The TD-203 has been designed to ensure maximum resilience. It offers a robust 20 kW platform that is able to manage a variety of power sources seamlessly. The TD-203's key feature is its versatile AC input acceptance, which allows it to draw power from both the utility grid and external generators. This dual-input functionality is crucial for areas with unstable grid infrastructure or for off-grid setups that rely on fossil fuel backups during prolonged cloudy weather. The inverter intelligently prioritises power sources, automatically switching to generator power when battery reserves are low, and reverting to solar or battery storage when fuel is scarce or the grid returns.

This seamless transfer capability ensures that critical loads never experience a dropout during source switching. The internal logic is programmed to protect the generator from overload while maximising the charging current to the battery bank, up to the unit's 20A limit. This makes it an excellent partner for diesel or gasoline generators, preventing them from running inefficiently under light loads. In addition, the system is designed to support a broad AC input voltage range, effectively dealing with the voltage fluctuations that are often experienced in weak grids without causing any unnecessary tripping. This tolerance ensures continuous operation even when the incoming power quality is poor. The inverter's centralised role in managing all available energy sources ensures the optimal utilisation of existing infrastructure. It provides a reliable power source, ensuring uninterrupted availability regardless of external conditions, making it a vital component of a robust energy infrastructure for farms, remote industrial sites, and large residential estates requiring uninterrupted energy.
