[PSUBS-MAILIST] 48VDC generator

[Jeff White via Personal_Submersibles]

 Brian:
Instead of an inflatable, I was thinking of making a pontoon boat that could be broken down and carried in the back of a pickup (2 pontoons per side to make a 15 - 16 ft long boat)  and use it as a surface support craft,   Generator, communication system, outboards.    Possibly have it where the pontoons straddle the submersible and can push it on the surface.       
Thoughts?

 Hank,    I remember you talking about that,  I was thinking of getting a dedicated 48 vdc generator and hooking into the battery bank through the hatch and then disconnecting to submerge. Brian

 Brian,That was my plan at one time also, I was going to use alternators with internal regulators.  It should work, but I am not sure how long the alternators will last if they are not sized correctly.Hank

 Hi All,                     Does anyone know what's involved in linking a 48 volt dc generator to ones 48 Volt drive system?   Is it as simple as connecting to the batteries?  If the generator senses a voltage draw then it engages, this is how most generators are set up .  Seems like there's got to be some sort of protection for the batteries so they don't see too much voltage.   I was thinking of having a 48 V dc generator in an inflatable secured to my deck and feeding my motors for surface transit.  Then once at the dive site leave the inflatable floating at the dive site.   Brian  _______________________________________________
