FELICITY IVPM7548-V2 7.5KVA 48V Low Frequency Inverter, Built-in 120A MPPT
The FELICITY IVPM7548-V2 is a high-capacity 7.5KVA 48V low frequency pure sine wave inverter built for demanding commercial, industrial, and off-grid installations that require transformer-grade surge handling, continuous heavy-load operation, and robust solar charging capability in a single integrated unit. Featuring a built-in 120A MPPT solar charge controller, the IVPM7548-V2 steps up from the 5KVA IVPM5048-V2 to deliver greater output capacity while retaining the low frequency transformer architecture that makes it the preferred choice for motors, pumps, compressors, and other inductive load-heavy environments.
At 7.5KVA continuous output, this inverter bridges the gap between mid-range residential solar systems and full industrial power infrastructure — making it the ideal solution for large farms, commercial cold storage, hospitality facilities, medical centres, and small manufacturing operations that need reliable, surge-tolerant, solar-backed power around the clock.
Why Step Up to the IVPM7548-V2?
While the IVPM5048-V2 serves borehole pumps and light commercial loads effectively, the IVPM7548-V2 is engineered for environments where multiple high-draw inductive loads operate simultaneously. The additional 2.5KVA of headroom means the system never operates near its limits, extending inverter lifespan, reducing thermal stress, and ensuring stable output voltage even during simultaneous motor startups across multiple circuits.
For solar installers and electrical engineers designing systems for larger facilities, the IVPM7548-V2 offers the same built-in 120A MPPT controller as the 5KVA model but with significantly more AC output capacity — delivering maximum value without requiring a separate charge controller or a jump to a full industrial inverter system.
Key Features & Specifications
7.5KVA / 7500W Pure Sine Wave Output Delivers clean, stable, grid-quality AC power at 7500W continuous rating with low total harmonic distortion (THD) across the full load range. The pure sine wave output is safe for all sensitive electronics while simultaneously capable of handling the high inrush currents of large motor and compressor startups — a combination uniquely enabled by the low frequency transformer design.
Low Frequency Transformer-Based Design The low frequency transformer at the core of the IVPM7548-V2 provides capabilities that high-frequency inverters at equivalent ratings cannot match:
- High surge capacity — sustains motor and compressor startup inrush currents typically 3× or more above rated continuous load
- Superior output voltage stability — maintains tight voltage regulation under heavy, fluctuating commercial loads
- Long-term operational durability — transformer-based construction is proven for continuous 24/7 operation in harsh industrial and agricultural environments
- Galvanic isolation — electrical isolation between input and output circuits protects connected equipment and reduces ground fault risks
- Lower harmonic distortion under heavy load — critical for facilities running variable-frequency drives (VFDs), servo motors, and precision industrial equipment
Built-In 120A MPPT Solar Charge Controller The integrated 120A MPPT charge controller delivers high-current solar charging capability, supporting large PV arrays and enabling fast, efficient battery replenishment during daylight hours. The MPPT algorithm continuously tracks peak power output from your solar panels regardless of shading, temperature changes, or panel degradation — maximizing daily energy harvest without requiring an external charge controller unit.
At 120A charging current into a 48V battery bank, the IVPM7548-V2 can deliver up to 5,760W of charging power — sufficient to rapidly recharge large battery banks between grid outages or overnight discharge cycles.
48V Battery System Compatibility Optimized for 48V battery banks across all major chemistries — LiFePO4 lithium, AGM, Gel, and Flooded lead-acid. The 48V architecture at 7.5KVA output keeps operating currents manageable, minimizing cable cross-section requirements, reducing resistive losses, and enabling longer backup runtimes from the same installed battery capacity compared to lower voltage systems.
Multiple Operating Modes Fully configurable priority modes — Solar First, Utility First, and Battery First — with adjustable AC and solar charging current settings. Facilities managers and solar installers can fine-tune energy source priority, utility import limits, and battery reserve thresholds to match specific operational and cost-saving requirements.
Wide PV Input Voltage Range Accepts a wide solar panel input voltage range, supporting diverse string configurations and compatibility with monocrystalline, polycrystalline, and bifacial solar panels across varied commercial and industrial installation designs.
LCD Display Panel A comprehensive LCD screen provides at-a-glance real-time system status — battery voltage and state of charge, solar input power and charging current, AC output load percentage, active operating mode, and input source — enabling quick operational checks without requiring remote monitoring access.
Industrial-Grade Multi-Layer Protection Comprehensive protection suite engineered for continuous commercial and industrial operation: overload and surge protection, over-temperature thermal management with automatic shutdown, short circuit protection, battery over-voltage and deep discharge protection, PV reverse polarity protection, AC input surge protection, output ground fault detection, and low battery alarm — ensuring maximum system uptime and equipment protection in demanding field conditions.
