After installation Local Power will remotely monitor your Solar PV system and proactively respond to any issues should they occur.
Fronius inverters have comprehensive monitoring features as standard and with a smart meter can monitor consumption as well as solar generation through their web portal which can be accessed via computer, smartphone and tablet.
Local Power quotes their residential systems with consumption monitoring included. This is an invaluable feature which can allow customers to have feedback about their electricity use and whether they are being powered by the solar array or from the grid. Monitoring consumption and having comprehensive usage and generation data will help with sizing and designing future battery storage options.
In the graph below the solar generation “bell curve” on a sunny day can be clearly seen. As you can see in the graph, solar generation is the outline of the green curve, grey is the usage which has been offset with solar, and green is surplus electricity exported to the grid. The unshaded area below the black line is electricity imported from the grid at non solar generating times and when there is not enough solar generation.
There is also realtime feedback on smartphones and tablets such as the screens below showing an animation of the energy flows.
On the left screen the system is generating 2012W while the consumption is 2369W meaning the site is 85% self-sufficient by using 100% of their generation and is using an additional 357W from the grid.
On the right screen later in the day generation has dropped to 1381W but consumption has also dropped to 1354W. Now the site is 100% self-sufficient and are only using 98% of their generation with a surplus of 27W being exported to the grid.
