A UPS can help mitigate low voltage issues by supplying a stable power source when the main supply fluctuates or temporarily fails. It converts stored battery power into a consistent AC output, ensuring the inverter remains operational.
[pdf] In a nominal 220V mains installation, if voltage fluctuates to 170V or even 250V for a prolonged period, the inverter will keep switching to battery power, causing switching confusion and even protection shutdowns.
[pdf] Undervoltage protection ensures that the inverter operates within safe voltage limits, thereby avoiding potential issues caused by low voltage conditions. Low voltage can be as damaging as high voltage, leading to improper functioning and reduced efficiency of the inverter and connected devices.
