Uhome Lithium Batteries In Brief:

Uhome Lithium Batteries are a robust battery brand. They have advantages and disadvantages, so here at ESE Solar they are not one of our frontline battery brands, but we do install them for some customers when their use is appropriate.

Their big advantage is superior performance in cold weather: they have little performance reduction compared to many other companies’ battery products when the temperature drops. This means you can put them in a garage or loft without worrying that the system will degrade in cold conditions.

These batteries have a great charge and discharge rate of 30 amps which means faster charging. They have a built-in modem so that each battery can be connected to the internet for remote diagnosis, problem-solving and firmware upgrades: this is an advantage over other systems where the monitoring is done via the inverter software.

  • The batteries can be connected in either parallel or series for use in low voltage systems like most residential solar arrays or can be connected in series to create high voltage capacity.
  • The high quality engineering of the battery hardware ensures very good performance and power loads.
  • When used in conjunction with a combiner box a single stack can charge and discharge at 7 kW when paired with the correct controller.
  • 6000 amps warranty: this is a long warranty compared to some others.
  • Easily expandable with multiple controllers for one stack of batteries.
  • Anti-stalling programme: battery can be brought online and offline quickly.
  • Disadvantages: the batteries are not dustproof. They are also large and unwieldy compared to some competing units, so are not suitable for installation in tight spaces.

 

AOBOET Company Overview:

AOBO Environmental Technology (AOBOET) has been making batteries for 18 years. Headquartered in Chengdu, Sichuan province, China – where the pandas come from – it prides itself on creating advanced battery technology for a wide range of applications.

AOBOET Uhome Battery Specifications

AOBO Uhome batteries claim to have advanced features which are superior to other batteries.

Uhome batteries do not show a reduction in performance in cold temperatures, compared to many lithium batteries; they remain at full capacity down to zero degrees Celsius. In addition, each battery has superior charge and discharge rates of 30 amps which means faster charge and discharge capability. Each unit has an inbuilt individual modem, which means the simple connection of each battery to the internet allows specific monitoring, technical support and future upgrades where needed.

The batteries can be connected in either parallel or series. If used in residential low voltage systems typical of most domestic solar arrays, parallel connections are used.  They also can be connected in series to create high voltage capacity.

The exceptionally high specification hardware on the batteries allows for very high performance and power loads.

When used in conjunction with a combiner box a single stack can charge and discharge at 7 kW when paired with appropriate controllers.

Expandable Setup

Uhome battery storage systems can be supplied and installed with one to eight batteries. Most ESE Solar customers start with either a two or three battery system and later add extra batteries if required.

Fast Charge and Discharge Rates

Most lithium batteries available today require a minimum of three batteries in order to achieve the maximum charge and discharge rate of 3 kW. With just two of Uhome 2400 batteries the system can achieve up to 3.5 kW and a maximum of 3.6 kW with three or more batteries attached to an appropriate controller.

Uhome Battery Pros and Cons

Pros:

  • Uhomes have a good discharge rate of 1.5 kW per battery
  • They have battery-by-battery monitoring
  • Each battery has a modem so it can be linked up to the internet and ESE Solar can remotely monitor and diagnose each battery individually in case of problems with the system.
  • Very robust and temperature-resilient
  • Good warranty

 

Cons:

  • Not dustproof
  • Rather large and unwieldy units

 

Uhome Battery FAQs

Q: How long will a Uhome battery last?

A: Generally lithium batteries tend to last around 10-15 years. With the lifespan of a solar panel being over 25 years normally, you should expect to replace the batteries once during that time.

Q: Are Uhome batteries worth having from a financial perspective?

A: It depends on your system, the location and weather, and how much electricity you use. Batteries are an additional cost, but they also allow the solar energy producing system to be more efficient and also can store electricity you generate yourself or off-peak power from the grid, thus saving money.

Uhome Battery Summary

These Uhome batteries are certainly a product to be considered, if there is the space to install them successfully. Their SMART monitoring abilities and robust performance makes them a good brand, particularly if their location is likely to be cold for some of the year. 

Uhome batteries are easily expandable so can grow with the development of your home solar system. That said, they are somewhat bulky and heavy, so this can be disadvantageous in some situations. 

Overall, consult your ESE Solar supplier and we will recommend the best type of battery for your particular energy installation.

Born in North West England, Jack kicked off his career in the insurance arena, dealing with claims for three years. Always up for a challenge, Jack leapt out of his comfort zone and embarked upon 5 years of excitement with the military.

Working for the Ministry of Defence, Jack specialised in counter-terrorism which took him to places such as Dubai, Oman, Iraq, Norway and Bahrain. During this period he worked with various Governments implementing strategic operations to prevent terrorism.

After travelling around various countries Jack increasingly came across various forms of solar from large solar farms to domestic solar panels. From here Jack took a keen interest in all things solar and started reading about the technological capabilities with a view to entering the industry after his career in the Ministry of Defence.

Once home after 5 fruitful years, Jack had 3 months leave in which he immersed himself in a solar crash course and got applying for jobs within the solar sector. He came across ESE Solar, a long-established forward-thinking company whose head office was only a stone’s throw away from him. He picked up the phone to see if there were any vacancies and within a week had a successful interview and obtained a full-time job, starting in the technical team.

Within the first few months, Jack onboarded in various online courses during work and social hours to speed up his knowledge of all things solar. Due to his strong work ethic and thirst for knowledge Jack was promoted to Head of Technical at ESE Solar. He currently leads the team and oversees the product development of new technologies within the company alongside assisting where necessary on their maintenance department.
