ARE SOLAR PANELS MEETING YOUR NEEDS?

With the rising costs of electricity, many people invested in solar energy equipment. Initially, the rate you received for exporting excess electricity (your Solar Feed-in Tariff) was high, which made your investment worthwhile. However in recent times, the Solar Feed-in Tariffs have been significantly reduced. For example, the PFiT scheme in Victoria ended in 2024 and the minimum feed-in tariff was set at 3.3 cents per kilowatt-hour, resulting in a dramatic rise in electricity costs for solar users. Frustratingly, this defeats the purpose of investing in solar in the first place!

To better understand this situation, it is helpful to refer to a typical daily solar generation curve vs load curve diagram (see below).

Are solar panels meeting your needs?

THE BAD NEWS

You are paying 25-45c/kWh for electricity that you are buying off the grid (grey zone), however you are only receiving 3.3c/kWh for the electricity that you are exporting to the grid (orange zone). *

* Please note that Minimum Feed-In Tariffs and electricity costs vary depending on your location, your supplier, the time of purchase, your state government laws & policies, etc. These figures are based on averages. Check your electricity bill and find out what you are paying.

THE SOLUTION: SINEXCEL ISUNA

The Sinexcel ISUNA Hybrid Energy System is the ultimate energy management solution, giving you complete freedom to create the most efficient and cost-effective way of managing your energy requirements. The system consists of an ISUNA hybrid inverter, battery storage and a power meter.

  • Reduce your energy costs
  • Increase energy availability
  • Instantly provide power in the event of a blackout.
  • Modular, easily customisable for your site.
  • SiC technology = highest efficiency possible.
  • Easy-to-use App and superb support.


GRID-CONNECTED APPLICATIONS




Using ISUNA as a hybrid grid inverter to generate electricity from solar panels with energy storage (battery).

  • Buy energy from the grid now and export later.
  • Buy energy from the grid and use later.
  • Use battery to supplement grid power under high demand when grid resources are limited.
  • Instant back-up power in the event of power outages.
  • You have full control!


OFF-GRID APPLICATIONS



Using ISUNA in Off-Grid mode to generate electricity from solar panels & energy storage with NO grid support.

  • Achieve independence from the grid.
  • Total self-sufficiency.
  • Generators are optional, depending on the site and power requirements.
  • Reduce carbon footprint.

ACHIEVE ENERGY FREEDOM & SAVE MONEY

With load management, instead of exporting that excess solar energy, ISUNA can store your energy for use at a later time, heat your hot water or charge your EV . For off-grid applications ISUNA can also control your generator.

ISUNA can be used to reduce site peak demand, limiting import and export at different times of the day and can improve site capacity with active phase balancing on three phase models. It has the flexibility to grow with you as your needs and budget change with an expandable inverter ratings from 3kW to 50kW. Technology that allows you to save money and improve power availability. It really gives you ultimate control and freedom to manage your energy.

Isuna - Make solar work for you

SIC TECHNOLOGY

The use of robust SiC (Silicon Carbide Mosfet) technology enables the hybrid inverter to operate at unprecedented high frequencies with the highest efficiency on the market. Apart from unparalleled high performance, much less heat is produced which has a dramatic impact on ventilation requirements and the sizing of supporting components. This in turn has resulted in extremely compact, light weight physical unit sizing and a longer more reliable life cycle. ISUNA is a quiet addition to any site, reducing or eliminating the need for fan cooling, and reducing maintenance. The support from Fuseco and Sinexcel is second to none, making ISUNA the premier quality energy management solution in Australia.

Isuna - Why Sinexcel Isuna

BATTERY EXPANDABILITY & COMPATIBILITY

ISUNA can support more than one battery with independent inputs and BMS (3-phase models). Add new batteries as your needs expand while retaining existing batteries. Most single input systems require existing batteries to be replaced during a capacity upgrade.

ISUNA can support lead acid, lithium and sodium battery technology as well as batteries from different brands. This allows use with existing battery installations, protecting previous financial investment. Compatible with lead-acid policy sites & existing infrastructure.

Both of these features are unique to ISUNA and represent significant medium to long term cost savings.

Isuna - Battery Expandability & Compatibility

MODULAR, FLEXIBLE & AFFORDABLE!

ISUNA is a modular system, allowing you the freedom to locate the inverter, the battery storage & power meter wherever is best for the site. Inverters can be paralleled to increase capacity and you can add more battery storage resources where needed. This flexibility allows customisation and is great when you need to combine existing equipment, place components where they function best or for larger system designs.

Along with the two independent battery inputs on larger capacity inverters, facilitating the use of both battery ports at the same time, the ISUNA is the most flexible and adaptable energy management solution in the market.

Isuna - Uniquely expandable and affordable

WHY SINEXCEL ISUNA?

Prior to Sinexcel entering the power electronics market in 2009, devices such as Active Harmonic Filters (AHF) were physically large, limited in their performance and very expensive. Sinexcel introduced a suite of technologies that ushered in a new era of ultra-compact, high efficiency electronics that transformed the power quality and energy management industries, also being the first company to produce wall-mounted versions of these devices. Their 3-level topology and SiC (Silicon Carbide Mosfet) technology re-defined performance levels, physical sizing and pricing levels.

Sinexcel have been manufacturing inverters for over 14 years and with thousands in service around the world, including large government infrastructure projects, the brand has proven to be very reliable and has become the first choice for power engineers nationwide.

ISUNA Sinexcel Testimonial - IGC

My positive experience began with the consultation process. The way Fuseco explained the technology & proposed a custom system to suit my facility was very professional & informative. Once the system was installed, the financial benefits were obvious immediately. I predict that in a couple of years, everyone will be running an ISUNA!

ISUNA Sinexcel Testimonial - IVE GROUP

Reducing our grid dependency  was really important to us. We had made a significant investment in solar panels but the results were not optimised until we installed an ISUNA system. We saved a lot of money and significantly reduced our carbon footprint. Great system!
