 Technical characteristics Lithium Battery BYD B-Box HVS Premium 12.8
 The BYD B-Box HVS Premium 12.8kWh Lithium Battery from the Chinese manufacturer BYD is a type of high-voltage lithium accumulator, which replaces the previous HV range. The new B-Box Premium HVS range represents an improvement of very remarkable characteristics for this accumulator model. The manufacturing technology of the BYD B-Box HVS Premium 12.8kWh Lithium Battery is Cobalt-free LiFePo (lithium ferrophosphate battery).
 This 12.8kWh B-Box model has the lower support, five accumulator modules and the BMS in its upper part that acts as a battery manager. This gives it the following technical characteristics:
 Usable energy: 12.8kWh.
 Number of modules: 5.
 Nominal voltage: 512V.
 Operating voltage range: 400 to 600V.
 Maximum output current: 25A.
 Peak output current: 50A for 5 seconds.
 Weight: 205Kg.
 This model is the highest capacity in the HVS Premium range as it has 5 modules. Depending on the system, we can install up to 3 groups in parallel to obtain a greater accumulation capacity.
 The BYD B-Box HVS Premium 12.8kWh Lithium Battery is compatible with the market's leading brands of both single-phase and three-phase inverters. Its working voltage is high voltage, but it is also prepared to work in isolation and self-consumption, depending on the type of inverter with which it is accompanied. The HVS range consists of 2 to 5 modules that are connected in series and allow us to configure a battery between 5.12 and 12.8kWh. Initially it is possible to directly connect up to 3 HVS model towers in parallel for a total capacity of 38.4kWh, so we will have great flexibility for our present and future projects. The previous HV range, in addition to this Battery-Box Premium HVS, is also divided into the Battery-Box Premium HVM models, with a series of different characteristics such as a higher module stacking capacity and a higher discharge rate, among other differences.
 
 Installation Lithium Battery BYD B-Box HVS Premium 12.8kWh
 One of the great advantages of the BYD B-Box HVS Premium 12.8kWh Lithium Battery is that it can be installed in a stackable way, without the need for any cabinet and without wiring between the modules. It can be started from an installation with 2 modules and progressively expand according to our needs. It will only be necessary to take into account that the inverter is compatible with the extensions since with each module we will increase the voltage of the battery bank.
