• Residential solar systems (3-6 kW setups)
• Small-to-medium commercial projects (shops, offices)
• Agricultural solar applications (water pumps, farm electrification)

Why Prices Vary: 4 Key Factors

• Material Quality: Aluminum vs. stainless-steel enclosures ($50-$150 difference)
• Safety Certifications: UL-listed boxes cost 15-20% more than uncertified alternatives
• Smart Features: Models with IoT monitoring add $80-$120 to the base price
• Brand Reputation: Established manufacturers charge 10-30% premium
