enphase grid tie
Grid-tie inverters like Enphase performactive anti-islanding. Besides pushing a sine wave of current into the grid voltage they detect (current proportional to voltage,like a resistive load except opposite polarity),they test for presence of grid by pushing some current out of phase,at the wrong time.

How does a grid tie system work?
My knowledge of grid-tie systems is woefully inadequate but, as I understand them, the system ‘brain’ matches the grid supply voltage/phase/frequency then configures each microinverter to output this to your home and the grid.
Is Enphase good for solar power?
Enphase is great for getting started with solar power! With the Enphase Inverter Solar Power Systems, we pair Enphase M250 Micro-inverters with UL listed tier oneto give you an NEC compliant system that will last for years to come.
Why choose an expandable Enphase micro-inverter system?
Choosing an Expandable Enphase Micro-inverter system will allow you start out small and expand as you are able. You can literally add one panel and one micro-inverter at a time. With a traditionalsystem, you need to anticipate power needs for your home or business during the initial design process.
Can you run a grid tie inverter off-grid?
The grid-tie inverters are supposed to be told to stop that anti-islanding stuff when off-grid. I’ve run mine with some grid-tie inverters that aren’t converted for off-grid or backup operation. So long as batteries need charge, the grid tie inverter produces all it can and Sunny Island charges its batteries.
