What do you call a "large genset" and what is the range of light gensets that you are considering?
Thanks. The Cuisair would not work for me as I have to cool two cabins on each side, but often only one per side. The system would be under utilized when only cooling
one. Also i would have to run large diameter air ducting along the length of the hull
if i install one per side. Laggoon's approach is to put one 8K BTU Cruisair per cabin
and one 16 K BTU in the salon
. But then you use a lot of storage
space under the beds and the noise
next to your ear prevents from from having a good night sleep.
A large genset for me is one that provides more power than I can use for charging
. Anything over 2.5-3 KW in my case, as I will very rarely use it. I used my portable Honda
only during crossing the Atlantic. It sat unused in a locker for over 6 months during our trip. during the crossing the weather
was really bad with up to 5m (15ft) swell and 2m (7ft) wind
waves. With that the autopilot
was struggling really hard drawing a lot of power. I
We managed overnight passages with just solar
only possible during summer time and with benign weather
. The new system will have three times the amount of available battery
capacity and 50% more solar
. So all I need the genset for is the very odd occasion of hot and humid weather with long nights or cloudy days. It just does not make sense for me to lug around a few extra hundred pounds of metal and waste perfectly good storage
. A large genset would make fender
storage very inconvenient on our cat.
Does anybody have experience with the chiller driven by a VFD ?
