Yes. It is a perk for Fortress Power Commercial Customers and Residential customer who have a Fortress Power Envy Inverter.

No. Commercial customers are also eligible with an eSpire or eSpire Mini systems. Some regions have size limitations so please contact us to verify your eligibility and potential value.

Each home has different performance, and each region pays a different rate for that performance. Please see your region-specific material or contact us for a personalized answer. The value is based on how much energy you can provide the utility or market after considering your solar generation and energy usage.
It depends on the region. In Puerto Rico, it could range from 75 to 125 events per year. In New England and New York, there may be 30 to 75 events each year. In California, there could be several each week.

EnergyBroker is a Fortress Power service – available across the United States. In some regions, like Puerto Rico, the energy can only be sold to the utility. In other regions, like California, there are many buyers and sellers – it is more like our financial markets. We find the most valuable ways to use the energy and get the most value for the customer.

Most outages are driven by weather events. EnergyBroker is constantly monitoring the weather for conditions that could cause outages. If any are detected, the batteries are fully charged and remain so until the weather pattern has passed. Other shorter outages can occur at any time. EnergyBroker always reserves some battery capacity for any such outages, but the full capacity is not available right after an event.  

Absolutely. By default, EnergyBroker reserves 20% of the battery capacity for any unexpected outages. You can adjust this by emailing [email protected], the inverter display, or the Envy: Fortress Power app.

The electricity from the battery first meets the household load. If energy can be exported to the grid (this depends on the location and program), the energy physically goes to the grid and consumed by the nearest load.

It depends on the programs and markets. For example, in Puerto Rico, the EnergyBroker pays for every kWh of energy discharged from the battery for EnergyBroker. In New England and New York, the value is based on the average power level (kW) over all the events when compared to the expected consumption. In California, every event has a different value.

All electricity exported for EnergyBroker will qualify for net metering credits expect for participants in California. However, in all regions (including California) energy may be exported to maximize the financial value of your net metering credits when not providing grid services

Most battery systems are configured to charge only from a local solar array. Therefore, the energy provided is 100% clean and renewable.

No, installers just need to make sure the inverter is correctly commissioned, set up according to customer’s goal, and has a network connection.  

Systems never exceed the maximum continuous discharge rating.  However, as many events are scheduled for two hours, the battery systems actually discharge at a much lower rate.
