Description
The Chint monophastic vatimeter, model DDSU666, is a devices that serves to measure energy at the main entrance to the house, with the aim of knowing the electricity consumption that can provide photovoltaic installation. Thus, the vatimeter communicates with the inverter Solax or SAJ, of connection to the network, so that it can be adequately adapted to the energy of output to reading at all times.
With the measure of electrical instant consumption and communication by RS485 interface, the logic of inverter It can limit the power output to the maximum of the real consumption of the home of that moment.
It is an element that allows us, in the event that we love it, do not pour surplus solar electric production to the network to which we are connected. It is also useful for measuring the need for electricity we have, with what, added to the fact that the inverter Know the amount of power we produce, we can have a comparison between generated energy and energy required.
The inverters compatible with this device are the Solax X1-Hybrid and X1-Boost, and the SAJ of the R5 series. All of them need this device to be able to perform the zero pouring function.
