Many countries around the world are experiencing power shortages. The main reason is that power is not stable enough. In February 2021, a large-scale snow disaster in Texas caused a power outage of 170,000 residents, and some people even froze to death. However, in the Middle East, due to the lack of electricity caused by the high temperature, some residents have died due to the high temperature. The energy problem is now the biggest problem all around the world. OSM Battery hopes to help customers solve their energy problems by providing them with the right energy storage solution.
OSM Battery 768v 200 kwh high voltage battery systems
The storage of electricity is a product that many countries and people urgently needs. The distributed energy storage high voltage lithium ion battery launched by OSM Battery can provide a concentrated commercial power solution for hotels, restaurants, schools, and villas. The 768V 200kwh energy storage system can provide sufficient power in many scenarios to meet customer demand. It can match PCS with 50KW 100KW power to meet the power supply of various customers. They have successfully delivered more than a dozen sets of such products in Europe and South America. This commercial energy storage system covers some accessories such as EMS, PCS, BMS, etc. For customers, they only need to use solar panel or grids to charge the system. Lots of them like to use the Charge it at night and discharge at peak time to save electricity budget.
Energy storage case
The following pictures are some cases of actual INSTALLATION of OSM Battery storage battery.
100KWH Project in the Czech Republic.
200KWH Project in Ireland
Each battery cluster is high voltage lithium ion battery 768V 100kwh, which can be increased to 200kwh 215kwh according to customer requirements, and the power can be increased continuously.
The advantages of OSM Battery
In the past, for such a system, customers had to purchase batteries, inverter PCS and other components separately. But OSM Battery matched them together. So that, with the energy storage solution, the whole system can be tuned properly. When customer receiving the system, as long as they according to the requirements of the installation, it can be used normally. This saves the customer a lot of unnecessary trouble. At the same time, it also helps customers save money. Since the high voltage battery uses lithium iron phosphate battery, it is safer and more reliable and has a longer service life.
A mature high voltage energy storage solutions like OSM Battery will gradually be favored by more and more users. And they will help more people to solve the problem of electricity shortage. If you are in need of energy storage solution, please feel free to contact us.
What a 768V energy storage system is
A 768 V DC system is built from 240 LiFePO4 cells in series (240 × 3.2 V = 768 V). The capacity is then set by the parallel count, so a 768 V 200 Ah cabinet stores about 153 kWh at nominal voltage. Systems at this voltage exist for one reason: industrial loads and long cable runs, where the current for the same power would otherwise be unmanageable.
DC bus voltages in industrial storage
| DC bus | Series cells (3.2 V) | Current for 100 kW | Typical use |
|---|---|---|---|
| 400 V | 125S | 250 A | Entry industrial, small UPS |
| 440 V | 138S | 227 A | Industrial retrofit |
| 512 V | 160S | 195 A | Commercial and industrial ESS |
| 768 V | 240S | 130 A | Heavy industrial, factories |
The current column is the whole argument for high voltage: the same 100 kW moves at 130 A on a 768 V bus instead of 250 A on a 400 V bus, which nearly halves the cable copper and the I²R loss. The electrical reasoning is set out in high voltage battery systems explained.
Where 768V systems are used
- Manufacturing plants and factories — the demand-charge and peak-shaving case this page describes.
- Industrial parks — PV self-consumption and load shifting across several buildings.
- Heavy UPS — short, high-power discharge with a compact footprint.
- Microgrids — long DC runs from a battery room to the point of use.
Sizing a 768V system
Three numbers define the system: the energy (kWh), which sets the capacity and the number of racks; the power (kW), which sets the C-rate and therefore the cell format and BMS current; and the autonomy (hours), which sizes the energy against the load. For a 200–300 kWh installation a 768 V 200 Ah cabinet is a common building block, expanded by paralleling racks. A 50 kWh class alternative for smaller sites is our custom 512 V 50 kWh ESS battery.
Protection architecture at 768V
At this voltage the protection hardware is as important as the cells. A 768 V pack needs a master BMS supervising many module-level BMUs, main contactors with a pre-charge circuit, continuous insulation-resistance monitoring to earth, and DC-rated fusing because DC arcs do not self-extinguish. The tiering and its components are described in BMS for high voltage lithium batteries.
768V battery FAQs
How many cells are in a 768V battery?
240 LiFePO4 cells in series, since each cell is 3.2 V nominal. The parallel count is then chosen to reach the required amp-hours.
Why use 768V instead of 400V?
To halve the current for the same power, which cuts cable loss and copper size, and to reduce the number of parallel strings needed for a given energy.
What is the capacity of a 768V 200Ah battery?
About 153 kWh at nominal voltage (768 V × 200 Ah). Real usable energy is slightly lower once the depth-of-discharge limit is applied.
