Off grid solar power systems
We design and install off grid solar power systems to provide energy for tiny homes, homes, baches, telecommunication sites, remote farm pumps and more.

How does an off grid system generate power?
Depending on the on-site resources available, generation options include solar PV panels, wind turbines, micro hydro or a combination of these methods. Many off grid systems also have a backup generator.
How does an off grid system work?
The energy generated is stored in a deep cycle battery bank, ready to be used as and when it is needed. Significant advances in technology allow people living in an off grid powered home to go about their day-to-day life without the concern of running out of energy. More details are shown in the diagram below.
Why install an off grid energy system for your home or bach?
An average energy user will likely spend over $25,000 on power in the next 10 years. An off grid solar power system will eliminate this expense, reduce your carbon footprint and add value to your home. It is often cheaper to install an off grid system than pay for a connection to the main grid.
How do I get started?
ESolar can design and size a system to suit your requirements, based on your energy consumption and the renewable generation resources available to you. Our experienced technicians can answer all your questions, give you sound advice, and expertly install the chosen system at the required location.
AC coupled off grid system
Solar PV energy is converted to 230vac by a solar inverter, which is consumed by the household loads. Any excess solar energy is taken by the battery inverter to charge the batteries. The energy stored in the batteries is converted to 230vac by the battery inverter for the household loads when there is limited or no solar energy available. The battery inverter controls the backup generator, requesting it to run and support the off grid system when required.
This system is ideal for general and large off grid systems.
DC coupled off grid system
Solar PV energy is converted to the required battery voltage by a solar controller and charges the batteries. The energy stored in the batteries is converted to 230vac by the battery inverter for the household loads. The battery inverter also controls the backup generator, requesting it to run and support the off grid system as required.
This system is ideal for smaller off grid systems such as bach’s and Tiny Homes.
