Hilooks great to this newbie. I sent you message to ask some questions. I really like how you still have 12V after upgrading to 48V. I plan on doing the same and feeding the 12 V fridge and freezer with 48V - 12V converter and windlass an leaving all 12V as is on its own system charged from 48V to 12V dc to dc charger.
What do you have today ? Assume you already have a 12v circuit with 12v only devices (windlass, etc) ?I am trying to draw or configure a diagram but am not getting anywhere with a website or program. I still have pen and paper. I have called a handful of marine electricians and they all try to convince me of going 12 V everything and have a separate panel for the items I want to run.
Yea I am playing with 24v because my fridge freezer compressor are dual 12v 24v. I plan on keeping small 400ah 12 V system and 1600 ah 24v or 48v system. Trying to find someone help me with these things is like pulling teeth. Most are brainwashed at 12vWhat do you have today ? Assume you already have a 12v circuit with 12v only devices (windlass, etc) ?
If not then consider 24v!
Im going 48v as the charger/inverters ONLY support 48v battery banks, hence why i need to step down convertor to feed my existing 12v system.
However i am trying to remove much of the 12v devices (but not all), a perfect example are the fridge and freezer. Going to replace those with 110v standard home models. Also replacing the French standards oven and stove with 110v electrical models. to mention a few things. My windlass, electric winches etc are 12v so still need to keep that system running, and would rather not spend more money replacing those items that are working just fine.
