Cummins Diesel Query & Reviews

Good day, gents

The 15kva reads, in cylinder reduction for emissions vs the 25kva and up units that read in cylinder + after exhaust treatment for emissions. No AdBlue mentioned. They are both prime generators meeting the latest emission norms.

What are the differences, and are they significant enough to warrant the extra cost in getting the bigger unit? wet stacking = manageable

I went down this rabbit hole with an initial Max load of 4700w. Looked at Honda inverter (30is / 70is), off grid solar and standby units.
