Off-Grid Solar / Emergency Power Backup

Will My Solar Will Shut Down During a Power Outage?

Your basic grid-tied solar system will shut down during a grid outage.  Many are surprised when they hear this but it’s true.  This is a built-in safety feature which prevents solar electricity from flowing to the grid creating a hazardous condition for a utility worker that could be repairing the power lines in your area.   The inverter constantly senses grid voltage and when the grid goes down, the voltage goes to zero, and the inverter automatically shuts down.

Options exist to circumvent the situation of no power during a grid outage.

SMA Inverter with Emergency Outlet

SMA Inverter with Emergency Outlet

An SMA inverter (one type of product we install) offers an emergency outlet that can be manually switched on during a grid outage.  This islands your inverter and disconnect from the grid.  During the daytime with adequate sunshine, the inverter delivers up to 1,500 to 2,000 Watts of power to the outlet depending on model.  For a few hours of the day you can temporarily power small appliances, charge a phone or laptop, etc.  If your array is larger, you might have two or more of this type of inverter each with an outlet delivering power.

NOTE:  this type of system does not include batteries and does not store electricity.   During an outage on a cloudy day your emergency outlet may not work.  If you require more power and for longer duration, integrating batteries will be necessary.

AC-Coupled with Battery Backup

This setup is more expensive and more complex however provides the ability to interact with the grid yet provide emergency backup power during a grid outage.

This approach is recommended for the more technically savvy owner willing to learn the operation and functionality of more equipment and possible operating scenarios.

Off-Grid Solar

Off-Grid Solar

For homes that don’t have access to the utility grid or folks ready to “cut-the-cord” and adopt full energy independence, 100% off-grid is the way to go.

Off-grid solar will feature a solar array, battery bank, charge controllers, inverters, and other components.  A gas-powered generator may or may not be included.

Tick Tock Energy can help you plan, size, engineer and implement your off-grid solar system.
