Role of the PV HUB
The electricity generated by the solar panels passes through the PV HUB, which then disperses the power, part of which is delivered to the micro inverter to load household appliances, and the excess power is stored in the battery for use at night or on cloudy days.
The PV HUB is applied to the balcony solar energy system, relying on the micro-inverter to achieve grid-connected power generation, the PV Hub to achieve solar energy storage, improve the efficiency of solar energy use, and the system intelligently controls the power output to achieve the purpose of saving the electricity bill.
It is worth noting that this balcony energy storage system is a grid-connected system, and the power stored in the battery cannot be utilised during power outages. So this system is suitable for Europe and the United States and other countries with stable power grids.
The process of developing balcony power stations
Early balcony solar power station with micro-inverter as the core, at that time this system only consists of solar panels and micro-inverter, simple installation and plug-and-play become the characteristics of this system, the main application is to generate electricity during the day to provide for the use of household loads, to achieve the purpose of saving electricity bills.
It was later felt that this system was flawed in that solar power could not be used at night or on cloudy or rainy days, and that power generated during the day could cause electricity to flow into the public grid, resulting in a waste of power.
As a result, balcony power stations with PV HUBs were promoted. The system consists of a micro inverter/solar panel/PV HUB and batteries, and during the day the solar power is generated to load household appliances for use, and the excess power is stored in the batteries, which release the power in the evening, realising the benefits of selling solar power even at night and on cloudy and rainy days.
Advantages of energy storage balcony power stations
a.Use more scenarios, wider application
b.Improve the efficiency of using solar power.
c.PV HUB adapts to most of the micro inverters, for the previous balcony power station without energy storage function, you only need to buy PV HUB and batteries can be easily realised to expand.
Disadvantages
a.Complicated installation for customers, affecting the tidiness of the balcony and affecting the efficiency of the system (too many cables)
b.Relatively high system cost
PV HUB for ACrevPOWER
ACrevPOWER team’s PV HUB adopts Zendure’s similar PV HUB, which optimises the product structure and provides a higher cost-effective price. The product supports a maximum power input of 2000W and a maximum output of 1600WZ, with intelligent cloud and app capabilities, it’s easy to set up and view, and the intelligent storage releases the power, which can satisfy more household power consumption. ACrevPOWER’s balcony solar system adopts 1600W PV HUB, users can choose to stack 2-5 kWh balcony energy storage system as needed.
