WHAT IS A KILOWATT HOUR? Kilowatt hour measures energy usage and production. If you’re thinking about going solar (or just want some advice on how to reduce your energy consumption), you’ve probably come across the term kilowatt-hours. But exactly what is a kilowatt hour? And why do we need to know how many we use […]
Do I need Modified Sine Wave or Pure Sine Wave Inverter? Advantages of Pure Sine Wave inverters over modified sine wave inverters: a) Output voltage wave form is pure sine wave with very low harmonic distortion and clean power like utility-supplied electricity. b) Inductive loads like microwave ovens and motors run faster, quieter and cooler. […]
Using an Inverter for Emergency Home Backup Power Using an inverter for emergency backup power is by far the most common use. The Hurricane season is here for those of you in the east and down south. I hope that this blog will help all of you to be more prepared in the likely event […]
What size inverter should I buy? We carry many different sizes, and several brands of power inverters. See our Inverters Products for specifications on each of Prostar Inverter models. Short Answer: The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate […]
What is a power inverter for? A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. In basic terms, a power inverter is a piece of equipment that […]
What is an MC4 connector (male connector & female connector) and an MC4 extension cable (8ft, 15ft, 30ft, 50ft, 100ft)? If you’re asking this question, you’ve probably noticed that most modern high power solar modules are manufactured with wire leads that have MC4 connectors on the ends. Years ago, solar modules were built with a […]
We know that solar energy is definitely a good thing, but very few of us are aware of its benefits. Thereby, this blog post is all about some benefits of solar inverter. Why is this inverter considered as the most reliable home inverter? To get the answer, just read on: Eco-friendly and reasonable: Solar energy is the cleanest […]
If you’re looking for a promising career, and care about the environment, consider being a solar panel installer. As CNBC reports, the economy is projected to swell by 11.5 million jobs over the next decade—and a significant portion of this growth will come from the workers who assemble, install, and maintain solar panel systems on roofs […]
Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept – a solar system that is connected to the utility power grid. Read more about advantages of grid tied solar system Advantages of grid tied solar system 1. Save more money with net metering A grid-connection will allow […]
A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall. […]
A photovoltaic (PV) junction box is an important part of the solar panels. The junction box is an enclosure on the module where the PV strings are electrically connected. The majority of junction box manufacturers are nowadays based in China. How is the junction box connected to the solar panel? A PV junction box is attached to […]
A new study shows that wind, water and solar generators can theoretically result in a reliable, affordable national grid when the generators are combined with inexpensive storage. Over the last few years, Mark Jacobson, a Stanford professor of civil and environmental engineering, and his colleague, Mark Delucchi of the University of California, Berkeley, have produced […]
