I have some data. I ran the boat with the charging system plugged into the Westinghouse generator. But, I forgot my laptop and so couldn't reprogram the charger for full output. It is set at 1000W

Re: Recommendation for 48 v inboard motor + generator.
Not yet. I have only been in the water and rigged for a bit over a week. We also haven't had the right conditions for such a test which has been great for sailing. But thanks for the reminder. I

Re: Need smart people help

Re: Need smart people help
I use a pair of Meanwell HLG-600H-54A chargers for my 10kWh pack (16S LFP). It tops out at just over 58V, but that's fine.? They draw ~700W each, so four of those would just use up the 3kW your
