Smalle Boat Electronics-12V DC System.pdf
I have installed a system on my boat with Victron Smart LFP batteries, a 120v / 3000w Multiplus, a Cerbo GX, and VE.Bus BMS. I pretty much just followed the schematics on the Victron site, and it is working great. I uploaded my schematic as reference.
Overall, I'm very happy with the system, but I would really like to be able to use my phone to change the Multiplus between Charge/Invert. I can set the current limit, but it won't let me set the mode. That is really annoying and I don't want to have to install the little control panel just to use the switch.
Another thing that seems to be missing is a way to disable the inverter at a certain SOC. I have just enough batteries to run my aircon for a few hours in the evening which is all I need to cool the boat down for a nice sleep. I know I can do that with the MK3 USB interface cable, but its so clunky. Sometimes I would like to be able to turn the inverter off at a different SOC and it would be really nice to not have to use the computer and cable for that.
So, anyone have any ideas on how I could achieve either of these two things?
