Residential Grid Connect Systems


Grid connect solar power systems use an inverter to supply renewable energy directly to your home. If your household is receiving more energy than needed, the grid connect system will feed the surplus energy back in to the main grid. If there isn’t enough sunlight to power your property, you can automatically draw electricity from the main grid to cover the energy loads. Please keep in mind that during a power outage, grid connect systems automatically shut down to protect utility workers from electrocution. A grid connect system consists of:

  • Solar panels
  • One or more solar inverter
  • Monitor system
  • Safety breakers, fuses & disconnects

How does solar power work?
Firstly, the solar panels absorb sunlight which is then converted to energy, this is then fed into your inverter. A solar inverter will then convert the energy into electricity (240V) that’s used to power your home. The excess power that’s generated is then fed back into the main grid.

A common mistake some people make is thinking that because the sun is still shining and the energy that is being converter to power is still available to use in the home if the grid fails during the day.

Unfortunately this is not able to happen due to a built in safety feature in every approved grid connected inverter. The inverter will shut down and sometimes displays an error saying missing grid.

This safety feature is called AS4777. Every inverter that is approved to be installed in Australia has to be tested to make sure it will switch off at a set amount of time. This safety setting is to stop your inverter pushing power back into the grid and risking the death of anyone who is working servicing the power lines. It is very important to make sure that when upgrading or replacing a faulty inverter that it has the AS477 certification as the penalties and dangers for using uncertified equipment are extremely high.

Electricity bills are on the rise—investing in solar energy has never been more affordable!

Hybrid Battery Systems

How to choose the best hybrid battery system for your needs

Installing a hybrid battery system is an optional source of backup energy that is used to reduce your energy bills for your night time consumption and it also comes in handy if you have constant  power outages.

It is very important to note that a hybrid battery system is very different from a traditional off grid system. Some hybrid system are designed to only cover a certain amount of loads and are usually wired into a nominated circuit in your meter box.

The Tesla Powerwall 2 is more flexible and is able to cover loads with a surge rating of 7kW.

I is very important to work with a company that has knowledge in offgrid and can help you understand the limitations for hybrid system.

At Mega Watt Power, we’re proud to be a certified installer of the Tesla solar battery system. Boasting a sleek design and innovative engineering, the Tesla Powerwall 2 will minimise your reliance on the main grid by using energy that’s been stored into the batteries from your solar power system.

The Tesla Powerwall 2 is capable of detecting grid outages and will automatically switch over to supplying you with the energy that has been stored in the Lithium batteries, even if you have a mains power outage during the day.

It is important to make sure that your solar array is an adequate size when installing a hybrid battery system.

A solar hybrid battery system distributes the energy from the solar array in the following way.

First the energy loads that are operating in your home during the day will be supplied by the solar energy first.

Secondly any excess energy will go to the batteries to keep them fully charged and to be stored for later use.

Then any excess once the batteries are fully charged will be exported to the grid.

Many of the retail energy providers are keen for you to keep using their energy for obvious reason.

We are currently seeing AGL and Origin Energy offer a .20 cents feed-in tariff for any exported energy from a solar power system.

While these incentives are being offered it is a good idea to make sure you do your payback calculations before outlying an money for a hybrid solar power system.

We love selling an installing hybrid systems but we get greater pleasure from proving the best money saving energy solution that will suit you and your family.

Government rebates

The Clean Energy Regulator 

Small-scale technology certificates STC;s are used to claim for all systems under 100kW

Large-scale generation LCGs are used to claim for systems above 100kW and the formula used to calculate is different from the STCs.

Off-Grid Solar Power Systems

24 x 2SG1000 SunGel Batteries

How to choose the correct size system

Off-grid solar systems are mainly  installed to homes that are not connected to the main grid at all which is more common for remote or regional areas.

We are being asked more an more from people who are connected to the grid to also provide quotes for these systems.

Off Grid solar power systems are sized, designed and use different components than what is being used in a standard grid connected hybrid solar power system.

For a costume to transition from mains power to full off grid it requires a greater understanding of the current energy loads used.

Not all companies have the expertise or understand how to design a full off grid system if the customer wants to transition from mains power to full off grid.

Our experienced team of designers who have over 30 years experience will design a system that will suit the usable kWhours required for your electricity loads.

Our team can design a very small systems for a cabin or shed to very large systems for commercial use.

We have also designed a pre build system which is tested in our workshop under load before we install on site which makes installation quick. Our cabinets are designed to enhance the life expectancy of the electronics and equipment and easy maintenance for the customer

Off-grid solar systems consist of:

  • Solar panels
  • Solar batteries
  • One or more inverters
  • Generator 
  • Charge controller or an apporved Grid Connected Inverter
  • Safety breakers, fuses and disconnects
  • Energy monitor
  • Backup service and support

Batteries for off grid systems are still very expensive. It is vital that the owner of the system understands the limitations and is able to adjust their energy consumption to suit the the usable kWhours that have been are available from the batteries.

Solar Water Pumping

Solar Water Pumping for farms

Solar water pumping has come a long way over the past years.

Now that solar panels have reduced in price , installing solar water pumping has become more cost effective. 

Our systems are designed more for agricultural application on a larger scale than the small backyard water feature or fountain.

Our solar pumping experts will be able to assist in helping to design the best pumping system to suit your water needs
