The systems are designed to maximize solar self-consumption by routing DC power directly to the unit’s internal DC bus, avoiding losses and extra costs from AC/DC conversions. They offer a 6–34.15 kW capacity range with COP up to 4.70,
GoodHeat, a unit of Chinese inverter and battery manufacturer GoodWe, has introduced a new line of air-to-water heat pumps for residential use at the SNEC 2026 trade show in Shanghai, China, last week.
The full DC inverter system is esigned to optimize solar self-consumption. By routing DC power straight to the unit’s internal DC bus, it eliminates the efficiency losses and hardware costs associated with traditional dual AC/DC conversions, the manufactuer said in a statement.
The product lineup covers a versatile capacity range from 6 kW to 34.15 kW to suit different property sizes. Models from 6 kW to 14 kW are designed for standard residential use, offering high efficiency as single-phase units, with the 6 kW version reaching a coefficient of performance (COP) of 4.70. Larger models from 16 kW to 34 kW are intended for bigger residential or light commercial applications and achieve a COP of 4.55.
The smallest model has dimensions of 1,170 mm × 462 mm × 855 mm and weighs up to 132 kg, while the largest variant has a size of 1,220 mm × 452 mm × 1,657 mm and a weight of up to 212 kg.
