Sustainable Earth has designed a few “solar kits” to help you understand what can be done with solar systems , and mainly to benefit from new technologies provided by Outback or Victron such as : Grid assist , Grid zero, … One size does not fit all, but these give you an idea of what kit provides what. It clearly shows as well the HUGE differences that can exist between , for example , two ” 3 bedroom homes” ; One being “low energy” and the other being not , and having HIGH electrical consumption. Most of these kits use the “Grid-Assist” technology with the existing GRID as “back up” ; used when needed. Some are completely OFF GRID . One size does NOT fit all, so contact us for your own design , based on your REAL consumption and needs.
