Hybrid solar systems generate electric power in the similar way as a common grid-tie solar system. But it has special hybrid inverters and batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system. The system consists of photovoltaic module,solar panel mounting structure, hybrid inverter, battery pack, load, etc. The photovoltaic array converts solar energy into electric energy under the condition of light, and supplies power to the load through the hybrid inverter, and charges the battery pack at the same time. When there is no light, the battery supplies power to the hybrid inverter , and then supplies AC load power supply. Compared with the grid-connected power generation system, the hybrid system adds charge and discharge controllers and batteries, and the system cost increases by about 30%, but the application range is wider. First, it can be set to output at rated power when the electricity price peaks to reduce electricity expenses. Second, it can be charged at the valley section of the electricity price, and discharged at the peak section, making use of the difference between the peak and valley price. Third, when the power grid is out of power, the photovoltaic system can be used as a backup power supply to continue When working, the inverter can be switched to the off-grid working mode, and the photovoltaic and battery can supply power to the load through the inverter.

Advantages of off grid solar system 1. Freedom from the grid This is the main reason why people in blackout-prone regions are trend to use off-grid solar. When connected to the grid, you are dependent on an external supplier — the utility company — for all your power. When the grid shuts off, so does your power supply. But if you install off-grid solar system, it can separate your reliance to the grid. 2. Save Electric Bills The system can also allows you escape from the rapidly increasing price of the electricity. 3. Environmental friendly Going off-grid will reduces carbon emissions. Since most of the electricity supplied through the grid comes from burning fossil fuels. Solar energy is a renewable energy, it has not pollution when producing electricity. For households in areas without grid or frequent power outages, off-grid systems have strong practicality. However, the off-grid system must be equipped with a battery and occupy 30-50% of the cost of the power generation system. Economically, it is difficult to be widely used now. However, with the sharp reduction in the price of energy storage batteries and the diversification of energy storage system equipment, off grid solar systems will become more and more popular in the future.

Grid-tied solar system is the most popular type of home solar power system on the market now. It can generates power for the home. And if there have any excess power it will feeds into the grid. Corigy Grid-tie solar system consist of PV array, hybrid inverter, battery (Lithium iron phosphate or lead acid battery). It aims to store surplus energy in the battery and supply the load when needed. It’s also helpful in reducing your electricity bills and improving your energy independence. How it works? In the morning, solar power is higher than load requirement. It serves load and charges the battery at the same time. If excess energy is generated, it can be sold into mains grid. During the night when there is no sunshine, battery bank discharge power to supply the load. When there is a grid outage, the battery can be triggered to power the household applications continuously. Having a 4 milli-seconds automatic switch time, corigy residential energy storage system is able to ensure your electrical applications operation smoothly. Corigy hybrid inverter is also completely compatible with diesel generator. On Grid VS Off Grid The main advantage of a grid-tied solar system is that it has a shorter payback compared to the lifespan of an off-grid system. The average homeowner can expect to break even for the cost of a solar power system in about 8 – 10 years. The average lifespan of a solar panel system is greater than 25 years. This means that most homeowners can look forward to 15 or more years of earnings after breaking even on their investment.

The grid tie solar power system is that the direct current generated by the solar modules is converted into alternating current that meets the requirements of the mains grid through an on-gird inverter and then directly connected to the public grid. It can be divided intogrid-tiesolarpowersystemwith and without batteries. The grid-tied solar systems with a battery is schedulable, and can be merged into or out of the grid as needed, and also has the function of a backup power supply. When the grid is powered off for some reason, it can supply power in an emergency. The grid-tied solar systems with a battery with a battery is often Installed in residential buildings.Grid-tied solar systems without batteries do not have the functions of dispatchability and backup power, and are generally installed on larger systems. Compared with independently operating solar photovoltaic power plants, integration into the grid can bring many benefits to photovoltaic power generation. 1.The battery is saved as energy storage; 2.The photovoltaic array can always run at the maximum power point, and the grid receives all the electricity generated by the solar energy, which improves the efficiency of solar power generation. 3.The power grid has gained benefits, and the distributed photovoltaic system can provide electricity for local users, easing the transmission and distribution burden of the power grid. 4.Photovoltaic modules are perfectly integrated with buildings, which can not only generate electricity but also be used as building materials and decorative materials.

The off-grid solar system is mainly composed of solar modules, mounting brackets, off-grid inverters, batteries, etc. The system will first meets the need of the user's load, and then stores the excess power in the battery for use at night and in rainy days. When the battery is dead, the diesel generator can also be used as a supplementary energy source to supply power to the load. The design of the off-grid solar system is different from the grid-connected power generation system, which needs to consider the user's load, daily electricity consumption, local climate conditions and other factors. Supplier need to choose different design schemes according to the actual needs of customers. In order to ensure that the off-grid system can work reliably, it is very necessary to do a good job of customer demand investigation in the early stage. 1. Inverter selection. Determine the inverter power according to the user's load power and type The selection of inverter power should generally not be less than the total load power. But considering the service life of the inverter and subsequent capacity expansion, it is recommended that the inverter power should be considered with a certain margin. In addition, if the load contains inductive loads with electric motors such as refrigerators, air conditioners, water pumps, range hoods, etc. the starting power of the load needs to be taken into account, that is, the starting power of the load should be less than the maximum impact power of the inverter 2. Component capacity determination. Determine the component capacity according to the user's daily electricity consumption and light intensity Part of the electricity generated by photovoltaic modules during the day is supplied to the load, and the remaining part is used to charge the battery. At night or when the solar radiation is insufficient, the electricity stored in the battery will be discharged to the load for use. It can be seen that in the absence of commercial power or diesel engines as supplementary energy, all the power consumed by the load comes from the power generated by the photovoltaic modules during the day. Considering that the light intensity of different regions will be different in different seasons, in order to ensure the reliable operation of the system, the capacity design of photovoltaic panels should be able to meet the demand even in the season with the worst light. 3. Determination of battery capacity. Determine the battery capacity according to the night power consumption or backup time The battery of the off-grid solar system is mainly used for energy storage to ensure that the load can work normally when the solar radiation is insufficient. For off-grid solar systems with important loads, the design of battery capacity needs to consider the longest local rainy days. The load power supply requirements of ordinary off-grid solar systems are not high. Considering the cost of the system, the number of rainy days can be ignored, and the...
