  This free-standing storage system on wheels offers a capacity of 25 kWh and is compatible with most 48V/51.2V inverters. It includes an integrated BMS and is designed for floor mounting.

All of the mentioned storage systems feature a long cycle life of over 6,000 charge cycles and come with a 10-year warranty. They are compatible with most common inverters and offer flexible installation options.

What Is the Difference Between a High-Voltage and a Low-Voltage Storage System?

A high-voltage (HV) and a low-voltage (LV) storage system differ primarily in the voltage level at which they operate, as well as their respective properties and applications. Below is a detailed comparison:

1. Operating Voltage

   • High-Voltage Storage
     • Operating voltage: 150 V to over 1,000 V (typically 400–800 V).
     • Lower current at the same power level, resulting in reduced energy losses.
   • Low-Voltage Storage
     • Operating voltage: 12 V to 150 V (typically 48–120 V).
     • Higher current at the same power level, leading to increased energy losses.

2. Design and Components

   • High-Voltage Storage
     • Requires stronger insulation and enhanced safety measures due to higher voltage levels.
     • Typically composed of multiple battery cells connected in series.
   • Low-Voltage Storage
     • Simpler design with lower safety requirements.
     • Often uses parallel-connected cells to achieve higher capacity.

3. Efficiency and Losses

   • High-Voltage Storage
     • Greater efficiency due to lower current and reduced line losses.
     • Ideal for applications with high energy flows, such as large PV systems.
   • Low-Voltage Storage
     • Higher energy losses due to higher current levels.
     • Sufficient for small-scale applications.

4. Safety

   • High-Voltage Storage
     • Potentially more dangerous due to the high voltages, requiring special safety mechanisms.
   • Low-Voltage Storage
     • Safer to handle because of lower voltage levels. Preferred for home use or DIY projects.

5. Applications

   • High-Voltage Storage
     • Large PV systems or industrial applications.
     • Electric vehicles.
   • • Small-scale PV systems for households.
     • Stand-alone solutions, such as garden setups or backup systems.
