Find the right inverter for your home

String inverters are the most common. They handle solar-only systems and convert DC from a string of panels into AC. Hybrid inverters do the same and also integrate a battery, which is the right choice if you're adding storage now or within 2-3 years. Microinverters sit on each panel and convert at the panel level. They suit shaded roofs or panel-by-panel monitoring, but cost more per kW. For most Perth homes adding solar plus battery, a hybrid inverter is the simplest path.

Match your inverter to your home's electrical supply. Most Perth homes are single-phase (one set of wires from the street); some larger or newer homes are 3-phase. Check your meter or switchboard, or ask your retailer. 3-phase inverters cost more but allow larger systems (10kW+ on a 3-phase home vs 5-7kW max on single-phase) and balance load across phases. Don't oversize a single-phase inverter past Synergy's standard export limit (typically 5kW).

The standard rule is to size your inverter at 75-100% of your panel array's DC capacity. For a 6.6kW panel system (e.g. 15 × 440W panels), a 5kW inverter is the most common pairing. It handles real-world output (panels rarely produce nameplate power) and matches Synergy's standard export limit. An 8kW inverter raises peak production, but export caps will still limit how much reaches the grid. Talk to your installer before sizing.

Hybrid inverters have built-in battery management, so they're inherently battery-ready. Standard string inverters can sometimes be paired with a separate AC-coupled battery (like Tesla Powerwall), but the wiring is more complex. If you plan to add a battery within 5 years, choose a hybrid inverter now to avoid replacing it later. Check the manufacturer's compatible-battery list. Not all batteries work with all hybrid inverters.

Yes. CEC approval is a federal STC rebate prerequisite. All inverters listed in our catalogue are on the Clean Energy Council Approved Products Register. STC value is calculated on system size (kW DC of panels), not inverter size, so the inverter brand doesn't affect rebate value as long as it's CEC-approved. Verify your installer is also SAA-accredited to claim the rebate.

String and hybrid inverters typically come with 5-12 year product warranties. Real-world life is usually 10-15 years. Inverters are the most likely component in a solar system to need replacement. Microinverters often have longer warranties (25 years) because they face less thermal stress. Budget for one inverter replacement during the 25-30 year life of your panels.

Inverter warranties run 5-12 years, so the brand's likelihood of still being around to service a claim matters. Look at how long the manufacturer has been CEC-approved and active in Australia, whether it has AU-based technical support and parts availability, and the length and terms of the product warranty. Confirm current model availability and warranty arrangements with your installer before purchase. Every model in our catalogue is on the Clean Energy Council Approved Products Register.
