This version combines the 10 kW Trio Plus inverter with thirty 430 Wp modules, producing a 12.90 kWp solar array. It is intended for businesses that have enough roof area and a load profile capable of using more solar energy across the day, especially in the morning, afternoon and less favourable seasons.
The solar array is 29% larger than the inverter's rated AC output. The inverter will still export no more than its permitted AC limit, and short periods of power limiting may occur around peak conditions. The reason to choose this package is not a higher inverter rating; it is the potential to improve annual energy harvest and keep the inverter working closer to useful output for longer periods.
The official bill of materials includes a 22 kW three-phase electric vehicle charger. Its demand must be considered together with the building load and grid connection. A larger solar array can offset part of daytime charging, but it does not make a 22 kW charger independent from the utility supply.
Suitable Applications
- Commercial buildings with strong and extended daytime demand
- Workshops, small production sites and service facilities
- Hotels, guesthouses and tourism businesses
- Farms and agricultural facilities with regular daytime operation
- Workplaces with daytime vehicle charging and adequate grid capacity
Why This Package Is Recommended
- It offers a meaningful high-generation alternative to the balanced 10.32 kWp package.
- The 12.90 kWp array remains within the inverter's published 15.0 kWp PV input limit.
- The larger array can improve shoulder-hour and seasonal production.
- It suits customers who can use more annual solar energy without moving to a 15 kW inverter class.

Important Technical and Installation Notes
- The 12.90 kWp array intentionally oversizes the 10 kW inverter. Model expected clipping and annual gain before choosing it over the 10.32 kWp package.
- The array is within the published 15.0 kWp input-power limit, but that fact alone does not approve a string design. Verify cold-temperature voltage, MPPT voltage, current, parallel strings and cable losses.
- The listed 22 kW charger can exceed both instantaneous PV output and inverter rating. Confirm grid capacity, contracted demand, main breaker, feeder sizes and dynamic load management.
- Confirm whether the charger is required. If it is excluded, obtain an amended bill of materials and commercial offer rather than presenting the official package contents inaccurately.
- Specify the complete charger installation: connector or socket version, AC feeder, breaker, residual-current and DC-leakage protection, surge protection, isolation, earthing, communications and commissioning.
- The package lists an Uno Smart Meter, while the Trio Plus sheet refers to a Trio Smart Meter option. Confirm the correct three-phase meter, current transformers, firmware and export-control method.
- This package has no battery and no outage backup. Anti-islanding protection disconnects it when the grid fails.
- The tile-roof hardware is only a reference. Confirm roof structure, waterproofing, wind and snow loads, service and fire access, and redesign mounting for other roof types.
- Published cable quantities are 32 per colour with the unit Piece; confirm actual length, connector count, AC cabling and all protection equipment.
- Do not promise higher savings merely because this package has more panels. The benefit depends on the load profile, export rules, location and site-specific energy simulation.
Information Required Before Quotation
To prepare a technically correct quotation, please share:
- Destination country and project address or coordinates
- Recent electricity bills and interval load data, where available
- Three-phase grid voltage, frequency, connection type and earthing arrangement
- Contracted power, main-breaker rating and available spare grid capacity
- Detailed daytime, weekend and seasonal load profile to justify the larger solar array
- Roof type, clear usable dimensions, orientation, inclination and structural condition
- Roof and site photographs showing shading, obstructions, access and equipment positions
- Whether grid export is permitted or zero-export operation is required
- Local grid-code, utility-approval, metering and certification requirements
- Estimated DC and AC cable routes and lengths
- Existing earthing, lightning and surge-protection conditions
- Confirmation that the 22 kW electric vehicle charger is required
- Vehicle models or charging standard, maximum accepted AC charging power and preferred cable/socket arrangement
- Intended charging schedule, number of regular users and need for dynamic load management
