GoodWe vs Sigenergy: Which Battery System Would We Choose?
GoodWe’s latest battery system looks remarkably similar to Sigenergy and comes in at a significantly lower price. But does that mean you’re getting the same technology for less?
In this video, Dan from GI Energy compares the GoodWe ESA and Sigenergy SigenStor across battery technology, warranty, backup performance, software, EV integration, pricing, and the overall energy ecosystem.
Quick Answer
We would choose Sigenergy.
GoodWe offers a very competitive system, especially for homeowners working with a tighter budget. However, we believe Sigenergy currently provides the stronger overall platform, with:
✅ Stronger battery architecture
✅ Greater warranted battery throughput
✅ More mature energy-management software
✅ Highly integrated backup capabilities
✅ A clearer pathway for EV and bidirectional charging
✅ A broader, more established energy ecosystem
GoodWe’s biggest advantage is price, and for someone looking for a straightforward battery system with a strict budget and a quality installer, it may still be a very reasonable option.
But if the question is which system we would feel more comfortable owning for the next 10–15 years, our choice is Sigenergy.

FAQs
Is GoodWe cheaper than Sigenergy?
Yes. Price is one of GoodWe’s strongest advantages, and depending on the system size, installer, and included scope, the difference can potentially be thousands of dollars.
Is GoodWe basically a cheaper Sigenergy?
We don’t believe so. Although the systems share a similar appearance and many comparable headline features, there are meaningful differences in battery architecture, warranty throughput, software maturity, integration, and the overall ecosystem.
Which battery has the better warranty throughput?
Based on the current Australian warranties discussed in the video, Sigenergy provides approximately 23% more warranted throughput per usable kWh than the comparable GoodWe system.
Which battery has better backup performance?
Both systems provide very fast backup switching. Sigenergy specifies zero-millisecond load disruption, while GoodWe specifies approximately four milliseconds. For most household appliances, either is extremely fast.
Which system has better software?
We currently consider Sigenergy’s software and energy-management ecosystem more mature. Its platform has been designed around integrating solar, batteries, backup, smart energy management, dynamic tariffs, EV charging, and other household energy requirements.
Can Sigenergy integrate with an EV?
Yes. Sigenergy offers an integrated 25kW DC EV charging option and has a pathway toward bidirectional vehicle-to-home and vehicle-to-grid functionality with compatible vehicles and supporting infrastructure.
Is GoodWe still a good battery?
Potentially, yes. GoodWe offers respectable specifications and aggressive pricing. For homeowners who want a relatively straightforward battery system, have a strict budget, and are working with a reputable installer, it can be worth considering.
What matters more: the battery brand or the installer?
Both matter, but installation quality is critical. Even a great battery can perform poorly if the system is incorrectly designed, installed, commissioned, or supported.
Thinking About a Home Battery?
Choosing between GoodWe, Sigenergy, Tesla, BYD or another battery shouldn't come down to the logo on the front or the cheapest quote.
The right system depends on your home, energy consumption, solar production, backup requirements, future EV plans, electricity tariff, and how you want to use your battery over the next decade.

It worked out to be only a 4% difference.
But DYOR.
For the installer that quoted both sigenergy and goodwe, using the exact same panels, the sigenergy price was over $7K more at the time, for the same size inverter and battery capacity.
So granted, based on what you say, that sigenergy is overall a bit better, but it's not like it's massive amounts better then goodwe (putting aside that the software is constantly evolving and being updated) and having to recover an extra $7K ROI is a big ask for something that for the most part, still does the same job.
Needless to say, I went with goodwe and so far (after it's been running for 3 months), it's all worked as expected. If I'll be saying the same thing after 3 years or more, I don't know, but then it does all have a 10 year warranty, so I should be fine.
I checked out Sig with another respected solar / battery company, and the 3 x 10kwh (27 usable) fitted fine, a lot less in height.
To boot, it was cheaper than both other options !
6 weeks and it's booked for install onto existing solar.
Loving the SigEn battery and got it set up on a time schedule so it only imports between 14:00 and 15:00 if the battery is below 80% and exports 8-10 kWhrs between 18:00 and 20:00 at 4-5 kWhrs /hr and a window between 01:00 and 06:00 if the battery gets below 20% which would be if I run the A/C overnight on a hot/muggy night. I have also limited battery charging /discharging to 10kW to coddle the battery in case solar + grid is potentially higher.
Also, a local electrician who has a battery setup just burnt his house down last week. How common is this becoming?
Currently using a normal 10A charger for my Tesla
Hopefully the price of DC EV charger can reduce to less than $2000
