Questions and answers
Our new Mecer IVR-1200MPPT Inverter's **** is always running
The Mecer IVR-1200MPPT inverter may always be running because it is designed to provide continuous power to connected equipment. It prioritizes solar energy for power supply and switches to battery energy when solar power is insufficient. If the battery voltage drops to a low level, the inverter may use utility power as a backup. Additionally, if the inverter is configured to certain power source priorities (such as SBU mode), it will continue operating based on the available energy sources.
