Off-grid solar energy systems is mainly composed of photovoltaic modules, controllers, inverters, batteries and other accessories
The working principle of the solar panel system is that the photovoltaic module converts light energy into direct current, and the direct current is converted into alternating current under the action of the inverter, and finally realizes the power consumption function.
It can be for Home applications, Commercial applications and Industrial applications.

Sizing solar systems can be a bit confusing with all the calculations involved, but this simplified guide will make it much easier for you.
Of course, before we decide on what panel we want to have installed, we need to have an idea of how much space is available on your roof. Typically, you also want to leave 25% of your roof free of panels for safety reasons.
The average solar system size is 17 square feet, so if you decide on the monocrystalline panels for your 5kW system then you are going to need approximately 221 square feet plus the 25% free space. This equates to a final number of 281 square feet, which is the overall space you will need.
You need a lot more space for polycrystalline panels because of their lower efficiency. Let’s take the 17 panels we calculated previously and multiply them by 17 square feet.
This gives us a value of 289 square feet. Once we add the 25% it comes to 361 square feet we need for this system.
How to choose one suitable solar off grid system?
1, confirm the inverter voltage and inverter power based on your loads
2, confirm if the system is totally off grid or with grid/generator as backup
3, confirm solar panel power based on your daily load conumption and solar irradiance figure
4, confirm battery type and battery backup hours
The 3kw off grid solar system is usually for home use where there is no grid or grid is unstable. It can supply power to normal home loads such as washing machine, LED lights, fan, air conditioner. Inverter power: 3kW AC output voltage: AC110V/120V Battery voltage: DC24V or DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
The 5kw off grid solar power system is suitable for a place where is no grid network or grid power is not stable. It can be described solar storage system with utility backup power, or grid-tied solar system with extra battery storage(no feed into grid). Inverter power: 5kW AC output voltage: AC110V/120V or AC220V/230V/240V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
