Growcol 50 kW Commercial Energy Storage System — Indoor

Bundled configuration: 50 kW three-phase hybrid inverter, Pylontech HV lithium stack (≈56 kWh), master BMS & HV cable kit, and 55 kWp PV field (100 × 550 W)

Note: Price excludes installation.

Overview

Sized for SMEs, farms, lodges and workshops that need more headroom than a 30 kW plant, the Growcol 50 kW Commercial ESS blends a 50 kW hybrid inverter, a high-voltage LFP battery (≈56 kWh) and a 55 kWp PV array. Closed-loop battery control ensures safe charging, accurate SoC and long life, while the high-voltage architecture keeps DC currents low for cleaner, more efficient installs.

Key Highlights

• 50 kW three-phase hybrid output for seamless PV + battery blending and robust backup
• ≈56 kWh HV lithium storage (10 × 5.6 kWh modules) for evening loads and outages
• High-voltage battery stack → lower DC current, slimmer cabling, higher round-trip efficiency
• Closed-loop BMS (CAN/RS485) for protection, precise SoC and warranty-compliant charging
• 55 kWp PV array (100 × 550 W) for strong daytime offset and rapid battery recharge
• Modular & serviceable design with front-access wiring and field-replaceable modules
• Comprehensive protections: OV/UV/OCP/OTP, short-circuit and insulation monitoring

Typical Applications

Retail stores, restaurants, guesthouses, workshops, filling stations; farms & packhouses (irrigation/cold rooms); clinics, schools, small office parks and telecom sites.
