• With a timer and light sensor, it can be used in solar lighting systems.
• Only suitable for off-grid PHOTOVOLTAIC solar systems.
• For 10A 12V PV systems: 120W solar panels, 12V lead-acid batteries, 21V for maximum input voltage
• For 20A 24V PV systems: 240W solar panels, 24V lead-acid batteries, 42V for maximum input voltage

Safety instructions

• Before installing the battery for the first time, ensure that the battery has enough voltage to enable the controller to identify the battery type.
• Battery cables should be as short as possible to minimize loss.
• The regulator is only suitable for lead acid batteries: OPEN, AGM, GEL
• It does not work with nickel-metal hydride, lithium-ion, or other batteries.
• Charge regulators are only suitable for regulating solar modules. Do not connect other charging sources to the charging regulator.

System connection

• Connect the battery to the charging regulator – positive and negative. If a 12V battery is detected, it will display 1; If a 24V battery is seen,
• Connect the PV module to the regulator – positive and negative.
• Connect the user to the charging regulator – positive and negative.
• The reverse order applies when unloading
• The improper sequence will damage the controller!
