Roof Panels

Lonergan and Muhovics can provide a grid-connect roof mounted system to suit your budget and energy needs.  Roof-mounted systems can be installed on homes or sheds, and our custom mounts can help if your roof isn’t facing North.  Small and large scale commercial systems are also available.


What size system do I need?


You can install a solar system to cover part or all of your home energy usage, or earn some money by adding more panels and selling your excess electricity back into the grid.  Retailers pay 6 cents per kWh for the surplus power your solar system exports to the grid.

Solar Battery Storage

Why every house in Australia should have TM5000 Battery system:

  • Saves money in peak energy costs
  • Store net metered solar in batteries to use at peak time
  • Automatic switch over  in Blackouts for protected loads
  • Putting you in control of your energy production and consumption

The tariff management system can utilise all power sources available for the best possible outcome to the householder.


Its smart switch will be programmed to determine the best time to shift power usage. For example, if you do not want to use power at peak time from the grid, the TM5000 will be programmed to draw power at off peak and store power in the battery ready for you to use at peak time. This simple programming will reduce your electricity bill significantly; imagine the possibility of never paying for peak time again!


Another example of this fantastic product is the solar storage capacity.

If you have a solar system that is net metered, you would be well aware that majority of your produced power is going back into the network and you’re receiving either nothing in return or a minimal amount. The TM5000 battery storage unit is able to store the power you’re producing during the day and your battery is ready for your to discharge in the evening when your home, again saving you money on spending at peak time and also using the energy you have created while you’re at work!


Our favourite feature is the blackout protection mode.

In the event of a blackout, your TM5000 disconnects from the grid and will run independently.


Giving you power to the circuits in your house that you have decided to protect. For example, you may want your TV, water pumps, and a few power points to work in a blackout event. You do not need to do anything, the TM5000 will automatically switch itself over to blackout mode and you can carry on without disruption. If your blackout lasts more than a day, your net metered solar system will charge the batteries during the day.


The TM5000 is connected to the cloud giving you realtime information on where your energy is being produced and consumed and the battery capacity. You are able to log in from any computer or smart device. Below is a sample of a graph that can be generated from your TM5000 tariff manager. You are able to get data daily, weekly & Monthly.
