 The charger with work always with load, else it's not a charger so
you might consider the input of 60V.  0.9Ah does tell nothing about
the momentary current. So which is the maximum current you may get
from the pannel at 60V with full bright ?
This will be the load current of the charger. You have to limit the
charging current of the accumulator to source in the worst situation
the maximum current.
