I'm planing a single phase system in Nepal at the moment. A question I'm asking myself all the time is if I should go with a single 15kVA Quattro or 3x 5kVA Multiplus II units.
What will be the downside of the 15kVA Quattro in comparison to the 3x Multiplus besides of "redundancy" in case of a faulty device?
15kva all the way. No downside here (unless you have grid compliance requirements)
The parallel multi2s are more likely to be a huge headache for setup as well.
+1 Quattro have higher overload capabilities
+2 uses the same size battery bank.
+3 easier to install
+4 proven reliable product
If installed properly you will have zero issues on the Quattros. Have seen/inspected some recently that were installed over 10 years ago.
