Here's the situation : I have an electric vehicle with 72v batteries inside. What would happen if I disconnect my solar panels from the 250 / 60 smartsolar and plug the 72v instead ?! I guess it's gonna work like a dc dc step down charger with my 56.8v lifepo4 battery !!!???!!!
And what would happen if this 72vdc battery is plugged IN PARRALLEL with 220vdc solar panels (6 trina vertex 400 in series) to the smartsolar's PV input ?
Even weirder : the fact is that my 72vdc vehicle can be directly charged by a 54vdc voltage. So how fried am I if I have PV + 72v battery on the smartsolar pv input... + my EV controller (not directly the 72v battery, this controller charges through the motor used as an induction) on the smartsolar's 48v battery output ?!?!?!?
Of course I see some diodes, fuses etc potentially added but let's discuss the questions above first, please.
I imagine a situation in winter when I don't move from home and would be happy to reduce daily manipulations on the system. The other huge advantage would be that my vehicle can be used to charge 10kWh outside of my offgrid facility and come back to feed my system in case of super bad weather. Big battery on wheels !
