Fortress & Sol-Ark
Energy Storage Solutions
Innovative, affordable and easy-to-install energy storage solution (ESS) that can used for both new and existing PV arrays. Fortress Power ESS uses the innovative Sol-Ark inverter, which is designed and engineered in the U.S.
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
Next Generation Efficiency
3X Better! Only 3.5% losses vs. 14% in today’s battery based systems
Split Phase & Three Phase
Sol-Ark’s 12K pumps out power just like the grid, allowing you to power 120V/ 240V/208V appliances
Grid-Tied, Hybrid, Off-Grid
Manages power from Solar, Battery, Grid, Load, and Generator simultaneously
Sol-Ark is expandable from 5 to 52 (16.5 kW) solar panels and 0-32 batteries. Per 12K unit.
