The other type of off grid system will have an inverter that converts current to AC and stores power in DC batteries.
Direct Grid-Tie Residential Solar Systems
Direct grid-tie systems need only the solar panels, an inverter and a disconnect switch to shut off power if the grid goes down.
Battery-Based Systems
We need a special inverter which in addition to converting to AC power, must feed some DC to charge the batteries, and must be able to instantly switch to battery power if the grid loses power.
Direct Grid-Tie vs Battery Based Home Solar Energy Systems
Doesn’t require wind or solar power energy with of the grid power supply running through your home, this method has been researched for a long time. A Zero point magnetic power generator is basically a Free Energy Generator.
