The SRNE 5kW 48V is an industrial-grade “All-in-One” hybrid inverter designed for large-scale residential power and commercial-grade reliability. Operating on a high-efficiency 48V DC architecture, this unit is built for massive scalability. Whether you need a high-capacity single-phase system or a professional Three-Phase industrial setup, this inverter is the core engine of your energy independence.
Featuring a massive 7,500W Solar Capacity and a 500V DC High-Voltage PV Input, it is engineered to maximize energy harvest while minimizing installation costs, all backed by a 2-year comprehensive warranty.
Advanced Engineering Highlights
-
Industry-Leading Parallel Scalability: Supports up to 6 units in parallel. This allows you to scale from a 5kW system up to a massive 30kW installation. It can be configured for:
-
Single-Phase Parallel: For massive power on a single line.
-
Three-Phase Parallel: To power industrial machinery and large commercial buildings.
-
-
Ultra-High Voltage PV Input (500V DC Voc): The high-voltage MPPT allows you to wire panels in long series strings. This reduces current ($Amperage$), allowing for thinner, cheaper cabling and eliminating the need for complex combiner boxes.
-
Massive 7.5kW Solar Integration: Specifically optimized to manage a heavy 7,500W solar array. This enables rapid 48V battery replenishment even while powering heavy industrial loads.
-
Pure Sine Wave Precision: Delivers grid-quality electricity ($<3\%$ THD), ensuring zero humming or damage to high-end medical equipment, servers, and sensitive appliances.
-
UPS-Grade Seamless Switching: A rapid 10ms transfer time ensures that computers and telecommunications equipment remain online without interruption during grid failure.

Versatile Applications: What It Can Run
With a 5kW continuous and 10kVA surge rating, this unit is a powerhouse:
-
Industrial & Agricultural: 4HP Motors, Borehole Pumps, and Workshop Machinery.
-
Large Residential: Multiple Air Conditioners, Electric Water Heaters, and Washing Machines.
-
Commercial: Server Rooms, Medical Clinics, and Office Buildings.
-
Whole-Home Backup: Powers everything from the kitchen to the security system simultaneously.
Safety & Intelligent Settings
-
Multiple Output Priorities: Choose between Solar First (SOL), Utility First (UTI), or SBU to optimize your savings.
-
Comprehensive Protection: Hardware-level safety for PV reverse polarity, AC back feed, short-circuit, and battery over-discharge.
-
Smart Monitoring: Fully compatible with Wi-Fi/GPRS modules for real-time mobile app tracking of your entire power plant.
Parallel & Phase Configuration Logic
This unit features a dedicated Parallel Communication Port (RS485/CAN) that allows the internal CPUs of multiple inverters to communicate in microseconds.
-
Single-Phase Parallel: Connect up to 6 units on the same phase to provide 30kW of continuous power and 60kVA of surge. Ideal for large estates with multiple air conditioners and electric water heaters.
-
Three-Phase Parallel: Configure units in multiples of three (e.g., 3, 6 units) to create a 120° phase-shifted 400V/415V Three-Phase grid. This is essential for running industrial 3-phase motors, large workshops, and commercial elevators.
-
Current Sharing: When paralleled, the units intelligently balance the load so no single inverter is stressed more than the others, extending the lifespan of the entire power plant.
Advanced Operational Features
-
Cold Start Capability: Can jump-start a “dead” system using only battery power, without needing the grid or solar panels present.
-
Dual-Controller Architecture: Uses separate microprocessors for the MPPT and the Inverter stage to ensure that a heavy AC load never interrupts the efficiency of the solar charging.
-
Intelligent Battery Management: * Dedicated BMS Communication for Lithium (LiFePO4) batteries via RS485/CAN.
-
Customizable 3-stage charging (Bulk, Absorption, Float) for Lead-Acid, Gel, and AGM.
-
-
Thermal Intelligence: Multiple high-speed, variable-frequency fans ensure the unit maintains full 5kW output even in ambient temperatures up to 55°C without derating.
