Hi Folks,
I have read lots of threads on the subject but I still have an unanswered question if I may,
3 BATTERY BANKS - All Rolls AGM. Starter is 100ah Rolls x 2 (24v) Domestic and Bow banks are 2 X Rolls 230ah each set up in series for 24v.
Starter and domestic banks are next to each other and only 1 meter from the engine so no issues.
Bow bank is however almost 10 meters from the alternator and domestic bank - so potential issues with cable length in emergency cross-connection.
I have read Paul Rainbow's suggestion of 3 - output shore charger and 3 output Argofet and that appeals as a simple solution but is that the best way to get power over the 10 meter distance?
The charger is comparatively easy as I could position it at mid-point and still stay within the maximum 6 meter cable length advised by Victron - but the alternator output (via Argofet) might be more problematic.
Would I be better fitting a second charger up in the bow and feed that with 240v from the Victron inverter (3KW) which could in turn be supplied from the alternator via domestic bank i.e. Use 240v to go the 10 meters rather than 24v? That still leaves the issue of emergency DC cross connection though?
Thanks in advance for your thoughts.
Steve
