Ensuring the correct installation of your hoymiles HT10 Rapid Shutdown Transmitter is crucial for optimal performance. Here's how to verify a successful setup:
- Power LED1 Status: When the PV system is active, the Power LED1 on the Transmitter should be illuminated, indicating the unit is receiving power.
- Signal LED2 Activity: The Signal LED2 on the Transmitter should be blinking during PV system operation. This signifies the Transmitter is successfully transmitting signals.
- Rapid Shutdown System Label Placement: Confirm the rapid shutdown system label is positioned within 1 meter (3 feet) of the Transmitter or AC disconnect if they are not in the same location. This aids in quickly identifying rapid shutdown components.
- Strings per Core Compliance: Verify that the number of strings connected to each Core doesn't exceed the specified limits (5 for a 75A core or 15 for a 150A core).
- Current per Core Limits: Ensure the current flowing through each Core remains within the maximum allowable values (75A or 150A).
- Cable Length Consideration: Check that the cable length from the inverter's positive terminal to the negative terminal doesn't exceed 1000 feet (300 meters), using a Φ 6 mm DC cable diameter.
By carefully checking these indicators and referring to the installation instructions in the hoymiles HT10 Rapid Shutdown Transmitter manual, you can confidently confirm a correct and safe installation, setting the stage for reliable operation of your solar system.
