Crown CMLB-51.2 230Ah Lithium Battery Price in Pakistan

The Crown CMLB-51.2 230Ah is a 51.2V lithium iron phosphate battery with 230Ah of capacity. That works out to 11.77 kWh, which places it in the "10kw lithium battery" class people search for, with a bit more storage than the usual 10.24 kWh (200Ah) models. It is floor-standing, so it needs a level, dry floor in an inverter room, store or garage.

It is the big brother of the Crown CMLB-51.2 100Ah. Both run at 51.2V, but the 230Ah model stores about 2.3 times the energy of the 100Ah wall unit (11.77 kWh against 5.12 kWh) and stands on the floor instead of the wall. Neither has a published cycle rating or warranty period on our sheet. Against the Crown Elektra 5.12 Pro, which lists 6,000+ cycles and a 10-year warranty, the CMLB 230Ah wins on capacity but not on paperwork, so ask for its terms before ordering.

Backup from a full charge: - 2 fans + lights + fridge (about 300W): about 32 hours - 4 fans + 8 LED lights + TV (about 450W): about 22 hours - 1-ton inverter AC + fan + lights (about 920W): about 11 hours

Even a 1.5kW load (an AC plus a fridge, fans and lights) gets about 6 hours by the standard formula. Check your own numbers on the backup calculator (Battery Backup Calculator). The CMLB-51.2 230Ah is for 48V hybrid and off-grid inverters such as Growatt, Inverex, Knox, Fronus and Deye. A battery of this size can feed a large inverter, but check the datasheet's maximum charge and discharge current against your inverter and use cables and breakers sized for that current. Set lithium mode and the Crown datasheet voltages. To size your panels so this much storage refills on a sunny day, use the solar calculator (Solar Calculator).

Place it indoors on a firm floor in a cool, ventilated room. No IP rating is listed, so keep it away from water and direct sun. A 230Ah unit is heavy, so plan where it will stand before delivery. LiFePO4 handles deep daily cycling well, but Crown has not given us its cycle or warranty figures, so collect the datasheet and warranty card.

Buy it if you want AC at night or long backup for a large family home in a single cabinet. If you need still more, see the 16kW batteries (16kW Lithium Battery).
