Crown Solar Energy Elecktra 5.12kWh IP21 Lithium Battery 51.2V 100Ah

The latest Crown Solar Energy Elecktra 5.12kWh IP21 Lithium Battery 51.2V 100Ah price in Pakistan is Rs. 238,000/- updated on August 31, 2026.

Overview:

The Crown Solar Energy Elecktra 5.12kWh IP21 Lithium Battery (51.2V 100Ah, official model CSE-ESS-51.2V100Ah) is the 48V-platform counterpart to the 25.6V Electra Boost range, built for residential and commercial solar systems that run on a higher-voltage battery bus. It delivers 5.12kWh of rated capacity with 4.6kWh usable, reflecting a conservative usable-capacity rating rather than the full nameplate figure.

Operating voltage spans 40V–57.6V with a narrower 44.8V–56.8V recommended range for typical day-to-day charge/discharge cycling, and the recommended charge/discharge current is 50A — sensible headroom for a 100Ah pack without pushing the cells harder than necessary on a daily basis. Like the rest of Crown’s lithium range, it uses LiFePO₄ (LFP) chemistry for safety and long service life.

The IP21 rating means this unit is designed for indoor or otherwise protected installation rather than direct outdoor exposure, consistent with the same IP21 rating used across Crown’s Yorker inverter range — a sensible pairing for indoor solar storage setups. Crown backs the Elecktra range with a 10-year replacement warranty.
