The 20kW On-Grid Solar Safety Box is a high-capacity, industrial-grade protection unit designed to ensure the safe and stable operation of large-scale on-grid solar systems. Engineered to support inverters up to 20kW, this safety box integrates robust AC and DC protection mechanisms to safeguard both the solar system and the utility grid.
This unit comes pre-assembled with branded MCBs, MCCBs, SPD (Surge Protection Devices), and DC/AC isolators, ensuring protection from overload, overvoltage, short circuits, lightning strikes, and arc faults. The dual protection layers allow safe disconnection of both the DC (solar panel) and AC (grid-inverter) sides for maintenance or emergency shutdown.
Built with an IP65-certified weatherproof enclosure, the box is designed to withstand extreme weather conditions, making it perfect for rooftop, outdoor, and industrial installations. It is ideal for commercial buildings, factories, solar farms, and net metering systems requiring high-reliability protection.
