Product Overview
The Infini Solar WP (Waterproof) 15kW is the outdoor-rated variant of the Infini Solar three-phase hybrid platform. The IP65 housing allows the inverter to be installed in locations where a conventional indoor unit would require a separate weatherproof enclosure: directly on an exterior wall, inside a dusty industrial building, or in an agricultural plant room with no climate control.
The -25°C to +60°C operating range covers the full UK climate comfortably and extends to cold storage and industrial environments. The 150% unbalanced load support allows the inverter to manage three-phase supplies where loads are not evenly distributed across phases, which is common in commercial and agricultural buildings.
The dual output configuration can be set to accept a generator input on one output port, enabling automatic changeover between solar, battery, grid, and generator sources.

Installation and Safety Notes
Must be designed and installed by a qualified electrician or solar installer. Three-phase grid connection requires G99 application and DNO approval. Even with IP65 protection, the inverter must not be installed in direct sunlight without shading, as excessive ambient temperature will reduce output. Battery and generator connections must be made by a qualified electrician. Do not attempt DIY installation of three-phase hybrid inverter systems.
