Off Grid Solar System or Stand Alone Solar Power

Off Grid Solar System Solutions

Off Grid Solar System also known as Stand Alone Solar Power is an ideal solution for situations where;

  • Mains power (the network or grid supplied electricity) is too expensive
  • Your location is too remote to get mains power
  • or Both!

This 6kW Off Grid Solar System in Byron Bay cost the same price as connecting to the grid – now they are creating their own electricity!

In fact, an off-grid solar system can be a much more economical solution, even over the short term. A stand alone solar power system is completely separated from mains power and utilises a deep cycle battery bank for storing electricity generated by your solar panels.

Off grid solar system installations are most common in the rural and outback areas of Australia. Often this is because the mains network grid simply isn’t available, or the connection is prohibitively expensive. SAE Group can install stand alone solar power that is completely self-sufficient. This allows you to have the ultimate in self-sufficient power.

Also, while an off grid solar system is an investment, there are generous government renewable energy rebates that may be available.  Contact us today to ensure you don’t miss out on them. These rebates are primarily for people living in remote areas. By accessing the stand alone solar power rebates, you can save thousands on an off grid solar system for a limited time!

Equipment for Off-Grid Solar Systems

Typical off-grid solar systems require the following extra components:

  • Solar Charge Controller – also known as charge regulators or battery regulators. Solar battery chargers limit the rate of current being delivered to the battery bank and protect the batteries from overcharging.
  • Battery Bank – essentially a group of batteries wired together and ensures you have electricity once the sun goes down.
  • DC Disconnect (additional) – used to switch off the current flowing between the battery bank and the off-grid inverter. This is important for maintenance, troubleshooting and protection against electrical fires.
  • Off-Grid Inverter – is essential to convert DC to AC for all household electrical appliances.
  • Backup Generator (optional) – Backup generators typically output AC, which can be sent through the inverter for direct use, or it can be converted into DC for battery storage.

Each off grid solar system should be tailored to meet your specific requirements, in your geographic location. Please find below information on the stand alone solar power products we install.

Our Range of Industry Leading ‘Off-Grid Solar System’ Charge Controllers & Inverters:

Charge Controllers:

A charge controller’s main function is to optimise a PV array’s output as it can fluctuate based on shading and temperature variables found on the average roof.  SAE Group groups’ range of industry-leading charge controllers offer customers reliability and durability while innovative solar harvesting and battery charging algorithms allow customers to maximize system potential and increase renewable energy yield. These improve off grid solar system performance.

Apollo Devices

apollo t80
The Apollo Solar TurboCharger is the most efficient PV battery charge controller available today. The use of Maximum Power Point Tracking (MPPT) makes the entire PV system up to 30% more efficient because it uses all of the output from the PV panels regardless of sunlight, latitude or temperature conditions. All the power circuit components are designed for very low resistance. The amount of power lost in any conductor is proportional to the resistance times the current squared. Since the output current can exceed 75 Amps, we have used special design techniques to keep all the resistances as close to zero as possible. Great for the Off Grid Solar System

Inverters for Off Grid Solar System:

A solar or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a electrical frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

SP PRO Solar Hybrid

selectronic sp proThis versatile grid feed inverter offers the ability to store energy in and use energy from a battery storage system. Whether you wish to install a new solar hybrid system or update your existing renewable energy system to Solar Hybrid, the SP PRO provides the solution.
Being compatible with most forms of renewable energy including DC and AC coupled PV Solar, micro-hydro and wind, the SP PRO can be incorporated into virtually any grid tie system. The SP PRO Solar Hybrid function allows the user to feed virtually all of their renewable energy back into the grid to maximise their net feed-in tariff. The SP PRO minimises the solar power consumed by the user by shifting the user’s day time consumption to a time of low tariff.
An SP PRO solar hybrid system gives you back control of your electricity bill. By appropriately balancing grid power with the available renewable energy and stored battery energy, the SP PRO minimises your electricity bill. With an SP PRO solar hybrid system, you decide how much you pay for your power, not the utility.
