It manages solar panels, battery, grid, and backup power in a single unit. As part of the Deye AI-W16 All-in-One system, it can be combined with AI-W16 battery modules to form a compact, unified energy storage system.<\/p>\n<p dir=\"ltr\"><strong>Why choose this inverter?<\/strong><\/p>\n<ul dir=\"ltr\">\n<li><strong>12 kW three-phase power.<\/strong> Provides balanced supply to three-phase household loads, heat pumps, and EV chargers.<\/li>\n<li><strong>200% PV oversizing.<\/strong> Supports up to 24 kW of solar panels, with a maximum PV input power of 19.2 kW. This means more energy production on cloudy days and in the morning and evening.<\/li>\n<li><strong>Strong battery connection.<\/strong> Charges and discharges the 48 V LiFePO4 battery at up to 240 A, allowing full use of the 12 kW battery capacity.<\/li>\n<li><strong>Reliable backup power.<\/strong> Switches seamlessly to backup operation during outages and delivers twice the rated power for 10 seconds, allowing devices with high starting currents to start up.<\/li>\n<li><strong>Outdoor installation ready.<\/strong> IP66-rated, suitable for outdoor placement.<\/li>\n<li><strong>Expandable power.<\/strong> Up to 3 inverters can be connected in parallel, reaching up to 60 kW of three-phase power.<\/li>\n<li><strong>Smart energy management.<\/strong> With 6 adjustable time windows, the system charges during low-rate periods and supplies loads during peak hours. It can manage a diesel generator, an AC-coupled existing solar inverter, and smart loads. LoRa-based wireless feed-in limitation is also supported without internet access, using the Deye Wireless CT.<\/li>\n<li><strong>Remote monitoring.<\/strong> The Deye Cloud app displays real-time data, supports dynamic tariffs, and the AI-powered Deye Copilot assists with scheduling.<\/li>\n<li><strong>Safety.<\/strong> Built-in DC switch, anti-islanding protection, insulation resistance and residual current monitoring, and Type II surge protection on both the DC and AC sides. AFCI arc-fault protection available as an option.<\/li>\n<\/ul>\n<p dir=\"ltr\"><strong>Who is it recommended for?<\/strong><\/p>\n<p dir=\"ltr\">For three-phase connected homes seeking battery storage and outage protection for a 10\u201320 kWp solar system. For full battery power output, we recommend 2 AI-W16 modules (32 kWh).<\/p>\n<p dir=\"ltr\"><strong>Key technical specifications<\/strong><\/p>\n<div dir=\"ltr\">\n<table>\n<thead>\n<tr>\n<th scope=\"col\"><\/th>\n<th scope=\"col\"><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Rated AC power<\/td>\n<td>12,000 W (max. 13,200 VA)<\/td>\n<\/tr>\n<tr>\n<td>Grid<\/td>\n<td>230\/400 V, 3L+N+PE, 50 Hz<\/td>\n<\/tr>\n<tr>\n<td>Rated \/ max.
