What is the Sunbird 3000?

Sunbird 3000 is Fuji Electric's three-phase, bi-directional solar hybrid inverter (Hybrid PCU) ranging from 10 KW to 400 KW. It combines solar MPPT charging, grid interaction, and battery backup functionality in one modular unit.

Can Sunbird 3000 operate without a battery?

Yes. It's a true bi-directional solar inverter with battery-independent operation, meaning it can function as a standard solar inverter even when no battery is connected to the system.

What battery types does it support?

SMF, VRLA, Wet Lead Acid, TGel, and Li-ion batteries are all supported, at battery voltages of 120V, 240V (with a 360V/480VDC option at 100KW), 540V, or 600V depending on the system rating.

How does the MPPT charging work?

MPPT (Maximum Power Point Tracking) is achieved through incremental conductance algorithms, using an IGBT-based charge controller with PWM switching built on Space Vector technology , the same switching approach used on the output/inverter side.

Can the Sunbird 3000 charge batteries directly from the grid?

Yes. Battery charging through the grid is supported up to 100%, and a selectable priority feature lets the system be configured to prioritize either grid or battery as the source.

What makes the modular construction useful?

The modular internal design is built specifically to reduce MTTR (mean time to repair) , a fault in one module can typically be addressed by servicing or swapping that module rather than requiring extended downtime for the whole unit.

Does Sunbird 3000 help with power quality issues on the grid side, not just solar?

Yes. It provides PF correction while operating on mains supply (line-interactive) and active harmonic filtering with load correction at 100% load, keeping THDi under 5% and power factor above 0.9.

What protections are built in?

Under/over-voltage protection across input, output, array, and battery; array and battery reverse-polarity protection; output overload and short-circuit protection; over-temperature protection; MCCB protection on input, output, array, and battery paths; surge protection for grid and array; and an inbuilt isolation transformer at the inverter output.

What standards does Sunbird 3000 comply with?

Efficiency testing per IEC 61683, environmental testing per IEC 60068, inverter testing per IEC 62040 part III, active filter function compliance with IEEE 519, and islanding protection per IEC 62116.
