Are GoodWe batteries any good? An installer’s honest view

GoodWe is the mid-tier battery we install, and we are comfortable fitting it. The ESA we install is an all-in-one unit with a hybrid inverter and stackable battery modules. We cannot promise how any battery will perform for you, so here is what the maker’s own manual says, what to check on any battery, and who a GoodWe suits.

What GoodWe’s manual says

  • Sealed: the inverters in the manual are rated IP66 (protected against dust and powerful water jets) and suitable for indoor and outdoor installation.
  • Quiet: noise emission is listed at 30 to 35 dB, depending on the model, with natural convection cooling (no fan on those inverters).
  • Scalable: the battery system is modular, supporting 5 to 108 kWh of storage, and modules are stacked.
  • Backup: there is a dedicated BACK-UP port for whole-home or partial backup, depending on how it is wired.
  • Monitoring: Wi-Fi, LAN and Bluetooth, with the SEMS+ app and the SEMS+ web portal. See SEMS portal vs SEMS+ app.
  • Cold weather: the manual describes battery heating and lists charge and discharge temperature ranges.

What to check on any battery, GoodWe included

The Australian Government suggests: check the battery is on the Clean Energy Council approved list, read the warranty conditions, ask how long the maker has been in the industry and whether it has an Australian office, whether it can identify a battery by batch number if there is a fault, and whether it has recall insurance. We are happy to answer these for any battery we install, and we only recommend what we are comfortable standing behind with our 25-year workmanship warranty on the install.

Coastal homes: a check we make

Both makers flag salt air. GoodWe’s manual says to consult the manufacturer before installing outdoors in a salt-damage area, which it describes as within about 500 metres of the coastline. Sigenergy’s manual says to install at least 500 metres from corrosion sources such as the seaside. Many Northern Rivers homes are near the coast, so we check your exact position at the site visit and talk through the options, rather than assume.

Who a GoodWe suits

  • Homes that want proven brand quality at a mid-tier level, with backup and room to add modules.
  • People who want a quiet, outdoor-rated unit.
  • If you want to charge an EV directly from the battery or want the biggest expandability in one stack, compare with Sigenergy: Sigenergy vs GoodWe vs Tesla.

Questions we get asked

Are GoodWe batteries reliable?

We cannot promise reliability for any brand. GoodWe publishes ratings and a manual, and warranties apply; ask for the warranty document before you buy.

Is GoodWe cheaper than Sigenergy?

GoodWe is our mid-tier option and Sigenergy our premium. Pricing depends on your design, so we quote after your free assessment and site visit.

Can a GoodWe battery power my home in a blackout?

Yes, if it is configured for backup. The ESA has a backup port; we design which circuits it covers with you.

Is a GoodWe battery eligible for the federal rebate?

If the exact model is on the Clean Energy Council approved list and the install is eligible, yes. We check before it goes in your proposal.
