New static inverter

To replace my old and small generator, I bought a static inverter able to output pure sine wave 115VAC 400Hz 3 Ph with a rating of 3000VA and an efficiency of 80%; the Input is 28VDC up to 140A.
It should be enough to power all cockpit gauges and computers.
The unit features 3 inverter units which are controlled to have a phase shift of 120° and has an active cooling system provided by internal fan.

Here you can see a video during unit startup and shutdown.
