Microinverters vs. String Inverters: The Future of Solar Panel Power Conversion In the rapidly evolving solar industry, the debate between microinverters and string inverters has become one of the most discussed topics among engineers, installers, and homeowners alike. Both technologies have the same core purpose—converting DC (direct current) from solar panels into usable AC (...
Boosting Solar Output in Shaded Conditions with Microinverters Shading has always been one of the biggest challenges in solar energy production. Whether it’s caused by nearby trees, chimneys, power lines, or seasonal changes in the sun’s angle, even partial shading can lead to significant power losses in a photovoltaic (PV) system. Fortunately, microinverter technology of...
Electronic Arc Suppressors: Critical Protection for Switching Systems & SVGs The Core Challenge: Destructive Arcing When mechanical switches (contactors, relays, breakers) or semiconductors (IGBTs, thyristors) interrupt current – especially in inductive DC circuits – stored magnetic energy (1/2*LI^2) generates extreme voltage spikes (V=−Ldi/dt). This ionizes air bet...
Reactive power demand and charging are important concepts in electrical power systems, particularly in the context of power quality, grid stability, and efficient energy management. Here’s an explanation of both: Reactive Power Demand Reactive power (measured in VAR, Volt-Ampere Reactive) is the power required by inductive or capacitive loads to sustain electromagnetic fields in devices...
We all know that the full name of AHF is Active Harmonic Filter, so is there such a thing as a Passive Harmonic Filter? The answer is YES! But here’s the big question — do you really understand the differences between active and passive harmonic filters, and when to choose one over the other? Let’s break it down in a way that’s easy to follow, yet technically accurate...
