inverter with peak efficiency of 97% !!
With this inverter, Kostal and your engineers have developed the world's best device with a top efficiency of a sensational 97%. In addition, the input voltage range is very large at 75 to 750 volts. The efficiency is kept extremely high not only at a certain voltage or power but almost over the entire voltage range.
Of course, the inverter is a bit more expensive than comparable devices, due to the higher output that is fed in every day, but these costs are recovered. Since the device generates almost no power loss, there is also no cooler and the housing can be hermetically sealed. Due to the low temperatures inside the device, the service life could be increased further. A corresponding DC isolator is built in and allows the system to be disconnected from the power supply at any time. A display is integrated on the front where the yield and the electrical characteristics can be read.
The inverter has one or 2 MPP trackers, one of which can always be used as a bidirectional input / output and thus a high-voltage battery, e.g. from BYD, can be connected.
Monitoring can be carried out via the free Kostal portal.
