wiring of charging - review needed

guys,

on my Cape Dory 28 I intend to wire a new schema for charging ... below is my idea of the new concept and I would appreciate your comments/ideas

- two deep cycle batteries - engine and house battery
- 3 way switch -1/2/both/off
- no shore cord or shore charger

alternator output plus wire connected to selenoid on starter motor which is in turn wired to the 3 way switch and then corresponding battery

then I have solar panel and wind generator connected to blue solar charge controller
- BlueSolar MPPT 75/15 - Victron Energy

this contoller I plan to wire to the house battery

then I have intelligent battery combiner wired between positive terminals of both batteries
- Victron Cyrix Intelligent Battery Combiners

this setup should work in my view as follows:
- I crank the engine using only engine battery (position 2 on switch) - in this way the battery should be always fully charged ... if so, thanks to the battery combiner the house battery should get also some charge ... this is the most important aspect for me, to have engine battery always fully charged obviously
- if Im on the anchor I switch only to the house battery to be used
- the house battery gets charge through solars and wind generator and when its fully charged the engine battery gets also some charge through the battery combiner

how does this scenario sound to you? thank you very much for any suggestions, tomas

Run the alternator output to the house bank, NOT thru the switch.

Re: wiring of charging - review needed

the last question is about battery - I like the concept of one battery for both engine starting and house load ... and the second battery as backup ... however then, which batteries should I use? what I mean is that for starting battery I should use cranking (ie automotive right?) battery which is capable of providing big but short boost of current while for house loads the deep cycle should be used ... how to deal with that dilema?

Im about to buy a new batteries as the ones that came with the boat are dead and engine doesnt crank on
