Inverex INV 5.1kW IP21 48 Voltage Lithium Battery

The latest Inverex INV 5.1kW IP21 48 Voltage Lithium Battery price in Pakistan is Rs. 285,000/- updated on August 30, 2026.

Overview:

The Inverex INV 5.1kW IP21 48 Voltage Lithium Battery (INV-LV-IP21 5.1) is the entry point of the IP21 Power Wall series, using the same safety-focused LiFePO₄ chemistry as its 11.8kWh and 16kWh siblings. It delivers 5.12kWh of total energy at 51.2V nominal with a 100Ah capacity, supporting a 1C discharge rate for demanding household loads — enough to run most residential appliance combinations, including inductive loads like fridges and pumps that draw a startup surge.

An integrated smart BMS monitors cells in real time to guard against over-charging, over-discharging and thermal faults, which is what LiFePO₄ chemistry’s reputation for safety actually depends on in practice — the cell chemistry itself is stable, but the BMS is what prevents individual cell imbalance from becoming a real problem over years of cycling. The unit auto-networks without DIP switches for quick installation, removing a common source of setup error on multi-unit installs.

Up to 16 units can be combined for larger banks, with cycle life rated at 6,000–8,000+ cycles at 80% DoD — translating to roughly 10–15 years of typical daily use, which lines up with the expected service life of the solar inverter and panel system it would typically be paired with.

Key Features:

• 51.2V nominal, 100Ah capacity, 5.12kWh total energy
• LiFePO₄ (Lithium Iron Phosphate) chemistry — among the safest, most stable lithium technologies
• 1C discharge rate for demanding household loads, including inductive startup surges
• Integrated smart BMS with real-time cell monitoring
• Protection against over-charging, over-discharging and thermal faults
• Rated for 6,000–8,000+ cycles at 80% Depth of Discharge (roughly 10–15 years of daily use)
• Auto-networking — no DIP switches required for setup
• Scalable up to 16 units for larger battery banks
• IP21 ingress protection, designed for indoor installation
