There are 3 main parts to the Growatt SP2000 Storage System – The Controller, the Lithium Battery pack, and the Sensor.
The Controller can manage PV renewable energy installations from 2-8kw in total. The more renewable energy PV on the installation, the more residual power will be available to charge the Lithium Battery pack, which is a battery management system. The Controller monitors the level of renewable energy power being supplied by the PV panels, and the level of flow in and out of the property. The Controller requires a standard AC supply to plug into, so this must be considered when surveying and installation.
The Controller will prioritise the demands of the property first, then allocate any residual power to the battery management system, filling the batteries of the solar storage system, and the last thing it will do is to export to the grid. Often you will have a combination of these functions going on – power to the house, excess to the battery management system, with residual going to the grid.
The controller has an interface panel which allows you to see the status of the system at any time. There is also an LCD display screen which allows you to access a range of real-time data.
