Figura 0: Davant view of the Anern PSC 20A Solar Charge Controller, highlighting its LCD screen and control buttons.
The Anern PSC 20A Solar Charge Controller is designed to manage the power flow from your solar panels to your battery bank, ensuring efficient charging and protecting your battery from overcharge and over-discharge. This intelligent controller automatically detects 12V/24V system voltages and features a clear LCD display for monitoring system status and adjusting parameters. It includes dual USB ports for charging external devices.
Característiques clau
- Automatic management of solar panel and battery operation.
- Built-in industrial micro-controller for stable performance.
- Large LCD display for real-time data and adjustable parameters.
- Totalment 3 stage PWM charge management (Bulk, ABS, Float).
- Multiple protection functions: short-circuit, open-circuit, reverse polarity, over-load, low voltage, and overcharge protection.
- Dual 5V/2A USB ports for device charging.
Instruccions de seguretat
Please read and understand these safety instructions before installation and operation to prevent damage to the controller, battery, or other components.
- This controller is only suitable for lead-acid batteries: OPEN, AGM, and GEL types. It is not compatible with nickel-metal hydride, lithium-ion, or other battery types.
- The charge controller is designed exclusively for regulating solar modules. Do not connect any other charging sources to the charge regulator.
- The LCD display may have a voltage error of 0.2V - 0.3V, which is considered normal.
- Ensure battery cables are as short as possible to minimize power loss and maximize efficiency.

Configuració i instal·lació
Follow these steps for proper installation of the solar charge controller. Ensure all connections are secure and correct to prevent damage.
- Connecteu la bateria: First, connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage (12V o 24V).
- Connecteu els panells solars: Next, connect the solar panels (PV array) to the charge controller. Again, observe correct polarity.
- Connect the DC Load: Finally, connect your DC load (e.g., lights) to the charge controller.
Important Wiring Sequence:
Battery → Solar Panels → DC Load

Carregar els modes de treball
The controller offers three distinct load working modes, which can be configured via the LCD interface:
- 24H (24-hour operation): The load operates continuously for 24 hours.
- 0H (Light control mode): The load works only after dark.
- 1H-23H (Light and time control modes): The load works after dark for a set duration, configurable from 1 to 23 hours.

Manteniment
The Anern PSC 20A Solar Charge Controller is designed for low maintenance. However, regular checks can ensure optimal performance and longevity:
- Inspeccioneu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben ajustades i sense corrosió.
- Mantingueu el controlador net i lliure de pols i brutícia. Feu servir un drap sec per netejar-lo.
- Assegureu-vos que hi hagi una ventilació adequada al voltant del controlador per evitar el sobreescalfament.
- Monitor the LCD display regularly for any error codes or unusual readings.
Resolució de problemes
This section addresses common issues you might encounter with your solar charge controller.
Preguntes i respostes habituals
- Q: Why does the LCD screen become blank?
- A: The solar controller will stop outputting when the battery voltage drops below approximately 8V. In this state, the LCD screen will go blank. When the solar panels begin charging the battery again, the controller will resume output once the battery voltage torna a 12.6 V.
