Capacity and components (all available off the shelf except the Rotomoulded bench)
One of the two benches contains all the electronics, inverter, batteries in a cavity which is surrounded by water. This bench comes pre-assembled with all the electronics from the factory. The other bench cavities offer room for the installation of batteries with potential future capacity increase. The water in both the benches is filled on site, allowing easy transport. The advantages of the water filled benches are two folds:
PV Port & store is a hybrid system that provides the following functionalities
Connection to the house
PV Port & Store has two outputs a) for supplying to the non-critical load and b) for supplying to the critical load. There are several ways to connect PV Port & Store in the house however the recommended connection is to use a dedicated 16 A MCB at the distribution box. This eliminates any chances of MCB blinding and thus is safe to be used. For the zero export functionality, a current sensor is placed at the incoming to the distribution box and which is communicating to the inverter using a wireless zigbee connection. In case zigbee signals are not reliable, an alternative wired communication cable can also be used.
PV Port & Store comes with a sprinkler system which can be used to sprinkler water. It can be with both automatic / manual modes. The system can also provide alarms to the user every week or so to clean the system.
Monitoring and Communication
Monitoring is done via the inverter and a cheap communication method is being worked out. An APP is currently being developed which will enable the user to download the data from the inverter using the smartphone as a hotspot (no wifi, no GSM is required) and using the network of the mobile phone, the data is communicated to a central server which is populating the data on a web portal (PV Port Portal). This method is eliminating the reoccurring cost of any dedicated GSM connection for the inverter and lack of wifi signals on the roof. Where good Wifi connection is available, it will be used for constant monitoring.
