Off grid solar power systems are becoming more and more popular. There are many benefits to these solar panels that keep people interested in them. In this blog, you can learn what is the off grid solar power system, what should we know before making the system, and how to make the off grid solar system.
What is off grid solar power system?
Off grid solar system is made up of a solar panel, solar charge controllers, inverter, and battery. When there is solar, the system generates power from solar, providing power to load and charging batteries via a solar charge controller at the same time. When there is no solar or the solar is insufficient, the inverter discharges the power from the battery and converts it into AC power for home appliances or equipment. The system is economical and environmentally friendly. It is widely used in an area with power shortages.
What do we need to know before offering off-grid solutions?
- The load status such as the total load power, what is the load type (inductive or not), will determine what inverter power should we choose.
- The daily power consumption and the battery backup hours, are very important to help calculate the solar panel power and battery capacity.
- The project location for installation can influence the sunshine hours and solar panel qty.
How to do the off grid solar power system solution?
The power of the inverter should be 1.2-1.5 times the load power. If there is an inductive load such as an air conditioner, which needs a big current to start, the power of the inverter should be 3-5 times the load power
2). Solar panels:
Depends on the power needs and the sunshine status. Solar panels power= the daily power needs/ sunshine hours/ the efficiency
3). Solar charge controller:
The solar charge controller depends on the power of the solar panels and system Voltage. The solar charge controller capacity=the power of panels/vmp of panel
Depends on the backup time The battery capacity= the power needs/system voltage/DOD &efficiency
