1. Introducción
This manual provides essential instructions for the safe and efficient operation of your Phocos CIS10 IP68 10Amp Solar Charge Controller. The CIS10 is designed for off-grid solar light systems and battery charging, featuring automatic 12V/24VDC system voltage detection and a robust IP68 waterproof design. Please read this manual thoroughly before installation and use.
2. Información de seguridad
Instrucciones de seguridad importantes:
- Conecte siempre primero la batería al controlador de carga, luego al panel solar y, por último, a la carga. Desconecte en orden inverso.
- Ensure all connections are tight and secure to prevent excessive voltage drop and loose connections.
- Install the controller in a well-ventilated area, away from flammable gases.
- No desmonte ni intente reparar el controlador usted mismo. Contacte con personal cualificado para obtener servicio técnico.
- Wear appropriate personal protective equipment (PPE) when working with batteries and solar panels.
- The controller is IP68 rated for water and dust ingress, but avoid submerging it for extended periods or exposing it to high-pressure water jets.
3. Características del producto
The Phocos CIS10 Solar Charge Controller offers the following key features:
- Diseño impermeable IP68: Suitable for outdoor use, resistant to water spray, rain, and condensation.
- Vol automáticotagy Detección: Detecta automáticamente vol del sistema 12V o 24V DCtages.
- 5-StagTecnología PWM: Provides Soft Start, Bulk, Absorption, Float, and Equalization charging stages for optimal battery health and system performance.
- Amplia compatibilidad de baterías: Works with LifePo4, LTO, GEL, AGM, Lead-Acid, Calcium, and EFB batteries.
- Funciones de protección múltiple: Built-in protection against over-temperature, over-voltage, over-current, over-charging, over-discharging, overload, and short circuits.
- Compact and Thin Design: Maximizes solar power utilization with minimal self-power consumption.
4. Configuración e instalación
Follow these steps for proper installation of your Phocos CIS10 controller:
- Montaje: Choose a suitable location for mounting the controller. Although IP68 rated, mounting in a shaded or protected area can extend its lifespan. Ensure adequate space for cable connections.
- Conexión de la batería: Connect the battery cables to the controller's battery terminals first. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the system voltage (12 V o 24 V).

- Conexión del panel solar: Connect the solar panel cables to the controller's solar panel terminals. Observe correct polarity. The controller will begin charging the battery.
- Conexión de carga (opcional): If using the controller for a DC load (e.g., solar light), connect the load cables to the controller's load terminals. Ensure correct polarity.
- Verificar conexiones: Double-check all connections for tightness and correct polarity before powering on the system.
The controller's compact design and integrated wiring simplify installation. Its IP68 rating ensures durability in various outdoor conditions.

5. Instrucciones de funcionamiento
The Phocos CIS10 operates automatically once connected. It utilizes advanced 5-stage Pulse Width Modulation (PWM) charging technology to optimize battery charging and extend battery life.
5.1. Carga Stages
- Inicio suave: Gradually increases current to the battery.
- Carga a granel: Delivers maximum current to rapidly charge the battery to approximately 80% capacity.
- Carga de absorción: Carga la batería a un volumen constante.tage to bring it to 100% capacity.
- Carga flotante: Mantiene la batería con carga completa proporcionando un volumen pequeño y constante.tage.
- Igualdad: Automatically performs equalization every 28 days for calcium/EFB batteries to prevent sulfation and ensure cell balance.
5.2. Work Mode (Optional)
The CIS10 controller supports configurable work modes, such as time control and light control, which can be set using an optional external unit like the CIS-CU (sold separately). This allows for customized operation of connected loads, such as solar lights.
6. Mantenimiento
The Phocos CIS10 is designed for minimal maintenance due to its robust IP68 rating and epoxy-encapsulated PCB. However, periodic checks are recommended:
- Inspección visual: Inspeccione periódicamente el controlador y todas las conexiones para detectar signos de daño, corrosión o cableado suelto.
- Limpieza: If necessary, gently clean the exterior of the controller with a damp paño. No utilice productos químicos agresivos ni materiales abrasivos.
- Estado de la batería: Monitor your battery's performance. The controller's equalization feature helps maintain battery health for compatible types.
7. Solución de problemas
The CIS10 controller includes multiple built-in protections to prevent damage. If you encounter issues, consider the following:
- No Charging/Load Output:
- Verifique que todas las conexiones del cableado estén bien ajustadas y la polaridad sea correcta.
- Asegúrese de que el panel solar reciba la luz solar adecuada.
- Verifique el volumen de la bateríatage está dentro del rango operativo (12 V/24 V).
- Check for any blown fuses in the system (if applicable).
- Protección contra sobretemperatura: If the controller becomes excessively hot, it may temporarily reduce or stop charging/output. Ensure it's not installed in an area with poor ventilation or direct, intense heat.
- exceso de volumentage/Sub-Voltagy Protección: The controller will protect the battery from overcharging or deep discharge. If the battery voltage is too low, the load may be disconnected.
- Short Circuit/Overload Protection: If a short circuit or overload occurs on the load or solar input, the controller will temporarily shut down to protect itself and the system. Remove the fault and the controller should resume normal operation.
If problems persist, refer to the detailed specifications or contact Phocos customer support.
