Hi Jimmyaz, welcome to, or back to the Forum.
The B17 product line will most probably start at the higher end of the maximum power spectrum, IMO.
It may take MN quite some time to develop a 24 V model, as higher power systems really want to operate at higher battery voltages -- 48V.
The Schneider Conext SW (or whatever they are calling them this month), is an inexpensive inverter. Again, IMO, the B17 is not designed to compete directly with the lower end SW inverters ...
Many of the advantages of the B17 become clear at the high end of the power scale, and the SWEs are not there.
When I tossed out the idea of the B17, realized that it was not exactly in your application ball park ...
