- Product Introduction
Products eature
- All-in-One Integration (DC/AC Hub): Streamlines system wiring by combining DC power from multiple PV strings and distributing the converted AC power to loads and the grid in a single, space-saving enclosure.
- Comprehensive System Protection: Safeguards your investment with built-in overcurrent, short-circuit, and over/under-voltage protection. Features Type I/II surge protection to defend against lightning strikes and voltage spikes.
- Grid-Code Compliance & Anti-Islanding: Equipped with advanced anti-islanding and over/under-frequency protection, ensuring automatic and safe disconnection during grid outages to protect utility workers.
- Revenue-Grade Metering & Monitoring: Integrates high-precision smart meters for accurate energy measurement. Provides real-time visibility of voltage, current, and power output for optimized system performance.
- Safe & Visible Isolation: Features dedicated DC and AC disconnect switches, providing a clear, lockable point of disconnection for safe installation, commissioning, and routine maintenance.
- Rugged IP65 Outdoor Design: Built to withstand harsh environments. The IP65-rated enclosure offers superior resistance against dust, heavy rain, and UV degradation, ensuring long-term reliability in outdoor rooftop or ground-mount installations.

FAQ
Q1: Is the cabinet made of plastic or metal?
A: The BWX series features a durable powder-coated steel enclosure with an IP65 protection rating. (Note: Please verify this with your product team. If it is indeed plastic, you must specify it is UV-stabilized polycarbonate for outdoor use).
Q2: Does it include Arc Fault Circuit Interrupter (AFCI) protection?
A: The standard model includes DC/AC disconnect and surge protection. AFCI protection can be customized as an optional module to meet NEC 2026 or EU safety codes.
Q3: Can I get a customized wiring diagram for my specific inverter model?
A: Yes. We provide free engineering support and customized wiring diagrams to match your inverter (e.g., Huawei, Sungrow, Growatt) and local grid requirements.
