Batteries and Uninterruptible Power
Solar Power Systems Perth
With the types of portable computers commonly used today we take some forms of uninterruptible electrical power for granted. Laptop computers, tablets and many other devices work via batteries that are recharged at the electrical wall socket. These devices will work while plugged to mains power, and continue to work for a few hours on battery power when unplugged. A generations or two ago this was uncommon.
Previous generations tended to use either mains powered devices or battery powered devices; the two rarely crossed over. If there was a blackout then the mains powered devices couldn’t be used. If anybody wanted to get past this then they needed an uninterruptible power supply (UPS), which stored electrical energy for use during a blackout. These worked well for short periods of time, though they were limited by the technology of the day.
Solar Battery Storage works on a similar principle to the UPS, but with the advantages of more advanced technology that provided more power for longer periods of time. A solar battery system will use the Sun’s energy during the day to charge a very large capacity battery. This battery can comfortably provide the power for a household during the night.
Battery technology has improved considerably since the 1980s. Older batteries used nickel-cadmium technology which suffered from a memory effect; the battery had to be fully charged and discharged each time it was used, or it could not be fully recharged in the future. The inventions of lithium-ion batteries meant that batteries could be charged and discharged as needed, with little memory effect. This was far better suited for solar systems. Older lead-acid batteries (the type used in cars) could also be used in solar system, though these were bulky and had a shorted lifespan.
