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.
Principais características
- 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.
- Totalmente 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.
Instruções de segurança
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.

Configuração e instalação
Follow these steps for proper installation of the solar charge controller. Ensure all connections are secure and correct to prevent damage.
- Conecte a bateria: First, connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage (12V ou 24V).
- Conecte os painéis solares: Next, connect the solar panels (PV array) to the charge controller. Again, observe correct polarity.
- Conecte a carga CC: Finally, connect your DC load (e.g., lights) to the charge controller.
Important Wiring Sequence:
Battery → Solar Panels → DC Load

Operação
Interface do display LCD
The LCD provides real-time information about your solar system. The interface includes icons and numerical values for easy monitoring.
Figura 3: Detalhado view of the LCD display, explaining each icon and its corresponding meaning for system status monitoring.
Carregar modos de trabalho
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.

Manutenção
The Anern PSC 20A Solar Charge Controller is designed for low maintenance. However, regular checks can ensure optimal performance and longevity:
- Inspecione periodicamente todas as conexões da fiação para garantir que estejam firmes e livres de corrosão.
- Mantenha o controlador limpo e livre de poeira e detritos. Use um pano seco para a limpeza.
- Garanta ventilação adequada ao redor do controlador para evitar superaquecimento.
- Monitor the LCD display regularly for any error codes or unusual readings.
Solução de problemas
Esta seção aborda problemas comuns que você pode encontrar com seu controlador de carga solar.
Perguntas e respostas comuns
- P: Por que a tela LCD fica em branco?
- 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 retorna para 12.6V.
