About The positive pole of the photovoltaic panel is connected to the negative pole of the inverter
PID occurs in systems where there is a high negative potential relative to earth. This happens if the negative pole of the inverter is ungrounded or in a bipolar configured system where the positive pole of the inverter is connected to the ground.

The article explains how to determine the positive and negative terminals of a solar panel, crucial for proper installation to avoid energy wastage. Methods include examining the diode and using a voltmeter to measure voltage. It also discusses checking solar panel polarity and fixing reverse polarity issues.
In PV plants with galvanically isolating inverters, PID can be prevented reliably by earthing the negative pole of the PV array, as this shifts the potential of the entire PV array to the positive. In PV plants with transformerless inverters which, due to their design principle, are significantly less expensive and more efficient, the required.
For a photovoltaic array, the value of the absolute potential (to the ground) at the positive pole, at the negative pole, or somewhere in-between depends greatly on the inverter’s topology. In addition, an array’s absolute potential does not necessarily remain at one level but can change constantly while in operation, also depending largely .
Wiring solar panels in series requires connecting the positive terminal of a module to the negative of the next one, increasing the voltage. To do this, follow the next steps: Connect the female MC4 plug (negative) to the male MC4 plug (positive). Repeat steps 1 and 2 for the rest of the string.

6 FAQs about [The positive pole of the photovoltaic panel is connected to the negative pole of the inverter]
What is a negative grounded solar inverter?
Also See: How to Ground Solar Inverter What is a Negative Grounded PV System? A negative grounded PV system is a solar electric system where the negative terminal of the PV solar power array is connected to the ground.
What is a negative grounded PV system?
A negative grounded PV system is a solar electric system where the negative terminal of the PV solar power array is connected to the ground. This connection is made through conductive materials like a fuse, circuit breaker, resistance device, non-isolated grounded AC circuit, or an electronic means within an inverter or charge controller.
Do solar panels have positive and negative terminals?
Solar panels feature positive and negative terminals. Wiring solar panels in series means wiring the positive terminal of a module to the negative of the following, and so on for the whole string. This wiring type increases the output voltage, which can be measured at the available terminals.
Which conductor is ungrounded on a solar PV system?
On a solar PV system, the ungrounded conductor is usually the positive (+) conductor. The negative (-) conductors are grounded, and a ground conductor bonds the system to an electric ground, as required by the local electrical code. Local utilities may require disconnects accessible by utility personnel on a grid-connected PV system.
How does a grid-connected PV system work?
A grid-connected PV system will have a circuit connecting the AC-side of the inverter to the AC service panel. Figure 16. A string inverter connected in a system converts DC energy from the solar array to AC energy suitable for household power. Inverters come in various sizes based on total system power (wattage).
Can transformerless inverters prevent negative earthing of PV modules?
In addition to negative earthing of the PV array, SMA Solar Technology AG now offers a simple technical solution to prevent this reduction in power of PV modules reliably, also when using transformerless inverters.
