Hi Foster

You have the nice arch!

Used 10awg wire and distance from panel to controller is 7 ft; distance from controller to battery under rear bunk is six feet. We checked volatge using digital voltmeter at panels then at controller and had no discernible loss.Checked voltage at output on controller then at battery lead and there was no voltage drop.

These panels are rated at 17.1 volts but I have had readings of 20.1 volts each. We used the morningstar ps30 pwm controller. If I did it again I would get a good mppt controller vs pwm but this controller is doing fine so far. Wired in parallel configuration.

This configuration keeps our 2 4d agm's juiced. The beer is cold, batteries are full, captains happy!

Hello James,

Nice to have such good electricity input.

Would you have some detail on the regulator and the connections from the panels to the batteries. (Size and length of the wires)

thank you.

Just returned from weekend on B43 with 2 140 watt Kyocera solar panels (above bimini, anthwartship) charging two 4d 200ah (each) agm batteries(pwm controller)). 

This was our first outing with the panels installed. As we entered Bay we shutoff engines and sailed 3-4 hours using auto pilot from time to time. Energy hogging refrig, freezer, and chartplotter (e120 wide) were on entire time. Anchored boat, had guest arrive and used lots of interior lights (leds,) anchor light (led) windlass,flushes (two electric heads), electric winches etc. Numerous refrig/ freezer door openings during evening and into night. battery voltage at Linklite monitor never dropped below 12.4/5 volts (overnight and evening usage). Three hours partial sunshine in morning we were seeing battery with 13.3 voltage acceptance and above 92% charged. Definite improvement. Had there been totally sunny morning I am quite sure the batteries would have been topped off in 3-4 hours. I  think this will prove to be a very worthwhile improvement since we anchor and moor quite often.

We will be at the Rendevous.

If you're going to be in the Chesapeake area in late May/early June the Beneteau Renezvous is always a good time! Well worth the trip!!

hi everybody and happy new year

Am I correct that Beneteau constructs its hulls by joining two halves together.If so, seems vulnerable. Also I am a techno challenged new member. How do I send this to the forum members?

There is a mechanical lock that should separate the Inverter from the Dock AC curent. I am being overly cautious to make sure Beneteau actually did that with the mechanical switch. 

Blue Sea makes a switch that has one input for the generator ac power and two outputs which I will use for the House AC and the Air Conditioning AC circuits. I want to be over cautious to make sure that the generator output can never interact with shore power.

Comment by Bruce Bogdanoff on January 14, 2012 at 3:52pm

Thanks for the diagram, ogdrum. It helps. Why I wanted a AC circuit diagram is that I am going to install a 5.5kw generator and I want to make sure how to wire the generator into the ac circuits. I have two AC circuits, boat and and air conditioner. The boat AC circuit has an inveter in it that is not indicatedon your schematic. I want to confirm that the inverter/dock ac switch totaly isolates the dock current from the inverter with no possibility human failure to turn something on or off that will allow the two circuits to ineract with one another.

Does anyone have a detail wiring schematic for the AC circuits on a Ben 40. Thanks

B43 wheel leather

Does anyone know what the actual color of the wheel covering is? Mine needs a little T&C, some leather dye, not sure if its dark red or something else? Want to match it first try.ThanksSee More
