About Sine wave inverter output voltage is low
This is caused by low intermediate circuit DC voltage. 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.

6 FAQs about [Sine wave inverter output voltage is low]
Does PWM cause a sine wave inverter voltage drop?
Whenever PWM is employed in an inverter for enabling a sine wave output, inverter voltage drop becomes a major issue, especially if the parameters are not calculated correctly. In this website you might have come across many sine wave and pure sine wave inverter concepts using PWM feeds or SPWM integrations.
How do you calculate a sine wave Vs a MSW inverter?
For a sine wave, this is exactly correct for calculating the Root Mean Square (RMS) value of a sine wave (basically, the 120 VDC voltage equivalent work of a 170 Volt Peak Sine Wave). However, a MSW (Modified Sine Wave) inverter outputs, basically, a square wave. The peak of the square wave is much less than 170 volts.
Do sine wave inverters use less bus voltage?
This type of inverters can use somewhat less bus voltage, as the peak to RMS ratio is less (w.r.t. sinewave). Pure sine wave inverters can stabilize the output voltage by changing the bus voltage and don't change the PWM signal that is fed to the full bridge driver.
Does a pure sine wave inverter work with a PWM feed?
In this website you might have come across many sine wave and pure sine wave inverter concepts using PWM feeds or SPWM integrations. Although the concept works very nicely and allows the user to get the required sine wave equivalent outputs, they seem to struggle with output voltage drop issues, under load.
How can a pure sine wave inverter stabilize the output voltage?
Pure sine wave inverters can stabilize the output voltage by changing the bus voltage and don't change the PWM signal that is fed to the full bridge driver. Other option is to keep the bus voltage at a constant level and change the PWM signal.
Can a modified sinewave inverter control the output voltage?
There can be an (optical) isolation in between. Modified sinewave inverters should control the bus voltage to regulate the AC output voltage. You may post a request for a service manual for your inverter (maybe you did already somewhere on the Internet).
