Hybrid solar systems combine the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage. If you own a grid-tied solar system and drive a vehicle that runs on electricity, you already kind of have a hybrid setup. […]
An off-grid solar system (off-the-grid, standalone) is the obvious alternative to one that is grid-tied. For homeowners that have access to the grid, off-grid solar systems are usually out of question. Here`s why: To ensure access to electricity at all times, off-grid solar systems require battery storage and a backup generator (if you live off-the-grid). […]
Grid-tied, on-grid, utility-interactive, grid intertie and grid backfeeding are all terms used to describe the same concept – Grid-Tied Solar Systems that is connected to the utility power grid. Advantages of Grid-Tied Solar Systems 1. Save more money with net metering A grid-connection will allow you to save more money with solar panels through better […]
What is a transformerless inverter? Transformers The differences between standard or conventional inverters and transformerless inverters are: Conventional inverters are built with an internal transformer that synchronizes the DC voltage with the AC output. Transformerless inverters use a computerized multi-step process and electronic components to convert DC to high frequency AC, back to DC, and […]
An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in […]
Solar panels are a popular product these days, and there are many criteria to consider when deciding which panels to purchase for your solar energy system.Solar panels efficiency are a measure of how much of the sun’s energy a solar panel is able to convert into electricity under ideal, laboratory-like conditions. As you explore solar […]
The forecasted lifespan of the valve-regulated lead-acid (VRLA) UPS battery in Prostar is 3 to 5 years under recommended conditions; however, this life expectancy will fluctuate greatly depending on the following factors. Being proactive and aware of these characteristics and conditions will ensure you maximize the life expectancy of your battery and are prepared for […]
As we know, all chemical reactions are affected by temperature, and a battery relies on chemical reaction to generate power. One can easily infer that temperature does affect power of a battery. The optimum functioning of a battery is at room temperature. A slight deviation in temperature can cause changes in capacity and service life. […]
The battery bank is one of the most complicated and costly components of any off-grid power system. Lead acid batteries represent a tried and true technology that has been around for years. Flooded lead acid batteries have the lowest upfront cost, but the tradeoff comes in the form of maintenance — every month you’ll need […]
Not all batteries are made equal. Have you ever wondered why there are different battery sizes and ratings? Did you know every battery type serves a specific functionality? The two main battery types are stationary batteries and “starting” batteries. It is very important that you find the correct battery for your particular application, as the wrong […]
What are advantages and disadvantages of solar power We’re huge advocates for solar energy, but we recognize it isn’t the right solution for everyone. While solar is sustainable and ultimately cheaper than utility power in the long run, it also requires a significant up-front investment and doesn’t work for every property / roof type. The […]
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 […]
