This can be caused by a missing supply voltage phase from a blown fuse or faulty isolator or contactor or internal rectifier bridge fault or simply low mains voltage. POSSIBLE FIXES: Check mains supply and fuses. Check operation of isolator and contactor. Check incoming voltage, this may be too low. [pdf]
[FAQS about Inverter cold voltage becomes low]
The inverter input voltage typically falls into three main categories: 12V, 24V, and 48V. These values represent the nominal direct current (DC) input voltage required for the inverter to function optimally2. The input voltage is the DC voltage that the inverter receives from external sources such as batteries or solar panels3. For solar inverters, the input voltage range is critical for efficiently converting the DC electricity from the photovoltaic (PV) array into usable AC power4. [pdf]
