Features

Integrated all-in-one design

Integrated all-in-one design

Erfassung, Speicherung und Nutzung sind in einem einzigen, kompakten Gerät vereint. Der integrierte Mikro-Wechselrichter wandelt Solarstrom direkt in nutzbaren Wechselstrom um. Das spart Platz, macht separate Komponenten überflüssig und vereinfacht die Installation drastisch.

Highly efficient energy generation

Highly efficient energy generation

Four independent MPPT channels and 2.4 kW input power maximize energy consumption. Minimized losses ensure peak efficiency and significantly more electricity for your own use.

Intelligent cost management

Intelligent cost management

The integrated 1.5 kW inverter uses dynamic electricity tariffs to your advantage. It automatically charges at low or negative prices, thus sustainably reducing your costs.

Disclaimer

The projected annual electricity cost savings of up to €1,104 and a CO₂ reduction of approx. 2,412 kg are model-based estimates derived from the following parameters and calculation models:

Basis for Electricity Generation
Based on data from the MARSTEK EMS platform, a 1,000 Wp solar module in Southern Europe generates up to 1,160 kWh annually. With a maximum PV input power of 2,400 Wp for this product, a theoretical generation of 2,784 kWh/year results. The calculated annual storage capacity amounts to 3,825.2 kWh (10.48 kWh capacity × 365 days).

Calculation Assumptions

  • Self-consumption rate: 85%
  • Average electricity price: €0.40/kWh
  • AI-optimized price advantage: €0.132/kWh (difference between peak and off-peak tariffs)
  • CO₂ reduction factor: 0.997 kg CO₂ per 1 kWh of solar power

Calculation Details

  1. Annual Savings: Sum of self-consumption (2,784 kWh × 85% × €0.40) and AI-optimized charging management ((3,825.2 kWh − 2,366.4 kWh) × €0.132) ≈ €1,104.
  2. CO₂ Footprint: 2,784 kWh × 85% × 0.997 ≈ 2,412 kg.

Note: Actual savings may vary depending on regional solar radiation, local electricity prices, individual consumption behavior, and the orientation of the devices.

Legal Notices (Germany)

To benefit from the simplified regulations for plug-in generation systems according to § 8 para. 5a EEG, the following limits apply:

  • The total installed PV capacity must not exceed 2,000 Wp.
  • The inverter apparent power must be ≤ 800 VA.

If your system exceeds these limits, the regular requirements of the grid operator apply. This may include, among other things, extended registration, a meter modification, or formal approval procedures. Please inform yourself about the locally applicable regulations before installation.

Registration & Installation:
Plug & Play solar systems can generally be installed and connected independently in Germany. Registration in the Market Master Data Register (MaStR) is legally mandatory (www.marktstammdatenregister.de). Registration with the grid operator has been significantly simplified or partially automated by Solar Package I.
