• High weighted efficiency: Achieves a weighted efficiency of 99% for 5kW to 10kW models.
• Dual warranty structure: Inverters carry a standard 12-year warranty (extendable to 20 or 25 years), while rooftop power optimisers carry a 25-year warranty.
• Comprehensive product portfolio: Single-phase residential units alongside three-phase models spanning 5kW to 100kW.
• Dedicated local infrastructure: Australian office with a structured warranty claim process and local support staff.

Technology Overview: DC Optimised Architecture

Established in 2006, SolarEdge developed the DC optimised inverter solution that changed the way power is harvested and managed in photovoltaic (PV) systems.

Solar Edge is best known for pioneering the concept of a string inverter matched with individual power optimisers. In a standard solar installation, solar panels are wired in series strings into a conventional inverter. If a single panel experiences shading, soiling, or manufacturing tolerance mismatch, the current through the entire string is choked.

SolarEdge resolves this mismatch by splitting inverter duties into two distinct stages:

1. Module-Level Power Optimisers: Small electronic boxes bolted directly underneath each solar panel that perform Maximum Power Point Tracking (MPPT) at the individual module level.
2. Simplified Central Inverter: A wall-mounted unit whose primary responsibility is converting DC power to AC electricity with extraordinary conversion efficiency.

Record-Setting Efficiency: HD-Wave Technology

The engineering hallmark of SolarEdge residential hardware is HD-Wave technology. By employing advanced digital signal processing to synthesize a clean sine wave, SolarEdge eliminated the bulky copper cooling components and magnetic transformers found in older inverters.

This delivers measurable efficiency gains: while efficiency standards for residential inverters are generally 95 to 98 percent, SolarEdge achieves a maximum efficiency of 99.2 percent. Furthermore, SolarEdge delivers a weighted efficiency of 99% for 5kW to 10kW models.

This greater efficiency will lead to a slight increase in energy production over the lifetime of a solar system and compliments the other advantages of the power optimisers. Less wasted energy as heat also reduces thermal stress on internal electronic components.

Product Portfolio: Single-Phase HD-Wave vs Three-Phase Commercial

The SolarEdge range covers everything from compact suburban cottages to expansive commercial rooftops.

Single-Phase Residential Inverters

SolarEdge single-phase inverters are designed for residential solar PV systems, where the power output is usually lower than that of commercial or industrial systems. The flagship residential model installed across Australia is the Single Phase Inverter with HD-Wave Technology 5.0kW.

Physical unit dimensions remain remarkably compact: dimensions with safety switch/connection unit measure 450 x 370 x 174 mm, allowing neat installation in space-constrained carports or utility corridors.

Three-Phase Inverters

For homes with three-phase grid connections and commercial properties, SolarEdge provides three-phase inverters from 5kW to 100kW, with a maximum efficiency of up to 99.2%. The entry three-phase unit is the SolarEdge 3-Phase Range 5.0 kW, maintaining phase balance and compliance with distribution network rules.

Battery Integration: SolarEdge Home Battery

Homeowners seeking energy storage can pair their HD-Wave hardware with DC-coupled storage. Connecting storage on the DC side of the inverter avoids the round-trip conversion losses inherent in AC-coupled systems.

Dual Warranty Architecture & Melbourne Support

SolarEdge provides one of the strongest standard warranty packages in the solar industry:

• Inverter Warranty: The Solar Edge inverters have a 12-year product warranty. The standard 12-year product warranty for the inverter is unparalleled in the industry, and is a great indicator of high quality. The inverter warranty can also be extended to 20 years and 25 years with most of their residential models.
• Optimiser Warranty: The accompanying power optimizers have a 25-year warranty. As the power optimisers are located on the roof and exposed more to the elements, a 25-year warranty provides peace of mind to owners for the expected life of a typical solar system.
• Local Australian Support: SolarEdge has an Australian office and a clear warranty claim process on their website. Homeowners and accredited installers receive responsive diagnostic support and RMA processing from local support staff.

Clean Energy Council Approval & SRES Compliance

Under the Australian Small-scale Renewable Energy Scheme (SRES), rooftop solar installations must strictly list its panels and inverter on the Clean Energy Council list of approved products to remain eligible for financial incentives.

All SolarEdge inverters and power optimisers sold in Australia meet Australian and New Zealand standards, complying fully with voltage regulation, anti-islanding protection, and electrical safety standards.
