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. The low voltage relay will automatically disconnect the DC power between the batteries and inverter, and/or other DC devices like lights or water heating elements. When the relay disconnects, the inverter will shut down and prevent further draw on the battery or batteries. [pdf]

Central Inverters – for central inverters, the maximum input voltage is usually 1,000V. However, some newer central inverters on the market already come with a maximum input voltage of 1,500V. [pdf]
[FAQS about Central inverter voltage]
The full load operating voltage of an inverter refers to the voltage range within which the inverter can output its rated power.Generally, this range is defined by the inverter's specifications, such as the MPPT (Maximum Power Point Tracking) voltage range. For example, some inverters have a full load DC voltage range of 180 - 520 V for a 3.6 kW model, 200 - 520 V for a 4 kW model, and 230 - 520 V for a 4.6 kW model1.When the input voltage is within this range, the inverter can operate efficiently and deliver its maximum output power3.Understanding these voltage specifications is crucial for ensuring optimal performance and avoiding damage to the inverter.
