The ACU (AC Coupled Unit) serves as a pivotal component in energy storage systems,
integrating an energy storage inverter with a battery pack.
Designed for household self-consumption needs (Zero Export Mode), the ACU stores surplus
electricity generated by the PV system in its battery and converts it to alternating current (AC)
power as required. Under the time-of-use control mode, it enables charging during low-tariff
periods and discharging during peak tariff hours, aligned with user-configured time and power
settings. Additionally, the unit is equipped with an off-grid port, ensuring power supply to
critical household appliances during utility outages.
