simple system to do most of wind/solar/alternator/shore to house/starting/dump + more
I've been looking all over Sailnet and searching the web, and could use some input form the experts/experienced people here.
I'm setting up my fourwinds wind generator and plan to add solar eventually. The boat will be unattended for days at a time, so the wind gen will need a dump load. (No one there to tie the tail off the wind or throw a stop switch.)
Ideally, the system would have these features:
Accept power from
1) wind generator (fourwinds II)
2) Solar panels (maybe 500 watts eventually)
3) 2 x Engine Alternators (currently a separate one for starting, why not somehow put it to use when running the engine for charging?) I think means something that boosts to overcome internal resistanc eof the batteries.
4) Ideally shore power, although I have a 3-stage shore power charger in place already.
1) House bank of 2x4D (eventually 4x4D) -- gel batteries
2) Engine starting battery -- wet cell
3) Temperature sensor to keep batteries happy
Inverter for 110v
1) 2500 or 3000 watts
2) remote on/off
3) Automatic switching from battery to shore power.
4) Ideally a way to separate off non-essential 110v if the shore cable comes unplugged. For instance, so the A/C doesn't drain the house batteries to zero when I'm away. (Not that I have A/C. It's an example.)
1) Handle dump load to water heater (2 cascading dump loads if possible)
2) Eventually measure and display amphours in/out/remaining in house bank
Anyone have any ideas if there is a single device that does most of this, or maybe a collection of devices that would do most of this?
