GoodWe Batteries: Independent Review by Solar Choice

Background – Who is GoodWe?

Jiangsu GoodWe Power Supply Technology Co Ltd, founded in 2010 in Suzhou, China, and are primarily known as a manufacturer of solar inverters. The have typically provided a feature rich but lower cost option to some of the mainstream European brands.

GoodWe entered the solar battery market in 2021 with the first version of their Lynx home battery. They have since brought out newer models and different variations. Their batteries, like their inverters, are manufactured in their main factory in Suzhou, China.

Goodwe have operated a local office in Australia since 2012 and have a well established service model for Aussie customers.

How much does a GoodWe Battery Cost?

Based on quote information uploaded by Solar Choice’s pre-vetted network of reputable battery installers, the average cost of installing a GoodWe battery is $13,000 for their 10.3 kWh model including installation.

This places GoodWe in the middle in terms of price comparison. They are cheaper than premium options like Enphase or Senec, but more expensive than some other Chinese manufacturers like Sungrow or Alpha ESS.

GoodWe Battery – Range and Models

For residential customers, there are 3 main models to choose from. All of their batteries use lithium iron phosphate (LFP) battery cell chemistry.

Lynx Home U Series

The Lynx Home U Series is a low voltage battery solution which is only compatible with GoodWe’s ES and SBP inverters. The battery comes in increments of 5.4 kWh (usable) and you can combine 6 modules to create a total capacity of 32.4 kWh.

The battery can be wall or ground mounted and is rated IP65 which means it can be installed indoors or outdoors.

Lynx Home F Series

The Lynx Home F Series is GoodWe’s high voltage battery solution with an operating voltage range of 273.6V ~ 345.6V for their LX F9.8-H model. Higher voltage batteries typically cost more than lower voltage batteries but offer faster charging and discharging rates. Their LX F9.8-H (Home F) model can be discharged or charged at 9.2kW while their equivalent Home U Series 2*LX U5.4-20 model can only discharge or charge at 5.12 kW.

This series is a stackable solution which is able to be stacked with battery capacity between 6.6 kWh and 16.5 kWh (usable).

The Lynx Home F Series can only be ground mounted and has a slightly lower environmental protection rating of IP55 which is still rated for outdoors.

This battery is compatible with GoodWe EH and ET inverters.

Lynx F G2 Series

Like the Lynx Home F Series, the Lynx F G2 batteries are stackable, high voltage and appear very similar. The Lynx F G2 is compatible with GoodWe BH/EH/BT/ET inverters.

This solution however features their newer battery modules which are rated individually at 3.2 kWh. This battery comes with a minimum of 2 modules (6.4 kWh) and can extend all the way to 9 modules (28.8 kWh) in one tower.

This battery has a slightly improved warranty including a minimum cycle life of 4,000 cycles and a retention of 80% of its battery capacity after 10 years – read more in the warranty section below.

GoodWe’s Warranty for Australian Battery Customers

Solar batteries can come with a product warranty to protect against defects and a performance warranty to protect against degradation beyond certain parameters.

All of GoodWe’s different battery models come with a 10-year product warranty. This is broadly seen as the market standard for solar batteries, although you do see some models with a 5 year warranty, and at the time of writing only Enphase has a longer 15 year warranty.

GoodWe’s Lynx F, Lynx U and Lynx F G2 series offer a guarantee the battery retains 70% of the nameplate capacity after 10 years or a minimum throughput as described in the below table (whichever comes first):

GoodWe have chosen to include some tricky wording in the warranty coverage of transport and labour costs, which seems it all falls back to their discretion on whether its covered. Additionally GoodWe are not disclosing the rates and maximums they will cover for these items and instead state “please contact GOODWE for the rate”. This is not very pleasing for a customer to see.

However GoodWe do have a local office in Rowville, Melbourne and support team to assist with warranty enquiries. You can contact them via service.au@goodwe.com or 03 9118 3905.

Pros and Cons of GoodWe Batteries

Pros

• Stackable battery options provide flexibility and ease of installation
• Reliable manufacturer with established local presence in Australia

Cons

• Only compatible with GoodWe inverters
• Slightly more expensive that other Chinese manufactured batteries
• Unclear warranty wording on what costs would fall back to the consumer

Is the GoodWe battery worth it?

GoodWe are a well known brand in the solar industry, mainly for their cost-effective and function rich solar inverter range. Their batteries look to mainly designed for customers who have already installed or who are in the process of having a GoodWe inverter system installed. The battery, solar and even a GoodWe EV charger can all be managed via one app which makes life easy for customers.

The main drawback seems to be their unclear warranty terms. Given they have only been in the battery game since 2021, the longevity of their battery systems is not as well proven as some other names in the battery market.
