Don’t get this battery

I’ve had so many problems it’s to long to list, and say all the things that haven’t worked out right . If I had know then when I got it ,I would have all these problems , I would’ve not got it ,or returned it after the second problem I had . But it’s like every 6 months something’s gone wrong . The latest is all the batteries inside it have gone dead no charger left at all . So a whole new set has to be put in . And so far nobody can tell me why they went dead . Thank god they are still under warranty but the new ones are only warranty for the length of the unit when new . So only 3 1/2 years . And given the problems I’ve had I ‘m scared now something else will happen again,because another just on single battery in the unit wore out ( or ran flat ) as well . So in less you like having problems every six months, and wasting whole days either on the phone or getting the contractor back out for yet another problem. DON’T GET A SONNEN BATTERY.

Ty Sonnen

Fast , efficient , professional , affordable and came by after hours at four forty five. He was very good. He installed a new outlet outside, so we could run our hot tub. He was friendly professional and willing to finish the job completely. I highly recommend Sonnen Electrical contractors to anybody. We will never use anybody else, but them. Ty thank you for coming to our rescue.We greatly appreciate it

Customer care is terrible

It is the second time i have to get in contact with Sonnen and I must say first time took 5 months to resolve whereas my second time where the whole system blew up for a week have been without a proper response to the way forward. I am afraid of the system which keeps giving wired noices even after it was shut down. Dont buy this system it is not supported properly.

Sonnen CORE is not designed for real life power outages

I have had a Sonnen Core for one year and between the functionality and the support I have ask for it to be removed from my house. When a Power Outage occurs the system comes in to play about 75% of the time the other times I need to manually turn it on. I opened a case and it took 10 months to get them to say there's a failure on a device on the system and it needed to be replaced and this is after needed to call my lawyers and everything. This is un acceptable support. I do not recommend the battery or their support to anyone.

Great battery with Connected Solutions Support

A well priced battery that works with the connected solutions programs in MA and RI. I work as an installer so my experience is more from that point of view. However, I have also heard from customers that the battery has worked as expected during power outages. For an AC battery, this is the best priced I have found so far that works for small to medium sized houses. Support used to be pretty bad, but after communicating to a couple of higher ups the support has been great the last several months.

Terrible Customer Service

Our battery has not performed as specified in two of the three power outages we had since we had it installed. Customer service won’t respond to installer or to me. Repeated calls and mails - nothing. It is a Sonnen Core.
