Low Voltage Battery
A8
Compact 8 kWh low-voltage LFP battery with fail-safe protection and flexible capacity expansion.
Product description
Pytes A8 is a compact 51.2 V low-voltage LFP battery with 8 kWh of nominal energy for solar and backup power systems. It delivers 5.12 kW of continuous output, up to 6.7 kW for five seconds, and supports parallel expansion to 16 units. Multi-layer electrical protection, an integrated aerosol fire suppression module, and automatic slave unit addressing make the system safe, reliable, and easy to expand.
