PowMR 30A PWM Solar Panel Battery Charge Controller12V 24V


  • Built-in industrial microcontroller.
  • Large LCD screen, all parameters adjustable.
  • Full level 4 PWM charging management.
  • Built-in short circuit protection, open circuit protection, reverse connection protection, and overload protection.


  • Rated voltage: 12V 24V automatic
  • Application: Solar energy system controller
  • Current: 30A
  • 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!
