Complete Description: 5kw Infini V Series
Overview
The InfiniSolar 5kW V (also known as InfiniSolar V 5K) is a high-performance, hybrid solar inverter designed for reliable off-grid, backup, and self-consumption applications. It combines MPPT solar charging, inverter output, and grid/battery management into a single intelligent unit, making it a popular choice for residential and small commercial solar+storage systems.
5kw Infini V Series Key Features & Technology
1. Triple-Mode Operation
-
Grid-Tied Mode: Works with the grid, supplementing power and selling excess back (where permitted).
-
Off-Grid/Backup Mode: Operates independently during grid failures using battery/solar power.
-
Hybrid Mode: Intelligently blends all power sources (Solar → Load → Battery → Grid) for optimal efficiency and savings.
2. True Hybrid MPPT Solar Charger
-
Dual MPPT Trackers: Two independent inputs allow connection of two different solar arrays (different orientations, tilt, or panel types).
-
Wide Voltage Range: Typically 90-450VDC per MPPT, compatible with both 60-cell and 72-cell panel strings.
-
High Efficiency: >98% MPPT efficiency, maximizing solar harvest.
-
Max Solar Input: Up to 6.5kW (surpassing the 5kW inverter rating to ensure full charging even in sub-optimal conditions).
3. Advanced Battery Management
-
Multi-Battery Support: Compatible with Lead-Acid (AGM, Gel, Flooded) and Lithium-Ion batteries (with selectable profiles).
-
Programmable Charging: User-configurable bulk/float/equalization voltages and currents.
-
Smart Battery Protection: Features low voltage disconnect (LVD), overcharge protection, and temperature compensation (with optional sensor).
4. Pure Sine Wave Inverter Output
-
Rated Output: 5,000VA / 5,000W (4,500W continuous).
-
Surge Capacity: 10,000W+ for 5 seconds to start motors (fridges, pumps, tools).
-
Output Waveform: Pure sine wave (<3% THD), safe for sensitive electronics (computers, medical devices, motors).
-
Voltage & Frequency: 120V/240V split-phase (US models) or 230V single-phase (EU/International models), 50/60Hz selectable.
5. Intelligent Power Management & Grid Interaction
-
Zero-Export/ Limited Export: Can be configured to not send power to the grid, complying with regulations or for systems without net metering.
-
Load Shaving: Uses solar/battery power during peak grid rate hours to reduce electricity bills.
-
Generator Support: Has a dedicated AC input for generator connection with auto-start/stop control.
-
Seamless Transfer Switching: <10ms switchover time between grid and inverter power, preventing disruption to critical loads.

5kw Infini V Series Typical System Configuration
A complete InfiniSolar 5kW V system includes:
-
InfiniSolar 5kW V Inverter/Charger (the core unit).
-
Solar Array: 5-6.5kW of panels, typically split across two strings.
-
Battery Bank: A 48V deep-cycle battery bank (e.g., 4x 12V 200Ah lead-acid in series, or a single 48V 100Ah lithium battery).
-
AC & DC Disconnects: Breakers/fuses for safety and maintenance.
-
Monitoring: Optional Wi-Fi dongle for remote monitoring via smartphone app or web portal.
-
Mounting: Wall-mounted in a dry, ventilated location.
Ideal Applications
-
Home Backup Power Systems: Provides uninterrupted power during blackouts.
-
Off-Grid Homes: Primary power source in remote locations.
-
Hybrid Self-Consumption: Maximizes use of solar energy, stores excess in batteries for night use, and minimizes grid import.
-
Peak Load Shaving: Reduces demand charges for small businesses.
-
Areas with Unreliable Grids: Acts as a constant voltage/frequency stabilizer.
Pros & Cons
✅ Advantages:
-
All-in-One Design: Simplifies system design and wiring.
-
Generator Integration: Excellent for extended backup scenarios.
-
Strong Surge Power: Handles motor starts well.
-
Flexible PV Input: Dual MPPTs optimize complex roof layouts.
-
Proven Reliability: From a major manufacturer (Must Power, now part of Sol-Ark).
⚠️ Considerations:
-
Battery-Dependent: For backup operation, a sufficiently sized battery bank is mandatory.
-
Cooling Fans: Internal fans can be audible under high load.
-
Complex Setup: Initial programming requires a qualified installer for optimal performance.
-
Efficiency: While good, peak efficiency is slightly lower than some dedicated grid-tied string inverters.
Who is it For?
The InfiniSolar 5kW V is an excellent choice for:
-
Homeowners seeking energy independence and blackout protection.
-
Off-gridders needing a robust, all-in-one power center.
