When Protection Fails: A Real Factory Incident from Kandivali—and What It Teaches Us
A costly lesson from the ground A factory owner in Kandivali (Mumbai) recently placed an order for a 100A Equipower – Mainline Voltage Protector after facing a situation most businesses never anticipate. During a routine maintenance activity, the local discom—Adani Electricity Mumbai Limited—temporarily disconnected a cable in the area. What followed was unexpected. Despite having a voltage stabilizer installed, one of the factory’s critical machines suffered…...

What Happens When Double Voltage Hits a Solar Inverter?
In certain electrical conditions like neutral failure, voltage can become highly unbalanced in a system.
This can lead to abnormal voltage levels across phases, which may damage solar inverters and connected equipment.
Such issues originate from the grid and are often misunderstood as inverter failure.
Have you seen such problems in your solar installations?

In most installations, the solar system is connected directly like this:
Grid → Solar Inverter → Load / Solar System
But the grid can sometimes experience electrical faults.
From your field experience, what kinds of grid-side electrical problems have you seen affecting equipment at sites?
For example:
• Neutral loose / neutral open
• Voltage spikes or surges
• Lightning disturbances
• Bird faults on overhead lines
• Cable damage during road digging
Are there any other electrical problems from the grid that EPCs should be aware of?
Would be great to hear the experiences from people working in different regions.
Why Do Solar Inverters Sometimes Fail Suddenly?
Many solar EPCs and installers come across situations where a solar inverter suddenly stops working, even though everything seemed perfectly normal before.
In many cases, the real reason may not be a manufacturing defect inside the inverter.
External grid-side electrical faults can sometimes cause serious damage to solar inverters. These may include:
• Neutral failure or loose neutral
• Sudden voltage spikes or surges
• Lightning disturbances
• Bird faults on overhead lines
• Accidental phase-to-phase short circuits
Such events originate from the grid side, and are often beyond the design scope of solar inverters.
This video is part of an effort to understand how frequently solar EPCs and installers encounter such situations in the field.
If you are involved in solar EPC projects, solar installations, or inverter servicing, we would love to hear your experiences.
Have you ever seen a solar inverter fail due to grid-related electrical issues?
