Standalone PV systems work in remote areas independent of the utility grid, and it consists of PV array, DC/DC converter for maximum power extraction, energy storage system with bidirectional converter, and inverter to feed the AC loads. [pdf]
[FAQS about Do standalone PV systems have inverters ]
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. .
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. Overcurrent protection is implemented using R1 which is placed between the base and emitter of transistor T1. As the load current increases, the voltage drop across R1 rises. [pdf]
