Some competitors says that Greenrich is 1.5C discharging rates battery, 1.5C discharging will affect the lifespan. I want to give a example: Think of Buying an Energy Storage System Like Buying a Car for Your Family Imagine you have a Mercedes-Benz. Its speedometer shows it can go up to 280 km/h. This means the car is designed and tested to reach that speed safely. However, most drivers won’t go that fast. When driving at 120 km/h, a Mercedes-Benz is smooth and comfortable. When you need to overtake another car, it accelerates quickly and easily. Greenrich batteries work in a similar way. They are designed to handle a high discharge rate of 1.5C, meaning they can safely provide a lot of power quickly. But in most cases, you won’t need that much power. Usually, they run at less than 1C or around 0.5C. When you do need a lot of power, like when running many appliances at once, Greenrich batteries can handle it without shutting down. When running fewer appliances, they operate smoothly. Even when the power demand goes up and down, like when you turn on an air conditioner, Greenrich batteries stay reliable and don’t overload. Tests show that using the batteries at high power for short times doesn’t significantly shorten their life. So, just like a Mercedes-Benz gives you a great driving experience at different speeds, Greenrich batteries give you reliable performance in all kinds of power situations.

Statement: Addressing Misconceptions About Our 1.5C Battery for Residential Solar Energy Storage We have recently become aware of claims that Greenrich battery, particularly our signature 1.5C battery, are unsuitable and unfit for the residential solar energy storage market. We would like to refute these statements with solid facts supported by our years of dedicated research and experience in this field, and to ease these rumors. The circulating misbelief about the detrimental effects of 1.5C charging and discharging, leading to the degradation of battery performance and lifespan, can be easily addressed. The key factor that causes the decrease in cell cycle life is the excessive heat generated during charging and discharging, leading to high temperatures of the battery cell. Therefore, the solution is straightforward—either reduce the heat generated during the charging and discharging process, or increase the efficiency of heat dissipation. By doing so, the cell cycle life of batteries with higher discharge rates, such as our 1.5C batteries, can be easily maintained. Addressing our solutions in turn, it is true that certain battery cells are only suited to deliver low currents because of their high internal resistance, which leads to the generation of excessive heat when forced to run at a high current. Imagine electrons as cars on a road: forcing cars to drive fast on a narrow road would be dangerous and reckless, as the road is designed for slow speeds. However, driving at higher speeds on a highway would not be a problem. The same principle applies to a cell. Forcing a 0.5C cell to run at 1.5C would surely cause overheating and degradation of battery performance and lifespan. However, if the cell is designed, with adequate, backed-up research, to be of low internal resistance—such as our 1.5C cells—it can run on high currents without producing excessive heat, thus solving the problem of defective, malfunctioning cells. Moreover, regarding heat dissipation, please refer to the table below comparing the specifics of cells from different companies, which compares the surface areas of battery cells for every wattage generated, for the same discharge rate: Cell Model Company-E 4.6Ah Company-A 63Ah Company-B 280Ah Cell Form Factor Cylindrical Prismatic Prismatic Capacity (Ah) 4.6 63 280 Surface Area/Power (mm²/W) 74 42 16 As shown, the 1.5C battery adopts a 4.6Ah cylindrical cell, which provides a sufficiently larger surface area for heat dissipation compared to other energy storage batteries that use a prismatic cell. Our 1.5C cells are able to maintain a significantly low temperature during the charging and discharging process, ensuring a prolonged cell cycle life. Therefore, by selecting the right products and cells for your home energy storage, a 1.5C discharge with 6000 cycles is certainly possible and not overcommitted. We remain committed to providing reliable, high-quality energy storage solutions and appreciate your continued trust in our products. and welcome all to join the discussion about Facts of lithium battery, including life span, safety, etc..

thanks. it make sense

it is normal. no worry about that.

HI, this is display problem caused by communication between LUX inverter and BMS. you can upgrade the BMS firmware to solve the problem. but if you don't upgrade, it is NOT effect the performance of battery and inverter.

6000+

we can Provide

Hi, the cable between Battery and inverter are needed. but it "hide" inside.

10 years proformance warranty. more than 6000 cycles. DOD 95%

HI, Dutchzan the Greenwich has issued the updated firmware of BMS, now it shows all capacity of power bank (if you have more 1 battery). but old version of firmware (shows 50AH) is not effected any performance of battery.

Greenrich UP3686 has 3.68Kwh capacity, and can supply maximum 5Kw power constantly. You have 8Kw inverter, I think it is Better you use 2 x greenrich Up3686. It allows you use Full capacity of inverter, eg 8Kw at backup mode. You may contact me for setting manual

Some information about Greenrich UP3686 with 8KW inverter 1. Greenrich (Batterich) UP3686 has 3.68KWH capacity, and output Power can be discharged (115A) up to 5KW per battery. 2.if you want to use Greenrich UP3686 with 8KW inverter, you may use 2 batteries, and connect to Bus Bar. you can draw 8KW in full. 3. application of 24KW （3 X 8KW） inverter with 6 Greenrich UP3686 as attached. Please feel free to contact me for any further information.
