The following schematic is used to measure the solar panel current. The power loss is quite low, only between 0-10A. This schematic can also used as a general purpose DC current meter. The circuit can be used as a positive or negative side of a DC circuit. The measured current which flows through the 0.01 [...]

This circuit is used to measure the current from a solar panel. It has very low power loss for currents in the 0-10A range. It also works as a general purpose DC current meter. The circuit can be used on either the positive or negative side of a DC circuit. The current to be measured [...]
