Please read this manual thoroughly before installation and use.
2. Informació de seguretat
Instruccions importants de seguretat:
- Connecteu sempre primer la bateria al controlador de càrrega, després al panell solar i finalment a la càrrega. Desconnecteu-ho en ordre invers.
- 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.
- Do not disassemble or attempt to repair the controller yourself. Contact qualified personnel for service.
- 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. Característiques del producte
The Phocos CIS10 Solar Charge Controller offers the following key features:
- Disseny impermeable IP68: Suitable for outdoor use, resistant to water spray, rain, and condensation.
- Volum automàtictage Detecció: Detecta automàticament el volum del sistema de 12 V o 24 V CCtages.
- 5-Stage PWM Technology: Provides Soft Start, Bulk, Absorption, Float, and Equalization charging stages for optimal battery health and system performance.
- Àmplia compatibilitat de bateries: Works with LifePo4, LTO, GEL, AGM, Lead-Acid, Calcium, and EFB batteries.
- Funcions de protecció 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. Configuració i instal·lació
Follow these steps for proper installation of your Phocos CIS10 controller:
- Muntatge: 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.
- Connexió de la bateria: 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 (12V o 24V).

- Connexió del panell solar: Connect the solar panel cables to the controller's solar panel terminals. Observe correct polarity. The controller will begin charging the battery.
- Connexió de càrrega (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.
- Verifica les connexions: 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. Instruccions de funcionament
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. Carregant Stages
- Inici suau: Gradually increases current to the battery.
- Càrrega massiva: Delivers maximum current to rapidly charge the battery to approximately 80% capacity.
- Càrrega d'absorció: Carrega la bateria a un volum constanttage to bring it to 100% capacity.
- Càrrega del flotador: Manté la bateria a plena càrrega proporcionant un petit volum constanttage.
- Igualació: 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. Manteniment
The Phocos CIS10 is designed for minimal maintenance due to its robust IP68 rating and epoxy-encapsulated PCB. However, periodic checks are recommended:
- Inspecció visual: Periodically inspect the controller and all connections for any signs of damage, corrosion, or loose wiring.
- Neteja: If necessary, gently clean the exterior of the controller with a damp tela. No utilitzeu productes químics o materials abrasius.
- Salut de la bateria: Monitor your battery's performance. The controller's equalization feature helps maintain battery health for compatible types.
7. Solució De Problemes
The CIS10 controller includes multiple built-in protections to prevent damage. If you encounter issues, consider the following:
- No Charging/Load Output:
- Comproveu totes les connexions del cablejat per assegurar-vos que estiguin ben ajustades i que la polaritat sigui correcta.
- Assegureu-vos que el panell solar rebi la llum solar adequada.
- Comproveu el volum de la bateriatage està dins del rang de funcionament (12V/24V).
- Check for any blown fuses in the system (if applicable).
- Protecció 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.
- Més de voltage/Under-Voltage Protecció: 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.
