We have installed a few solar panels, a battery and a SunSynk 12K 3-phase Hybrid Inverter at work. It runs fine in "island mode", meaning that the solar panels and battery are working fine alone or together, but it never uses the grid. There are no fault codes, the inverter just never uses any power from the grid. The grid power is always at 0W.

Solar panel fault-finding guide including examples and how to inspect and troubleshoot poorly performing solar systems. Common issues include solar cells shaded by dirt, leaves or mould. Check all isolators are all on, and the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues.
If they have never produced, it is very likely to be an issue with the original installation. Either they have not been detected/provisioned (link to How to detect microinverters page) or there is a wiring issue. You can also see if they have produced before under "Lifetime energy" on the "Devices" tab: One microinverter not reporting

At night or during cloudy weather, when your solar panels are not producing enough power to meet your household demand, you''ll pull electricity from the grid as you normally would. An on-grid solar inverter must be able to shut down automatically when the utility grid goes down, as feeding electricity into a downed grid can be dangerous.
Several factors, including the loosening or aging of power cords, incorrect orientation of PV input terminals, or failure to properly engage DC switches, can significantly hinder the operational capabilities of the inverter.
Given the significance of this issue, the present paper starts with a review of different failure modes occurring in various components of grid-connected photovoltaic systems, before offering a deeper review of the state of the art of fault diagnosis techniques specifically applied to solar photovoltaic systems in microgrids.
This study proposes an optimal framework (efficient and cost saving) in the upkeep of solar PV microgrids throughout the design lifespan as well as delivering repair and replacement needs.
Electricity produced by the microgrid is distributed to end users, such as households, businesses, and other facilities, to meet their energy needs. It can power various devices, machinery, and appliances. Many solar microgrids have the capability to connect or disconnect from a larger grid as needed.
Both the source and load are maintained at a constant value of 25 kW and 20 kW, respectively. Fig. 10 shows that the power generated from the solar and wind are indicated as 5 kW and 20 kW respectively. The load of the microgrid system is 27 kW, and it is understood that the battery’s negative power indicates that the battery is in charging mode.

Smart Grid Integration: Integration with smart grid technologies will optimize the performance of solar microgrids by enabling real-time monitoring, predictive maintenance, and dynamic load management. This intelligent coordination ensures efficient energy usage and maximizes cost savings for consumers.
Grid Independence: Unlike utility-scale solar, microgrids can operate independently of the main power grid. This independence offers resilience and reliability, especially in remote areas or during grid outages.
Cost-Efficient Operations: Solar microgrids empower businesses to reduce energy costs significantly. By harnessing solar energy, companies can offset reliance on traditional grid electricity, thus cutting down operational expenses. Reliable Power Supply: Ensuring uninterrupted power is crucial for businesses.
