PRAG 6.5KVA/48V Heavy-Duty Inverter H-Series

PRAG 6.5KVA/48V Heavy-Duty Inverter H-Series

Model: PT-INV-6.5KVA/5000W 48V

Overview:

The PRAG 6.5KVA/48V H-Series is a high-performance Pure Sine Wave Inverter/Charger designed to deliver reliable, efficient, and robust power for both residential and commercial applications. Whether for powering sensitive electronics, large equipment, or motor-driven appliances, this inverter is equipped with features like power factor correction, advanced multi-stage charging, and superior surge capacity. The inverter ensures high performance with a peak conversion efficiency of 88%, and it can handle up to 300% overload capacity for up to 20 seconds, providing extra power when needed most.

With an output power of 5000W continuous and a 15000W surge rating (for 20 seconds), this inverter is capable of powering 5HP motors and handling demanding inductive loads without compromising safety. The system also includes a highly effective charger with a maximum charge rate of 110A, making it ideal for larger battery setups and renewable energy systems.

Key Features:

1. Pure Sine Wave Output

• Stable Power: Provides clean, smooth, and reliable pure sine wave output, essential for sensitive devices and appliances such as computers, medical equipment, and electronics.
• Bypass Mode: In the event of a grid or generator power supply, the inverter can switch to bypass mode and pass utility power directly to the load, ensuring no interruption in the power supply.

2. High Surge Capacity & Overload Protection

• Surge Capacity: Capable of handling 15000W surge power for up to 20 seconds, the inverter can support large equipment or motors without system damage, even during brief power spikes.
• Overload Capability: With a 300% overload capacity for up to 20 seconds, the inverter can reliably support sudden increases in power demand (e.g., when starting large equipment or appliances).

3. Advanced Multi-Stage Charging & Battery Management

• 4-Step Intelligent Charging: Features a sophisticated 4-step charging system (including desulphation for sulfated batteries) to ensure long-term battery health and performance.
• Up to 110A Charging Current: The system can be equipped with a charger that provides up to 110A of charging current, depending on the model, to quickly recharge batteries and maintain peak performance.
• Battery Priority Mode: Ensures the system prioritizes battery power for UPS (Uninterruptible Power Supply) functionality, making the inverter ideal for critical power backup applications.
• Depth of Discharge (DOD): Adjustable from 50%, allowing for longer battery life by controlling how much battery capacity is used before recharging.
• Desulphation Mode: Automatic de-sulphation of flat or severely discharged batteries at 15.5V for 4 hours to restore battery health.

4. Power Factor Correction (PFC) & Energy Saving

• Power Factor Correction (PFC): Reduces energy wastage and enhances the system’s overall efficiency by improving the power factor.
• Energy Saving Mode: Helps reduce power consumption when the inverter is in idle or standby mode, improving the system’s overall energy efficiency.

5. Fast Transfer Time & Seamless Operation

• Typical Transfer Time: 8ms transfer time between utility power and battery power ensures seamless power continuity for critical loads with minimal disruption.
• Load Protection: The inverter provides protection for connected loads with a 15-second delay before transfer back to AC utility power, preventing damage from power fluctuations, especially when used with a generator.

6. Rugged Design for Harsh Environments

• Durable and Reliable: Built to operate in harsh environments, the inverter is designed to be durable and reliable under extreme conditions.
• Automatic Self-Diagnostic (ASD): Includes an automatic self-diagnostic function for easier troubleshooting and maintenance.
