Growatt 36kW Off-Grid Solar Kit | 33.48kW Panels + GSL Battery

36kW Off-Grid Solar Power for Canadian Homes & Cottages

Three Growatt SPE 12000US inverters with a 33,480W array of 54 Canadian Solar 620W bifacial panels and your choice of 86.04kWh or 129.06kWh GSL LiFePO4 battery storage. A high-capacity equipment package for off-grid homes, larger cottages and rural properties, sized to suit your loads and location.

Three Growatt SPE 12000US Inverters

3 × 12,000W inverters provide a 36kW combined inverter rating with coordinated operation in your selected electrical configuration. Each inverter has dual MPPT solar charging and supports solar, battery, utility and compatible generator inputs. 

Choose Your Electrical Configuration

• 120/240V split-phase: the standard configuration for compatible home and cottage electrical systems.
• 120/208V three-phase: a separate configuration for compatible three-phase equipment, workshops and rural commercial applications. Available with either battery-storage option.

Both configurations use one shared battery bank. Gallery diagrams labelled 120/240V show the split-phase configuration only.

54 Canadian Solar 620W Bifacial Panels built for Canadian Harsh Weather

The CS6.2-66TB-620H TOPBiHiKu6 panels use N-type TOPCon cells, with 23.0% front-side module efficiency at standard test conditions. The array's 33.48kW rating excludes additional rear-side generation. Bifacial gain depends on ground reflectivity, mounting height, tilt and shading; it is not guaranteed.

Designed for demanding outdoor conditions, the panels have published ratings up to 5,400 Pa snow load and 4,000 Pa wind load, subject to specified mounting, and 35mm ice-ball testing under IEC 61215. Their operating-temperature range is −40°C to +85°C. These ratings apply to the panels, not the inverters or batteries.

Choose Your GSL Battery Storage

Both options use the same GSL 14.34kWh LiFePO4 battery. Choose six batteries for a lower initial equipment cost, or nine for more stored energy and lower current per battery at the same system load.

Installation Materials and Protection

Solar-panel racking, covered busbars, disconnects, PV wiring, rapid shutdown where required, and installation services are not included in the confirmed core-equipment list above. Confirm their supply, specifications and pricing with ROCKSOLAR before ordering.

Final PV string design must account for cold-weather voltage and bifacial current. Arrange qualified design review, installation and any required permits or inspections. Winter production, generator needs and autonomy must be assessed for the property; this package is not a promise of year-round energy independence.
