You also left a galvanic isolator out of the diagram. See http://promariner.com/products/galvanic-isolation/prosafefs-series/
These keep you from sharing your zinc out to the entire marina ;) Joe Della Barba j...@dellabarba.com <mailto:j...@dellabarba.com> Coquina From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Joe Della Barba via CnC-List Sent: Sunday, March 29, 2015 11:30 AM To: cnc-list@cnc-list.com Subject: Re: Stus-List New Wiring Diagram Draft It has been a while since solar panels needed load dumps - modern controllers are much much better. That said, if it were me I would NOT use the controller you have in your diagram. There are very poor versions of solar controllers all over Fleabay and Amazon that are inefficient at best. Morning Star controllers are much better than the cheap Chinese knockoffs. I have a low end Morningstar PWM controller that works quite well - http://www.amazon.com/SunGuard-SG-4-Controller-Regulator-Morningstar/dp/B000 O3O0W2/ref=sr_1_2?ie=UTF8 <http://www.amazon.com/SunGuard-SG-4-Controller-Regulator-Morningstar/dp/B00 0O3O0W2/ref=sr_1_2?ie=UTF8&qid=1427642561&sr=8-2&keywords=morningstar+solar> &qid=1427642561&sr=8-2&keywords=morningstar+solar - and it isn't even that expensive. I am considering moving to a more expensive MPPT controller and bigger panels. The MPPT controllers - if they are the real deal and not cheapies with a fake label - are quite a bit more efficient. See http://www.morningstarcorp.com/wp-content/uploads/2014/02/Morningstar-Corpor ation-Traditional-PWM-vs-TrakStar-MPPT-Whitepaper-March-2015.pdf . I also would not try and use a "dual controller" to send solar to the start bank. 99% of the time the start battery gets about 2% discharged at engine start and is quickly refilled. Usually solar just feeds the house bank. If you want to charge the start bank, use the combiner. I don't know if the charger you have on your diagram is the actual one you are going to use, but there are better ones out now. I have that same one and it is going on EBay. I got a Promariner Pronautic with a temperature sensor that is much better for gels. I could not find a sensor for the old TruCharge and it does not charge at a high enough voltage in the very cold weather we had even on the cold setting.

They are just resistive loads. You can get 12v heater pads that you can attach to the water tanks or heater. You could also install a block heater in the engine. Most block heaters are designed to be plugged into a wall outlet but for a dump load the current and voltage are way lower than the rating on the heater.

Here is link to my draft setup: https://dl.dropboxusercontent.com/u/15162917/ENTERPRISE/EnterpriseWiring-Dra ft.pdf Very crude I know and probably could be considered a mess by any respectful wiring diagram standards.
