Let&#8217;s troubleshoot step by step:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. <strong>Verify Wiring<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Battery Connections<\/strong>: Ensure the batteries are connected securely and polarity is correct.<\/li>\n\n\n\n<li><strong>Utility Input<\/strong>: Check that the AC input from the grid (utility) is properly connected to the inverter.<\/li>\n\n\n\n<li><strong>Bypass and Load Connections<\/strong>: Verify that the load and bypass lines are connected correctly per the manual.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Setting #16: Charger Source Priority<\/strong><\/h3>\n\n\n\n<p>This setting determines the source used to charge the batteries. The options are typically:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Solar first<\/strong>: Solar panels are prioritized for charging.<\/li>\n\n\n\n<li><strong>Utility first<\/strong>: The grid is prioritized for charging.<\/li>\n\n\n\n<li><strong>Solar and utility<\/strong>: Both can charge the batteries as needed.<\/li>\n\n\n\n<li><strong>None<\/strong>: Charging is disabled.<\/li>\n\n\n\n<li>Make sure setting #16 is configured to <strong>Utility first<\/strong> or <strong>Solar and utility<\/strong> if you want grid power to charge the batteries.<\/li>\n\n\n\n<li>Save the setting and restart the inverter if required.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>Check the Charging Current (Setting #11)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Verify that the <strong>maximum charging current<\/strong> is set appropriately for your battery bank.<\/li>\n\n\n\n<li>If it\u2019s set too low, the inverter might not detect enough capacity to start charging.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. <strong>Battery Type Configuration (Setting #5)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ensure the inverter is configured for the correct <strong>battery type<\/strong> (e.g., lithium, AGM, gel).<\/li>\n\n\n\n<li>Incorrect settings can cause the inverter to misinterpret charging parameters.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5. <strong>AC Input Voltage Range (Setting #3)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ensure that the input voltage range matches your utility supply.<\/li>\n\n\n\n<li>If the range is incorrect, the inverter might not recognize the grid input for charging.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6. <strong>Error Codes or Alarms<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Check for any error messages or alarms on the inverter display.<\/li>\n\n\n\n<li>Certain alarms (e.g., overvoltage or undervoltage) might prevent charging.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">7. <strong>Firmware Update<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Some issues might be firmware-related. Check if your inverter has a firmware update available, and update it if necessary.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">8. <strong>Test the Utility Charging Functionality<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Temporarily disconnect the solar input to see if the grid charges the batteries alone.<\/li>\n\n\n\n<li>This can help isolate the issue.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">9. <strong>Contact Technical Support<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If all settings are correct and the problem persists, it could be a hardware issue. Contact EG4&#8217;s technical support for guidance.
