AMVOLT 50 kWh LV Module (LiFePO4)
modular electrical energy storage system with a capacity of 50 kWh
The storage system is prepared for Victron Energy technology as standard. The most common extension is network inverters communicating in AC coupling. The power and communication transfer point of the battery storage system is always clearly defined.

Battery module features
A structurally and design-wise open electrical energy storage system assembled from individual battery cells and standardized electrical components. The module is assembled from the highest quality and safest lithium battery technology available, based on high-capacity ThunderSky Winston LiFeYPo4 power cells in safe 48 V low-voltage modules. The basic 50 kWh module is assembled from 16 pcs TSWB-LYP1000AHC 3.3 V cells.

| Recommended capacity usage (kWh) | 48.00 | Saves battery power and service interventions |
| Nominal voltage (V) | 52.8 | |
| Operating voltage (V) | 49.5 – 55.5 | Set limits in the follow-up system |
| Max. charging current/power (A/kW) | 600/30 | Limited by electrical circuit elements |
| Recommended charging current/power (A/kW) | 500/25 | Saves battery power, power circuit, and service interventions |
| Max. discharging current/power (A/kW) | 600/30 | Limited by electrical circuit elements |
| Recommended discharging current/power (A/kW) | 500/25 | Saves battery power, power circuit, and service interventions |
| Operating temperature during discharge (°C) | -5 to +40 | Positive temperatures are recommended |
| Operating temperature during charging (°C) | 0 to +40 | |
| Cycle life (80% DoD cycle) | More than 7000 | |
| Guaranteed total stored energy (MWh) | 295 | For further specifications, see the warranty conditions |
| Weight of cells (kg) | 656 | Set of 16 pieces for one module |
| Total weight of the module (kg) | 960 | Approximate value – depending on equipment |
| Dimensions of the structure W/H/D (mm) | 2200/1360/790 |
Use of modular electrical energy storage:
- For industrial and residential projects
- For new and existing installations
- For the economic management of electrical energy produced in the facility (ESS, UPS, etc.)
- For cooperation with the distribution network (Peak Shaving, SPOT, etc.)
