What Renewable Energy Solutions Australia(RESA) does

Renewable Energy Solutions Australia (RESA) is a Brisbane-based, privately-held Australian company that designs, manufactures, and sells renewable energy hardware targeting commercial, industrial, agricultural, and residential customers across Australia. Its flagship product is the Eco Whisper Turbine, a mid-sized silent wind turbine featuring a proprietary 30-blade design claimed to be virtually silent and up to 30% more efficient than conventional 3-bladed turbines; the commercially available 650 model generates up to 20 kW within a 21 m2 footprint, while a smaller 325 model (5 kW) for residential use remains in development.

RESA monetizes exclusively through hardware sales. The Eco Whisper Turbine is sold directly to end customers across multiple verticals including airports, ports, mining, councils, industrial parks, and agricultural/remote sites, with only one confirmed commercial installation to date (Tullamarine, Victoria, 2011). The company has extended into solar power electronics through its wholly-owned subsidiary, RESA Electrical Manufacturing (REM), which produces the VoltLogic STATCOM/inverter — an AS4777-certified multi-function hybrid inverter with integrated export control and battery-storage upgrade capability for 5 kW to 30 kW solar PV systems.

The company operates with a small team (11-50 employees), received a single $250,000 AUD Australian government commercialization grant in 2011, and is currently soliciting expressions of interest from sophisticated investors for an early-stage capital raise. RESA's distribution model is direct enterprise field sales supplemented by its website. Aside from one confirmed customer installation, no recurring revenue, customer base, or commercial traction milestones have been disclosed, and the company's public website displays content unrelated to its core renewable energy business, which raises operational continuity concerns.

Core offering

RESA designs, manufactures and sells silent multi-blade wind turbines and smart solar hybrid/inverter systems for the Australian market. Its flagship Eco Whisper Turbine 650 is a 20 kW commercial/industrial wind turbine with a proprietary 30-blade design that operates virtually silently and with a small footprint, while the smaller 5 kW Eco Whisper Turbine 325 targets residential and small-property needs. The VoltLogic multi-function solar hybrid/inverter, manufactured locally in Brisbane by subsidiary RESA Electrical Manufacturing (REM), provides integrated export-power limiting and battery storage support for commercial and residential solar PV systems.

Product overview

Renewable Energy Solutions Australia (RESA) offers a portfolio of renewable energy products centered on silent wind turbine technology and solar power management systems. The core offerings consist of the Eco Whisper Turbine line (comprising the commercially-available 650 model at 20 kW and the developing 325 model at 5 kW) and the VoltLogic hybrid/inverter solution manufactured by subsidiary company RESA Electrical Manufacturing (REM). These products work together to provide comprehensive renewable energy solutions for commercial, industrial, agricultural, and residential applications.

Brands

• Eco Whisper Turbine: World's most advanced silent wind turbine featuring unique 30-blade design, virtually silent operation, and up to 30% more efficient than traditional 3-bladed designs. Available in 650 (20 kW commercial) and 325 (5 kW residential) models.
• VoltLogic

Products and services

• Eco Whisper Turbine 650 Virtually silent, mid-sized wind turbine for commercial and industrial applications, generating up to 20 kW using a proprietary 30-blade design that is up to 30% more efficient than traditional 3-bladed turbines. Stands 21.1 m high with a footprint of only 21 m2 (compared to ~250 m2 for an equivalent-capacity solar array). Targeted at airports, ports, mining, council sites, industrial developments, shopping centers, industrial parks, schools and universities.
• Eco Whisper Turbine 325 Silent wind turbine designed for smaller-scale or residential power needs, generating up to 5 kW. Stands 19.6 m high with a footprint of only 19.6 m2 versus ~50 m2 required for an equivalent solar array. Intended for homes, small properties and council sites; product is currently in development.
• VoltLogic STATCOM/Inverter Multi-function solar power smart hybrid/inverter that can limit export power to the grid from any value between 0 up to the rated power, with export control coming standard and no external relay required. AS4777 approved, hybrid-capable with battery storage support via future upgrade, and suitable for single-phase or 3-phase installations from 5 kW to 30 kW. Manufactured locally in Brisbane by subsidiary RESA Electrical Manufacturing (REM) with full warranty support.

Direct peers

• Bergey Windpower: US-based manufacturer of small and mid-size wind turbines (e.g., Excel 10 kW) for residential, commercial, and remote applications. Closest direct comparable to RESA's Eco Whisper line given overlapping power class, distributed-wind positioning, and focus on noise/footprint-constrained sites.
• Northern Power Systems: Manufacturer of distributed and mid-size wind turbines (e.g., NPS 60-100 kW) targeting commercial, industrial, and remote customers. Comparable in distributed-wind focus, kW range, and emphasis on harsh/remote deployments where diesel displacement is relevant.
• Vergnet: French maker of mid-size wind turbines (Gev HP, 1 MW class) designed for tropical, island, and remote-grid applications. Comparable to RESA in targeting mid-size wind for off-grid and harsh-environment sites, including mining and island microgrids.
• SMA Solar Technology: Global leader in solar inverters and hybrid energy management systems with battery storage and grid-services functionality. Closest inverter-side comparable to RESA's VoltLogic product in terms of hybrid solar+battery inverters for distributed C&I customers.

Broad incumbents

• Enphase Energy: Dominant residential and small-commercial microinverter and battery company. Competes with VoltLogic in the distributed solar inverter market, particularly in export-constrained DNSP territories, though at a much smaller kW class.
• Vestas: World's largest wind turbine OEM, focused on utility-scale onshore and offshore turbines. Represents the dominant incumbent wind competitor; relevant for understanding scale economics that a 20 kW distributed OEM like RESA must overcome.
• Enercon: Major wind turbine OEM with a strong direct-drive technology heritage and broad product range from small to multi-MW. Comparable to RESA in the sense that Enercon's product line shows the challenge of competing across wind power classes, especially at the small end.
• ABB (Hitachi Energy): Supplier of power conversion, STATCOM, and grid-interconnection equipment used in renewable energy projects. Comparable to the VoltLogic STATCOM/inverter capability in providing grid-side power electronics for renewable interconnection.
• Tesla Energy: Provider of Powerwall, commercial battery systems, and solar inverters for distributed C&I and residential customers. Competes with RESA's hybrid inverter/storage pitch and dominates the narrative around distributed renewable + storage economics.

Regional players

• Kestrel Wind Turbines: South Africa-based manufacturer of small and mid-size wind turbines for rural electrification and off-grid applications. Regional analog to RESA in focusing on mid-size wind for remote and emerging-market customers, though operating in a different geography.
