High Voltage Lithium Batteries

High Voltage Lithium Batteries

High voltage or HV batteries are designed to work in grid-connected installations with demanding storage needs. They have a modular format so they are easily scalable. Depending on the model of high voltage or HV lithium batteries, it is recommended that they are installed inside a rack or structure so that they work safely when working together. In this way, their useful life is extended.

High-voltage solar batteries are energy storage equipment that operate at voltages above 100V, typically between 120V and 600V, depending on the configuration and brand. Unlike low-voltage solar panel batteries, which typically operate in the 12V, 24V or 48V range, a high-voltage battery is designed to be integrated with hybrid inverters for self-consumption, improving the conversion and efficient use of stored energy.

Its modular architecture allows for scalability, which means that more high-voltage batteries can be added as consumption needs change, ensuring a stable and efficient power supply. In addition, the high-voltage batteries are optimised for deep discharge and a longer cycle life, which translates into a profitable long-term investment.

High Voltage Batteries: Characteristics

High voltage lithium batteries, also known as HV batteries, are designed to work at a higher voltage than the 48V offered by other batteries on the market. They are prepared to work in very demanding photovoltaic installations that have a hybrid inverter for self-consumption. The most common installations are 12V, 24V or 48V.

There are inverter brands that only manufacture high voltage inverters. They are very attractive for large-scale grid connection installations, as they can be easily adapted to the home's system. If the energy needs are high, this type of installation is an excellent option and the trend of the future.

HV batteries require smaller cable cross-section than conventional lithium batteries, which saves on wiring and simplifies connections and installation. If you have any doubts, please contact us at [email protected].

The problem with the installation of high voltage batteries is the limitation of the battery power, although this is more a problem of the lithium battery technology than HV.

Unlike other batteries on the market (open lead acid, AGM, GEL, stationary, etc.), high-voltage lithium batteries can be connected in parallel or in series.

One of the fundamental characteristics of these batteries is their easy compatibility and expandability with the rest of the elements of the photovoltaic installation.

Advantages of high voltage lithium batteries

Increased Energy Efficiency
High-voltage batteries reduce loss during energy conversion and storage, which means better utilisation of every kilowatt-hour (kWh) generated by solar photovoltaic panels. Thanks to their lower internal resistance, high-voltage lithium batteries allow for faster charging and discharging, optimising the efficiency of the solar system.

Expandable Storage Capacity
Many HV batteries have a modular design that allows capacity to be increased according to consumption needs. This makes an hv battery ideal for both small solar-powered homes and large commercial or industrial installations.

Compatible with Hybrid Inverters for Self-Consumption
A high voltage byd battery is designed to work with hybrid solar inverters, allowing for better management of stored renewable energy and thus maximising PV self-consumption. Some hv battery models include intelligent management systems (BMS) that optimise performance and extend the life of the system.

Longer Life and Load Cycles
A high-voltage battery, especially those with lithium-ion technology, offers a much longer service life compared to traditional lead-acid batteries. Many high-voltage batteries can reach more than 6,000 charge cycles, ensuring optimal operation for more than 10 to 15 years.

Energy Autonomy and Reduced Grid Dependence
With a high voltage lithium battery, you can store surplus energy generated during the day for use at night or at times when there is less solar production. This reduces the need to consume electricity from the grid, thus lowering electricity bill costs.

Security and Stability
High-voltage lithium batteries are equipped with advanced safety systems, including overcharge, over-discharge, short-circuit and overheat protection. In addition, most high-voltage batteries feature real-time monitoring, allowing you to monitor their operation from a mobile app or energy management software.

Applications of high voltage lithium batteries

Self-consumption batteries are ideal for users looking for efficient, high-performance energy storage. Take a look at our self-consumption battery kits; these hv batteries are especially recommended for:

• Homes with photovoltaic solar energy: If your home has a high demand for electricity, installing self-consumption domestic batteries will allow you to make the most of solar energy at home.
• Companies and businesses: Businesses with solar photovoltaic installations can significantly reduce their electricity costs and increase their energy independence if they install batteries for self-consumption solar panels.
• Industry and large-scale installations: For larger scale installations, self-consumption batteries offer a robust and scalable solution to ensure a stable solar power supply.
• Users with PV self-consumption systems: If you have a hybrid inverter and want to maximise your self-consumption with batteries, a high-voltage battery is the ideal choice.

Choosing the best battery for self-consumption

When choosing a solar self-consumption battery, it is important to consider several key factors:

• Energy storage capacity (kWh): Determines the amount of energy that the self-consumption battery can store and will depend on the energy consumption of your home or business.
• Compatibility with hybrid inverters: Make sure that the high-voltage lithium-ion battery is compatible with your solar inverter for optimal integration into the PV system.
• Type of technology: Self-consumption photovoltaic batteries are the most recommended due to their high efficiency, long life and low maintenance.
• Scalability: If you want to increase your energy storage capacity in the future, choose a modular high-voltage byd battery that allows for expansion.
• Warranty and life cycles: Opt for high voltage batteries with warranties of at least 10 years and more than 5,000 - 6,000 charge and discharge cycles.
