Sigenergy: intelligent storage and next-generation energy

Check power supply, models and serial numbers, cabling and communication ports, addressing, terminations, firmware and correct plant association. Creating the plant does not guarantee that every device is linked correctly.

If demand is low and export is limited, the system must reduce production when the battery can no longer absorb surplus energy. Check the effective export limit, meter, setpoints and simultaneous PV, load, grid and battery curves.

Check power supply, communications, grid status, safety inputs, configuration, firmware and Gateway events. An open contactor may be a protective response and must not be forced without identifying the condition preventing closure.

Define grid-forming operation, critical loads, power and peaks, autonomy, neutral and earthing arrangement, Gateway, protection and generator logic. Any architecture without a Gateway or with third-party equipment must be explicitly validated.

Verify meter or CT position, direction and phases, phase matching, communications and power sign. Then compare actual measurements with the platform. A nominal 5 kW setting may behave as zero export if measurement or the effective setpoint is incorrect.

Model and serial number, firmware, grid type, contracted power, diagram, connectivity, mySigen status, authorisation method and error messages. For dynamic load management, identify the meter, limits and other coordinated chargers or loads.
