AMVOLT 14 kWh LV Energy Box

AMVOLT 14 kWh LV Energy Box

Scalable compact Energy Box from the Czech Republic.

AMVOLT's technical philosophy is to build open storage systems in the Czech Republic from individual battery cells and interchangeable standardized components. This significantly extends the life of the entire storage system compared to the now widespread closed, non-repairable battery boxes and drawers.

The AMVOLT LV Energy Boxes are intentionally designed to allow the customer to have the option of any future expansion, modification or service without depending on the AMVOLT itself.

AMVOLT LV Energy Box is designed for 16 pieces of ELERIX EX L280 LiFePO4 cells with an operating voltage of 51.2 V. Battery cells are manufactured according to EN IEC 62619 and have been tested in accordance with this standard (tested by TÜV Rheinland).

Pre-configured solar water heating set now in our offer

Pre-configured solar water heating set now in our offer

This simple but effective water heating set includes the GF-SUN-2000G2 grid tied inverter and ELERIX solar panels with a maximum output of 410 Wp. It stands out for its excellent price/performance ratio and ease of installation.

The kit is recommended for use in cottages and smaller summer houses where there is a low level of electricity supply, an overloaded power grid or limited possibilities to use other sources for water heating.

The SUN 2000 VA line inverter with limiter (GTIL) is connected only to the boiler electrical circuit and operates only when the boiler is heating water (if its heating is on). This always draws power from the entire boiler so that no overflows to the mains (or indication overflows) can occur. In the event of a failure of the system components (boiler, inverter contactor), the system is protected in the no-current mode by an inverter overflow limiter.

    Everything you need to build your own battery energy storage

    Everything you need to build your own battery energy storage

    By assembling a battery storage system from ELERIX cells, you gain an undeniable advantage over battery "black boxes" from dubious manufacturers.

    The individual battery cells are interchangeable, they are not welded together in any way. All components can be easily replaced or repaired thanks to the availability of spare parts.

    Our battery packs are therefore fully repairable, which means that we want to realistically extend the lifetime of entire storage systems and thus save the environment.

    With ELERIX kits you do not have to be limited by predefined dimensions and battery settings. Build your own battery to suit your needs! Take a closer look at the kits!

This gives them a number of advantages, such as lower electrical resistance and associated better performance. Making the individual cells smaller also reduces the risk of damage due to cracking. By dividing the panel into two halves, the upper part operates independently of the lower part, which is particularly appreciated when one half is shaded.

    NEW AMETEK Magnetic Latching Contactors are already in stock

    What it is for? Latched Low Voltage Disconnect Contactor is more compact than traditional low voltage disconnects. The permanent magnet holds the contact closed. Momentary power to the coil closes the contact, while a momentary reverse power signal to the coil opens the contact. It also uses the same bus bars available on traditional electrically held contactors.

    What are the other benefits that AMETEK brings to the table?

    - Coil heat is eliminated

    - Reduces the need for redundant power control

    - Designed to remain closed for 20 years

    - Fail-safe - contacts open or close only when an appropriate signal is applied

    Shingled technology - Video presentation

    Shingled technology - Video presentation

    What makes the new Elerix Shingled technology so great?

    1. The cells are made of strips that overlap. There are no more idle gaps, so the module has a larger active area which increases the power output and module efficiency.

    2. The Elerix Shingled modules use an electrically conductive adhesive that connects the silicon strips. This reduces the need for the busbars.

    3. And they look nicer

    "The Corset"

    Do you need to use the cells in parallel to reach higher capacity?

    The CORSET by GWL is a metal holder for lithium cells to keep them tight together in a desired shape or configuration.The CORSET is used to support a group of cells and make them into a firm pack. Unlike a customized battery holder, the corset is made of simple, industrially available components and allows to be disassembled and reused.

    The CORSET mounts the cells together, holds them tightly and also protects the cells against bulging or swelling. Additionally, the CORSET protects the cells against mechanical damage.

    The beauty amongst all solar panels - Full Black

    The beauty amongst all solar panels - Full Black

    Have you ever looked at your roof and told yourself: "Great! Now I'm energy self-sufficient...but I wish it looked better on my roof" ?

    Our elegant full black version of a solar panel could help you out in this case and get you rid of this thought.

    With a combination of the black color of cells (mono), black frame and black cover of busbars, the solar panel makes an attractive full black design which looks great on a house roof and gives the panel a nice “neutral” look.

    The full black design of panels is then the opposite
    of the classic poly design, where the poly cells, on the other hand, create a blue-ish look.

    Well, just look at the picture, where you can spot the differences :)

    How toxic can be the damaged Lithium cells? We test it.
    We used the fire ax to harm the shell of the cell to cause damage like a short circuit. Catch the released steam, measure the pressure and composition of all gas emissions. The toxic gas hydrogen fluoride is the most dangerous in this case and it is necessary to ensure rapid dilution with fresh air.
