One of the limitations of some grid-tied photovoltaic systems is that the owner will only benefit as long as there is sunlight while the grid is functioning. Otherwise, if there is an outage, they may not even use the energy they are generating from the rooftop. During such times when the grid is disconnected, the owner can neither use the rooftop solar nor export the energy to the grid.

Owners of PV systems without backup functionalities can upgrade by adding AC coupling. This enables them to store energy and use it anytime, including during emergencies and grid outages. The AC coupling converts a simple grid-tied system into a Grid/hybrid or grid interactive system. This provides grid-ties savings whenever the grid is up and running, and off-grid independence, as well as security when there is a utility outage.

The main components of AC coupling include an energy storage system, a grid-interactive inverter/charger, a coupling device and the second panel with additional wiring for the critical loads to supply during outages.

Battery storage enables better power management by providing a number of benefits which include:

Your home could be a danger zone, and you not know it. Fifty-three percent of home fires involve electrical wiring, which remains hidden behind your walls. Don’t let the phrase “Out of sight out of mind” be a reality for you, though. Just because you don’t see the inner workings of your home wiring, it doesn’t mean problems don’t exist or can’t occur. Many electrical dangers stem from loose, frayed, or poorly installed wiring as well as from a lack of proper understanding.

Should you experience an electrical fire, do not attempt to throw water on the source! We know it may seem like the natural response, but it’s possible that you could get shocked and/or make the fire worse. In this case, the best option is to use an extinguisher that’s designed to to combat electrical fires in the initial stages. It’s incredibly important to note, however, that if it’s taking longer than five seconds to extinguish a fire, the best course of action is to call 9-1-1.

The controller keeps on monitoring the application requirement in a continuous control loop. It then commands the inverter to produce the required voltage and frequency to meet the application requirements. To do this, the controller, comprised of a microprocessor, takes the input signal from the sensor and compares this with a reference signal. It then generates the appropriate control signal for the inverter to vary its output power.

In a typical application, the controller will monitor process parameters such as pressure, flow rate, temperature or liquid level. For example, an oxygen sensor in a boiler provides a signal to adjust the speed of the fan and control the amount of oxygen in the boiler system.

Today’s drives, using microprocessors, semiconductor power switches, and SMDs are now smaller, compact, cheaper, more reliable and efficient. A typical drive will also include a filter to suppress harmonics generated when converting the DC to AC voltage.

The power that runs to our home is something we have come to rely on. There isn’t a part of our day that does not somehow use electricity. It is how we cook, tell the time, play and stay clean. When the power goes out, our lives are turned upside down. Fortunately, the power grid has been fairly stable. Unfortunately, it isn’t stable enough and the smallest thing can take it out. It is a good idea to be ready to deal with a power outage should one catch you off guard. An electrician in Burbank has some tips for putting together a power outage kit. If you have any questions about power outages or what to do, give The Electric Connection a call.

It is a good idea to put your supplies in a drawer or in a small tote stored in a cupboard in a hall closet. It needs to be easily accessed in the dark. Adding a glow in the dark sticker or two to the tote can help make it stand out.

*Talk with a Burbank electrician about having security lights installed in your home and outside. These lights will automatically turn on when the power is cut. Some of these plug into an outlet and will come on when the power goes out, providing you with instant light.

*Toss in a few emergency candles and matches along with candleholders.

*Some LED headlamps and/or flashlights is also a good idea.

*Have the number to the power company in the kit or somewhere you can easily find it.

*Keep a few cans of food on hand along with a manual can opener just in case the power outage extends into the meal periods.

You can avoid the problems created when the power goes out by having a standby generator installed by an electrician. Burbank homeowners will take comfort in having a backup source of power. Give The Electric Connection a call today and learn more about preparing for power outages.
