Re: [electricboats] Recommendation for Charging 12v House Battery from 48v Bank

The Meanwell DDR-480C-12 looks like it will work, although it's not specifically a charger, it does have current-limited output.

https://www.meanwell-web.com/content/files/pdfs/productPdfs/MW/DDR-480/DDR-480-spec.pdf

Tops out at 14V though, which usually suffices for 4S LFP.

They can be paralleled in case 34A isn't enough.

Re: [electricboats] Recommendation for Charging 12v House Battery from 48v Bank

We also installing a 48vdc propulsion bank 600ah and charging the 12vdc from the 48 pack. Recommendation from Victron was to use a MPPT solar charger feed from the 48vdc connected to the Cerbo GX for system monitoring, so we have installed a 100/50 for the LiFePO4 300ah house bank, and a second MPPT 75/15 to the 50ah AGM davit crane battery. None are operational yet, but we trust what victron have recommended.

Cheers

[electricboats] Recommendation for Charging 12v House Battery from 48v Bank

I have the battery box for my 48vdc 200ah main bank installed and am considering how best to keep my 12 vdc house battery charged. All batteries in my system are LiFePO4. I will maintain charge in the main bank with 400 W of solar and a back up generator if necessary but, as my solar array will be 48v nominal I’m trying to  decide how best to keep my 12vdc house battery charged. I had been thinking of one of the Victron Orion dc-dc converters but just noticed in the literature that Victron says that these units are not for battery charging. I’d like to be able to use the main bank as a full time source for the house, but would appreciate any suggestions on what I can use to continuously feed from my main bank to my house battery.

Thanks in advance.
