OG Trade Services

A huge thank you to OG Trade for a fantastic battery installation experience! They recently completed an additional 20kWh battery installation with expertise and efficiency. What truly impressed me was their clever use of the limited available space, resulting in a setup that looks seamless, high-end, and highly professional. I highly recommend OG Trade for their exceptional workmanship and smart, practical solutions.

A huge thank you to the team at OG Trade Services for the outstanding installation of our solar panels! From start to finish, their service was exceptional. They were highly professional, knowledgeable, and the final result is fantastic. We couldn't be happier and would definitely recommend them to anyone.

We recently had our solar panels and batteries installed by OG Trade Services, and we couldn’t be happier with the experience. Heisan Quinten was excellent to deal with — very professional, transparent, and made sure we got a great deal that suited our needs. The installation was smooth, the team was punctual and efficient, and everything was explained clearly. Our system is running perfectly, and we’re already seeing the benefits. Highly recommend OG Trade Services and Heisan for anyone looking for a reliable solar and battery solution!

This is by far one of the worst and most frustrating experiences I’ve ever had with any company. I paid a deposit to Haisen for a solar system with batteries. He confidently told me an inspection wasn’t necessary, even when I offered one. Yet when his team finally came out before installation, they told me the roof was too steep and the job couldn’t be done. So why take my money in the first place? After the failed inspection, I repeatedly asked for my deposit back. He ignored every message. No response. No refund. Only after I posted this review did he finally bother to call — not to apologise, but to pressure me into removing the review in exchange for my own money. When I refused to give him a five-star rating, he suddenly changed his story and claimed my entire deposit was actually a $200 “administration fee.” This was never disclosed, never agreed to, and frankly feels like an excuse to keep my money. People deserve to know what they’re dealing with. My experience with this business: zero transparency, poor communication, and a complete lack of professionalism. I would strongly warn others to think twice before signing anything or handing over a cent.

I had a fantastic experience with OG Trade Service for my solar and battery installation. The quality of their work is excellent, and everything was completed to a very high standard. What impressed me most was their commitment to getting the job done on time—they went above and beyond to ensure there were no delays with the progress of my house build. The team was professional, reliable, and genuinely cared about delivering a great outcome. Highly recommend OG Trade Service for anyone looking for solar and battery solutions!

I highly recommend Haisen and his friendly team at O G Trade Klemzig who installed a 5kw Inverter and 2*10.1kw Neovolt batteries in my garage with a designer bollard included. They did a great deal on price that could not be beaten. The batteries were installed in under 3 hours and worked immediately being powered by my existing solar system I am one very happy off gridder 😃

Haisen + Jay what a team. Installed 3phase hybrid inverter and six batteries in one afternoo for an unbeatable priçe The system was running perfectly the next day with Amber smart shift. I have to add i love the diagram in the neovolt app showing the direction of energy it's working well with the Amber's smartshift

Friendly, very knowledgeable, competitive price, installed 2x 10kw 3phase inverter 28kwh batteries, and a ups circuit. Satisfied customer.

Haisen and his team recently installed a 50.5kWh battery system at my home. Friendly service from quotation to installation and competitive pricing. The installation team communicated well throughout and were responsive to my questions and queries. The battery is up and running and I haven't drawn extra from the grid since, very happy. I highly recommend Haisen and OG Trade team for a battery installation.

I found this company through a friend who highly recommended them for solar battery installation. I contacted them and received a prompt response. They clearly explained the different options and were very knowledgeable. The service was excellent from start to finish. During the installation, they took the time to explain everything thoroughly. I originally thought my old solar system was broken and asked them to help remove it to make space for the new batteries. However, they inspected it and discovered that the system itself was still working — only the machine was faulty. They even offered to remove it for free. While checking my solar setup, they also noticed a crack and gave me helpful advice on what to do. Without their professional assistance and honest service, I probably would have spent more than necessary. I highly recommend this team for their expertise, integrity, and great service.
