Product FAQs
Fortress Power Product FAQs
Does energy storage work well with my solar system?
Yes. On the grid? Absolutely! Energy storage adds a lot of value to your solar systems. It keeps your solar system operating when your utility service is interrupted. Without energy storage, your PV system will be forced to shutdown when the grid is off.
If you live off grid, energy storage enables you to use the clean solar energy to power your home day and night.
Fortress Power also knows you’re a fan of conservation—energy storage saves both your surplus solar energy and your cash since it reduces on grid energy dependence.
Can I use energy storage without solar panels?
Absolutely. For on grid clients, a home energy storage unit stores energy from your electricity provider. If an outage occurs, home energy storage can provide up to 24 hours of potentially life-saving power. Need more reassurance? Fortress Power offers batteries with larger storage capabilities, completely customizable to your needs. And, like you, we appreciate saving money. When electricity is at its lowest daily rate, our smart energy storage units use that period to charge. When peak electric use occurs, our energy storage units can discharge power to suit your lifestyle.
What about power outage protection?
Power interruptions shouldn’t disrupt your schedule. An energy storage system will keep your solar system operating during grid outages. When paired with solar panels, an energy storage system supplies unlimited energy delivery. The solar panels power your home during the day and use any excess power to charge the battery. At night, the system keeps your space bright. When used without solar panels, power outage support is dependent on battery size and your energy use. Batteries providing at least 12 hours of backup power are safest.
