Grid optimized chargeNew version now online!

We want to constantly improve our products for the users of our electricity storage systems. That is why we have also further optimised the FEMS app "Grid-serving charging". The introduction of the minimum charging power ensures an even more efficient charging process.

The optimised FEMS app "Grid-serving charging" reduces the risk of derating and increases battery health.

To optimise the charging behaviour throughout the day, the app uses a forecast of local generation and consumption. If the generated power reaches the feed-in limit of the grid operator, the charging adapts in such a way that the PV system is prevented from being regulated and is charged with "free" energy.
