This package is the highest-capacity standard listing recommended for the category. Its 36 solar panels provide 15.48 kWp, closely matching the 15 kW three-phase hybrid inverter. It is suitable for larger villas, farms, offices, hospitality properties and commercial buildings with significant daytime consumption and enough roof area for a properly spaced 36-panel array.
At this power level, the system must be treated as an engineered energy project rather than a universal backup kit. The 15 kW inverter can serve substantial loads, but the battery bank determines how much of that power is available when the grid is absent and for how long. The two-battery set shown on the live page provides approximately 10.4 kWh usable energy and only 7.0 kW maximum published battery power. It cannot be assumed to supply a 15 kW building load from storage.
For this reason, the package is recommended for customers with strong daytime self-consumption and a clearly defined essential-load strategy. Battery capacity and power should be increased only after manufacturer compatibility, required autonomy and the customer's load profile have been confirmed.
Suitable Applications
- Large villas and residential compounds with three-phase supply
- Farms and agricultural businesses
- Offices, workshops and commercial buildings
- Hotels, guesthouses and hospitality facilities
- Sites with high daytime consumption and selected critical-load backup
Why This Package Is Recommended
- The 15.48 kWp array is closely matched to the 15 kW inverter.
- It provides a clear capacity step above the 10 kW range.
- It avoids the 12.90 kWp Small configuration, which underuses the inverter for a standard listing.
- It also avoids the 18.06 kWp Large configuration, which exceeds the current inverter sheet's 18.00 kWp maximum PV input by 60 W.

Important Technical and Installation Notes
- Do not market the published battery set as 15 kW whole-building backup. Its published battery power is substantially lower than the inverter's nominal output.
- Resolve the live two-battery configuration against the current Trio Hybrid K minimum-battery statement. The final capacity, power, price and physical layout may change after confirmation.
- The older 5.8 kWh battery sheet does not explicitly list the 15 kW Trio Hybrid K model in its compatibility row. Obtain current written compatibility confirmation.
- Confirm the correct three-phase smart meter and current-transformer set; the live page lists an Uno meter while current Trio documentation describes a Trio meter / current-transformer arrangement.
- Prepare a detailed phase-by-phase load and motor-starting study before defining the EPS board and required battery bank.
- Confirm battery BMS and communication accessories, cabling, protection, switching, isolation, neutral and earthing design.
- The published mounting set is for a tile roof. Other installation types require separate structural engineering and materials.
- Complete minimum-temperature string-voltage, MPPT-current, cable-loss and connector calculations.
- Confirm utility interconnection, export or zero-export requirements, structural capacity, waterproofing, wind and snow loading, fire access, earthing, lightning and surge protection.
