If you are not familiar with off grid solar systems, you may want to know how to get started. If you purchase a custom designed kit, which type of battery is most suitable, and so on.
How to ensure that you are not purchasing a less efficient off grid solar kit, rather than an efficient solar kit. To save time, we suggest contacting a company that can assist you. Here are some key considerations.
The components of an off grid solar system:
Solar panels
All solar systems require solar panels. The solar panel converts sunlight into direct current, which is then fed into an inverter or charging controller. You must ensure that you purchase the correct number of solar panels based on the voltage requirements and wattage information of your designed off grid solar system
Off grid battery inverter/charger
These devices allow energy to flow from solar panels to off grid batteries. In addition, they also ensure that off grid batteries receive sufficient power and receive sufficient charging. Please note that not all kits are equipped with inverters. Therefore, you may need to purchase an inverter separately.
MPPT solar charging controller (DC power supply)
The maximum power point tracker or MPPT is a DC-DC converter that optimizes the matching between solar panels (PV panels) and battery packs or public grids. Simply put, they convert the higher voltage DC output of solar panels into the lower voltage required for battery charging.
Battery pack
The battery pack will store additional energy. They work like battery storage. At night, you can use the additional power generated by the battery pack (battery storage).
Backup generator
A battery generator is an optional option. When there is a power failure, they become secondary energy sources.
The importance of off grid batteries
Therefore, you can choose between lead-acid batteries or lithium-ion batteries. Both options are available. Compared to lithium batteries, lead-acid batteries are more economical. But even if lead-acid batteries have lower costs, they still require appropriate maintenance.
You will have to check if the lead-acid battery is working properly and supplying power to your home. You can purchase lead-acid batteries online or offline. In addition, look for the possibility of battery storage. Some will require you to do battery storage.
Then you have a lithium-ion battery, called a lithium battery. Lithium iron phosphate battery will cost more, but it is more convenient to use. Lithium batteries require less ventilation and can be used even without charging. In addition, lithium-ion batteries designed using lithium iron phosphate technology require less maintenance.
Therefore, please carefully select an off grid system based on your budget and requirements, and choose solar cells, such as lead-acid or lithium batteries. In addition to everything mentioned above, you should also look for a charging controller. The charging controller regulates the current and voltage and protects the battery.
You must also purchase circuit breakers, fuses, wires, and circuit breaker boxes. Alternatively, it is possible to choose an off grid backup generator in case of a rainy day or two without sunlight. You can also search for inverters. Purchase off grid inverters based on the type of solar equipment.
