Hi, finally back in harbour - intrigued as to why you say that charging the 72v won't make much difference as they should keep the house fully charged automatically (maybe with some losses). My thoughts were that charging the 72v (ganging 6 panels
in series) will effectively reduce the impact of the solar
panels on the energy management system so my thinking (not checked with anyone who would know) is that you charge the 72 volt trying to keep them above 80% as long as possible so the generator
doesn't kick in. I am mainly thinking about anchoring
for this. You should be able to pump in just as many watt hours or amp hours this way - but I have only just started looking so will keep you up to date with what I find out. What do you think about this approach?
The scarey thing is I have just calculated my power usage with the way we have configured the boat - nice and comfortable - and it is big. I am looking at new LEDs for the saloon
and also the anchor
light as a start. I have also seen some solar panels that are long, not so wide and could be mounted on the top of the hull
outside the lifelines
that may work well. Will let you know.
On the tachos - I have done little on this but the description was a "read switch on each shaft feeding back to tachos on the helm
- doesn't help much I know but again will give further details as I find out more.
So I think I have said alot but given little information and will come back with more as I get it.
By the way G2 is scheduled for me this week
