IgnoreZeroConverter (OpenEMS Javadoc)

java.lang.Object
- io.openems.edge.bridge.modbus.api.ElementToChannelConverter
- - io.openems.edge.battery.fenecon.commercial.IgnoreZeroConverter

```
public class IgnoreZeroConverter
extends ElementToChannelConverter
```
Before the battery is started, values are wrongly received as 'zero' via Modbus. This logic replaces these wrong values in the beginning with 'null'.
The class optionally creates a ElementToChannelConverterChain, for use-cases when additionally to the above 'zero/null' logic a scale-factor is required.
