5kw-infini-v

Overview

The 5kW Infini-V is a model of hybrid solar inverter from the Infini series, most famously manufactured by Voltronic Power. Voltronic is a major Taiwanese OEM that produces inverters sold under many brands (like Axpert, InfiniSolar, etc.). The “Infini” series is their high-end line, and the “V” typically denotes advanced features and a graphical display.

It is an all-in-one unit that combines a solar charge controller, a battery inverter/charger, and a grid-tie inverter into a single device. It’s designed for on-grid, off-grid, and backup power applications, making it one of the most versatile inverters on the market.

Key Features & Capabilities

1. True Hybrid Operation:

   • Grid-Tied: Can feed solar power into your home and export excess to the grid (where local regulations and net metering allow).

   • Off-Grid: Can disconnect from the grid and power your home solely from solar and batteries (islanding).

   • Backup Power: Provides seamless, automatic switchover to battery power during a grid outage.

2. Solar Charger (MPPT):

   • Capacity: Up to 5,000 watts of solar panels.

   • MPPT Technology: A high-efficiency Maximum Power Point Tracker optimizes energy harvest from the solar array.

   • High PV Voltage: Typically supports high DC input voltages (e.g., 115VDC – 430VDC), allowing for longer, thinner wire runs and better efficiency.

3. Battery Inverter/Charger:

   • Output Power: 5,000 VA / 5,000 W (continuous).

   • Output Waveform: Pure Sine Wave, essential for safely running sensitive electronics like laptops, medical equipment, and variable-speed motors.

   • Charging: Can charge the battery from three sources: Solar (priority), the Grid, or a Generator.

4. Advanced Power Management Logic:
   This is a core strength. Users can program the inverter with different modes:

   • Solar First: Use solar to power the load and charge the battery. Only use the grid if solar and battery are insufficient.

   • Grid-Feeding (Export): Send excess solar power to the grid.

   • Backup Mode: Keep the battery charged for use only during a grid outage.

   • Time-of-Use (TOU) Management: Set the inverter to use cheap grid electricity at night to charge the battery and then use the battery during expensive peak daytime hours.

Typical System Configuration

A 5kW Infini-V system would typically include:

• 5kW Infini-V Inverter: The central unit.

• Solar Array: Up to 5kW of panels (e.g., 12-13 x 400W panels).

• Battery Bank: A 48V battery bank, commonly with lead-acid (AGM/Gel) or, more modernly, Lithium-Ion (LiFePO4) batteries. The capacity is customizable (e.g., 10kWh, 20kWh).

• Critical Loads Panel (Optional but Recommended): A separate electrical sub-panel that powers essential circuits (lights, fridge, outlets, etc.) that will remain on during a grid outage. This prevents overloading the inverter.

Who is it For?

The 5kW Infini-V is ideal for:

• Homeowners seeking energy independence and protection from power outages.

• Users in areas with unstable grids or frequent blackouts.

• Those with high electricity rates and net metering, wanting to maximize self-consumption and potentially earn credits.

• Tech-savvy users who want to customize and monitor their energy usage in detail.

Advantages

• All-in-One Solution: Saves space, simplifies wiring, and can be more cost-effective than buying separate components.

• Extreme Versatility: Functions in nearly any scenario (on-grid, off-grid, backup).

• Uninterruptible Power Supply (UPS) Functionality: Seamless switchover (<10ms) during blackouts.

• Advanced Monitoring: Comes with software for detailed monitoring and control via a computer or smartphone app.

Important Considerations & Potential Drawbacks

• Complexity: Setup and programming are more complex than a simple grid-tie inverter. It requires a knowledgeable installer.

• Grid Compliance: You must ensure the model is certified for grid-connection in your country (e.g., UL1741 for USA, G99/G100 for UK, VDE-AR-N 4105 for Germany).

• Battery Dependency: To function as a backup during an outage, a battery is mandatory.

• Branding: Since Voltonic manufactures for others, you might find the same hardware under different brand names, with varying levels of warranty and support.

Summary

In essence, the 5kW Infini-V is a powerful and sophisticated hybrid inverter that gives a homeowner complete control over their energy. It’s not just a solar inverter; it’s an integrated energy management system. It allows you to use solar power in real-time, store it for later, sell it back to the utility, and keep your lights on when the grid goes down, all from a single, compact unit.
