Lithium Battery for Inverter in Pakistan

Match the battery to your inverter voltage

• 12V inverters and UPS: 12V 100Ah or 200Ah batteries.
• 24V inverters: 24V 100Ah or 200Ah batteries.
• 48V hybrid inverters: 48V or 51.2V batteries from 5kW to 30kW. See all 48V batteries (48V Lithium Battery).
• High-voltage hybrid inverters: high-voltage modules such as the Pylontech Force H3 only.

A wrong voltage will not work and can damage equipment.

Communication: CAN and RS485

Most 48V batteries here list CAN and RS485. With a communication cable, the inverter reads the battery's state of charge and charge limits, which gives a correct battery percentage and protects the cells. Check that your battery brand is on your inverter's list and select the matching protocol. If your inverter has no lithium communication, it can still run in a voltage-based lithium mode, but settings must be set by hand. Read our compatibility guide (Which Lithium Battery Works With My Inverter?).

Key inverter settings

• Battery type: lithium (or the brand protocol).
• Charge voltage and float: from the battery datasheet.
• Low-voltage cut-off or minimum state of charge: many users keep 10 to 20% in reserve.
• Maximum charge current: within the battery's limit.

See our settings guide (Lithium Battery Settings for Growatt, Deye, Inverex and Knox).

What each size runs on an inverter

• 24V 100Ah (2.56 kWh): 300W for about 7 hours.
• 5kW (5.12 kWh): a 1 ton inverter AC at 1,000W for about 4 hours.
• 10kW (10.24 kWh): 2,000W for about 4 hours.
• 16kW (16.07 kWh): 2,000W for close to 7 hours.

Your inverter's output rating also limits the load: a 3kW inverter cannot run more than about 3,000W, however big the battery.

Buying checklist for an inverter lithium battery

Before you order, go through these points with your inverter manual in hand.

• 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.
• Check the inverter's battery list and the communication cable type (CAN or RS485).

If you change brands later, you may need a different communication cable or protocol setting. Keep the battery's manual and datasheet with the inverter so any installer can find the right values.
