AI Thread Summary

In low-voltage DC solar systems (up to 48V nominal), the necessity of grounding the lines is debated, with no clear advantage identified for either floating or grounded configurations. Grounding may only become significant if multiple systems are interconnected without a shared standard for earthing. The discussion highlights the importance of consistency in grounding practices to avoid potential issues when connecting different systems. Ultimately, the decision on grounding should consider system design and safety protocols. Proper grounding practices can enhance system reliability and safety in specific scenarios.

On a low-voltage DC Solar system(up to 48V nominal), should I leave the lines floating or one should be grounded?

I don't see any real advantage on any option...that's why I ask to confirm

I think it would only matter if two people developed their own standard and tried to connect two systems together without agreeing which side was earthed.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
