DC/DC charger 48VDC to 12VDC

In the product list there is nice DC/DC chargers for 12/24VDC input and 12/24VDC output.
How about to extend these product offerings with 48VDC input and 12VDC output, preferable isolated?

Hi,

They exist. 3 models available:

By the way, the tag MPPT - Solar Charge Controller does not fit for this product/question.

The orion models referenced in the link are not chargers, they are simply converters. They aren't 'smart' and can't be configured with the charging profile of the 12V battery, unfortunately.

Hi. I've been hoping that Victron would offer a smart 48V-12V charger such as discussed. Hunting around with Google I found a product made in the UK that looks promising: https://www.ebay.com/itm/330932593423

Couldn't you use an MPPT SmartSolar converter for this? The 48V source woul just replace the PV panel.


I'm interested as I have a 1.2kW 48V battery that I'd like to use to boost my 12V yacht power when sailing at night.

OK if we use the MPPT as charger for the 12v Battery, is it possible to set it in the GX list as a charger so that its production is not added to the Solar panel kind of what we do ( reverse) with a battery monitor set as a Solar charger?
