Hello fellow TFers.
In a recent post I mentioned that I plan to add a second house battery bank.
Context: I currently have 1 house bank, made of 2 group 31 batteries, 105Ah each, and 1 separate starting battery for my single engine. These are charged using 1 dual charger (25 amp) and 1 alternator.
Issue: While I have a small energy footprint, the house bank capacity is a bit too low. I spent most of the time 2 to 3 days at anchor. The main energy burn comes from the fridge, the remaining is only lights and radio.
My plan: I would like to add a second house bank made of 4 GC2 batteries. This second bank would be used solely for the fridge while the initial bank will be used for lights and bilge pumps, fresh water pump, head etc... This should allow me to have 48h capacity without running the genset.
Now some questions:
Should I install a second charger for this house bank as my current charger already connect to start and initial house bank?
Would a single alternator enough for 2 house bank and the start battery? ( I would like to avoid installing a second alternator).
Any advice or comment on what I plan to do?
Any comment welcome
