The power electronics are based on silicon carbide (SiC) semiconductors and an efficient passive cooling system. According to E3/DC, this minimises conversion losses and delivers high efficiency with a low noise level of no more than 30 decibels.
The battery system offers a C-rate of 1, allowing batteries with capacities of up to 11.8 kilowatt-hours to be fully charged or discharged within one hour. Depending on the configuration, the charging power reaches up to twelve kilowatts, matching the AC output of the inverter. Battery capacity can be retrofitted within five years. Up to five modules can be combined in a single battery tower, and two towers can be connected in parallel, resulting in a maximum usable capacity of around 30 kilowatt-hours.
The One inverter is equipped with three independent MPP trackers, enabling flexible planning of PV systems up to 18 kilowatts – even for installations with different roof orientations or multiple roof areas. Integrated energy management supports efficient use of dynamic electricity tariffs and provides free updates and feature enhancements throughout the system’s lifetime. The One home power plant is also prepared for bidirectional charging. (nhp)
