If you’re planning to install a 5kVA inverter with battery, you’re probably wondering how many solar panels are required to make the system efficient and reliable. Let’s break it down step by step and understand how to size your solar power system properly with Lento India, one of the leading manufacturers of inverters, batteries, and solar solutions.

How Many Solar Panels Are Needed for a 5kVA Inverter with Battery?

The number of solar panels you need for a 5kVA inverter depends on the panel wattage and your total energy consumption. Typically, a 5kVA inverter requires between 8 to 13 solar panels rated at 300 to 400 watts each.

Here’s a simple example:

• 1 panel = 400W
   
• 5kVA = 5000W
   
• 5000 ÷ 400 = 12.5

So, you’ll need 13 solar panels of 400W capacity for a 5kVA inverter.

If you are using 300W solar panels, the number increases to 17 panels to achieve equivalent capacity.

The combination of solar panels and batteries helps you store excess energy for night-time or cloudy days, making your home or business power-independent. Factors like sunlight hours, inverter efficiency, and battery type slightly influence the final configuration, but this setup ensures efficient energy generation and long-lasting performance.

Battery Configuration for a 5kVA Inverter

A 5kVA inverter with battery generally operates on 48V DC, meaning you’ll need four 12V batteries connected in series.

To get the best performance, Lento recommends 12V 200Ah tubular batteries or SMF batteries that ensure long life and deep discharge cycles.

• Tubular Battery (C10 – 200Ah, 220Ah, 240Ah): Best suited for heavy-duty applications, offering higher backup capacity and longer life span.
   
• SMF Battery (12V 100Ah or 150Ah): Compact, sealed, and maintenance-free, ideal for space-constrained installations.

These batteries store solar power effectively and provide uninterrupted backup for essential appliances like lights, fans, refrigerators, and computers.

Understanding How the 5kVA Hybrid Inverter Works

The hybrid inverter combines the functions of both solar inverters and battery inverters, allowing smart power management between solar panels, battery storage, and the utility grid.

Key functions of a hybrid inverter include:

• DC-to-AC and AC-to-DC conversion: Converts DC electricity from solar panels into AC power for home use and stores extra energy into batteries.
   
• Real-time monitoring: Displays system performance through LCD or smartphone app.
   
• Power optimization with MPPT: Extracts maximum power from solar panels even in variable weather conditions.
   
• Seamless switching: Automatically shifts between solar, battery, and grid power based on availability.

Lento India’s 5kVA Hybrid Inverter offers DSP-based technology, high surge power, and protection features against over-voltage, short circuits, and polarity reversal—making it a reliable choice for both homes and industries.
