SRNE 60kW 3-Phase High-Voltage Industrial Solar System

1. System Overview

The SRNE IESP600SH3 60kW 3-Phase High-Voltage Industrial Solar System is a powerful commercial and industrial solar power solution designed to provide reliable electricity for businesses, institutions, farms, workshops, commercial buildings and other facilities with substantial energy requirements.

The system combines high-efficiency Jinko monocrystalline solar panels, a 60kW SRNE three-phase high-voltage inverter, and a large 140kWh lithium battery storage system. This configuration allows solar energy generated during the day to power the premises while excess energy can be stored in the lithium battery bank for use when solar production is low or unavailable.

The system is designed for three-phase electrical applications and can provide a dependable combination of solar generation, battery backup and grid power through the automatic changeover system.

4. 140kWh High-Voltage Lithium Battery Backup

The system is equipped with a large:

140kWh Lithium Battery Storage System

The battery bank consists of:

28 × 5kWh rack-mounted high-voltage lithium batteries

28 × 5kWh = 140kWh

This provides a substantial energy reserve for use when solar power is insufficient or when grid electricity is unavailable.

Battery Configuration

• Number of batteries: 28 pieces
• Capacity per battery: 5kWh
• Total nominal storage: 140kWh
• Type: Rack-mounted high-voltage lithium battery
• Battery management: Battery Cluster Control included

The batteries are arranged into a coordinated high-voltage battery bank, allowing the system to manage a large amount of stored energy efficiently.

5. Battery Cluster Control

The system includes a Battery Cluster Control unit to coordinate the 28 lithium batteries.

The Battery Cluster Control helps with:

• Battery communication
• Monitoring of battery status
• Coordinated charging and discharging
• Battery protection
• System communication between the battery bank and inverter
• Monitoring of battery voltage and operating conditions
• Balanced operation of the battery modules

This is particularly important for a large 140kWh battery bank because multiple battery modules need to operate as one coordinated energy-storage system.

6. Solar PV Cables

The system includes:

1,000 metres of 10mm² Solar PV Cable

Configuration:

• 500 metres RED
• 500 metres BLACK

The cables are intended for connecting the solar PV modules, combiner boxes and other DC-side components.

The red and black cable arrangement provides clear positive and negative polarity identification, helping simplify installation, maintenance and troubleshooting.

7. 12-Way Solar Combiner Boxes

The system includes:

8 × 12-Way Solar Combiner Boxes

The combiner boxes are used to organize and combine multiple solar PV strings before connection to the inverter.

They provide a centralized point for:

• Combining PV strings
• DC protection
• String isolation
• Cable organization
• Easier system maintenance

The multiple combiner boxes allow the 120 solar panels to be organized into appropriate PV strings according to the inverter’s PV input requirements.

8. DC Protection – Double Pole Breakers

The system includes:

10 × Double Pole 125A DC Breakers

These breakers provide protection and isolation for the DC circuits.

They assist in:

• Protecting circuits from excessive current
• Isolating sections of the PV system
• Improving maintenance safety
• Protecting electrical equipment and cabling

The final breaker arrangement should be installed according to the actual PV string configuration and the electrical ratings of the selected equipment.

9. Lightning Protection

The system includes:

4 × Lightning Arresters

Lightning protection is particularly important for solar installations because the PV modules and mounting structures are exposed to outdoor weather conditions.

The lightning protection equipment helps protect the solar electrical system from transient voltage surges caused by lightning and electrical disturbances.

10. Earthing System

The package includes:

4 × Earth Rods

Proper earthing is an important part of the installation and provides a controlled path for fault and surge currents.

The earthing system is intended to improve:

• Personnel safety
• Equipment protection
• Lightning protection
• Surge protection
• Overall electrical system safety

The final earthing arrangement should be installed and tested by a qualified electrician in accordance with applicable electrical requirements.

11. Three-Phase Automatic Changeover Switch

The system includes a:

Three-Phase Automatic Changeover Switch

The automatic changeover switch allows the system to automatically manage the transition between available power sources, such as solar/inverter output and grid supply, according to the configured operating mode.

This helps ensure continuity of power to important loads and reduces the need for manual switching during power interruptions.

12. Aluminium Solar Mounting Rails

The system includes:

64 × 4.8-metre Aluminium Long Rails

Total rail length:

64 × 4.8m = 307.2 metres

The aluminium rails form part of the PV mounting structure used to securely support the solar modules.

Aluminium mounting rails are suitable for solar applications because they are:

• Lightweight
• Strong
• Corrosion resistant
• Easy to install
• Suitable for long-term outdoor use

13. Busbars

The system includes:

2 × Busbars

Busbars provide a common electrical connection point for distributing current between relevant system components.

They help provide:

• Organized electrical connections
• Reduced cable congestion
• Easier maintenance
• Efficient current distribution

14. AC Cabling

The system includes:

16mm² Single-Core AC Cable – 6 Rolls

The AC cables are used for appropriate AC connections within the system, including connections between the inverter, distribution/protection equipment and designated loads, depending on the final installation design.

The actual cable routing and number of conductors required should be confirmed against the final system design, cable run lengths, installation method and applicable current-carrying requirements.

15. Battery Protection

The system includes:

250A Battery Fuse

The high-current battery fuse provides protection for the battery circuit against excessive current and short-circuit conditions.

It also provides an additional level of protection between the high-voltage battery bank and associated power equipment.

16. System Energy Flow

The system operates through several coordinated stages:

During Sunny Hours

120 × 635W Jinko Solar Panels → 76.2kWp Solar Array → SRNE 60kW Inverter → Loads

The solar panels generate electricity during the day. The inverter converts and manages the generated power for use by the three-phase loads.

Where solar production exceeds the instantaneous load demand, available excess energy can be directed toward charging the battery bank, subject to the inverter and battery operating limits.

When Solar Production Falls

The system can draw energy from the:

140kWh Lithium Battery Bank → SRNE Inverter → Connected Loads

This allows stored solar energy to continue supporting the premises when solar generation is reduced.

During Grid Outage

The battery bank can provide backup power through the inverter to the supported loads, subject to the actual load demand, battery state of charge and the inverter’s backup/load specifications.

The automatic changeover system helps manage the transition between the available power sources.
