The unit is a charger inverter. The charger works 100% no problem there. By the way it is 230VAC 50Hz. Most lightweight inverters first convert the low voltage to a DC high voltage (isolated). For a "true sine wave" it should be around 350VDC as the peak of 230VAC is about 325V.
So if this DC bus voltage is too low, you will never get 230Vac output voltage. "Modified sine wave" inverters use similar approach, however the full bridge is switched with 50 Hz with some dead time (instead of a PWM signal). During this dead time all switches are in the off position.
By the way it is 230VAC 50Hz. Most lightweight inverters first convert the low voltage to a DC high voltage (isolated). For a "true sine wave" it should be around 350VDC as the peak of 230VAC is about 325V. This voltage feeds a full bridge (at least 4 power switches required) and this full bridge is PWM modulated with about 20 kHz or higher.
The inverter will shut down if the input voltage from the battery drops too low (often below 10.5V). This protects the battery from damage. Recharge or replace the battery to bring the voltage back to a sufficient level. Check for a charging system failure if the battery isn’t recharging properly.
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.
Connecting to a 6V or 24V battery won’t allow the inverter to run. Locate the inverter’s fuse or breaker, usually near the DC input terminals. Check if the fuse is blown or breaker is tripped and replace/reset if necessary. If the fuse repeatedly blows, there may be a short circuit or overload causing it to fail. Further investigation is required.
