The boat? 1973 Ericson 46. It. Is. Yuge.
Currently, it has an older Xantrex 2000w inverter/charger. Sadly, It doesn't support lithium charging profiles.
Here's what I'm leaning toward:
Multiplus 12/3000 (110v) Inverter Charger. (May add a 230v auto transformer on the input later on)
I have a 3k on my camper and love it.
I'll drop in a AGM on the engine starter side and use it as a buffer to provide a high amp charger source when the engine is up. I'm looking into a 175A alternator kit.
For solar, I'm hoping to get 3-4 350-400w panels on my Bimini. I have a pretty deep cockpit and will extend the rear pair over the stern a bit. I will probably run a SCC per panel or two to keep the watts down. Victron MPPTs all the way there.
I had an interesting conversation with someone who has panels mounted upside down so they can flip out - he reported 85% output from reflected light! He doesn't even bother flipping them out and just leaves them where they are. It could be an interesting way to add capacity on limited surface areas like the monohulls.
Battery wise, I'm just trying to decide how much $$ to throw at it. I'm torn between 16 and 32 cells, probably on the 280ah side. I guess I'll spreadsheet it up again but last time I did the difference between $/Ah was minimal for say 100-200-280 cells.
I've been using SMBS0 on my camper. I may continue with it, but it does require higher end SCCs that support remote control. I may opt for something different. One issue I'm pondering is if I can build out a pair of packs on each side of the boat.. I figure that would take a pair of BMS and I *know* that Dacian doesn't want to support that on the SBMS0.
Like my camper, I'll network it all to a raspberry pi running the venus image.
Edit: I may go ahead and add a couple of DC-DC converters between the starter and the lithium bank. More money but better charge profiles and can be bypassed in a pinch at 12v.
