The working principle of Off grid solar energy system
The solar panel receives sunlight and converts them into DC output during the daytime.Some the DC power is converted into AC power by the inverter to supply Household Electric Appliances, and the rest charges the battery pack.
What do you do before building an off grid system?
A solar off grid system costs a huge initial investment and the payback is long.We should consider the cost,quality,and solar efficiency at the same time on the design.There is different solar efficiency in various area.
The voltage of the system
First,you need to know what voltage of the system do you need?Sometimes we need to think long after in case you will expand your system
to larger.If you started at a small voltage,you may start over with lot of cost.
The easy way is to caculate the Max voltage of your appliances working together.The mostly implemented voltage system is 24V,48V for house.
If not start with a correct voltage,you will waste a lot of money on replacing the charger,inverter,lithium battery,etc.
