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. [pdf]
[FAQS about The high voltage part of the inverter is low]
If your inverter voltage output is too low, consider the following possible causes and solutions:Check Mains Supply: Ensure there is no missing supply voltage phase due to blown fuses or faulty isolators1.Inspect Battery Voltage: If the battery voltage is low, recharge or replace it if defective2.Examine Connections: Loose or corroded connections can prevent proper inverter function; inspect and tighten them2.Verify Input Voltage: Ensure the input voltage to the inverter is within the required range for proper operation3.Identify Internal Faults: Look for internal faults in the inverter, such as issues with the rectifier bridge4.These steps can help diagnose and resolve low voltage output issues with your inverter.

Connect the voltage meter negative lead to the string's negative conductor. On the voltage meter, push the TEST button. Confirm the result is a positive number. If the number is negative, string polarity has been swapped. [pdf]
[FAQS about The voltage of a single inverter string is negative]
Transistor T1 is wired as a current sensor, where the resistor R1 forms the current to voltage converter. The battery voltage has to pass through R1 before reaching the load at the output and therefore the current passing through it is proportionately transformed into voltage. .
Low Battery Cut-off Threshold The low battery sensing is handled by R3 and P1 which forms a potential divider to set the base voltage of the relay driver transistor (T2). When the. .
In the above paragraphs I have explained a very simple concept of inverter overload cut-off using only transistors. However a cut off systemusing only transistors cannot be very accurate and. [pdf]
