Waeco SinePower MSI wireless display
Interfacing Waeco SinePower wirelessly
This little project describes, how you can easily access the remote port of a Waeco (dometic) SinePower inverter wirelessly.
I received the RS 232 protocoll description from dometic - like offered in the manual - and programmed around with the arduino development system and XBEE wireless connection.
The technology should be applicable to SinePower MSI 912, 924, 1312, 1324, 1812, 1824, 1812T and 1824T.
I had a 1812, like shown in the pictures.
Target of the project - transferring data wirelessly to a LCD
transferring battery voltage (input: 12 VDC or 24 VDC)
transferring output voltage of the inverter
transferring output currrent of the inverter
transferring output power of the inverter
transferring output frequency of the inverter
further development: showing data at a little self-refreshing web page
further development: transferring the state of a switch connected to the base station wirelessly to the remote inverter station to control a relay for braking a Silentwind 400+ wind generator
A 4 x 20 character LCD will be used.
