Here's what you need to know before you install energy storage in your home
November 10 , 2022
After the new photovoltaic policy, many people turn their eyes to the energy storage market, and there are also many people consulting the Fu Mei son about energy storage. Today, the Fu Mei son will tell you about energy storage. As we all know, photovoltaic power stations rely on the sun to generate electricity, at night without the sun can not generate electricity, but, if the energy storage equipment is added, you can perfectly solve this problem, you can also use photovoltaic electricity at night, you can still save electricity. But, as you say, simply add energy storage? Actually, it's not all that simple.
If my family has installed a photovoltaic power station, can I add energy storage equipment?
Of course it can be added. However, the installed photovoltaic inverter needs to be replaced. Energy storage batteries need to be matched with grid-connected energy storage inverters, and existing photovoltaic inverters cannot be used.
There are two solutions on the market now. One is to add a controller to the original photovoltaic inverter to control the energy storage battery. One is to replace the original photovoltaic inverter with a grid-connected energy storage inverter.
Fu Meier inquired about the market, the cost of grid-connected energy storage inverter is a little higher, in more than ten thousand yuan. However, with the technological innovation of the major manufacturers, the cost will be lower and lower, and the model will be more and more complete.
How to choose the energy storage battery?
1) Lead acid battery
The cost is slightly lower, the disadvantage is that the short life, under the full charge and discharge state, the circulating charge and discharge times are limited, and the subsequent maintenance cost is relatively high.
2) Lithium battery
Market mainstream, the life can reach 30-40 years, the subsequent maintenance cost is low. The cost is slightly higher, now the market price is between 2000-4000 yuan / kilowatt hour of electricity, your home Ann 10 kilowatt hour of energy storage battery, the cost is between 20,000-40,000 yuan.
