Off-Grid Systems: how do they work?
Electricity from the solar panels powers daytime loads with surplus generation recharging the batteries. Overnight, your house electrical loads are powered by your batteries. If you don’t have enough electricity from either your solar panels or your batteries, your system will automatically turn on the backup generator to supply the shortfall.
There are a couple of approaches to integrate solar;
AC-Coupled solar
DC solar electricity is converted to AC electricity by an inverter, and sent to your household appliances through your switchboard. The battery inverter/charger converts the AC electricity back to DC to charge the battery bank as needed.
DC-coupled solar
DC solar electricity is sent through a regulator or charge controller directly to the battery bank first. The battery inverter/charger then converts this to AC electricity and sends it to your appliances as needed.
Both AC and DC coupled solar have their pros and cons, and you can even include both options in your system design if preferred.
Off-Grid power system
design & load profiling
Our off-grid experts quickly assess your current and future energy needs to design the ideal stand-alone solar system for your property. Every system is carefully tailored for performance, reliability, longevity, and cost-effectiveness.
Energy load profile
Completing an accurate energy load profile is an essential part of correctly designing an off-grid stand-alone solar system ensuring your wise investment and power reliability. The load profile is a list of all your appliances and utilities that require electricity with an estimate of their usage frequency (e.g. how many days per week, and hours per day).
Once we have this information our accredited system designers will review and confirm your energy requirements to progress to our tailored system design phase, accurately recommending appropriate stand-alone power system options and sizes for your needs.

Our Considerations
Stand-Alone System Location
Your equipment location is very important when designing an appropriate off-grid power system. We will discuss what will work best for your site while paying careful attention to system performance, longevity, and compliance.
Solar Array
There are a number of approaches to integrating solar. It must be capable of producing enough electricity (kWh) to replace what is used by your site on any given day – especially on days of poor weather. Our design software considers local weather data, solar panel orientation and inclination to precisely calculate expected solar yields to best determine your ideal solar size.
Off-Grid Batteries
Selecting a battery with the right chemistry, configuration, capacity, and power output is incredibly important to ensure your system’s stability, reliability, and longevity. Our design consultants will consider our range of leading off-grid-compatible batteries to find what will be best for your application.
Inverter/Charger
The inverter/charger needs to be carefully sized to accommodate the continuous and surge power (kW) requirements of your site and appliances. As part of our Energy Load assessment, we will discuss what appliances could operate simultaneously to determine your ideal inverter/charger capacity.
Generator
While our typical off-grid system design approach doesn’t place heavy reliance on backup Generators, they still play an important support role, and careful thought and planning is needed when it comes to their installation and operation. The generator should be installed as close as practical to the stand-alone power system equipment while also considering noise level and adequate safety protection when in operation.

Managed or self-managed batteries – which is best?
The main difference between managed and self-managed lithium batteries is where the BMS is located – either within the battery itself (self-managed), or as a separate piece of hardware (managed). For more detailed info.
Self-Managed Battery
Advantages
Modular and versatile
Inbuilt redundancy, battery module failure bypass
Wide compatibility and can directly replace existing VRLA batteries
Disadvantages
Slower charging
Less accurate SOC monitoring
Managed Battery
Advantages
Fast and accurate charging
Highly accurate SOC monitoring
Disadvantages
Battery fault results in shutdown & power loss
Battery group communication loss results in shutdown & power loss
Reliant on identical battery module firmware
Our consultants are off-grid power system experts and have an in-depth understanding of battery configuration and operation. We will discuss and recommend the most suitable option for your project.
Grid Connection Challenges
Grid connection cost
Determining the cost to connect grid electricity to your new property or new build is an important first step when deciding whether to live on or off-grid.
Often the power lines will appear quite close to your dream block of land but when you begin to chat with your electricity distributor about the cost of getting power connected you can get a nasty (expensive) surprise.
It is not uncommon for a quote to connect to mains power to be in the tens or even hundreds of thousands of dollars. This can make an off-grid power system a much more affordable option upfront and of course, long term.
Off-Grid Energy Australia can assist you in obtaining an accurate cost of connecting electricity to a new property with the electricity distributor for your area. Just contact our friendly team.

1300 334 839System Configuration Options
Here are a few system configuration options available for off-grid system design. Your system designer will be able to explain which design they've recommended for your project, and why.
AC Coupled Solar
Managed Solar
Your solar inverter converts solar energy into usable AC power to run your appliances directly, while using excess energy to charge off-grid batteries via a battery inverter-charger. When solar production is insufficient or unavailable, your batteries supply power, supported by a backup generator if needed. Managed solar inverters are controlled via direct data communication, ensuring a clean and stable system power output.
Intelligent Data Solar Control
Stable, Clean Power Output
Daytime Power Layering
Highly Flexible & Scalable
Unmanaged Solar
Your solar inverter converts solar energy into usable AC power to run your appliances directly, while using excess energy to charge off-grid batteries via a battery inverter-charger. When solar production is insufficient or unavailable, your batteries supply power, supported by a backup generator if needed. Unmanaged solar inverters rely on frequency shifting (Hz regulation) to control solar generation, which can introduce power quality variations and affect the operation of sensitive appliances.
Simple AC Integration
Cost-Effective Design
Frequency-Controlled Solar
Variable Power Quality
DC Coupled Solar
DC Coupled Solar
Your solar panels generate DC electricity, which passes through a Solar Charge Controller to charge your off-grid batteries directly. When your appliances require power, a battery inverter-charger converts this stored DC energy into usable AC power. When solar production is insufficient or unavailable, your batteries supply power, supported by a backup generator if needed. Because the solar charging path goes straight to the battery bank, this configuration offers exceptional efficiency for battery charging and highly stable AC power quality.
Highly Efficient Battery Charging
Stable, Clean Power Output
Excellent Black-Start Capability
Simplified System Regulation
AC/DC Coupled Solar
Your solar energy is split between two paths: a solar inverter converts one portion into usable AC power to run your appliances directly, while a DC charge controller routes the remaining portion to charge your off-grid batteries directly. When solar production is insufficient or unavailable, your batteries supply power, supported by a backup generator if needed. By combining both methods, this configuration captures the best of both worlds, providing maximum daytime power efficiency alongside highly effective battery charging.
Balanced Power Distribution
Maximum System Redundancy
Enhanced Design Flexibility
All-Weather Efficiency
System Configuration Overview Table:
| DC Coupled | AC Coupled (un-managed) | AC Coupled (managed) | |
|---|---|---|---|
| Solar Connection Point | DC side of inverter charger | AC side of inverter charger | AC side of inverter charger |
| Inverter Charger Labouring | Always | Reduced | Reduced |
| Power Layering (solar + battery output) | No | Yes | Yes |
| Solar Integration Ratio | Unlimited | 1:1 | 2:1 |
| Solar Regulation Method | Via EMS or battery bank voltages | Frequency Hz shifting | Data direct |
| System Power Output Quality | Clean & stable | Hz Alteration | Clean & stable |
| Power Quality Output Implications | None | Frequency time based clocks lose accuracy. Sensitive appliances may operate ineffectively or not at all. | None |
