This package is the strongest balanced on-grid option in the selected portfolio. Thirty-six 430 Wp modules provide 15.48 kWp of solar capacity for a 15 kW Trio Plus inverter, creating a close DC-to-AC match without an aggressive panel oversize. It is aimed at businesses with a proven daytime base load and enough roof area to use the capacity properly.
Typical projects include workshops, agricultural facilities, offices, tourism properties and small commercial buildings where machinery, cooling, pumps, refrigeration or charging demand operates during solar hours. The package should be sized against actual interval data wherever possible; a 15 kW nameplate is useful only when the site can consume or legally export the production.
The official package includes a 22 kW three-phase electric vehicle charger. Because its maximum demand is higher than the solar inverter rating, the charger requires its own grid-capacity and protection assessment. Solar generation can offset part of the charging load, but the package is not a stand-alone 22 kW solar charging system.
Suitable Applications
- Workshops and small industrial or service facilities
- Farms and agricultural businesses with daytime electrical demand
- Offices, hotels, guesthouses and tourism properties
- Commercial buildings with refrigeration, cooling, pump or process loads
- Workplace or fleet charging sites with adequate utility capacity
Why This Package Is Recommended
- The 15.48 kWp array is closely matched to the 15 kW inverter.
- It creates a clear higher-capacity step without the stronger oversizing of the official Large variant.
- It is suitable for professional three-phase sites with measurable daytime consumption.
- The inverter platform leaves technical headroom for project-specific redesign, while this standard package remains easy to explain.

Important Technical and Installation Notes
- The 22 kW charger rating is higher than the 15 kW solar inverter rating. Full-power charging requires sufficient utility capacity and must be assessed together with all simultaneous building loads.
- Confirm charger inclusion, the vehicle charging standard, connector or socket version, feeder sizing, breaker, residual-current and DC-leakage protection, surge protection, earthing, communications and dynamic load management.
- If the customer does not require the charger, request an amended official bill of materials and commercial offer; do not conceal or silently remove a published component.
- The package page lists an Uno Smart Meter, whereas the Trio Plus technical sheet refers to a Trio Smart Meter option. Confirm the exact three-phase meter, current transformers, firmware, communications and export-control architecture.
- The Trio Plus sheet contains an inconsistency in its efficiency labels and values, so no exact efficiency claim is included here. Use an updated confirmed technical document if an efficiency value is needed for publication or tendering.
- This package contains no battery. The on-grid inverter shuts down when the utility supply fails and does not provide emergency power.
- Confirm the destination grid code, export approval, zero-export requirement, utility metering, protection settings and relevant certificates before quotation.
- Design the final strings using the site's minimum temperature, module open-circuit voltage, MPPT limits, input currents and actual cable routes.
- The listed mounting system is a tile-roof reference. Verify the building structure, waterproofing, wind and snow loads, fire access and mounting suitability; redesign for other roof types.
- The product page publishes cable quantities as 44 with the unit Piece. Confirm linear metres, connectors, AC cable, main-board changes, protection devices, access equipment, labour and commissioning scope.
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, including phase distribution and large starting loads
- Roof type, clear usable dimensions, orientation, inclination and structural condition
- Roof and site photographs showing shading, obstructions, access and proposed 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 or fleet details, charging standard, maximum accepted AC power and preferred cable/socket arrangement
- Intended charging schedule, simultaneous building demand and need for dynamic load management
