Charging gear

Apologies for the n00b question, this is our first RV.

We just bought a 2017 Sunseeker 3050S. I want to be able to charge while at home (or somewhere that only has a standard house 15amp circuit).

I was thinking of purchasing 2x50ft 10/3 extension cords (only using both if I have to), a 15amp male to 30 amp female adapter, and a 30 amp surge protector, which will then connect to our RV cable.

Do I need to worry about overcharging? I canít find anything about if and how the 3050S handles this. Iíd rather not buy a trickle charger if I donít have to.

Thanks in advance, forum gurus!

Just plug your rv in. The onboard charger will not overcharge.

Look into the 30amp extension cords before you buy a 15 amp. Maybe a similar investment and we have needed additional cording at some campgrounds.

Don't waste your money on a surge protector. Buy an EMS. Much more protection. You will find more low voltage then you will find surges.

I assume you are talking about regular RV type extension cords. Get one long enough to meet your needs where you store your RV rather than several shorter ones. More connections, more problems.

For the adapter, get a short pigtail with 30 amp female on one end and 15 amp male on other. This will reduce the common problems with the "Hockey Puck" type adapters, each side of it having enough resistance to cause some heat, which then adds together to enough the "rubber" melts. The pigtail adapter only has a little heat on each end that dissipates quickly under normal circumstances. If you do "toast" one, the pigtails are cheaper than the long cords.

Shop around. Lots of offerings at lots of prices for RV extension cords.

Wow thanks for the great help! Yíall are already saving us time and money!

I will skip the surge protector and look for an EMS.

I did buy a pigtail adapter, so I think Iím good there (depending on the ext. cord discussion...).

On the extension cords, I was thinking of the 15 amp non-RV cords:
- When we are home: RV -> RV cord -> EMS -> adapter -> ext. cord -> house.
- When on the road: RV -> RV cord -> EMS -> power.

But looking at that and hondamanís comment about needing more RV cord length, perhaps I should buy one 50ft 30 amp RV cord, and one 15 amp cord.

Yíall rock!

Also when continuously plugged in, monitor battery electrolyte levels and keep them topped off. My experience has been every battery charger/maintainer no matter the quality will affect electrolyte levels.

If you have a Progressive Dynamics type converter they typically come with a standard power cord that plugs into a standard wall receptacle. If yours is conveniently located you could just use your 10/3 extension cable and plug just the converter in for charging. Everything AC voltage will not even be powered. Just a thought.

your original plan is just fine - dont worry about surge or ems and such, just plug it in and let it keep your batteries charged...simple

Yes I keep a 50 ft 15 amp cord also to run an electric space heater right off the pedestal

The forum is the place to get answers.

You should have a Progressive Dynamics converter/charger in your power bay where your 30a power cord is stored.

Picture of my Progressive Dynamics converter/charger.

If you only want to charge your extension cord should work. Do not disconnect the battery, the Progressive Dynamics will not charge your battery with the battery disconnected.

If you plug into a GFI outlet it may trip. That is because you have a GFCI outlet in your Sunseeker. You can turn off the GFCI outlet in your Sunseeker 120v Circuit breaker. After that you should be able to plug in the shore power cord without tripping GFCI. For your own protection, you should not plug an outside extension cord into a non-GFCI outlet. Also do not let the ends of the extension cord touch the ground.

There are many threads on this forum about hardwired an portable EMS & surge protectors. My choice was to mounted mine inside my power bay. That way I can use it to test a CG pedestal & not leave it behind.
