I have a 24 v system and would not go back to 12v. Most major draws, heaters, stoves, and even fans have 24v options negating the need for buck converters. Yes I have some 12 v hook ups but 24 to 12 v converters are cheap and plentiful. 24 v is the future as more power is becoming available. Check out the packaged solutions from watts24.com...smaller, cheaper, and better than comparable Victron systems. Victron is great but you pay for it and in most cases there are good enough options
