Raise a higher self-use ratio. During the day, the electricity generated by the photovoltaic is used by the load, and the excess electricity is stored in the battery; at night, the photovoltaic does not generate electricity, and the electricity from the battery is used by the load to achieve the purpose of not using the grid or using less grid electricity.
When the power grid is out of power or the power grid is unstable, it can automatically switch to the battery-powered mode. This switching time is very short (UPS effect), and the load can continue to be used.
The function of the bidirectional energy storage
inverter - photovoltaic can charge the battery, and the same grid electricity can also charge the battery (when the electricity bill is low); this way, the battery can be used to adjust the peak-to-valley electricity price difference or use it as a backup power source .
It can also be used in pure off-grid conditions to drive loads of a certain power size.
