These batteries store the power produced by the solar panels and then your electrical loads draw their electricity from these batteries.
Solar panels not connected to grid.
The downside of being connected to the grid is that if there is a blackout your solar system will not work.
This means that the home will get electricity both from its solar panels and the electric grid.
Your panels will not produce energy at night but you will be using the credits that you generated during the day.
All grid tied solar systems are installed with an automatic shutoff switch which turns off your solar system in a power outage.
It stops working when the sun goes down.
For an off grid system hopefully they get everything installed quickly days few weeks the battery bank is who will be unhappy if they don t get enough charging current and or over discharged.
The downside of being connected to the grid is that if there is a blackout your solar system will not work.
All grid tied solar systems are installed with an automatic shutoff switch which turns.
This is important because solar energy is intermittent.
This could be considered a way to store energy without needing a battery system.
With a stand alone solar system the solar panels are not connected to a grid but instead are used to charge a bank of batteries.
When the sun s shining you use your fresh solar generated power when it s not you draw from the grid.
