Three Phase PV String Inverter 17-30 kW Low-voltage Series
BNT017-30-KTA
The Afore Three-phase string inverters Low-voltage series are designed for commercial and power plant pV system applications, rating from 17kW to 30kW. All models with aluminum housings which is anodized, increasing durability and effectively prevents corrosion. Equipped with external inductors, ensureefficient heat dissipation, which significantly improves the reliability and extends the life of the inverters.
The inverter menu is activated by sensor touch buttons. Communication implements are via the Wi-Fi module (can be changed to Ethernet / GPRS). Check the system status anytime and anywhere via online portal APP.
