Re: House systems - separate or together with drive system?
Ryan, How much house power do you need, and what is the relative balance of motor power vs. house power? If the house requirements are tiny, then running a converter to regulate the 48V down to 12V

Re: Need some mechanical help in UK or Oz to prepare for electric - anyone recommended?
Hi Reuben, Thank you! That helps a lot. I was trying to get away from machining a keyway by bolting onto the coupling - the keyway would be much more costly and time consuming. I totally agree with

Re: AC vs DC gensets, how many?
There¡¯s no free lunch. If the motor is generating 5kW then you¡¯ll be using 5kW if diesel plus at Keats 10% for losses. that said, it¡¯s more efficient than adding a stand alone generator making

A 1¡± clogged belt is OK for 10 kW. That¡¯s what I have. Perhaps you¡¯ll need the shaft pulley aft of the coupling - you¡¯ll need to pull the shafts and have them machined for the pulley key way.
