The VE.Direct to VE.CAN interface cable can be used to make BMV-700 information available on a VE.Can network. To install the cable, simply connect it between the VE.Bus device and the solar charger(s). Separately powering the VE.Can network is not necessary, since it is powered by the solar charger(s). Same for the VE.Bus network, it will be powered by the VE.Bus device.
