Aoboet Battery: An Independent Review by Solar Choice

Background on Aoboet – Company History

Aobo Environmental Technology (Aoboet) was founded in Wuxi City, China in 1999 and initially focused on the design and manufacture of industrial dehumidifiers. Aoboet have sold their dehumidifier products across Europe and Asia and have received international safety accreditation under ISO9001:2015.

In 2017 they started researching and development of energy storage system products. In 2018, they had a product launch for the energy storage systems in October in Melbourne, Sydney and Brisbane and released Aoboet brand solar energy storage systems in Australia.

The company declared a profit after tax of $748,205 in June 2020, up from $212,100 in June 2019 – making them comparatively a small player in the solar battery storage market.

Over the last couple of year Aoboet have been establishing distribution channels with ATS Products and Energy Storage Systems and obtaining the necessary approvals to sell their products under the state-based rebate schemes. 

 

Basics of Aoboet UHOME NCA Battery

The Aoboet UHOME NCA is their flagship product in Australia. With a 6.8kWh nominal storage capacity, this battery uses Panasonic manufactured cells and a Battery Management System (BMS) developed by Aobo.

With a usable capacity of 6kWh, it uses Panasonic manufactured cells and a battery management system developed by Aobo. The “NCA” stands for Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2), the chemistry of the cells used in the battery.

As per their datasheet, the maximum number of modules that can be connected in parallel is 4, which would provide a battery system totalling 27.2kWh. This scalability would place it within the range of either residential or commercial applications.

At 62kg it’s fairly heavy compared with other battery modules. This is likely due to the combination of metal and plastic casing as it’s designed for both indoor and outdoor use as it’s rated IP65.

With an operating temperature of -10 to 45 degrees Celsius places it to work well in the temperature extremes of the Australian environment. On that point, they’re developed with Nickel Cobalt Aluminium Oxide which is well known for their chemical safety with batteries, as well as providing a long cycle life.

They state on their documentation that the product has as high compatibility with many different inverter brands, however no specifics have been stated. We’ve reached out to Aoboet to clarify this.

 

Aoboet Battery – Key Features Aoboet home battery

There are a number of features of the Aoboet battery worth mentioning:

 

Scalable Capacity

As mentioned, this battery can be expanded in parallel with 4 modules giving a total of 27.2kWh. The advantage with this, is that it gives you the flexibility to expand your solar energy storage in the future. This may be useful if you’re finding that you’re finding your battery stretched with your night time use of appliances.

 

90% Depth of Discharge

The Depth of Discharge (DoD) of the Aoboet UHOME NCA is 90%. This puts it on par with some of Aoboet’s competitors, namely Sonnen (90% DoD and Alpha ESS (90% DoD).

We recommend that consumers compare batteries based on the usable capacity rather than their nominal (or ‘nameplate’) capacity. You can determine the usable capacity by multiplying the nominal capacity by the depth of discharge.

Smart App

Aoboet self-developed APP complements the product for easy monitoring by both customers and Aobo. The benefit of this app is that it enables the user to both monitor and optimise their electricity consumption. Also, you can switch to charging up your battery system during off-peak tariff periods.

Australian Warranty Terms for Aoboet UHOME NCA Batteries

The Aoboet battery comes with a 10 year or 21,000 kWh warranty – whichever is shorter. That means if you are able to discharge 21,000 kWh in less than 10 years as recorded in the battery smart app then the warranty policy will expire.

Until the end of the warranty period the battery is guaranteed to retain at least 60% of its nominal energy (4.08 kWh) which allows for the natural degradation over 10 years and many cycles.

One concerning part of their warranty document, which looks like it may have been translated from Chinese, is that the below statement which indicates only 5 years of the warranty policy is for free. No further information on what this means or what the additional 5 years would cost is included in the warranty document.

“5 years for free + 5 years appropriate transport costs”

Battery government rebate schemes across Australia

South Australia, New South Wales, Victoria, and Australian Capital Territory all currently have a home battery scheme in place.

The South Australian Home Battery Scheme enables eligible South Australian residents to receive up to $4,000 per installed battery.

The New South Wales Home Battery Scheme offers an interest-free loan up to $9000 for eligible households looking to install a solar battery.

The Victorian Government under the Solar Homes Program provides eligible customers a maximum discount of $4,174 off the battery sale price. 

The Australian Capital Territory Government under the Next Generation Energy Storage program provides a rebate of $825 per kilowatt (kW). An average household with a 5kW system would be eligible for approximately $4,000.
