Anyone who has invested in a grid-connected solar power system on their property would of course want to know just how much solar power they are producing, and how much that is going to reduce their power bills. This grid-connect solar power monitor measures the power consumption of your home, the power being produced by your solar array, and also gives you a balance of the power you are consuming versus what your solar array is producing. It also displays the costs, with 3 tariffs for the electricity pulled from the grid, and a feed-in tariff for your solar production. Of course you also get a net cost that deducts the solar feed-in tariff amount from the electricity you pulled from the grid. Two wireless transmitters sit inside your meter box with attached sensors (one for your home circuits, and one for your solar inverter output) that wirelessly transmit the power information to the indoor display unit. The indoor display shows up all the relevant information on the large LCD display, with programming and options controlled by the front panel buttons. For those who want to get a little deeper into their solar power production and household consumption habits, you can connect the indoor display unit to your PC or laptop, and download the historical data (software available on the Watts Clever website). The wireless transmitters are powered by 2xC batteries each, whilst indoor display is powered by the included 240V AC adaptor with 3xAAA batteries for backup power.
NOTE: Only works with NET-METER grid-connect solar systems.
