Off-grid & hybrid solar power system reviews

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 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

How to select a solar battery or off-grid power system?

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 **

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. For more technical information about the types of solar, hybrid and off-grid configurations here - AC Vs DC coupled Solar battery systems
