Quick Answer
When troubleshooting uneven output in a parallel connection, check the voltage difference between the two sources, and ensure the generator parallel kit is functioning correctly, possibly by adjusting the load or re-setting the kit. A 5-10% voltage difference is acceptable, but higher differences may indicate a problem. Consult the kit's manual for specific troubleshooting steps.
Inspecting the Parallel Kit
Inspect the generator parallel kit for signs of wear or damage, such as frayed wires or loose connections. Verify that the kit’s automatic voltage regulator (AVR) is functioning correctly, as it helps maintain a stable output voltage. Check the kit’s documentation for specific settings and recommendations for your particular generators.
Analyzing the Voltage Difference
Use a multimeter to measure the voltage difference between the two sources. For most generator parallel kits, a voltage difference of 5-10% is acceptable. If the difference is higher, it may indicate a problem with the kit, one of the generators, or the load. Divide the load equally between the two generators to minimize the voltage difference.
Adjusting the Load and Kit Settings
Adjust the load on each generator to ensure they’re drawing equal power. Consult the generator’s manual for specific settings and recommendations. For the parallel kit, adjust the AVR settings according to the kit’s documentation. Re-set the kit and re-measure the voltage difference to ensure it’s within the acceptable range.
