possible. They sent along a field service
manual used by their actual service
reps that was a hoot. I like when a company has a sense of humor
up and down the chain. The design of the unit was impeccable and VERY field serviceable. I was very impressed when I opened it up and found the entire unit can be easily serviced with a few basic tools. No way a lay person can work on the ProSine
units - I don't think they are serviceable at all, but are throw aways.
I wanted a Victron, and agree that these are top notch, but the unit would not fit the space I needed it to go into to. I am very happy with Outback and think they are equivalent engineering to Victron (and less expensive).
When Xantrex bought Trace, the Trace engineers left and formed Outback. Recently, some of these same engineers left Outback and formed Magnum. Magnum wasn't around when I was buying
a new inverter, but looking at them now, they seem to also be a very good choice with good prices.
