Install of AC Port Inlet with Promariner ProSport 20 Amp 2 Bank on board charger

Recommended Posts

Hi All:

Long time reader but a first time poster. Hello All :)

I am planning to install a Promariner 20 amp 2 bank on board charger on my 2001 235 SSI with a AC cable inlet/port, that is in a slip and will be using shore power to charger.

Are there any of the members here, who might have done this install on a same or similar boat and if so where did you mount the charger and the AC Cable inlet? I have 1 cranking + 1 house battery on the starboard side of the engine compartment and from what I can tell, it is probably the best place to mount the charger. However, not quite sure where will be the best place to mount the AC inlet unit. Doesnt help that as a new boater, I am paranoid about drilling holes on the boat :).

Secondly, I have read a few posts and noticed that some members advised to cut of the AC cable for the charger and screw in the 3 wires into a Marinco AC inlet. I checked on this with Promariner support and they stated that doing so would void the warranty on the unit, if I were to cut off the AC cable to mount the cables into an AC intel. So that is not an option and this brings up my question regarding using an extension cable type AC inlet and if its **safe** in the engine compartment? I have seen the following units (made by NOCO and Journeyman-Pro on Amazon) but unsure if they are safe, since there could be sparks and which could light up the gas vapors in the engine compartment.

Promariner has advised that I use their AC port inlet that passes-through the charger AC cable through the port, however, I am concerned that it might be flimsy and AC cable might not be securely fastened to this type of AC inlet with the clamp type support that is provided.

Any feedback or suggestions are appreciated.

Best Regards.

Are you planning to use this charger off shore power when the boat is in a slip?

Yes, I should have mentioned that the boat is in a slip (edited my post) and I will be plugging it into the shore power outlet.

Thanks!

Than you should be adding a galvanic isolator so your drive is not eaten up. You may want to check with your club or marina if you can use a 20 amp cord to plug in. Some docks will not let you use a 30 to 20 amp adapter unless your on board.  Makes since, the breaker is rated at 30 amps for a shore power cord. The biggest normal extension card is 20 amps and if something where to happen the cord could burn up before the breaker pops.

I have a Noco Gen2 mounted on the port side of my 226 on the engine compartment divider.  That side is where my battery switch is so connecting it was super easy.  I installed a Marinco AC outlet on the port side stern near the radio remote.  I cut the cable on the Noco and hard wired it to the AC outlet.  Couldn't care less if it voids the warranty.  It cheap and if it dies I'll buy another one.  Both the plugs you posted should work OK too.  

If the battery charger is designed properly you shouldn't need an galvanic isolator,  but I would add one to be safe.

YANDINA Galvanic Isolator

You should go with this one ProMariner ProSafe Fail Safe Galvanic Isolator - 30 Amp  https://www.defender.com/product.jsp?name=promariner-prosafe-fail-safe-galvanic-isolator-30-amp&path=-1|328|2290032&id=1353688

First off it is "fail safe" meaning that if the diodes inside fail you still have a ground connection.  Also the Yandina isolator is not ABYC (American Boat and Yacht Council)  AND UL  certified.

Rather then cut the chargers AC end off, you can get a short outdoor extension cable, plug it on to the on-board charger's plug, then cut the end off the end off the extension cable, This works well when the charger outlet is further from the charger, then the charger's AC cable permits. or, go with the Promariner outlet that clamps over the AC plug.

Thank you everyone for your feedback on this. I reached out to Promariner support and they  have advised me that I don't need to have a GI installed for 2-3 months that I will be in the slip as charger is smart enough to not charge when batteries are full. Also, regarding the AC inlet port, I am advised to use the Promariner inlet that clamps over the AC plug so no cutting of the plug/wires will be required.

My main worry from the get go has been the fuel vapor igniting with a charger cable connected to an extension cord and if in case sparks fly, boat wont go up in flames ;). Not sure if this is even an issue, but being a new boater, I would not want to put my family or crew in harm's way. Are my worries logical or I am just over thinking this part?
