Lithium battery module SAJ BU3-TV2 PRO + Base | High modular voltage

SAJ BU3-TV2 Pro Based: 3,12KWh modular storage, cableless stacking connection and smart DC / DC optimizer

Increasing the energy independence rate in a home requires high performance storage capable of capturing surpluses of solar production to free them overnight or from network failures. The system SAJ BU3-TV2 Pro of 3,12 kWh revolutionize domestic storage by eradicating complex and dangerous direct current wired between cells, betting on a clean, minimalistic and safe vertical physical structure that includes its own soil stabilization base.

CC / DC optimizer by block and stackable connectivity without cables

The great technological innovation of the BU3-TV2 PRO module is that each block incorporates its own cC / CC optimizer integrated individually. In conventional high voltage lithium systems, connect modules of different ages or with different states of degradation penalizes the yield of the whole set. Thanks to the optimizer of SAJ, Each unit manages its loading and unloading in isolation, which allows you to expand the storage capacity of your home in the future by adding new blocks regardless of the wear of the above. This product leads our catalog specialized in batteries stationaryDue to its modularity.

The physical installation of this pack is extremely simple thanks to the inclusion of the Reinforced floor. The accumulator module is on the basis and is coupled vertically by means of a system of connection plug-in Plug & Play direct. The power and communication electrical connections are totally hidden internally after adjusting the anchors of your chassis, reducing the aesthetic disorder in the house. To control the load and unloading flows of this cell block, your coupling is required with the upper control electronics of the brand, available in our section of inverters hybrid single-phase and three-phase.

Advanced security, self-holding and compact chassis IP65

The durability and tranquility of the user are shielded thanks to the chemistry of Lithium Ferrophosphate (LifePO4), recognized worldwide by your thermal stability against short circuits. In addition, the BU3-TV2 PRO module implements a integrated Automatic AutoCasement System and an internal fire protection cell, allowing the team to operate without loss of efficiency even in garages or exterior rooms exposed to extreme winters. Physically, it has an elegant design with only 170 mm thick that is mimous with any wall. If you are going to deploy more solar modules on your roof to supply this accumulation bank, we suggest you secure the firmly against adverse weather conditions using our structures for of reinforced extruded aluminum.

Frequently Asked Questions (FAQ)

1. What actual benefit does the CC / CC optimizer provide integrated in the BU3-TV2 Pro module? The individual CC / CC optimizer allows each 3.12 kWh module to work independently. Thanks to this, if in 3 or 4 years you want to expand the capacity of your storage system, you can buy and stack a new module directly on the old ones without the difference of wear or degradation penalize the performance of the photovoltaic system.
2. What is the use of the basis that is included in this pack? The Base is the lower structural support that is placed directly on the ground. It serves to receive the first battery module perfectly level, supporting the weight of the stackable assembly and isolating the electronic components of the soil moisture, guaranteeing a rigid and safe fixation against the wall.
3. Do you require hoses or direct current cables to connect to inverter? Not between the battery modules. The BU3-TV2 PRO series employs a vertical plug-in clip-connection design. Each battery fits physically on top of each other by internal male-female power and communication connectors, eliminating the presence of external DC cables, which increases visual cleaning and electrical safety of housing.
4. Can this battery be installed in an area of housing prone to cold winters? Yes, it is totally apt thanks to that it incorporates a intelligent internal self-care system. When temperatures fall below the ideal operating range of lithium cells, the battery activates its own internal air conditioning to ensure an excellent load and discharge rate without freezing or energy efficiency losses.
