$48k? For what?
I did 2 5k systems in phase for 240 volts with a 4 port auto switch and a buck bust auto transformer for a lot less than that.
Are you paying too well? Get me the specific requirements and I'll run real numbers.

Hi Paul,
I'm taking a different approach.
The first Australian owner converted the boat to 3 phase marina power which suited him better.
I'd have preferred the boat not have 3 phase shore power. The Phasor genset is single phase.
All of the power points and AC lights now have their own modern circuit breakers in the wheelhouse and the AC panels for these particular circuits in the engine rooms are bypassed. We also have a 12 volt 1200w inverter that can adequately power the lights and power points and big 240 volt fridge via a separate 12 volt battery system. The 12 volt battery system is charged by a 32v to 12v DC battery charger. This all works but is not ideal. The DC charger seems to zap too much energy from the 32 volt port battery bank and may well be part of the issue with the lead acid batteries.
Thus, my issue is I use/flatten the 8 x 8 volt port bank starter/house bank often enough to hurt the batteries. I cant charge them adequately on the swing mooring. I've managed to flatten the port side twice this year and they are not recovering.
So my 2019/2020 idea is to remove the old broken Kohler genset, install a Victron Multiplus 48 volt lithium inverter charger $2000, buy as big a 48v/200amp volt battery as money allows ($6000?) to wire into the revised power points, TV and fridge circuit.
Everything else DC can stay on the existing 32 volt port batteries. The only critical DC requirement from the port batteries would be the bilge pumps. I'll also replace the horrid Rule float switches that moved and got stuck open and thus flattened the batteries.
Look at victrons 200 ah LiFePo batteries. 4 will give you the 48 volts and they charge much more efficiently than any lead acid. Also they have an 80% duty cycle and dont need to be topped off every time.
After painful analysis paralysis, I've decided to leave my Ono 20kw in place, and simply add the new 16EKOZD as a second generator. The Ono works well, other than being noisey, and just can't see removing it at this point. So, we're about ready to make some noise. All these boats are a little different and access varies. My genset hatch is huge compared to others. 30" x 48"
