• Backup In this mode, the EP900 acts as a reliable home backup power source that only kicks in when the grid fails. It prioritizes charging its batteries from solar energy over the grid, making it an eco-friendly and sustainable choice for your home energy needs.
Page 24
In this mode, you can customize the charge and discharge periods as well as charging power according to your specific requirements. During the charge period, the EP900 will draw power from the grid, usually making use of off-peak tariff time windows (TOU) when electricity rates are lower, to replenish its energy storage.
Page 25
With such a strategy, the EP900 ensures an efficient and reliable power supply, reducing reliance on the grid and promoting energy independence.
