Fortress 12kW/18.5kWh Energy Storage Solution
Innovative, affordable and easy-to-install energy storage solution (ESS) that can used for both new and existing PV arrays.
World's Most Efficient
93% round-trip efficiency rate (PV-> battery-> AC load), 8- 20% higher than the competitors’
9.6 KW continuous for On-Grid production; 8KW continuous for OFf-Grid production & 20kW peak Off Grid for starting 3 ton A/C or well pumps; 18.5 KWH storage capacity per unit and is scalable to 222kWH
It can be DC coupled to new array, as well as AC coupled to existing array. DC + AC Coupling Combined supports up-to 13KW PV array
Simple to Install and Use
The plug and play solution integrate charger, inverter, auto-transfer, distribution box, monitoring all in one unit
The 12 KW hybrid inverter can be stacked-up to 9 units for a total Power Output of 108KW; 18.5 KWH Storage Capacity per unit and is scalable to 222kWH. It supports both residential (120/240V) and commercial (120/208V) application.
Safe Lithium Iron Phosphate chemistry; no cooling and ventilation is required
ALL-IN-ONE SOLUTION (GRID-TIED, HYBRID OR OFF-GRID)
Simultaneously manages power to/from Solar, Battery, Grid, Load, and Generator
- Grid Tied Mode: Sell your power to reduce your electric bill
- Meter Zero Mode: Zero your electric bill without a smart meter
- Time of Use: Use solar and batteries to minimize grid power usage when its most expensive
- Smart Load: Use a programmable output for high power off-grid items or Grid time of use items to run only when there is a lot of Solar (hot water, A/C, pumps, dehumidifier)
- Peak Shaving: Reduces your peak power demand from the grid
Fortress Power ESS uses the innovative Sol-Ark inverter, which is designed and engineered in the U.S.
