Sunergy has been installing off-grid and RV solar solutions since 2010.  We only use premium quality inverters and charge controllers from Selectronic and Victron teamed with panels from LG, REC and Suntech and batteries from Powerplus, Victron and GNB Exide.  Why?  Because power is an essential service.

Accreditations:  Sunergy is a Selectronic Accredited System Integrator and Victron Professional and Victron Dealer.  We are proud of these accreditations gained from which are a testament to our knowledge and skills with these world class products.  Our staff include CEC accredited off-grid designers and installers, A-grade electricians.  Sunergy is a Registered Electrical Contractor.

What we do:  Whether it's a caravan, boat, shed, shack, full sized home or even a remote cattle station, we will work with you to design a professional solution to meet your power and budget needs.

Off-Grid Process:

Step 1 - Load Profile:  When considering off-grid, you are in essence building a power station.  In order to get this right, we need a specification of what the power station needs to be capable of.  Our experienced and accredited off-grid designers spend time with you understanding in detail what appliances you are looking to power.  We drill down into the time of day of usage and seasonal variations.  By knowing the time of day, we can design your system to run the appliance from the sun.  If at night, it will need to come from your battery bank or a generator.

The load profile usually takes 1-2 days of our time to get right.  Along the way you'll also get advice from our years of experience on appliance selection and how to do things such hot water (solar may not be the best answer); black water treatment - which solution(s) are off-grid friendly; heating and cooling - a couple of split systems may be more off-grid friendly than a ducted system etc.       

Step 2 - Site Assessment:  Where feasible, we will visit your site to determine locations for equipment, shade, roof sizes etc.  For new builds or remote sites we work from site plans and aerial images.

Step 3 - Design:  Now we know your energy requirements and site details, we develop a system design.  We use specialist design software from the USA, we determine how much solar, battery and generator capacity you need to reliably meet your power and budget requirements.  Where compromises are needed bwtween cost and function, we walk you through the options and provide clear advice as to what that means.  As an example, if your budget means less solar or less battery than "perfect", we calculate what that means in terms of additional generator run time by month and additional fuel cost.  

Step 4 - Build:  We pre-build, configure and program systems in our workshop; this allows quick and easy installation with reduced time onsite.  We also pre-build systems for quick and easy installation by others.  Take a look at some of our standard solutions here.  

Step 5 - Install:  We offer complete installation by our accredited and qualified staff.  Or if you choose, you can purchase a pre-built system and have it installed by others.

Step 6 - Service & Monitoring:  We can include internet monitoring and remote support capability on our systems.  Remote support in particular reduces cost of ownership by saving on call out and travel costs in many cases.  We also offer system servicing and maintenance.

Engagement Process:  Off-grid design takes time and effort from both you and the designer.  Doing an accurate load profile can easily take a day of effort on the designer's part to get right.  As an example, saying "I've got lights, a TV and a fridge" provides nowhere near enough clarity.  What lights?  If they're incandesant, that means anything up to 10x the power required to run LEDs (and those have at least 4 variations in consumption).  What fridge?  A new energy efficient family sized fridge will typically use 1/5th the power of a bar fridge even though the bar fridge is tiny by comparison.  Which TV?  Plasma uses more than LCD which uses more then LED and etc.  Size of your TV is no guide. 

We drill down into this detail and whenever possible, get the actual power consumption for your exact appliance make and model.

Yes, we've seen people who think a load assessment can be pulled out of thin air in a minute or two followed by a "she'll be right mate" wet finger in the air design.  If the load profile is wrong, nothing else can possibly be right.

The reality is getting the load profile right is critical to the difference between happiness and guaranteed future misery.

We get calls all the time from people who have been sold a pup.  Fixing the mess is expensive, more so if no name brand equipment was purchased from eBay.  Ironically fixing the mess means starting with a load profile followed by a design.  Getting it wrong means paying twice.

To avoid this pain, Sunergy charges a design fee of $330 (inc GST).  For this you get a load profile (valued at $880 if we were to charged for our time at normal rates) and two designs each with one iteration (valued at $660).  The total value of this service is $1540.  The service is provided by one of our accredited off-grid designers with 10+ years of experience. 

The design fee is fully refundable if you go ahead with a system from Sunergy.  If you don't go ahead with Sunergy, you have a professionally prepared design and specification you can use to get quotes from others.
