Solar Panels / Charge Controllers
SMART PWM TECHNOLOGY: The controller is compatible with 12V and 24V systems, with a discharge current of 30A. It features dual USB outputs at 5V/2.5A and an integrated industrial microcontroller for automatic management. The microcontroller remembers user-set parameters and ensures data retention even when the battery is discharged. The controller supports lead-acid, ternary lithium, and lithium iron phosphate batteries. Modes include b1 for lead-acid, b2 for ternary lithium, and b3 for lithium iron phosphate.
FUNCTIONAL LCD SCREEN: Installation and operation are easy, thanks to the intuitive LCD display. This screen clearly indicates battery status and allows you to switch modes and configure parameters. You can adjust the level of complete power-off to perfectly protect lithium batteries from over-discharge. Perfect for use in homes, industries, and commercial settings.
3-STAGE PWM CONTROL CHARGING: Our product uses a fully 3-stage PWM regulation charging system, including direct charge, lifting charge, and floating charge modes. An efficient and fast intelligent charging method is employed to prolong battery service life effectively.
MULTIPLE INTELLIGENT PROTECTION: Built-in overcurrent, short circuit, reverse connection, and open circuit protections ensure automatic recovery without harming the controller. This makes it a reliable protector for your devices. If the battery voltage drops below 8V, the solar controller will automatically shut down to protect the battery life.
