The appropriate amount of amps would keep the battery
0.4v is quite a large change, the current charging
will vary considerably with this voltage difference.
If 13.4v is an appropriate voltage at a particular SOC the regulator should maintain this voltage, irrespective of the load (if the solar
output is sufficient).
