SunBuilt Solar is a certified Sigenergy installer based in Canberra, supplying and installing the Sigen EV AC Charger across the ACT and surrounding region — Tuggeranong, Belconnen, Gungahlin, Woden, Weston Creek, Inner North, Inner South and Queanbeyan included.
The Sigen EV AC Charger is a smart, solar-aware home EV charger that talks directly to your solar inverter and battery. Rather than pulling whatever's available off the grid, it can be configured to prioritise free rooftop solar, draw from off-peak tariffs, or top up from your SigenStor battery when the sun's not playing along — so the cheapest, greenest electrons charge your car first.
As a NETCC-approved retailer with CEC-accredited electricians, we handle the full job: site assessment, switchboard and cable run review, Evoenergy notification, install, commissioning and ongoing support — all by the same Canberra team.
Standard Type 2 connector (the AS/NZS standard in Australia). 7 kW for single-phase homes, up to 22 kW for three-phase installs.
Fast charge, solar-surplus charge, battery-boost charge and tariff-aware AI mode — pick the right one for the trip ahead.
Reads household load in real time (with the optional Sigen Power Sensor) and dials the charger up or down to stay within your main fuse limit.
Click-in mounting and rear, top or bottom cable entry — a clean, tidy install on a brick wall, garage stud or carport post.
Match the mode to the moment — cheapest grid hour, free rooftop solar, fastest possible top-up, or a boost from your SigenStor battery. Switch between them from the mySigen app on your phone.
Tariff-aware charging that watches your ACT time-of-use plan and only draws grid power when it's cheap. Pauses when prices peak, prioritises rooftop solar surplus, and quietly tops the car up overnight — set it once and forget it.
Cheapest electrons firstWhen you need range fast, the charger pulls a full 22 kW (on three-phase) by blending solar, grid and SigenStor battery output. Useful before a Snowys, South Coast or Sydney run when there's no time to wait for the sun.
Up to 22 kWThe charger only runs on solar your roof is about to export — so daytime production charges the car instead of feeding back at low FiT rates. Set whether the EV, the battery or the home gets first dibs on surplus PV.
Solar-only chargingTop the car up at full speed using stored SigenStor battery energy after dark — perfect for late returns home. Set a cut-off SOC (10–90%) so the battery still has enough headroom for the morning's house loads.
Day or nightSunBuilt Solar installs Sigenergy EV chargers exclusively. Sticking to a single ecosystem means the charger, your solar inverter, your battery and the monitoring app are all speaking the same language — so solar-priority charging, load balancing and scheduled charging actually work the way the spec sheet says they will.
The right model depends on your supply (single- vs three-phase) and how far you typically drive each day. We'll talk you through it during the quote.

Get a QuoteWe install Sigen EV AC Chargers right across the ACT — Belconnen, Bruce, Dickson, Lyneham, Watson, Gungahlin, Harrison, Forde, Casey, Woden, Mawson, Curtin, Weston, Wright, Coombs, Tuggeranong, Greenway, Conder, Gordon — and into Queanbeyan and the surrounding NSW region. Quotes, installs and warranty visits are all done by the same Canberra-based crew, not subcontracted out.
The ACT also offers strong support for EV owners: zero-emission vehicle stamp duty exemptions, the Sustainable Household Scheme zero-interest loan for energy upgrades, and time-of-use electricity plans that reward off-peak charging. Talk to our Canberra team about pairing a Sigen EV AC Charger with your existing solar — or as part of a full SigenStor system.
Yes, the charger works as a standalone unit on any Australian solar setup — it'll still charge from grid-tied solar surplus via a power sensor. You unlock the full feature set (priority adjustment, battery boost, AI tariff mode) when it's paired with a Sigenergy inverter or SigenStor. We'll assess your existing system during the quote and tell you exactly what works and what doesn't.
