The battery current will flow from positive to ground. With the negative of the battery at a lower voltage than ground, current will flow towards the negative of the battery. The current flows through the positive ground indicator (D1) and R2, and the circuit is completed to the negative of the battery.
In many markets the battery and loads are set up as floating with respect to earth ground, this means that neither the negative nor the positive of the system is grounded. Certain contaminants in the air are conductive and can create a small current path to ground.
There will in turn be no current flow through the ground detection circuit. It may be easier to picture the output as a battery and the connection to ground being a full short. When completely shorted to ground the positive side of the battery becomes zero volts. The negative side of the battery would then effectively become -120 volts.
Any wire connecting to a sensor can touch or short with another wire that is battery positive ie 12V+ so the sensor is fed directly from the battery. What will the sensor do in those conditions? Fail open circuit or fail short circuit? If short circuit then will that cause a fire or damage to other wiring?
The current flows through the positive ground indicator (D1) and R2, and the circuit is completed to the negative of the battery. As stated in the introduction “certain contaminants in the air are conductive and can create a small current path to ground.” Instead of a full short this will appear as a resistance.
When the measured resistance reaches a preset value the charger will indicate, via alarm or otherwise, that a fault has occurred. The disadvantage of this type of system is that it works well only at a fixed voltage. What is really happening during a ground fault is current flow from positive or negative to ground.
The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%.
