If you think it’s expensive to hire a professional, wait until you hire an amateur.
No response
I have contacted Bau-Tech four times now via both of their mail address in English and German and got no response at all , they seemed like a good company and I would have purchased from them for the next order , but this failure to even respond is worrying and unprofessional.
They were happy to accept the money , no interest in after-sales support.
German Quality.
I replaced the broken battery connector today , it is obvious that Matthias Runne wasn’t going to live up to his promises and get a replacement sorted , he dishonours himself further.
German Quality
When we expressed disappointment in Matthias Runne’s “German Quality” workmanship we were not expecting an aggressive and potentially violent confrontation.
Underestimated
It has been almost a week since Matthias Runne abandoned us and our solar kit installation after we gave him the final payment.
Continuing the project myself , I have started switching the house from mains electricity to the inverter only to find it too is not up to the task.
After (supposedly) 100s of hours of research and phone calls , Matthias Runne’s recommendation of a 3000w inverter is totally inadequate.
Strange that a ‘German Quality’ Solar Installer doing a proper site survey should have made such a fundamental error.
In 2015 I measured the electrical power usage of most of the equipment in our house and gave him these details during the site survey.
For example , our washing machine uses 2500w peak and our microwave uses 1150w.
Both of these devices cause the 3000w inverter to reset and are unusable.
In his incompetence he has also chosen a high frequency inverter where a low frequency one would suit our equipment better.
So much for the 100s of hours Matthias Runne supposedly spent calculating and specifying the solar kit we needed , when I powered on the washing machine for the first time the whole system died.
