Hi Guys,
I have searched the forum for similar questions, but as with most installations the task i have is very specific.
I have to set up a 57kw submersible pump in a offgrid situation. The pump has two starter options Direct on Line and Y/D with respective 535a startup current (DOL) and 173a (Y/D) rated current is 99a
I'm looking at Victron kit as i have multiple 15 kw Quatrros at my disposal. I would be looking at using a 6 x 15 quattro's minimum.
Reading this forum i have read Victron staff confirming that a Delta load is not a problem, especially when using a VFD starter.
Has anyone installed a similar set up? Will using a VFD stop the 178a startup current from overloading the system? keeping the amps within the 99a running current?
rated genset on the pump manual mentions sizing genset 2.3 x kva of the pump which is equal to 131, i could theoretically install 9 x 15kw quattro's to get this closer to this recommendation but i don't think its needed as the oversizing of genset is there in recommendation to handle the surge current on startup.
I appreciate that this is likely the upper end of the inverters capability, but i want to explore this option as much as i can before looking into other solutions.
any help or guidance much appreciated.
Thanks
H
