Growcol 250 kW Commercial Energy Storage System — Indoor

Bundled configuration: GW-MPS0250 250 kW three-phase hybrid inverter, Pylontech HV lithium stack (≈268.8 kWh), multi-BMS control with MBMS1000 main module, HV cable kits & 302.5 kWp PV field (550 × 550 W)

Overview

Engineered for high-duty commercial, agricultural and light-industrial facilities, the Growcol 250 kW Commercial ESS combines a 250 kW hybrid inverter, a modular high-voltage LFP battery and a ~302.5 kWp PV array. The system delivers dependable backup, peak-shaving and time-of-use optimization with closed-loop battery management and installer-friendly indoor hardware.

Key Highlights

• 250 kW three-phase hybrid output for seamless PV + battery blending and robust backup
• ≈268.8 kWh HV lithium storage (48 × 5.6 kWh Pylontech HM3A180) for extended reserve time
• High-voltage architecture → lower DC currents, slimmer cabling, higher round-trip efficiency
• Closed-loop control via CAN/RS485 for accurate SoC, optimized charge profiles and protection
• ≈302.5 kWp PV array (550 × 550 W) sized for strong daytime offset and rapid battery recharge
• Modular & serviceable design with field-replaceable modules and front-access wiring
• Comprehensive protections: OV/UV/OCP/OTP, short-circuit and insulation monitoring

Typical Applications

• Retail centres, logistics depots, workshops, cold rooms and petrol stations
• Farms & agri-processing (irrigation, packhouses, refrigeration)
• Office parks, clinics, schools, telecom and light-industrial plants
