Because electricity is in high demand, realistically we need to triple grid capacity over the next 30 years by both energy efficiency and generation or face grid instability. We are failing to do so, therefore inevitably the grid will become unstable.
Systems selling power to Utilities without energy storage can not operate in blackouts and the utility grid is becoming more volatile
The cost to upgrade these systems is very high because with current technology, it’s necessary to take out and destroy existing components such as inverters and wiring to accomplish the modification.
Current technology does not exist that can effectively provide a perfect universal upgrade of low cost energy storage to these existing “grid tie” (power plants that sell to utility) systems without enormous expense.
Additionally no one has ever made a micro 230W solar battery backup system that was also a grid tie.
Thanks to Gridlink Systems new technology we can upgrade virtually any grid tie system to battery backup for as little as $2000 in material costs- thousands, even tens of thousands less than our competitors.
