I'm living on my sailboat, equipped with a Victron Quattro 12V/220V/3000W and a marine Genset. I'm actually trying to find a way to start my diving compressor, which is a 220V single phase motor 2.2kw, his starting current peak is about 45A.
My genset is a small model, and himself He's not able to provide enough to compensate the Starting peak current demand. So i connect the genset with the Quattro and in theory the genset power + the power assist should be enough to start this diving compressor. But it's not working, i first believe it's because my genset is really to small, but in fact not. See below another test i did and please if you have any suggestion don't hesitate to answer.
When i connect this diving compressor directly to the 220V/16A outlet of the harbor, the diving compressor start and run perfectly.
When i connect this 220V/16A outlet to my "AC in" of the Quattro and the diving compressor is connected to the "AC out", the diving compressor is not able to start! If I'm right, the Diving compressor should be able to start as the Harbor outlet is able to do it, and at least if a little Amps is required for the starting peak, the Quattro should be providing it and the total of this both current should allow the start of the diving compressor. But it's not doing it, I can just hear the Diving compressor motor "growling" but not more!
Do you know if there is any parameter(s)that i should adjust in the Quattro, to allow the full Shore outlet going into the AC out, or if there is a "protection timer" to adjust or something like that ?
Because actually i don't understand if the Quattro is absorbing power of the outlet shore and from that the AC out is not strong enough to start my compressor. Or if the Quattro is stopping the current by the configuration of a thermical protection, timer protection or any "protection" that limit the AC out !
Thank you very much for all the suggestions and ideas that you can offer.
