Instruction manual for Manual for BlueSolar PWM Charge Controller – LCD - USB shows on page 2 the warning:
BlueSolar Charge Controller is only suitable for regulating solar modules.
Never connect another charging source to the charge BlueSolar Charge
while the user manual Manual BlueSolar PWM-Light 48V Charge Controller does not contain this warning.
What happens if we connect a 80V battery instead of solar panels to the input ? Possibly the reverse polarity protection will blow in case of accidental wrong connection but shouldnt it start charging any battery with voltages 24/48V ?
