Here you can see a three-phase PV installation in the city of Etropole. The maximum production capacity of the panels is 11.3kW. The plant was built with the purpose of providing an emergency power supply in case of need and meeting the power supply needs of the household.
This plant includes 19 595-watt photovoltaics with 30-year performance warranty. These are situated on a south-facing tile roof. This way they will be exposed to direct sunlight throughout the whole day.
The presence of batteries allows for the produced electricity, which exceeds the momentary power needs of the home, to be stored and used whenever it is needed. These also enable the inverter to work in off-grid mode and function even when there is a power outage, effectively making the plant act as an emergency power supply.
The inverter can be monitored remotely through a mobile app and a web portal. These contain various information regarding the momentary state of the whole PV plant, as well as historical data regarding its behavior. The various tracked indicators include the production of the photovoltaics, the state of the batteries, the power usage of the household, the eco benefits from the plant and many others. Tracking this data can help users optimize their power usage, if needed.
Here’s some pictures from the process of building the plant.
