This package is intended for properties that require a three-phase connection but do not need a larger 10 or 15 kW inverter. Its 14-panel array provides 6.02 kWp, making it a balanced option for three-phase villas, small workshops, farm buildings and professional premises with moderate total consumption.
The three-phase inverter can manage loads across the property's phases and provide a dedicated backup supply for selected circuits after the EPS system has been correctly designed. The package should be chosen because the electrical installation is three phase, not simply because it appears more powerful than a single-phase system. Actual suitability depends on how the loads are distributed between phases and which equipment must continue operating during a grid failure.
The live product page lists an 11.5 kWh battery set. A newer Trio Hybrid K inverter sheet introduces a three-battery minimum for the 5.8/3.0 kWh battery family, while the older battery compatibility sheet and live package show two batteries. This difference must be resolved in writing before the package is published with a fixed battery capacity or quoted to a customer.
Suitable Applications
- Villas and larger residences with a three-phase grid connection
- Small workshops and professional premises
- Farm offices, control rooms and light agricultural facilities
- Properties with moderate power demand distributed across three phases
- Selected three-phase backup projects after load verification
Why This Package Is Recommended
- It provides a genuine three-phase option without moving directly to a 10 kW system.
- The 6.02 kWp solar array closely matches the inverter's 6 kW nominal output.
- It is better balanced than the 5.16 kWp Small version and requires less roof area than the Large version.
- It suits customers whose connection type, rather than total energy use, requires a three-phase solution.

Important Technical and Installation Notes
- Do not publish a fixed battery capacity or issue a final quotation until the two-battery live package has been checked against the newer Trio Hybrid K three-battery requirement.
- The live page lists an Uno Smart Meter, while current Trio Hybrid K documentation refers to a Trio Smart Meter / current-transformer arrangement. Confirm the correct three-phase metering hardware and communications equipment.
- Prepare a phase-by-phase load schedule. Total kW alone is not sufficient for selecting a three-phase backup system.
- EPS output must feed a separately designed essential-load board. Large three-phase motors, pumps and compressors require starting-current and phase-balance checks.
- Confirm the complete battery stack, battery cables, protection, battery-management-system accessories, EPS switching, neutral and earthing arrangement before quotation.
- The listed mounting components are for a tile roof; other roofs and ground installations require a new mounting design.
- Complete cold-temperature string-voltage, MPPT-current and cable-loss calculations.
- Utility approval, export permission or zero-export control must be confirmed for the destination market.
- Verify structural capacity, waterproofing, wind and snow loads, fire access, earthing, lightning protection and AC/DC surge protection.
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
- Confirmation of the three-phase connection, grid voltage and frequency
- Contracted power, main-breaker rating and any generator connection
- Load distribution across phases, where available
- List of three-phase and single-phase equipment, including motor and compressor starting currents
- Separate list of loads required during a power cut and the required backup duration
- Roof type, dimensions, orientation, inclination and structural condition
- Roof and site photographs showing shading and access conditions
- Cable distances between panels, inverter, batteries, main board and EPS board
- Whether electricity export is permitted or zero-export operation is required
- Local grid-code, utility-approval and certification requirements
- Existing earthing, lightning and surge-protection arrangement
- Proposed inverter and battery installation location, ventilation and ambient temperature
