Optimal Management of Home Solar Systems with Batteries

  • Do you have a home solar power plant (PV system) with a battery?
  • Are you disillusioned by fixed tariff buyback rates or the "virtual battery" concept?
    Rising fixed fees and decreasing buyback rates reduce the real return on investment in PV systems.
  • Would you like to try a SPOT tariff without high initial investments in sophisticated devices with uncertain returns?

Try our cloud-based optimal management solution for PV systems

Price:
  • Key advantage: immediate return on investment
  • Initial cost: 0 EUR
  • Regular payment: 5 EUR / month, no commitment, start and stop anytime
Key Features:
  • Savings of approx. 5-10% by switching to SPOT prices + another 5-10% through optimal management
    In recent years, simply using SPOT tariffs has saved an average of 5-10% on electricity prices. Combined with simple smart management, another 5-10% savings can be achieved.
  • Stops exporting to the grid during negative prices
  • Manages battery charging and discharging based on expected household consumption and solar energy production forecast using weather predictions.
    If financially advantageous, the battery can be charged from the grid (in case of very low prices) or discharged into the grid (in case of very high prices).
Basic Requirements:
  • Solar power plant with battery
  • Goodwe inverter, registered on the Goodwe SEMS portal
    If you are monitoring data via your mobile, you are likely already connected to this portal.

In the future, we plan to also support:

Our solution is inspired by the 80/20 rule – to provide 80% of the most important functionality for 20% of the typical costs.
