Product Overview
The EG4® FlexBOSS21 is a cutting-edge split-phase hybrid inverter engineered for modern residential and small commercial solar energy systems. With an industry-leading 21kW of usable PV input (24kW max), it delivers up to 16kW of AC output when solar or grid is present, and maintains 12kW of continuous power in battery-only mode — ensuring energy supply around the clock, regardless of grid or sunlight availability.

Designed to work seamlessly with EG4's GridBOSS MID power gateway, the FlexBOSS21 supports 90A of utility feed-through at 120/240Vac, reducing installation costs and minimizing component requirements. Together with the GridBOSS, the system provides AC coupling, smart load management, and generator input — forming a scalable, cost-effective, and installation-friendly solar power solution. Backed by a 10-year manufacturer warranty.





Key Benefits


Unmatched PV Capacity: Industry-leading 21kW of usable PV input with a 24kW maximum input capacity — one of the highest in its class for a single 48V hybrid inverter unit.




Expandable &amp; Scalable Design: Scales effortlessly from 50 to 160 amps (equivalent to full 200A service) and supports parallel stacking of up to 10 units, making it ideal for both compact residential setups and large-scale energy systems.




High Continuous Efficiency: Delivers 16kW AC output with solar active and holds 12kW without sunlight — ensuring reliable, uninterrupted energy to loads and batteries at all hours.




Smart 3-MPPT Configuration: Three MPPTs rated at 26A / 26A / 15A support up to 5 independent strings across 3 roof orientations, maximizing energy harvest from complex or mixed-orientation arrays.




GridBOSS Integration Ready: Purpose-built to pair with the EG4 GridBOSS MID power gateway, enabling AC coupling, smart load control, and generator input — all while reducing installation complexity and cost.




Compact Footprint &amp; 10-Year Warranty: Exceptional performance in a space-saving form factor (30.4 × 22.3 × 11.2 in., 88 lbs.), backed by a full 10-year manufacturer warranty for long-term peace of mind.






How It Works
The FlexBOSS21 continuously manages power flow between solar panels, batteries, the grid, and connected loads. PV energy is prioritized for load consumption, with surplus used to charge the battery bank or export to the grid. When solar production is insufficient, the battery and grid seamlessly fill the gap — with a fast transfer time ensuring no interruption to critical loads.


Transformerless Split-Phase Topology: The high-frequency transformerless design achieves high DC-to-AC conversion efficiency while keeping the unit compact and lightweight compared to traditional transformer-based inverters.




Closed-Loop Battery Communication: Communicates via CAN/RS485 with EG4 48V lithium battery systems and other compatible brands, enabling precise state-of-charge tracking and optimized charge/discharge cycles.




90A Grid Feed-Through &amp; Pass-Through: A dedicated 90A utility feed-through allows grid power to flow directly to loads independent of inverter output limits, easily supporting high-draw appliances including 5-ton AC units, HVAC systems, and EV chargers.
