As Australians experience the pain of energy price fluctuations and growing concerns over grid reliability, hybrid inverters and storage solutions are emerging as a compelling alternative.
Solplanet’s T2/T3 inverters and G2 batteries promise efficiency and independence.
The Solplanet T2/T3 series hybrid inverters, combined with Solplanet G2 energy storage units, create a modern system that offers extensive scalability to suit user expectations.
These inverters provide up to 48 kilowatts (kW) of reserve power and 81.92 kilowatts-hour (kWh) of energy storage capacity.
These inverters are the second generation of Solplanet products, representing the culmination of the company’s long history.
A key feature of these inverters is their easy and quick installation, with simple plug-and-play configuration.
Notably, they use SunClix DC connectors manufactured by Phoenix Contact.
These connectors are designed for seamless installation without specialised tools. All wiring connected to the T2/T3 inverter is based on connectors that can be easily disconnected if required.
The second-generation inverters come in a wide power range, from 5kW for the T2 series to 12kW for the T2 and T3 series.
The key difference between the T2 and T3 is the number of independent maximum power point tracking (MPPT) inputs for connecting photovoltaic module circuits.
The T2 has two MPPT inputs, while the T3 features three.
The additional MPPT input in the T3 series expands system design possibilities, particularly for photovoltaic installations on multi-slope roofs.
Users can connect up to four inverters in parallel. Once configured, they function as a single system, combining their power output.
The system operates in both on-grid and off-grid modes, supplying power during mains failures.
It supports full three-phase operation, with a switchover time of less than 10 milliseconds.
This ensures seamless operation of household electrical appliances – oven clocks, for example, remain unaffected.
The system does not require additional automatic transfer switches (ATS).
There are multiple energy storage management modes.
Users can choose to charge the battery exclusively from solar power, from solar and the grid at specific hours, or manage discharge to prioritise self-consumption or export energy to the grid.
This is particularly relevant as dynamic tariffs are set to launch mid-year.
These tariffs could allow users to charge batteries with low-cost solar or off-peak grid energy and sell stored energy during peak pricing periods in the evening.
The entire system is managed via a smartphone or computer application.
The app is intuitive and provides extensive analytics, offering insights into household energy consumption.
By reviewing energy usage patterns in the app, users can adjust habits to reduce costs.
Solplanet has also introduced its second-generation energy storage system, the Ai-HB G2 series.
A defining feature of this system is its modular design, which simplifies installation and allows for later expansion.
A single unit consists of a battery management system (BMS) module and a minimum of three battery modules, each with a capacity of 2.56kWh.
The system can be expanded to a maximum of eight modules, reaching 20.48kWh of capacity.
Up to four units can be connected in parallel, providing a maximum of 81.92kWh. The average household uses approximately 20kWh per day.
When paired with T2/T3 series inverters, G2 energy storage units form a complete power supply system for households and small businesses.
They enhance energy independence and provide security in case of grid failures.
The system also addresses issues related to unstable grid voltage, which can affect properties located far from or too close to transformer stations. Solplanet provides full support in Australia.
The company’s hotline offers information on installation, commissioning, and system use.
There are also regular technical training sessions for installers to ensure safe and correct installation of Solplanet solutions. In March alone, 18 such sessions were conducted.
Solplanet continues to develop new functions and enhance system performance. Users receive these upgrades for free via remote software updates performed by technical support.
A hybrid inverter and energy storage system offer significant benefits. It is far from being just an unnecessary gadget.
