Sungrow SH15/20/25T Hybrid Solar Inverters: Advanced Protection for Long-Term Performance
In the realm of solar energy systems, protecting sensitive components against potential damage from electrical surges and ensuring the longevity of the solar panels are critical concerns. Sungrow‘s SH15/20/25T series of PV hybrid inverters are equipped with robust protective features, including DC Type II and AC Type II surge protection, and support for PID (Potential Induced Degradation) zero. This blog post will delve into these features, explaining their importance and the added value they bring to maintaining a safe, efficient, and durable solar power system.
Surge Protection: DC Type II and AC Type II
Surge protection is essential in safeguarding electrical equipment from voltage spikes that can occur due to lightning strikes or grid fluctuations. The SH15/20/25T inverters come equipped with both DC Type II and AC Type II surge protection, offering comprehensive safety against surges on both the input (solar panel side) and output (grid side).
Benefits of Type II Surge Protection
– Equipment Safety: Surge protectors are designed to absorb and dissipate the excess voltage from surges, protecting the inverter and connected devices from potential damage.
– Enhanced System Reliability: By preventing surge damage, these protections ensure the continuous operation of the solar power system, avoiding downtime and costly repairs.
Practical Implications
– High-Risk Areas: In regions prone to electrical storms or where grid stability is a concern, robust surge protection is indispensable for preventing damage.
– Long-Term Investment Security: Given the substantial investment in solar power systems, safeguarding this investment against unpredictable electrical anomalies is crucial for maximizing its lifespan and efficiency.
PID Zero: Protection Against Potential Induced Degradation
Potential Induced Degradation (PID) is a phenomenon where the voltage differences between the earthing and the active PV cells in solar panels cause a leakage of current, leading to a reduction in efficiency and lifespan of the panels. The SH15/20/25T inverters feature PID zero capability, which helps to prevent or mitigate the effects of PID.
Advantages of PID Zero
– Maintained Panel Efficiency: By preventing PID, the inverter helps maintain the optimal performance and output of solar panels.
– Extended Panel Lifespan: Addressing PID not only enhances current performance but also contributes to the long-term viability and health of the solar panels.
Practical Implications
– Large Solar Installations: In larger arrays, the risk of PID increases due to the higher system voltages. The PID zero feature is particularly beneficial in these settings, protecting the overall system’s performance.
– Geographical Considerations: In humid or coastal areas, the risk of PID is elevated due to environmental factors that can exacerbate the issue. Here, PID zero functionality is especially critical.
Conclusion: A Higher Standard of Solar Inverter Safety and Efficiency
The Sungrow SH15/20/25T series stands out not just for its power conversion capabilities but also for its commitment to safety and longevity.
