Commissioning/es

Ejemplo de lista de comprobación de puesta en marcha.

El proceso de puesta en marcha es el proceso de encender un sistema por primera vez de manera metódica para garantizar que esté construido como debe estar, que esté funcionando de forma segura y que funcione como debería. Todo el trabajo de instalación debe completarse antes de que comience el proceso de puesta en marcha; es el paso final. Un proceso de puesta en marcha requiere la inspección física del equipo, la programación del equipo y la prueba del rendimiento del equipo. El proceso variará para cada sistema, ya que cada sistema variará en términos de componentes o diseño, pero hay pasos que son comunes al proceso de puesta en marcha de cualquier sistema FV autónomo.

El proceso de puesta en marcha tiene como objetivo identificar cualquier error potencial de diseño o instalación antes de que los problemas representen un riesgo de seguridad para los instaladores, los usuarios finales o el equipo en sí. El proceso debe realizarse metódicamente con todos los pasos realizados independientemente de si la persona haciendo el proceso de puesta en marcha estuvo directamente involucrado en la instalación de un determinado componente o tarea. Nadie tiene la intención de cometer errores, sin embargo, ocurren. Marcar mentalmente las tareas durante el proceso de instalación no es lo mismo que realizar un proceso de puesta en marcha adecuado al final de una instalación que sigue una lista de comprobación.

If an issue arises during the commissioning process - an installation error is found, a component is not being having as it should be - the process should be stopped until the issue has been addressed. It may be necessary to troubleshoot the system to identify the issue. It is important to have the system plans and manuals for all of the equipment in order to diagnose and resolve issues.

Any component programming should be performed during the commissioning process. Special:MyLanguage/Charge controller programming and inverter programming are of particular importance. Following the installation manual that details setup and programming is very important as the settings vary between manufacturers and models. It will also be necessary to have the manual for the energy storage system on hand. Complex systems may have hundreds of different programmable parameters, but these are frequently left on default settings and only a few primary settings are changed. Programming plays a vital role in the functioning of a PV system and an improperly programmed PV system may function poorly or not at all - even if it was designed and installed perfectly.

The commissioning process should be performed in three different phases. All phases should be undertaken methodically with safety as the primary concern. Turning on and testing a system for the first time can present unknown hazards to the person performing the process.

Phase 1: Initial commissioning

1. Follow proper electrical safety. All work should be completed. Everyone in the area should be made aware that the commissioning process is going to begin, which means that the system is going to become energized.
3. Open (turn off) all overcurrent protection devices and disconnects to ensure that there is no connection between all power source and all other components in the system.
5. Ensure that all equipment - particularly the inverter - is turned off.
7. Perform a physical revision of the system as compared to the system design:

• Are all components the correct manufacturer and model? Are the power and voltage ratings correct?
• Is the system properly labeled?
• Are all system components connected to one another correctly?
• Is the grounding system built properly?
• Are all system connections made properly?

• Are all series and parallel connections performed correctly?
• Wiggle the wires for each connection to ensure that they are not loose.
• Are all wires the correct size?
• Are all wires protected and secured?

9. Battery

• Measure and record the voltage of each battery. Are all of the measurements similar? Is the voltage of each battery within an appropriate range for the battery type?
• Measure the voltage for each parallel string of batteries? Are the voltages correct for the design?
• Measure the voltage of the final connection between the battery bank and the charge controller. Is the voltage and polarity correct for the design?
• Measure the voltage of the final connection between the battery bank and the inverter. Is the voltage and polarity correct for the design?
• If voltages and polarities are correct, connect the battery bank to the rest of the system by closing the overcurrent protection devices and disconnects for the battery bank.

10. Charge controller

• Check voltage at the overcurrent protection device/disconnect for the charge controller. Is the voltage and polarity correct for the design?
• If voltage and polarity is correct, close (turn on) all overcurrent protection devices/disconnects between the battery bank and charge controller.
• Has the charge controller registered the voltage and turned on? If so, proceed with the process.

11. Inverter

• Check voltage at the overcurrent protection device/disconnect for the inverter. Is the voltage and polarity correct for the design?
• If voltage and polarity is correct, close (turn on) all overcurrent protection devices/disconnects between the battery bank and charge controller.
• Turn on the inverter.

• Is it operating correctly? No errors?
• Is the inverter outputting the correct voltage? If so, proceed with the process.

Phase 2: Programming

1. Charge controller programming
3. Inverter programming

Phase 3: Final commissioning

1. PV source

• Check the voltage and polarity for each parallel string of PV modules. The value will vary based upon the conditions but should be within an appropriate range given the conditions.
• If voltages and polarities are correct, close (turn on) all overcurrent protection devices/disconnects between the PV source and the charge controller.
• Has the charge controller registered the voltage from the PV source? If so, proceed with the process.

3. Power distribution

• Check the voltage and polarity of any DC lighting circuits or DC circuits connected to the battery. Is the voltage and polarity correct for the design?
• If the voltage and polarity are correct, close (turn on) all overcurrent protection devices/disconnects between the DC power source and the loads.
• Have the loads (lights and appliances) registered the voltage from the DC power source? If so, proceed with the process.
• Check the voltage of all AC circuits connected to the inverter. Is the voltage correct for the design?
• If the voltage is correct, close (turn on) all overcurrent protection devices/disconnects between the AC power source and the loads.
• Have the loads registered the voltage from the AC power source? If so, proceed with the process.

5. Documentation

• Make sure that the process has been documented as this information can be useful later on. Take photos of the system if possible.
• Make sure that anyone who will be using the system understands how to do so properly.
• Make sure that someone who will be using the system understands how to maintain and troubleshoot the system.
• Make sure that appropriate manuals and documentation remain with the system.
