- | Normally these solar chargers will reduce their output power as soon as the battery voltages hits the absorption voltage. When the goal is to feedback excess power to the grid, the solar charger should continue to operate on the Maximum Power Point instead. By using this interface together with the Hub-1 Assistant, that is exactly what will happen: the VE.Bus device will instruct the solar charger to continue maximizing solar output, and any excess power available on the DC side will be fed back by the VE.Bus device into the grid. | + | But, since the release of CCGX v1.73, it is no longer necessary. |

Note that this is the only purpose of this cable. In all other systems, where feedback of DC-coupled PV power to the grid is not intended, do not use this cable. | Note that this is the only purpose of this cable.

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. | To install the cable, simply connect it between the VE.Bus device and the solar charger(s).
