Hyorid solar systems are widely used in applications where there are frequent power outages, or Photovoltaic for spontaneous self-usecannot be connected to the grid, self-use electricity prices are much more expensive than on-grid electricity prices, and peak electricityprices are much more expensive than trough electricity prices
The system consists of solar panels, battery packs, loads, hyobrid inverter and controller (allin-one machine),etc. When the sun is shining,the off grid solar aray converts solar energy into electric energy,the load is supplied by the allin-one machine, and the battery pack ischarged at the same time; when there is no sunshine, the battery powers the solarinverter with MPPT machine, and then AC load powersupply Compared with the grid-connected solar system,the hybrid solar system adds charge and discharge controlers and batteriesThe system costhas increased by about 30%, but the application range is wider. One isthat it can be set to outputat the rated power at thepeak of the electricity price to reduce electricity expenses, the second is that it can be charged in the valley of the electricily pricedischarge at the peak, and use the peak-valley price diference to make money, third, when the power grid is out of power,the solar systemworks as a backup power source continually, the inverter can be switched to off-grid working mode, and photovoltaic and storage batteriescan supply power to the load through the inverter.
