Grid Hybrid Solar Systems

Ever wanted the security of knowing that you can rely on your own power supply if the electricity system fails? This is now possible with the latest technology which combines grid connect solar power with battery backup. In most cases you will not even know that there is a blackout as your system will automatically switch over to battery power. An added advantage of having your own battery storage is that you can choose to use your stored power at times when the electricity prices are especially high. These systems need to be individually tailored to your own use so seeking the advice of a qualified professional who is experienced in this part of the industry is essential. Most solar installers are not experienced or qualified in this field. Sunsparks Electrics has been providing off grid and grid hybrid systems since 1999.

Installing a grid hybrid system is significantly more expensive than a normal grid connect system due to the expense of batteries and a specially designed inverter as well as other necessary control gear. Here is an example of what you can expect.

  1. Amelia owns a computing and software development business. She runs numerous computers as well as air conditioning and office equipment. As well as wishing to make savings on her power bill, it is very important to her to blackout-proof her business. So a grid-hybrid system is the perfect choice. This also gives her the flexibility to use her own stored battery power at times when the peak electricity price is especially high.
