Most people would like to use their solar energy systems ALL the time, not just when the grid is up. With SMA’s new line of inverters, you can have electricity in your home, even if the grid is down, and without the expensive use of batteries. This means you can have a electricity when the grid is down, as long as the sun is shining!

Entero just finished another install using SMA’s new inverters, and was able to power up these basement receptacles without being connected to the grid, and without a battery bank.


The Secure Power Supply can supply electricity to the outlet on the right, when there is no grid. The switch on the right turns the Secure Power Supply on or off.

We like these inverters because they offer the best warranty in the industry, and add the value of a backup source of electricity in a typical power-out situation. For most homes, these inverters don’t cost any more than one we would typically install, and it adds security and value to the home.
