I agree the vehicle's battery is not going to be done any favours with the charge currents the alternators can punch out, but the alternators are sized for the high current draws of the kit the vehicle has, ie seat heating, lighting etc.
Even a 400 Watt output inverter is going to take over 33 Amp before its losses are considered. This load ought to be available from the reserves the alternator gives above the demands of the vehicle's battery.
The wiring alternator to the inverter will need to be very carefully considered, even for such a modest one as 400Watts.
As said earlier, it was a onetime dream, but the challenges simply made chasing it too much for me.
I have a bike battery that actually has achieved over 100 miles, on the terrain I take on these days, and my age now leads to about 20 mile rides.
A battery of that capability gives 4 days riding before becoming critical. The consequences are recharging during a camping break are not what I originally assumed I would face. Therefore, that and grabbing a opportunity to boost a bit over lunch, serves my needs without developing an on board recharge facility.
If I knew more about charging my bike battery I would explore making a bespoke DC to DC converter to clamp on the vehicle's alternator. Back in 2015 when doing my bike purchase investigations, Bosch did a DC input charger, but at an eye watering price [£140 ?? if I recall]. I doubt if I would have paid it, but in the end did not go Bosch anyway.
It would be interesting to know of others here who have cracked in "car" recharging of bike batteries, in a worth the effort way?
