Integrated multi-protection functions including overvoltage, undervoltage, short circuit, anti-islanding and surge lightning protection; fast fault tripping to ensure stable operation of high-power PV power stations
Class 0.2S three-phase bidirectional multi-function energy meter with independent sealed metering chamber, supporting time-of-use metering, fully meeting grid acceptance requirements for grid connection
Cold rolled steel cabinet; IP30 for indoor type / IP54 for outdoor type (IP65 optional). Wide temperature adaptability to complex indoor and outdoor conditions of industrial & commercial power stations
Standard RS485 (Modbus‑RTU) communication; optional 4G / Ethernet cloud monitoring for remote data reading, status monitoring and fault alarm
Pre-integrated and pre-commissioned before delivery; only field wiring required for commissioning, greatly reducing on-site construction and assembly workload
Power range covers 200‑400kW, supports up to 6 inverters, suitable for medium & large industrial and commercial distributed PV grid-connected projects
