• Parameter
• Input Voltage: DC 18-90V
• Output Voltage: DC 2-60V
• Output Current: 0-25A adjustable
• Unattended automatic lithium battery charging without activation
• Charges even on cloudy days; automatically stops when fully charged
• Automatic temperature-controlled fan cooling
• Can function as a step-down regulated adjustable power supply
• Commissioning Procedure
• Connect 16V-80V PV panel input (do not exceed input voltage; observe polarity). Correct wiring activates the power indicator light. If the output indicator light illuminates immediately, proceed directly to Step 3.
• If the power indicator lights up after input connection but no output voltage is present, first adjust the MPPT potentiometer counterclockwise until voltage output appears and the output indicator lights up.
• For charging a 12V battery, set output to 14.2V; for a 24V battery, set output to 28.4V; for a 48V battery, set output to 56V.
• Set the output voltage to 14.2V and output current to 20A. Adjustable range: 1-20A. Set the MPPT voltage to 17V.
