When it comes to setting up a reliable power backup for your home, office, or small business, the most common question users ask is — How Many 200Ah Batteries Are Needed for a 3kVA Inverter? This is an important factor because the number of batteries determines how long your inverter can supply uninterrupted power during an outage.

In this detailed guide by Lento India, we’ll help you understand the right battery configuration, inverter compatibility, and why Lento batteries are among the best options for 2026.

How Many 200Ah Batteries Are Needed for a 3kVA Inverter?

The number of batteries required depends on whether your inverter is 12V, 24V, or 48V rated.

• For a 12V inverter: 1 × 12V battery (not ideal for 3kVA)
   
• For a 24V inverter: 2 × 12V batteries (connected in series)
   
• For a 48V inverter: 4 × 12V batteries (connected in series)

Most 3kVA inverters from Lento India operate on 48V DC, meaning you need four 12V 200Ah batteries connected in series. This setup ensures optimal voltage and sufficient energy backup for heavy-duty applications such as running multiple appliances, computers, fans, and refrigerators simultaneously.

Understanding 3kVA Inverter Capacity

A 3kVA inverter can handle an approximate load of 2400 watts, depending on the power factor (usually 0.8). This makes it ideal for medium-sized homes and offices. However, the inverter’s performance and backup duration depend largely on the battery capacity, which is why the 200Ah battery is the most recommended choice for this system.

Backup Time Calculation

Here’s a quick way to estimate your inverter’s backup time:

Backup Time (in hours) = (Battery Voltage × Battery Capacity × Number of Batteries × Efficiency) / Load Power

Example calculation:
(12 × 200 × 4 × 0.8) / 2400 = 3.2 hours

This means your 3kVA inverter with four 200Ah batteries will provide around 3–4 hours of backup at full load and up to 6–8 hours with lighter loads.
