3-Phase Hybrid Inverter INVT BD 30-500KW-MT IP21 Protection Inverter(500kw)

The INVT BD 30-500KW-MT is a three-phase hybrid inverter series (30 kW up to 500 kW) designed for both on-grid and off-grid applications with integrated charging/discharging, multi-machine parallel, BMS support, and IP21 protection for indoor installations.

Models cover rated powers of 30 kW, 50 kW, 100 kW, 150 kW, 250 kW and 500 kW (max. output power: 33 kVA to 550 kVA). Choose the model to match your site load and battery bank requirements.

Maximum efficiencies range by model: up to 96.3% (30 kW), 96.5% (50 kW), 97.1% (100/150 kW), 97.3% (250 kW) and 97.5% for the 500 kW model.

Yes. It supports grid-connected charging and discharging as well as independent off-grid inverter operation with automatic on/off-grid transfer and an off-grid cold start function.

Battery voltage ranges vary by model group: BD30–100 series: 250 V–850 V (30 kW), 320 V–850 V (50 kW), 420 V–850 V (100 kW). BD150–500 series: 420 V–850 V (150 & 250 kW), 500 V–850 V (500 kW).

Rated AC output is 400 V, 3W + N + PE, frequency 50/60 Hz, operating voltage range 320 V–460 V, power factor adjustable from 1 leading to 1 lagging, and THDi < 3% when on-grid.

Yes. The inverter supports multi-machine parallel operation for capacity expansion and redundancy in larger systems.

Built-in LCD display with RS485 and CAN for BMS communication, RS485 and TCP/IP for EMS/remote monitoring. The inverter accepts real-time BMS instructions.

Protection degree is IP21 (indoor use). The product holds CE, TÜV and CGC certifications and includes integrated automatic on/off-grid switching and standard electrical protections.

Operating temperature range -30 °C to +55 °C, relative humidity 0–95% non-condensing. Maximum altitude 5000 m (derating above 3000 m). IP21 means indoor, well-ventilated installation is required.

Smart air cooling is used. Noise emission is <75 dB under normal operation; ensure adequate ventilation and clearance for airflow.

Overload capability is 110% continuous. Off-grid THDu is <1% for linear loads and <5% for nonlinear loads, delivering clean AC output for sensitive equipment.

Typical cabinet dimensions and weights: smaller models use 800 × 2050 × 800 mm (weights ~605–936 kg), mid models use 1200 × 2050 × 800 mm (~1057–1582 kg), and the 500 kW uses 1600 × 2050 × 1050 mm (~2665 kg). Exact dimensions depend on selected model.

Models have built-in transformer ratios that vary by size: examples include 100/400, 200/400, 270/400 and 315/400 depending on model to match site grid characteristics.

Yes. The manufacturer offers customization options and has extensive production experience. Standard support includes communication interfaces for BMS/EMS and integrated on/off-grid components to simplify system integration.
