Victron and Ecoworthy

from this post:

Victron and ecoworthy solar controllers should not be lumped together

I lump them together in the “things that work” category.

The former is very up to date, well designed, precision engineered and tremendous build quality, worldwide 5-year warranty and very widely used in marine installs.

Not everyone needs precision engineered and tremendous build quality as found in marine installs (for 3x the price).

As long as one is overpaying, why stop arbitarily at marine grade?  Why not avionics grade or aerospace grade?  Why not spend $5,000 on something you could get for $150 (Victron, made in India) or $60 (Tracer, made in China)?
