What is the difference between a Grid Tied system and an Off Grid system?
The main difference between the On Grid (Grid Tied) and Off Grid system is the method of energy storage for later use. On Grid, we bank energy for later use by passing excess energy production back to the grid in reverse of the energy consumption accounting system, thus applying credits for the energy that will be used later when the power production is less than the local loads require during overcast times or at night. Off Grid systems are designed to meet 100% of the current demands of the attached appliances, and electrical loads, whereas the On Grid systems are designed to meet a portion of the energy consumed by the loads, On Grid systems allow the grid to meet the high current load demand, such as high rush currents needed to start the air conditioner compressor, or other motor driven loads. This RUSH current can be 3 to 7 times the energy required to operate the appliance. In the Off Grid system the capacity of the system needs to be large enough to meet ALL current demands of
