Tips: Precautions Before Commissioning of 5.5kW Hybrid Solar Inverter Commissioning.

Step one: Check the following requirements before commissioning 5.5kW hybrid solar inverter:

  1. Ensure the 5.5kW hybrid solar inverter is firmly secured.
  2. Check if the open circuit DC voltage of PV module meets requirement.
  3. Check if the open circuit utility voltage of the utility is at approximately same to the nominal expected value from local utility company.
  4. Check if connection of AC cable to grid (utility) is correct if the utility is required.
  5. Full connection to PV modules.
  6. AC circuit breaker (only applied when the utility is required), batter circuit breaker, and DC circuit breaker are installed correctly.

Step two: Switch on the battery circuit breaker and then switch on PV DC breaker. After that, if there is utility connection, please switch on the AC circuit breaker. At this moment, the hybrid solar inverter is turned on already. However, there is no output generation for loads. Then:

  1. If LCD lights up to display the current inverter status, commissioning has been successfully. After pressing "ON" button for 1 second when the utility is detected, this inverter will start to supply power to the loads. If no utility exists, simply press "ON" button for 3 seconds. Then, this inverter will start to supply power to the loads.
  2. If a warning/fault indicator appears in LCD, an error has occurred to this inverter. Please inform your installer.

Step three: Please insert CD into your computer and install monitoring software in your PC. Follow below steps to install software.

  1. Follow the on-screen instructions to install the software.
  2. When your computer restarts, the monitoring software will appear as shortcut icon located in the system tray, near the clock.

NOTE: If using modbus card as communication interface, please install bundled software. Check local dealer for the details.
