Solar Earthing Kits

Proper earthing (grounding) is mandatory for solar installations to protect your system from lightning strikes, electrical faults, and to ensure personnel safety. Our complete earthing kits include all components needed for a compliant installation.

As per IS 3043 and IEC 62305 standards, every solar system must have proper earthing. Our earthing kits are designed to meet all Indian electrical safety regulations and provide reliable protection for decades.

Kit Includes:

✓ Copper earthing electrode (rod)
✓ Earthing wire (copper/GI)
✓ Earthing clamps & connectors
✓ Salt & charcoal for pit
✓ GI pipe & funnel

Why Solar Earthing is Critical

⚡

Lightning Protection

Safely dissipates lightning strikes to ground, protecting equipment

🛡️

Fault Protection

Prevents electric shock from panel frame or structure faults

🔧

Equipment Safety

Protects inverter, panels, and electrical components from damage

✓

Code Compliance

Mandatory as per IS 3043 & IEC 62305 standards

Earthing Installation Steps

1

Dig Pit

Dig 3m deep pit (2ft diameter)

2

Place Electrode

Insert GI pipe/plate vertically

3

Add Salt/Charcoal

Fill layers alternately around electrode

4

Connect Wire

Attach earthing wire with clamp

5

Test & Verify

Check earth resistance < 5Ω

Standards & Requirements

Indian Standards (IS):

• IS 3043: Code of practice for earthing
• IS 732: Copper earthing electrode specification
• IE Rules 61: Earthing requirements
• IS 15081: Solar system installation
• CEA Regulations: Grid connection earthing

International Standards:

• IEC 62305: Lightning protection system
• IEC 60364-5-54: Earthing arrangements
• IEEE 142: Grounding of industrial systems
• NEC Article 690: Solar PV systems (USA reference)
• BS 7671: Electrical installation requirements

Required Earth Resistance: For solar systems, earth resistance should be less than 5 Ohms (Ω). For lightning protection, it should be less than 10 Ohms. Regular testing is recommended every 6 months.
