75kW Growatt Commercial Hybrid Solar Kit | 124kW Solar + 122.88kWh Battery

Put solar energy to work for your business with the 75kW Growatt Commercial Hybrid Solar Kit. This equipment package combines 200 Canadian Solar 620W bifacial panels, a Growatt WIT 75K-XHU-US inverter and two RCS-R60K battery racks for 124kW of rated solar capacity and 122.88kWh of nominal storage.

Three-Phase Power for Commercial Properties

The inverter provides 277/480V three-phase power for compatible commercial and industrial installations. Use solar during the day, store energy for later and plan backup power for priority equipment. The system can support peak-demand management when configured for your facility's usage and electricity tariff; savings depend on the project.

More Solar Energy to Use and Store

The 124kW panel array is larger than the inverter's 75kW AC rating to help capture more energy outside peak sunlight hours and provide energy for battery charging when conditions allow. The array rating is not a promise of 124kW AC output: production varies with weather, shading and system limits.

Canadian Solar Panels for Demanding Outdoor Conditions

The Canadian Solar TOPBiHiKu6 620W panels use N-type TOPCon cells and double-glass bifacial construction. They can generate additional energy from reflected light reaching the rear, depending on mounting and surroundings. Their specified -40°C to +85°C operating range and snow/wind load ratings up to 5,400/4,000 Pa support use in demanding Canadian conditions, subject to the manufacturer's mounting requirements and a site-specific structural assessment. Snow coverage still reduces production.

Battery Storage and Backup Flexibility

Two 61.44kWh RCS-R60K LiFePO4 racks provide 122.88kWh of nominal storage. The Growatt inverter supports backup operation and a compatible generator input, giving your project flexibility during outages or extended low-sun periods. Actual backup power and runtime depend on available battery energy, operating conditions and connected loads. A generator is not included.

The battery racks require dry indoor installation and a suitable temperature-controlled environment; their specified charging range is 0°C to 55°C. The inverter's IP66 enclosure does not make the battery racks outdoor-rated.

What's Included

• 1 × Growatt WIT 75K-XHU-US 75kW hybrid inverter
• 200 × Canadian Solar 620W bifacial panels — 124kW total
• 2 × RCS-R60K high-voltage battery racks — 61.44kWh each, 122.88kWh nominal total

Project Design and Optional Equipment

This is an equipment package, not a turnkey installed system. Mounting, engineered high-voltage battery distribution, interconnects, PV wiring, protection, disconnects, metering, permits and installation must be specified and quoted for your site. Tigo rapid-shutdown devices are optional purchase items and not included in the listed price; required rapid-shutdown equipment and compatibility must be confirmed for the installation.

Contact ROCKSOLAR with your location, service voltage, electricity usage and priority loads to plan the project. Grid connection and export require the applicable approvals. A third matching battery rack can be quoted for additional storage, subject to the final system design.
