Questions and answers
Is it possible to set the grid tide inverter to cut grid supply automatically during the day and bring back the grid supply in the night?
The HANCHU ESS HESS Series inverter supports an "Inverter priority mode," which uses DC (solar) power as the main energy source and only switches to the grid when the battery voltage is low. This allows it to automatically reduce grid usage during the day when solar power is available and switch to grid power at night if needed. Therefore, it can effectively cut grid supply during the day and restore it at night based on battery voltage and solar availability.

Mains power voltage fluctuates causing lights to dim and fridges to turn off. Can the output come through the hybrid inverter and therefore remain stable at the correct voltage.
Yes, the HANCHU ESS HESS Series hybrid inverter can stabilize output voltage during mains power fluctuations. It features full digital double closed-loop control for voltage and current, ensuring high control accuracy. Additionally, its AC-DC charge module includes an advanced control algorithm that provides stable and reliable charging with a wide AC voltage input range and full input/output protection functions.
