I've been looking at all the possible options to get a 48/10000 solution with two AC inputs (generator and shoreline) including 2 parallel 48/5000 units and using MPII with ATS instead of Quattro, and noticed some strange price differences (from 2023Q1 EUR price list)...
One is that there seems to be a bigger price premium going from Multiplus to Quattro with the new units than the old ones -- for example at 48/5000 Quattro costs 18% more than Multiplus but Quattro II costs 30% more than Multiplus II. Could this be due to the extra anti-islanding relays to meet grid codes in the II versions?
The other is that the bigger units are cheaper per kW with the old versions (as expected) but *more* expensive with the new ones -- for example a Quattro 48/10000 is 21% cheaper than (2x) 48/5000, but with Multiplus II a single 48/10000 costs 11% *more* than (2x) 48/5000. This makes no sense at all...
Anyone got any ideas what on earth is going on?
I was looking at choosing between a MP II 48/10000 + ATS (available now, pain to control) and waiting (hopefully) for the Quattro II 48/10000 to appear, but all this suggests I might as well go for 2 parallel Quattro II 48/5000 which are available now and are likely to be cheaper than a single Quattro II 48/10000 -- and give me some redundancy in case of a failure (though reconfiguration would be needed).
Any comments?
