SOLARSurge Protection and Waveform correction
Solar generation can have a positive impact on energy prices and global warming. As the generation of solar power increases, some tough questions about the generation process need to be answered. Solar power, unlike other power, is generated in direct current (DC). However, the electrical distribution system requires alternating current (AC). This means solar power must be inverted from DC to AC before the power can be usable. However, inverting DC to AC creates “switching noise” and power pollution on the fundamental waveform. Other nonlinear loads can also generate the same switching noise in the home, such as the HVAC system, refrigerators, motors, TV, and EV charging stations.
Solar inverters both generate and receive noise:
As a nonlinear load, the solar inverters generate switching noise to the electrical distributions system. At the same time, the inverters are being negatively impacted by the noise from other nonlinear loads in the facility, such as HVAC, VFD’s, and LED lighting.
Switching noise shortens life of your electrical loads:
Untreated noise freely propagates in the electrical system from load to load, including the inverters – causing potential harm to the electrical loads, resulting in erratic behavior, decreased longevity, lower efficiency, etc.
The damaging effects of noise may not be seen instantaneously, but it’s a slow process altering the capacitive reactance of the unit. As the capacitive reactance decreases, the inverter is prone to attract more transients, and thus its premature damage. On average, a typical residential solar installation requires upwards of $3000 for an inverter repair and replacement, and it is crucial to protect your investment with suitable noise filters.
EP filters are specifically designed to remove the switching noise generated by the solar inverters and protect your residential/commercial facility from noise and transients. EP filters also protect the solar inverters and increase their longevity. EP filters have an additional high-frequency noise module that can attenuate noise in the 10kHz range. 10kHz noise is substantial enough to malfunction the sensitive electronic loads in your facility. All our filters are UL listed, CSA EMI filters, and are Made in the USA.
