A company spokesperson informed pv magazine that the PowerHarvester, a lithium iron phosphate storage system, is available in six power classes with capacities ranging from 7.7 kWh to 27.2 kWh. The system’s starting price is €8,900 ($10,233), which includes installation, the Heartbeat AI energy manager, and a smart meter to optimize benefits from variable electricity prices.
To use the Energy Trader function, customers must pay a monthly software fee of €9.90 and subscribe to 1Komma5°’s “Dynamic Pulse” electricity tariff. CEO Philipp Schröder explained: “The PowerHarvester, controlled by Heartbeat AI, automatically purchases electricity whenever the price on the electricity exchange is particularly low and later makes the electricity available to the customer or sells it when the price is particularly high.”
According to 1Komma5°, data from nearly 50,000 energy systems shows that electricity costs can be reduced by up to 50%. For households with annual electricity consumption exceeding 10,000 kWh—above average for private homes—the system could pay for itself within six years. This level of consumption is common in homes with heat pumps, electric vehicles, or other high-energy devices. The company noted that future grid charge flexibility could further enhance savings.
The PowerHarvester also addresses a previous limitation by offering compatibility with all inverters, charging systems, and heat pumps through its advanced energy management system and digital measurement technology. This improves its versatility compared to earlier versions, which worked only with specific manufacturers.
Chief Product Officer Jannik Schall stated: “The real problem with the energy transition is not cheaply produced electricity from wind and solar, but rather a rigid grid without smart meters and without sufficient storage capacity.” He suggested that promoting full grid flexibility, expanding smart meter use, and exempting small storage systems from grid fees would improve economic efficiency.
The launch of the PowerHarvester reflects 1Komma5°’s efforts to make energy storage accessible and cost-effective for households, supporting greater adoption of renewable energy solutions.
