Inverex INV-LV-P21-11.8 51.2V 230Ah Lithium Battery Price in Pakistan

The Inverex INV-LV-P21-11.8 is a 10kW-class battery, though its true capacity is 11.8 kWh. It is one 51.2V pack with 230Ah of LiFePO4 cells, built as a floor-standing unit with an IP21 rating, and Inverex rates it for 6,000+ cycles. One big pack means fewer cables and no paralleling of two wall batteries.

Backup time from full: about 33 hours on 2 fans, lights and a fridge (about 300W), about 22 hours on 4 fans, 8 LED lights and a TV (about 450W), and about 11 hours on a 1-ton inverter AC with a fan and lights (about 920W). In practice that means a home can run an AC through a hot night, or ride through a long outage with normal loads. Use the lithium battery for AC page (Lithium Battery for AC) to compare AC-focused options.

Compatibility: it is a 48V-class battery for hybrid and off-grid inverters such as Inverex, Growatt, Knox, Fronus and Deye, including 6kW to 12kW models. A battery this size can take high charge and discharge current, so set the inverter charge current to the value in the datasheet and confirm BMS communication for your inverter model.

Installation: it stands on the floor, so you need a flat, strong spot near the inverter. IP21 means indoor use only, so a store room, garage or utility area that stays dry is ideal. Keep space around it for air flow and use thick DC cable with a proper breaker.

Life and warranty: 6,000+ cycles at one cycle a day is well over 15 years of rated cycles. The warranty period is not published for this model in our data, so ask before ordering.

A note on charging: to refill 11.8 kWh from solar every day you need a decent panel array, roughly 6kW or more in summer, after the daytime load. In winter the inverter can top up from the grid during off-peak hours, so the battery is ready before the evening load-shedding slot.

Who should buy it? Homes with a 6kW or larger solar system, families that run an AC at night, and small offices with computers and lights. If you only run fans and lights, a 5kW battery is enough. If you want more again, the Inverex 16kW model is next. Compare in 10kW batteries (10kW Lithium Battery) and read battery size for solar system (What Size Lithium Battery for My Solar System?).
