30kW Lithium Battery Price in Pakistan

30kW lithium battery models

• Knox Powerbase 32: 51.2V 628Ah, 32.15 kWh, floor-standing, 8,000 cycles, 5-year warranty.
• Ziewnic Z-Box 30kWh: 51.2V 600Ah, 30.72 kWh, floor-standing. Warranty and cycle ratings are not listed in our specs, so ask before ordering.

Both list CAN and RS485 communication.

What a 30kW battery runs

• Two ACs at 2,000W: about 12.7 hours (Ziewnic) to 13.3 hours (Knox).
• Three ACs at 3,000W: about 8.5 to 9 hours.
• 5,000W office load: about 5 hours.

That covers a large home with three ACs through most of the night, or an office through the evening. Use the backup calculator (Battery Backup Calculator).

One 30kW unit or two 16kW batteries?

One 30kW unit is a single box with one BMS and simpler wiring. Two 16kW batteries (16kW Lithium Battery) give more brand choice, can be bought one at a time, and keep half your storage working if one needs service. Compare the live price of both routes. Either way, your inverter or inverters must be able to charge about 30 kWh in a day, which usually means 10kW or more of solar and inverter capacity.

Installation

A 30kW battery is very heavy. Place it on a strong, level floor in a cool, ventilated room, away from direct sun and water. Use thick cables and a proper DC breaker, and have a trained installer set the charge and cut-off values. See our battery sizing guide (What Size Lithium Battery for My Solar System?).

Buying checklist for a 30kW lithium battery

A 30kW battery is a major purchase for a home or business, so go through these points first.

• Match the battery voltage to your inverter or UPS.
• Check the cycle rating and warranty years; where a value is missing, ask or check the datasheet.
• Keep the invoice and serial number for any warranty claim.
• Set the charge voltage and cut-off from the datasheet, not from memory.
• Install in a cool, ventilated spot, away from direct sun.
• Confirm the battery is on your inverter's list and set the right protocol.
• Make sure your solar array and inverter can refill about 30 kWh in a day.
• Plan the floor spot, the cable route and access for delivery and service.

If your load is mostly daytime, a smaller battery with more panels may serve you better. Size it first with the solar calculator (Solar Calculator).
