Buyer Beware
I signed a contract with 1KOMMA5 (Arkana Group) in January 2026 for a 42kWh battery and 15kW hybrid inverter, and paid the 10% deposit to begin the process. Installation was scheduled for the end of April before the Gov subsidies changed.In March I was told in writing that the Energex grid-connection application was underway. When I followed up, it became clear the application had not in fact been submitted at that point. It was lodged in April, as an expedited request, on the same day I raised the prospect of contacting Fair Trading.
In May I received written confirmation that all stock was allocated and ready for my install. On the morning of the scheduled installation, after first being told installers were on the way I was told a critical component was unavailable nationally and the install could not proceed. Two scheduled installation dates passed without the system being installed.
Throughout, I sent multiple follow-up messages, most of which received no reply. As things stand, the system is not installed and I have decided to not proceed with 1KOMMA5.
In my experience, the communication and scheduling fell well short of what I was led to expect at signing. Based on what I’ve described, I can’t recommend them, and I’d encourage anyone considering a deposit to get firm, written commitments on timelines and stock before paying

Original Review on 14-01-2025:
Faultless service from start to finish.
Initial consultation was great, salesperson was polite, knowledgeable and patient. At no stage was there any pressure.Installation went seamlessly. Both of the installers were helpful and worked tirelessly on a really hot day. They were on time and did exactly as promised. Customer service has been very good,
The only slight criticism would be that the wifi reporting has had a couple of glitches.

Hi Karen,Thank you for sharing your experience! We’re so glad you found our team polite, knowledgeable, and professional throughout the process. It’s great to know the installation went smoothly, especially on such a hot day, and we appreciate your kind words about our installers’ hard work.
We also value your feedback about the WiFi reporting and will gladly assist if needed. Your satisfaction means a lot to us. We’re here to help anytime.
10 months later we asked Karen: "Are you happy with the performance of your system so far?"
The system is performing to expectations. Unfortunately I feel that the power companies are letting customers down. Our feed in tariff has changed (not for the better), our consumption charges just keep going up and it seems we are being limited as to how much we feed in. Whilst our sales person did mention that our feed in tariffs may go down, there was no mention of the other charges changing. I certainly feel that the estimated time of our system paying for itself did not allow for any of these known issues.23 May 2025

Excellence
I could not be more impressed by the customer service from start to finish. From Martin, Amanda and the install team.install team were young, but had excellent manners and were so polite and helpful
They explained everything to me. Would have no hesitation in recommending IKOMMA5 for your solar experience.

Hi Debbie,Thank you so much for your feedback. It's great that our team made your solar journey a positive experience. Your recommendation means a lot to us, and we're always here to help with anything else you might need.
Exceptional service, transparency, and a team that genuinely fixes problems. Highly recommend 1KOMMA5°!
The Challenge: Finding the Right Fit Before the 2026 Rebate DropI started my solar journey with a 6.5kW Fronius system already on my roof. I wanted to add a battery to maximize self-sufficiency and secure the best possible rebate before the start of 2026.
Admittedly, I didn't fully understand inverter types or battery sizing at first. I also had a basic interest in Amber Electric and wanted a system that would complement my existing setup. After gathering six different quotes, I quickly realized that navigating this industry is difficult. Only two companies made the cut based on price, equipment quality, and installation timelines.
Why I Chose 1KOMMA5°
I ultimately chose 1KOMMA5° for three main reasons:
1. Premium Hardware: I wanted high-quality, German-engineered equipment.
2. Fair Pricing: The quote was competitive and right in the expected range for premium gear.
3. Speed: They guaranteed they could get the system locked in before the 2026 rebate deadline.
I settled on a new 6kW panel system with a 5kW inverter and a large 40kWh battery, which was supposed to AC-couple alongside my old Fronius system. [1]
Phase 1: Seamless Install & The 5kW Charging Bottleneck
Once the deposit was paid, the administration was effortless. 1KOMMA5° handled all the compliance paperwork and rebates seamlessly. The communication was proactive, and the initial installation team was on time, courteous, neat, and highly efficient.
Both systems fired up and worked together, but I quickly noticed a technical bottleneck. Even though I had two 5kW inverters feeding the property, the battery could only physically charge at a maximum rate of 5kW per hour. With 12.5kW of panels total and a large 40kWh battery, it was going to take far too long to fully charge. I was gutted.
The Turning Point: How 1KOMMA5° Stepped Up
This is where 1KOMMA5° proved they are a cut above the rest. Instead of leaving me stranded, my sales rep, Joel Price, listened to my concerns. We decided the best path forward was to decommission the old inverter and upgrade the new setup to a single 10kW inverter, allowing all panels on the roof to run through it. Joel worked out a very competitive deal for the upgrade that I was incredibly pleased with.
There was a waiting period for the new part, which was completely acceptable because Sarah from the after-care team kept me thoroughly informed and up-to-date the entire time. She was fantastic.
When the day came, the upgrade installation crew was just like the first team: friendly, polite, clean, and fast.
The Verdict: True Self-Sufficiency
My system is now perfectly optimized, charging beautifully, and giving me the exact energy independence I was looking for. I have just signed up to Amber Electric and am letting it gather the month of data it needs to start running my Personal Power Plant optimally.
In an industry that can be incredibly messy to navigate, 1KOMMA5° stood by their work, looked after me when an issue arose, and delivered a top-tier system. I couldn’t be happier with the final outcome and highly recommend them
