I have 2 x 55 Watt semi flexible and 2 x 100 watt non flexible panels on the top of my hard dodger
These are connected to my house bank via a Pro Star 30 amp controller. I am in the NW Caribbean
. I also have an old Ampair wind generator
as well which produces no more than 4 amps on a good day. I have 3 x 120 Amp/Hr 12 volt batteries
in the house bank.
The last 50 watt panel is mounted in the stern gantry and connected via a different controller to both the house and engine batteries
. This means when I leave the boat
, I can turn the main array off and just have both banks trickle charged
I will normally see up to 10 amps coming in during the day, sometimes peaking at 16 Amps. (At the moment I am at anchor
in southern Belize
and it is 09:00am, I am seeing 6.3 amps coming in)
I can and have run for months at anchor in the tropics without running my engine
to charge the batteries. On a sunny day we are dumping electrify by the afternoon but more than 3 cloudy windless days in a row and we are struggling
I have all LED lighting
below, 2 x Calframo fans running on low speed 24/7, a fridge (Danfoss BD50 running at low speed only) which has had a new very efficient heavily insulated box built for it
Hope this helps
