I tried to register as an installer for Hubble batteries about 3 years ago, tried sending emails, never got a response, tried calling and just never got anywhere with them, so I decided to use other brands for our solar installations, and never had a nice to thing to say about the Hubble brand.

Today I had an inverter repair, which someone had replaced the AGM batteries with a Hubble AM5. The battery had a red light flashing and I needed to make sure all the settings where correct.

I called the support number and within a couple of seconds the call was answered, a technician named Tristan took the call requested a few details about the cloud unit and as I was talking to him he was updating the system.

What an experience, Hubble has gone from the top of the worst companies to deal with, to the top my of my best tech support company list, in one call.
