In Belgium, they introduced a new capacity tariff this year. To avoid an increase in the electricity bill, it is important to ensure that the 15-minute average consumption remains below 2500W.
One simple way to achieve this is by using ESS peak shaving and limiting the input current to around 11A. However, I have encountered an issue with this approach. When the batteries are full, I have noticed that the feed-in current is also limited to 11A. Consequently, the MPPTs throttle down to ensure that the feed-in current stays within the 11A limit.
This behavior was observed in my setup, which includes the following components:
- 2 x Multiplus II 5000/70 units in parallel
- 1 x Cerbo Gx 3.00
- 2 x MPPT 150/45 units
- PV system with a total capacity of 6400W
In my opinion, if the feed-in limiting option in the ESS settings is turned off, there should be no throttling down. I would like to know if this is something that can be resolved.
Thank you for your assistance!
