We opted for a PV system from Energieversum. The advice from Mr. Tim Reimann was very comprehensive. As an engineer, I was impressed by the technical data.
We installed a system from AlphaESS with 32 panels, each with an output of 400 W = 12.8 KW. Storage capacity 2 x 7.8 Kwh and a wallbox. When buying a PV system, you should pay attention to the following:
- Max. Charging/final charging power for the SMILE Hi 10 storage system is 10,000 W for other systems 2,500 W. What does this mean? If several consumers are connected to the grid at the same time and an electric car is also being charged, the required power can quickly exceed 2,500 W! The more power required (> 2,500 W) is then drawn from the grid and paid for dearly, even when the storage system is full!
- Compare warranty conditions carefully: The charging cycles of an energy storage system should be unlimited. What use is a 20-year warranty, for example, if the maximum permissible charging cycles reduce the warranty period to 6 years?
- Should your PV system also work if the grid operator has a power failure? Many systems will then no longer work. If you still want electricity in your home, the PV system should be prepared for this.
These are just a few points that should definitely be taken into account. It is worth comparing, I am convinced of the AlphaESS system and Energieversum. I would like to thank Mr. Tim Reimann once again for his excellent advice!
