Fortress Power EV6500-S (Solo) 6.5kW Split-Phase Hybrid Inverter
Reliable Backup & Off-Grid Power — Scalable, Flexible, and Smart
While the Solo 6.5K is only approved for indoor installations, when placed inside the Fortress Power FlexTower, it can be installed outdoors.
The Fortress Power EV6500-S is a 6.5kW split-phase / single-phase solar storage inverter designed for off-grid, backup, and hybrid energy systems. With a built-in 140A solar charge controller, dual MPPTs, and support for grid or generator input, the EV6500-S delivers dependable power management for homes, cabins, microgrids, and energy-independent projects.
This inverter is ideal for homeowners and installers who want battery-based solar with advanced load control, peak shaving, and future scalability — without the complexity of stacking multiple devices.
High-Capacity Solar Charging
Integrated 140A solar charge controller supports large PV arrays for fast, efficient battery charging — perfect for high-usage or off-grid systems.
Split-Phase 120/240V Output
Provides true 120/240 Vac split-phase power, making it compatible with standard residential loads, appliances, and sub-panels.
Grid & Generator Ready
Supports grid and generator input with intelligent switching for seamless backup power during outages or low solar production.
Time-of-Use & Smart Energy Control
Advanced scheduling allows users to optimize charge and discharge cycles, reduce peak utility costs, and manage energy strategically.
Scalable Power Platform
Parallel up to six units for a combined 39kW of output, suitable for large homes, small commercial sites, or microgrid installations.
Flexible Battery Compatibility
Works with 48V lithium-ion, lead-acid, or user-defined battery banks, offering design freedom across many storage solutions.
