New marine install
Greetings, I am installing the following system in a boat and would appreciate any input/comments. The boat has no generator or solar panels.
I have 6 Renogy 170AH batteries paralleled (1020 AH @12 volts) to a 2000 watt pure sine wave inverter/charger. Inverter mfg. recommends 1/0 wire with a 200 amp fuse. I also purchased a 40 amp DC to DC charger from Renogy to help keep the batteries charged while underway with the inboard boat engines (2- 80 amp alternators). The system will supply limited house bank power to the 12 volt systems on the boat and primarily supply the inverter for 120 volt A/C power. The expected draw on the inverter will be 700-1000 watts.
If needed, I can increase the alternator amperage with a replacement alternator, but as the DC to DC charger is only 40 amps, I don't believe this will be necessary.
I also read on the forums that the batteries should be connected with the same length wire to a bus bar or at least have the pos and neg connections on either end of the bank. With the batteries having their own BMS individually, is this still important?
Thanks in advance!
