What are solar inverters and how do they work?

Solar inverters are the brains of the system that convert direct current (DC) electricity to alternating current (AC) and manage the solar system including charging a battery.

Solar panels produce DC, yet homes and business use AC therefore the inverter forms a critical part of the solar system. Also when installing a DC coupled battery the inverter manages the entire system.

Inverters have evolved a lot over the years from simple grid tie units. There are now different solutions to enable solar installations on small or shaded roofs, using micro-inverters or optimisers.

Hybrid inverters which manage both the solar panels and batteries. Also the latest generation of solar inverters like the Fronius Gen24 even incorporate EV chargers into their management system.

Positive Energy Solutions were amazing to work with. They were the most professional and the cheapest for like for like quotes. They kept in touch with me prior to installation, forwarded by email all the necessary information I needed, managed all the submissions and approvals.
Installation went very smoothly with very friendly, polite and professional installers. They had a problem connecting to the power as it was in an awkward corner but they managed it successfully and it was very neatly done. I’m very happy with the service and the outcome. The app they connected me to is very informative too. Thanks guys, I’m looking forward to reducing my electricity bills!

We installed 15.8kwh Sunpower P7 panel with 15kwh Sigenergy Inverter and 32kwh Sigenergy battery with home gateway and also Sigenergy EV charger to future proof our house and less reliance on grid. So far system work well with 98.5% utilisation. After cosnultation with Maya from the sales team in December 2025 we go ahead and book our install in March 2026. Come installation day. Hiroshi and the team came on time with everything ready with the plan and confirmation with my self to choose the best location of all the gear.

Within less than 2 days everything installed and commissioned smoothly with no mess left behind. With this kind of install basically i am a very happy customer and would highly recommend the company based on my experience. It is not the cheapest system but for me its one of the best in the market for my peace of mind in the long run. Highly Recommended company to trust your solar and battery installation.

We would like to give a big thank you to Louis and the team at Positive Energy Solutions for the excellent Fronius solar system they installed for us.

We were so pleased with the solar panels and hybrid inverter they installed for us when our home was getting built two years ago, that when it came to getting a battery it was a no brainer to go with Positive Energy again.

We had done our own research into which battery to get and Louis’s knowledge and honesty made it an easy decision. We also invested in the whole house back up system. We had the battery installed on 18 November 2025.

The workmanship was excellent and the job was done neatly and with no mess left behind. We have no hesitation in recommending Positive Energy and are so happy with the system we chose.

Update - 24/04/26 we had an issue with our battery charger not connecting to the internet so rang Positive Energy service for assistance. We spoke to Zeb who was very helpful and efficient and resolved our matter really quickly, so thank you and a big shout out to you for brilliant service as well as quality products. We couldn’t be happier with our Positive Energy solar system and service!

The sales and quoting process was really good. The information given was clear and concise with substantial supporting information such that I felt like I was making an informed decision, not receiving a sales pitch. Tom was particularly helpful - taking time to talk through our concerns and questions as well as working with me to ensure that I would financially benefit from the addition of a battery.
Installation was excellent. The installer Ladell and his assistant turned up exactly when they said they would, cracked on and just got it done.

It was a very neat install complete with bollards to protect the battery (it's in my carport).
Customer service was thorough and appropriate. I've had several follow up emails and message confirming payment, the manual and also a snapshot of our power efficiency with the battery online. Also some advice on how to reduce our enerfgy bill further.
Overall this is as good an experience as I have had with renovations and upgrades. Everything was clear, well presented, timely and professional.

OUR OPTIONS

Positive Energy Solar Inverters

Positive Energy Solutions are experts in Solar Inverters, Solar Panels, Solar Batteries, Hot Water and EV Chargers!

Hybrid Inverters

Non-Hybrid Inverters

MLPE Inverters

Hybrid inverters manage both the solar power conversion and charging a battery. Although a battery is not needed for a hybrid inverter to work. They also manage the back up function in a power outage.

Fronius, Sungrow and Huawei are the most popular manufacturers that Positive Energy offer to their customers. All three options are know for their reliability and support. All three options also have a suitable battery to connect with the system.

Hybrid inverters are the best solution for anyone wanting to install a solar battery now or in the future. With the current market trends most customers install a hybrid inverter.

Non-Hybrid inverters are the traditional inverters most people are familiar with, used in both homes and business. They do not have the ability to charge a battery, making them a good option for those customer who do not need or have the space for a battery.

Fronius, SMA, and Sungrow are the most popular manufacturers that Positive Energy offers to their customers. Known for their reliability and good after-sales and support in the Australian market. They have a long history and are highly trusted by our customers.

These inverters are cost effective and an AC coupled battery installation can happen at a later date if needed. Non-Hybrid inverters are great for customers who are able to maximise their day time consumption.

An MLPE (Module-level Power Electronics) inverter works by installing a device on each solar panel. This maximises the production of each solar panel which is especially important on small or shaded roofs. Also it allows for greater system monitoring and has safety benefits. The two main competitors are Enphase and SolarEdge.

Enphase uses microinverters installed on each panel. Whereas SolarEdge uses power optimisers and a central inverter. Enphase can continue generating power even if one panel or microinverter goes down.

SolarEdge is also a hybrid inverter and they have their own battery and EV charging solutions.
