In the rapidly evolving renewable energy landscape, Felicity Solar stands at the forefront of innovation with its groundbreaking IVGM 50K inverter, a flagship product engineered to meet the demands of large-scale, flexible, and intelligent energy storage and power conversion systems. Combining advanced control capabilities with exceptional scalability, this inverter redefines performance standards for both off-grid and hybrid applications.
1. Multi-Port Architecture for Seamless Integration
The 50K inverter features a multi-port design. On the DC side, it supports 8 PV inputs with 4 independent MPPTs and 2 high-voltage battery connections. The AC side allows for diesel generator access, grid connection, and load output. All ports are bus-decoupled, enabling each component to operate independently for optimized performance and easier control.
2. Engineered for Large System Deployments
This inverter empowers large-scale energy projects with remarkable capabilities:
- PV Access: Up to 100kW of PV capacity and 80kW input power, supporting 1.6x over-provisioning to maximize solar energy utilization.
- Battery Access: Two independent high-voltage battery inputs prevent inter-cluster circulating current. Each cluster supports up to 16 parallel groups, delivering a single-unit capacity of up to 1.92MWh.
- Inverter Scalability: Supports up to 20 parallel inverters on-grid and 12 off-grid, with a total system capacity reaching 600kW / 2.88MWh.
3. World’s First Phase-Independent On/Off-Grid Operation
It is ideal for island or remote areas with single-phase grid supply but three-phase loads. A revolutionary feature of the 50K inverter is its phase-independent control of three-phase AC output. This allows for various configurations, including:
- Full three-phase on-grid operation
- Full three-phase off-grid operation
- Hybrid combinations (e.g., Phase A on-grid while Phases B/C are off-grid)
4. Wide Voltage and Frequency Compatibility
- Designed for global deployment, the inverter supports multiple grid voltage levels:
LN:110V/LL:190V，LN:115V/LL:200V，LN:120V/LL:208V，LN:127V/LL:220V，LN:133V/LL:230V，LN:200V/LL:346V，LN:220V/LL:380V，LN:230V/LL:400V，LN:240V/LL:415V，LN:277V/LL:480V - Supports 50Hz and 60Hz frequencies, ensuring compatibility with diverse regional power infrastructures.
5. Programmable Diesel Generator Port for Smart Adaptability
The AC input port can be programmed for multiple roles:
- Diesel generator mode: Supports battery charging, dry-contact start signals, output power limits, runtime caps, thermal standby, and more.
- Smart load mode: Enables intelligent load dispatch based on preset thresholds.
- PV grid-tied inverter mode: Allows PV inverters to back-feed energy via AC coupling, with frequency-based control to disconnect when batteries are full.
6. Flexible Operating Modes for Economic Optimization
The 50K inverter incorporates intelligent operational flexibility:
- Time-of-Use pricing: Configure up to 6 independent time slots, each with tailored charge/discharge and sell power settings—perfect for arbitrage in dynamic tariff environments.
- Sell-first mode: Prioritize grid export while ensuring backup readiness.
- Anti-backflow mode for both grid and household ports: Ensures compliance with self-consumption policies and legacy solar regulations.
7. Safety and Long-Term Reliability at Its Core
- Automotive-grade LiFePO4 cells with over 6,000 charge/discharge cycles under wide temperature ranges.
- Intelligent BMS for precise current management and protection against overcharge, over-discharge, over-temperature, and over-current scenarios.
- Robust electrical design with complete isolation between high voltage, low voltage, and communication systems, enhancing insulation and EMI resistance.
Conclusion
Felicity Solar’s IVGM 50K inverter is not just a product—it’s a paradigm shift in hybrid and off-grid energy system design. Its large capacity, strong scalability, and smart control capabilities make it ideal for meeting energy needs in residential, commercial, and off-grid environments. This inverter reflects Felicity Solar’s commitment to innovation and reliability, offering a dependable solution for the evolving needs of sustainable energy systems.
