Growatt 24kW Off-Grid Solar Kit for Canadian Homes & Cottages

Generate solar power during the day and store energy for use after sunset. This off-grid solar kit combines 27 Canadian Solar 620W panels, two Growatt inverters and your choice of 2, 4 or 6 GSL batteries for your home, cottage or rural property.

Choose the Battery Storage That Fits Your Needs

Every package includes the same inverters and 16.74kW solar array. Choose a larger battery package to store more energy and run the same appliances for longer between charges.

• 2 batteries — 28.68kWh: the entry-level storage option for lower power needs when running on batteries alone.
• 4 batteries — 57.36kWh: twice the storage of the 2-battery package, with more capacity for evening and overnight use.
• 6 batteries — 86.04kWh: the most storage and battery power capability in this range, suited to customers planning for heavier loads and longer runtime.

All three options use GSL051280A-B-GBP2 IP20 indoor wall-mounted lithium iron phosphate (LiFePO4) batteries, rated 51.2V / 280Ah per battery. Runtime depends on what you power, how long you use it and the battery charge available.

Split-Phase or Three-Phase Power

Two Growatt SPE 12000US inverters can be configured for 120/240V split-phase power, commonly used in Canadian homes, or three-phase power for compatible equipment. Your installer will select the right configuration and confirm how much power is available for your equipment. Wi-Fi monitoring is included so you can keep an eye on system performance.

Canadian Solar TOPBiHiKu6 620W Bifacial Panels

The 27 Canadian Solar CS6.2-66TB-620H 620W panels provide a combined 16.74kW front-side rated solar array at standard test conditions. N-type bifacial TOPCon cells can also collect reflected light from the rear; additional production depends on mounting, ground reflectivity, shading and site conditions.

• 23.0% module efficiency for the 620W model at STC.
• Dual-glass construction: 2.0mm front and 2.0mm back glass.
• Published test loads: snow up to 5,400 Pa and wind up to 4,000 Pa, subject to specified mounting conditions.
• Hail testing: tested with 35mm ice balls according to IEC 61215.
• Dimensions and weight: 2,382 × 1,134 × 40mm; 33.4kg per panel.
• Temperature coefficient of power: −0.29%/°C.
• Operating temperature: −40°C to +85°C.

Panel ratings apply to the modules under the manufacturer’s specified conditions. Final PV string design must account for cold-weather voltage, inverter limits and installation requirements.

Optional Generator Backup

A compatible generator can provide another source of power during extended cloudy periods. Generator selection and connection details are covered in the equipment manuals and installation planning. The generator and its installation equipment are sold separately.
