Inverter Upgrade and Battery Installation

The entire process from quoting to installation was very well managed. I felt I was indeed dealing with experts who importantly took the time to understand my requirements. I was kept informed at all stages of the process. Thank you for such professionalism.

We were kept updated on the whole installation process

We were kept updated on the whole installation process.
The guys Andrew , Tom and others were helpful and polite. The follow up service has also been great with Jake calling to make sure we understood the app functions and if we needed any further assistance.

Great Experience with 1komma5!

I have recently had a battery installed with 1komma5. I had excellent service from both the specialist Phil who first came out, Jake who provided all my install updates and the team that installed the battery. The installation was really clean and they left the garage spotless afterwards.

Seemless and stress free

From start to installation the whole process to painless and stress free. They kept me informed about every step of the process either through text or email. All of my thousands of questions were answered promptly and without judgement. Installation day went so incredibly smoothly I didn't even notice they were installing solar into my roof. Everyone i interacted with either by phone or in person were so incredible polite and helpful. I cannot recommend this company enough.

Professional install and slick app

We got a battery installed with 1Komma5. The sales team (Cameron and Lisa) were very patient while we experimented with a range of configurations and prices, Daniel the installer and his team were very professional and did a really neat job (and helped move things around to get the right circuits on the automated backup), and when there was a fault Aaron was extremely helpful in getting the tech straight back out to get it resolved. Very happy with the app and the experience so far.

From the first phone call and home…

From the first phone call and home visit,sign up, to installation we were kept informed about every step of the process either by text or email. Any questions were answered promptly and accurately. Installation day went without a hitch. Once installed I was shown how to use the online app and the shut down process. The installer waspolite and informative. 10/10.
All persons dealt with were super professional.
Special thanks to Jake White for organising everything.👍

From the initial enquiry/pricing and…

From the initial enquiry/pricing and discussion with Nicole to the final installation it all went smoothly. A couple of follow up emails required at times but hey the company is doing a lot of work.

Nicole was fantastic in keeping me abreast of where things were at.

The informative presentation video by the CEO I thought was excellent (simple but with all required information to base your decision.

Jamie (pretty sure name is correct) installed on site and was very professional and once again kept me informed.

Torston Jamie's immediate boss you could tell was across the whole installation even though he was obviously running multiple installs.

Basically I KOMMA5degrees run the whole operation as a well oiled machine through each and every step.

Yep I will be recommending them. I've been in the construction industry for over 40 years (management) so I know when I see a good company.

Cheers

Brilliant end to end.
From quote to acceptance to install it was a breeze to deal with 1Komma5.
