Product Description   

Dream energy Lithium battery solutions are highly integrated, deep cycle backup power solutions for your solar home energy storage system. With rich experience and advanced techniques, the product has the features of the fashionable design, high energy, high power density, long service life, and easiness of installation and expansion.
There are currently two types of home energy storage systems, one is grid-connected home energy storage system and the other is off-grid home energy storage system. Home energy storage lithium battery packs give you access to safe, reliable and sustainable energy and ultimately an improved quality of life. Home energy storage products can be installed with home energy storage lithium battery packs, whether in photovoltaic off-grid application scenarios, or even in homes without photovoltaic systems.
The home energy storage lithium battery pack has a service life of more than 5 years. The modular design allows multiple energy storage units to be connected in parallel in a more flexible manner, which is simple and fast, and greatly improves the storage and utilization of energy.

  • The expected design life is up to 15+ years

  • 5 years warranty;

  • Greater depth of discharge (DOD 90%) compared to Lead-Acid/AGM/GEL battery(DOD 50%);

  • Single battery module capacity of 5 kWh;

  • Working temperatures of between -20°C to 55°C (Charging 0~50°C; discharging -20~55°C);

  • More stable and safer LFP internal battery cells, allowing an increase in the combustion temperature of600°C compared to 300°C relatives to NMC and LCO;

  • Battery Management System (BMS) automatically manages the charge/discharge state and balance current/voltage of each cell. BMS enables protection functions including over-discharge, over-charge,over-current protection and high/low temperature protection;

  • 19-inch standard module battery design, easy installation, DIY friendly, and expansion up to 8 modules that makes the total capacity to 41kwh in a single 19-inch rack;

  • Natural cooling allows the battery to achieve the highest energy efficiency and no fan noise.

Below are the answers to the questions that you may like to ask for


Can I charge the battery from the mains?

Short answer is yes but it will require a hybrid inverter. This would mean you could charge the battery at a cheap night rate from the grid as well as charging the battery from the solar PV.

Can I have an Uninterrupted supply (UPS) if there is a powercut?

Yes but would need to be wired to a dedicated circuit within the house, for example the upstairs sockets and downstairs lighting, this would then provide you with emergency power in the event of you losing the mains.

What’s the best location for batteries?

They work best in a room that doesn’t get too hot – Ideally they would go in a garage but they can go in a loft or any other room but the warmer they get the less efficient they become. The operating temperature ranges from -10 to 50 degrees but will see efficiency drops below 0 and above 40 degrees

Are Batteries safe?

Batteries are no more unsafe than any other electrical installation, as with anything there are risks but these are very small and should be a great consideration.

Can I add more batteries at a later date?

Yes, YuYang Energy batteries can accept a further 14 battery packs taking, the total capacity can reach to 76.8kWh with 15 packs of 51.2V 100Ah battery. 

How long do they last?

This is actually determined by the number of cycles the battery goes through, this means a full charge and discharge. On average a battery will last around 10 years and all batteries have at least a 5 year warranty and most can be extended to 10-years.

What’s the difference between Capacity and useable capacity?

Most batteries will have a capacity and a useable capacity – this can be confusing but in basic terms batteries should never been fully discharged and as such the useable capacity takes this into account.
