Opposite experiences between solar and battery installation

I previously had a great experience with Sunsent for a solar installation, but my experience with their battery installation was very disappointing. From signing the contract to receiving final approval to use the batteries, the process took over six months. Approval from the city alone took more than a month. Despite being assured multiple times that Sunsent was in weekly contact with the city regarding permitting, this turned out not to be true. It wasn’t until I contacted the city directly that I learned no one from Sunsent had acknowledged the city's response about an electrician to sign off on the installation plans, which contributed to the prolonged delay. Even when I shared this information with Sunsent, the response was defensive lies that they had been in weekly communication with no offer to resolve the problem still. It wasn't until I sent a formal termination of contract letter did I receive a solution. After city approval was finally received, installation was still delayed with very poor communication about scheduling and timelines. The installation was estimated to take less than a day but ultimately took nearly two full days. The initial city inspection failed due to loose wiring, requiring yet another appointment to correct the issue. Communication throughout the entire process was consistently poor. Technicians repeatedly said that “someone from the office will contact you,” but no one ever did. Each time, I had to reach out myself after a week or more of radio silence to get the next steps scheduled. This pattern occurred at every stage of the project. After installation, I asked for guidance on setting up the batteries to meet my needs and never received a response. After hours of self-study, reading the manual and online forums, I was eventually able to get the batteries turned on and presumably configured appropriately on my own. Delays, lack of follow-through, missed expectations, and quality issues made this a very frustrating experience. Based on my battery installation experience, I cannot recommend Sunsent unless their project management, communication, and post-installation support significantly improve.
