I signed a contract for a PV system with 10 KWp and a 10.5 KW battery at the beginning of June 2023. The advice I received on the phone and via video chat could definitely be described as competent.
After about 6 weeks, the Madule was installed. Hooray!
However, the installation of the batteries and the electrical connection took some time. First a company from Berlin contacted me and arranged an installation date, but nobody turned up. After asking on the phone, the person at the other end of the line didn't know what I was talking about. After time-consuming queries, a new appointment was made, but again nobody turned up.
After complaining to Solarhyp, another company from the local area was commissioned to carry out the installation of the batteries and the electrical system. Unfortunately, it was discovered at the end of the day that a connection had probably not been plugged in correctly when the modules were installed on the roof.
After repeated inquiries, the installation company came back twice more until the fault was found.
Back to the electrician, another 2 weeks of waiting.
On November 15, the system was actually completed and is generating its own electricity. However, it has not yet been fed into the grid.
According to the contract According to the contract, it was promised that if the system was not completed within 8 weeks, the electricity bill would be paid. I am still waiting for the credit note.
In December, when there was snow on the roof, I realized that the arrangement of the modules in the app cannot match the position of the modules on the roof. I opened a ticket and nothing happened.
In January, the system reports in the app that there is no communication with the batteries, ticket opened, nothing happens except terse replies asking for patience. Have now had 7 weeks of patience. Calls to the support hotline are answered with friendly promises, but nothing happens.
The system has not yet been accepted by the metering point operator either. At the moment I cannot say who is responsible for this. Queries to Solarhyp about the registration date and registration number could not be answered. The metering point operator in turn needs the registration number.
I still think Enphase's system with the micro inverters is excellent. There may be better providers for the installation.
