A 400-kVA 260V/25kV three-phase coupling transformer is used to connect the converter to the grid. The grid model consists of typical 25-kV distribution feeders and 120-kV equivalent transmission system. [pdf]
[FAQS about 400kw inverter connected to the grid voltage]
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]
