The core highlight of Enerkey's household storage products is the use of low-voltage 280Ah battery + DC/DC boost solution, equipped with a battery pack-level DC/DC module (BMS active balancing), and the balancing current can reach 5A,

which helps to increase the product life by 2-3 years, and users can flexibly expand capacity and power. In addition, the high-voltage stacked household storage battery is also equipped with a module-level DC/DC.

On the one hand, applying 280Ah low-voltage batteries to household storage and then boosting them through DC/DC modules reduces the cost of batteries,

slows down the rate of battery capacity decay, and increases the cycle life of household storage systems; on the other hand, if the battery needs to be expanded later,

adding a new Pack to the original household storage battery system can also be easily achieved. As the operation time of the energy storage system increases,

there will inevitably be a situation where the battery voltage and capacity differences are getting bigger and bigger. Battery decay is irreversible.

Faced with a series of problems such as capacity decay, life dive, safety discount, and energy efficiency reduction, the battery level is mainly upgraded through pre-lithiation,

high temperature resistance and other technologies, and the system level can add DC/DC modules. Enerkey Power believes that for energy storage systems, BMS active balancing can produce good results,

but the stability still needs to be improved. The equalizer/optimizer has stronger balancing capabilities, but there is still room for improvement in cost and stability. Only by finding an appropriate scenario can the greatest effect be achieved.

Wiring Diagram

EK-16S2EB supports cascading use, and at least one battery between every two equalizers is the "common end of energy exchange". The following uses the 32S as an example to describe how to install and connect cables:

Notice:
1.When used in cascade, there is at least one "energy exchange commonend" between every two equalizers. When welding, please note whetherthe connection here is correct.

2.During cascading use, please check whether the wiring is wrongrepeatedly.lf it cannot be used after connection, please contactafter-sales personnel to consult the corresponding cascade diagram.
