This project was delayed and updated: - using LiFePo4 cells instead of replacement battery pack - using REC 2Q BMS with precharge and Victron support (CAN) - using Wakespeed WS500 alternator regulator with Victron support (CAN) - using 2x Victron DC-DC 9A chargers for maintenance/charging of...

I have now finalised the design - high-resolution PDF is here: What has changed: - TBS 300A T-class main fuse - using TBS Battery Protect Relay as main charge/discharge disconnect - TBS positive bus bar for load + chargers - REC ABMS main relay is connected to REC Precharge that does...

@svagres: I agree regarding windlass. It is hooked to service battery as windlass was basic equipment and bow-thruster was an option that came with own battery. They still hook windlass to service battery. I will probably rewire windlass to bow battery. Solar disconnect: misunderstood it at...

I will first try with current connection of windlass to service battery - with 550Ah and REC BMS I do not expect it to trip the BMS to shutdown the LFP battery. Bowthruster will stay on lead-acid for now, I use it rarely. I might later upgrade to LFP bank also for bow battery and then I could...

I have a 42" sailboat with 3 lead acid battery banks (starter, bow and house) + 560W solar system. I mainly use the boat without 220V connection (max once a week), with limited engine use (0.5-1 hour / day). Solar currently provides enough charge for my daily use. I currently have temporary...

SOK support confirmed that putting on side should be fine also for marine environment.

Regarding solar disconnect: they are connected with MC4 plugs that can be used as safety disconnect. But will discuss with electrician about standard requirements.

But I would suspect side mounting could be problematic when a sailboat heels, at least for some time you might get them upside-down (angled).

Sorry for re-opening the old thread, but I have a question regarding the manual disconnect of inverter/charger. Why do you need it (as you already have smart disconnect + override with 7713)? How do you handle pre-charge when manual switch is used?
