When lightning strikes within a mile of your solar installation or EV charging station, the resulting surge can travel through your electrical system in microseconds, destroying inverters worth thousands of dollars, frying charge controllers, and rendering expensive battery banks useless. Yet most system owners discover they need surge protection only after catastrophic failure\u2014when it’s already too late.<\/p>\n\n\n\n

These devices must withstand the 10\/350 \u03bcs impulse current waveform\u2014a slow-rising, long-duration surge that carries enormous energy content. The “10\/350” notation indicates a current that rises to peak value in 10 microseconds and decays to half that value in 350 microseconds, simulating the actual behavior of lightning current flowing
