6 FAQs about [Solar photovoltaic panel driving resistor]

What is a high voltage system in a PV inverter?

High voltage system in PV inverters operation requires a safe insulation resistance between the PV panel to ground. A poor insulation resistance less than 1 MΩ leads to a high leakage current (about 1 mA), which not only will damages the system but also injure the user.

What is an example of PV panel insulation resistance measurement circuit?

One example of PV panel insulation resistance measurement circuit is shown in Figure 2. Assuming that the rated voltage of the individual PV panel is 1000 Vdc during bright sunny day, good PV panel insulation resistance recorded is 2 MΩ and bad insulation resistance is 100 kΩ.

Do solar PV inverters need a ground fault detection system?

With these two trends driving the economics of solar PV inverters, the International regulatory standards require an automatic ground fault detections system to be equipped for installation of transformerless PV systems that are more than 1000 Vdc. One method is to measure the insulation resistance of each panel with respect to ground.

How do you measure the insulation resistance of a PV inverter?

One method is to measure the insulation resistance of each panel with respect to ground. This indirectly also measures the leakage current. The measurement is usually done before the turning on of the PV inverter or at least once or twice per day. For a 1000 Vdc system, normal practice requires insulation resistance to be more than 1 MΩ.

Why are transformerless PV inverter systems becoming popular?

Transformerless photovoltaic (PV) inverter systems are getting popular these days due to lower system cost, higher efficiency, easier installation and maintenance. However, since the PV panel array is usually not grounded, DC leakage current may occur between the individual PV panel and ground through parasitic capacitance.

Does series resistance affect a solar cell at open-circuit voltage?

Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
