The stackable V-TAC system of 20,48kwh It has been designed for households and companies that do not want commitments in their power supply. When it works in a range of High voltage (204,8v), this system minimizes energy transport losses and optimizes the performance of Inverters solar, allowing to manage demand peaks with greater solvency than conventional low voltage systems.

With a Useful capacity of 16.38kwh About 20,48kwh nominal, and a recommended load / unloading current of 40a, this system offers an optimal balance between performance and longevity of cells.

Modular design: Grow with your needs

The great advantage of this system is its architecture Stackable (stackable). It consists of a base (Oh-basedand Four modules OH-5K of 5,12kwh everyone who is mounted vertically, occupying just 590 x 420 mm of soil This structure not only facilitates a clean and no-wireless installation, but it allows expanding capacity to 40,96kwh Adding additional modules (up to 8 units in series), adapting perfectly to the evolution of your Photovoltaic Solar Kit.

Technology LIFEPO4: Safety and Longevity

On Tienda Solar We bet for maximum security. The cells of Iron and lithium phosphate (LifePO4) They guarantee a stable chemistry that reduces the risk of fire for overheating. With a useful life ≥6000 70% EOL cycles (Tested at 25 ° C, 0.5c / 0.5c), this system ensures many years of daily operation. Your smart BMS includes Soft start (Soft Start), Automatic rolling cells, Protection against overload and overdrops, overcurrent protection, short-circuit and thermal protection, integrating with any lithium battery Additional you want to add to the system.

Maximum compatibility and online monitoring

This system is a universal solution. Thanks to its Communication Protocol Can, it is fully compatible with leading brands like Deye, GoodWe, Solis, Sofar, Afore, Koyoe, Megarevo and Atess. In addition, it allows real-time monitoring of tension, current and temperature of the system by means of a algorithm smart SOC, with online updates that facilitate remote maintenance and ensure that your system always has the latest load and download optimizations for your solar panels.

High-voltage Box Control

The system incorporates the control unit OHS-hv100, a high-voltage battery control cluster with a range of Operation of 120 to 750VDC, a 40A cargo nominal current / discharge current and one Maximum current of up to 50a, with protection Ip65 Also in this unit. If your installation also requires robust supports, in the store you will find solar adapted to any type of cover or soil.

Frequently Asked Questions (FAQ)

1. What is the difference between this system and a 48V battery in Tienda Solar?
This system works High voltage (204,8v). High voltage systems are more efficient in the CC energy conversion to AC, generate less losses and allow lower-section cables, the preferred option being for commercial and residential installations of greater energy requirement.

2. Can I install it on the outside?
Yes, both the battery modules and the control unit have protection Ip65, what makes them hermetic dust and rain resistant. However, in Tienda Solar We recommend avoiding direct exposure to the sun to optimize thermal performance, always respecting the working temperature range indicated by the manufacturer.

3. How many modules can I be stacked and until what capacity can I expand the system?
This standard kit is configured with 4 modules (20.48kwh), but the design allows to expand up 8 modules in series, reaching the 40,96kwh in a single tower, always within the tension limits supported by your hybrid Inverter.

4. With what inverters Is this system compatible?
It is compatible with leading brands of the sector as Deye, GoodWe, Solis, Sofar, Afore, Koyoe, Megarevo and Atess, thanks to your communication protocol Can standard.

5. What current does the high voltage control unit support?
Unit OHS-hv100 admits a 40A nominal current and one Maximum current of 50a, with a range of operation 120 to 750Vdc, Adapting to different system configurations.

6. Do I need to hire a professional installer?
Given the weight of the system (207 kg in its 20.48kWh configuration) and the need to correctly configure the high-range voltage with the inverter, in Tienda Solar We recommend that the installation perform a qualified professional to guarantee the safety and validity of the guarantee.
