6 FAQs about [Photovoltaic inverter anti-pid function]

Can a PID Suppression Unit be used for photovoltaic module degradation?

Potential induced degradation (PID) is regarded as one of leading causes of photovoltaic (PV) module degradation. A PID suppression method is proposed in this paper, in which a PID suppression unit is added between DC negative bus and ground.

What is potential induced degradation (PID) of photovoltaic (PV) modules?

Author to whom correspondence should be addressed. The potential-induced degradation (PID) of photovoltaic (PV) modules is one of the most extreme types of degradation in PV modules, where PID-affected modules can result in an almost 25% power reduction. Understanding how module defects impact PID is key to reducing the issue.

Can an anti-PID inverter prevent PID?

The results of this study confirm that an anti-PID inverter is capable of preventing PID and, to some degree, other malfunctions in the PV module’s performance (e.g., leakage of current or degradation in EVA [25, 26, 27, 28, 29]). As a result, it can provide an alternative solution to hotspot recovery.

How can PV inverters reduce PID?

At the system level, apply power electronic converter technology to reduce PID (Luo et al., 2016). Based on their topologies, PV inverters are broadly classified into two types: transformer-based inverters and transformerless inverters (Kerekes et al., 2011).

How to repair PID effect in a Solis inverter?

Utilizing the internal or external PID module of the inverter, a positive bias voltage is applied to the positive and negative electrodes of the PV string to repair the PID effect. This solution offers various output modes. Current Practice: The prevailing approach involves the use of built-in anti-PID technology, mainly in Solis inverters.

Are you experiencing a PID effect in a photovoltaic plant?

In case you are dealing with unexpected and unreasonable power loss in your photovoltaic plant, you may be experiencing the PID effect in the PV modules. Potential induced degradation (PID) is a phenomenon that arises over time (months or even years).
