Solar battery storage systems for homes and businesses are becoming increasingly popular and affordable but with the huge array of different types of batteries and systems available it can be very overwhelming for those who are not familiar with solar and energy storage. Here we help explain the different types batteries used for off-grid systems and the many different options used for home solar battery storage.
Off-grid Solar Power Systems
Off-grid solar systems also known as stand-alone power systems (SAPS) have advanced rapidly over the last decade with a wide variety of smart inverter and lithium battery systems now available.
The shift from traditional DC coupled lead-acid batteries towards more advanced scalable lithium battery systems over the last 2 years has provided much more flexibility and options when sizing off-grid systems. In addition the reduced cost of solar panels has made it more cost effective to oversize the solar array and reduce back-up generator run time during times of prolonged bad weather.

What is a hybrid solar system?
Hybrid solar systems are connected to the grid and generate power in the same way as a more common grid-feed solar system but use lithium-ion batteries to store excess energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system... READ MORE
Many people new to solar can become overwhelmed by the number of options and complexity of the various solar and battery systems available. Here we try to explain the reasons why people choose home solar batteries and the costs involved. Going completely off-grid is also considered by many people who are sick of being ripped off by electricity retailers or by those who have chosen to live in a more remote location.
Some of the reasons people choose to install batteries or go off-grid:
Reduce cost - save money by using less energy from the grid
Reduce emissions - reduce pollution from coal/nuclear/gas power generation
Be blackout safe - Have power available during a blackout or emergency
Become energy independent - operate off-grid where possible
Reduce peak demand - peak lopping and grid stability **

With the new generation of hybrid solar inverters, complete hybrid energy storage systems and battery storage options now available on the market, we at CER have put together a summary of what's available and what's up and coming.
AC Vs DC coupled solar battery systems
AC or DC coupling simply refers to the way solar panels are coupled or linked to a battery system. Most home battery systems like the LG chem RESU are DC coupled using a hybrid solar inverter but several popular batteries such as the Tesla Powerwall and Sonnen ECO are AC batteries meaning they have an integrated inverter and are connected to the AC supply which is known as AC coupled. Being AC coupled makes it easier to add a battery storage to homes with an existing solar system.
