I'm looking to land somewhere around 200A for the alternator. I'm planning on replacing my batteries in the spring with a LifePO4
pack so I could even go up to 300A. (I did the math on this and the total cost per AH per year is less than half of Lead Acid when accounting for initial cost and generator run time). I want to be able to do 150-200A at 1800RPM.
Looking to land around 45-60GPH on the watermaker
Found a single
4" Flimtec membrane and pressure vessel at WaterSurplus that should make upwards of 80 GPH when paired with a D-10 at the same or lower cost than the typical 2.5" dual vessel arrangements that you typically see.
With my Z482, I should be able to generate around 200A while running the watermaker
at about 3000RPM. Dropping down to 1800RPM I can run one or the other for quieter operation. Reduced water output but can keep the amps up if not making water.
Essentially this should allow me to run at 3000RPM for the first 30 minutes or so making water and amps, then down to 1800 for the next hour or so to top up the batteries. Way less time than required with the longer charge times on Lead Acid batteries!
