Make sure to open all mechanical disconnects and test all connections with electrical meter before servicing equipment. Grid Tie Support local loads and export solar power to the utility grid. Batteries are inactive in Grid Tie mode. Self Supply Utilize both solar power and battery power to support local loads before exporting surplus solar to utility grid. Battery power will not be exported to the utility grid in Self Supply. Current transformers (CTs) are required for Self Supply Clean Backup Charge batteries from solar only before supporting local loads and exporting to utility grid. Priority Backup Charge batteries with both solar and the utility grid Priority Backup will charge the batteries as fast as possible. Sell Export full capacity, including battery power, to utility grid. Sell mode will cause batteries to discharge to the utility grid External CT Power measurement Positive is exporting, negative is importing. Reads 0x8000 when CTs are not connected.
