The simplicity of skipping shore power entirely is very appealing right now, as I'm just starting a Charles 3.8 KVA (IsoG2) installation
. No real choice here in the Pacific Northwest
in a boat with lots of systems and development tools, though once the 420-watt solar array is installed (along with the existing 7.5 KW genset) I will skip the cord more and more.
Having said that, I'll offer a couple of other comments. I have a steel
boat that came with a Newmar galvanic isolator. I'm not aware of any problems, but zinc loss has been variable depending on the marinas
... so I've opted for the fancy solution that seems to be well recognized as the most robust. The hassle at the moment is that the existing wiring
is complex and not well-documented: breakers and distribution in different panels
6 feet apart, obscure wiring to source-select and automatic changeover relay (which should now be irrelevant with new Outback inverter/charger), and very difficult access to the shore power inlet where I need to place a new main breaker.
But yes... once I finish making the ship even *more* complicated, I look forward to minimizing shore power use. I've just moved to a famously hot marina, so there's a bit of urgency around this at the moment.
BTW, I haven't fired it up yet, but have been very impressed with direct telephone tech support from Charles. They never answered a pre-sales email
, but when I called to ask a couple of engineering questions I got an immediate and friendly response.
