The Enphase data available on computer is brilliant, I was able to view it on line from Papua. I have been able to identify rogue appliances and replace them, adjust the use of some energy sapping units, tailor and fine tune my energy usage. I can now use more appliances while reducing the amount of energy from the grid. Happy to share some of the things I have learned, either on this site or by other contact. I will probably get two more units which will allow even more flexibility and reduce cost to a minimum. I am aware of the up front costs in achieving this, however power is going to increase in price and will justify the cost of this system, which is far less costly than most others.
