Morning: minimal energy production, high energy needs.
Midday: highest energy production, low energy needs.
Evening: low energy production, high energy needs.
From the above, you can see the demand and production of the electricity according to different time during a day for most of the families. During the day, even if the sun has just come out just a little bit, can also charge the battery backup. Our battery provides all the power needed throughout the house.
So you can see the demand and production can’t really match up with each other.
When the sun rises, solar begins powering the home. When additional power is required within the home, the home can pull from the utility grid.
Powerwall is charged by solar during the day, when solar panels are producing more electricity than the home is consuming. Powerwall then stores that energy until the home needs it, such as when solar is no longer producing at night, or when the utility grid is offline during a power outage.
The next day when the sun comes out, solar recharges Powerwall so you have a cycle of clean, renewable energy.
That’s why the LiFePO4 powerwall batteries can optimize the usage of your solar power in your house. Under the most cases, powerwall battery charges from the excess solar energy generated during the day, and discharges to power your home at night.
Also some customers buying powerwall batteries for selling electricity to the grid. But here’re some things to note. Laws governing the connection of excess power to the public grid vary from place to place. Your personal power profile is especially important in cases where restrictions are legally imposed to prevent grid overloads during peak hours.
A simple power storage unit stores the excess energy generated in the morning, which can fully recharge the battery before the peak solar output at noon. If the battery is full at noon, the electricity generated can be fed into the public grid or stored in a fully charged battery.
And we’ve seen in the evening, is low energy production, high energy needs.
The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The generally our BSLBATT powerwall batteries will cover the energy need with the energy produced in the daytime. It heards great, but is that something missing?
In the evening, when the photovoltaic systems no longer produces any electricity, what if you need more energy than the powerwall’s energy which has been stored during the day time?
Well actually, if more energy is needed overnight, you still have access to the public power grid too. And if your household doesn’t need that much electricity, the grid can also charge the powerwall batteries if you need. However if you’ve got enough powerwall batteries for your home, there’s no need to worry about the powerwall charging at night since you’ve got enough to use.
