A balcony power plant system, also known as a balcony solar system or balcony photovoltaic (PV) system, is a type of solar energy system that is specifically designed for installation on balconies or terraces of residential or commercial buildings. It allows individuals or businesses to generate their own electricity using solar panels, even if they don’t have access to a large rooftop or open space.
The balcony power plant system typically consists of solar panels, mounting structures, an inverter, and electrical wiring. The solar panels are installed on the balcony or terrace, facing the sun to capture sunlight and convert it into electricity. The mounting structures securely hold the panels in place.
The electricity generated by the balcony power plant system can be used to power various electrical appliances and devices within the building, reducing reliance on grid electricity and potentially lowering electricity bills. Excess electricity can be fed back into the grid, allowing the building owner to earn credits or receive compensation through net metering or feed-in tariff programs, depending on the local regulations and policies.
Balcony Power Plant. Solar Panels + Micro inverter
But nowadays, more and more demands of balcony energy storage system coming, which is refers to a setup that combines a balcony solar power system with a battery storage system. It allows for the collection and storage of excess electricity generated by the solar panels installed on a balcony or terrace.
In a balcony solar energy storage system, solar panels capture sunlight and convert it into electricity. This electricity can be used to power appliances and devices within the building. However, during periods of low electricity demand or when the solar panels produce more electricity than is immediately needed, the excess energy can be stored in batteries instead of being fed back into the grid.
The battery storage system is responsible for storing the excess electricity generated by the solar panels. In the whole system, it typically consists of one or more batteries, a PV Hub, 2pcs of solar panel, 800W or bigger power micro inverter.
So, the question is coming, what is PV Hub and how it works?
Before this, we should understand micro inverter. Micro inverters are designed to convert the direct current (DC) electricity generated by individual solar panels into alternating current (AC) electricity that can be used in homes or fed back into the electrical grid. They are typically connected to the grid and do not have the capability to directly connect to battery storage systems.
The main reason micro inverters cannot connect directly to battery storage is that they lack the necessary circuitry and control mechanisms to manage the charging and discharging of batteries. Battery storage systems require specialized charge controllers and energy management systems to ensure efficient and safe operation.
Additionally, micro inverters are primarily designed to optimize the performance of solar panels by individually tracking and adjusting the power output of each panel. Battery storage systems have different voltage and current requirements compared to the grid, and they require specific charging profiles to ensure the longevity and efficiency of the batteries. Micro inverters are not equipped to handle these requirements.
PV Hub appeared to solve this problem. It connects to solar panel, storage battery(input), and supply power to micro inverter(output). It makes the micro inverter connect to batteries, so people can use the energy from battery at night. Another function is, PV Hub is designed to manage energy distribution. From industry aspect, PV Hub play the role of EMS(energy management system), it’s like a highly intelligent brain which knows which kind of things are in priority at different time, it can accurately adjust and distribute energies to batteries, to the grid, and to loads, always doing the best choice and action to help consumers gain the largest earnings.
