If you’re considering buying a 3.5kVA inverter in Nigeria, you can expect to spend between ₦650,000 and ₦750,000 in 2025. This price range reflects the average market value for quality pure sine wave models for home and small business use.
It’s important to remember that this figure covers the inverter alone. Batteries, solar panels, and installation costs are additional expenses that can significantly increase the total investment.
The exact price depends on several factors, including brand, whether it’s solar-compatible, and its features (such as LCD displays, inbuilt charge controllers, or hybrid functionality).
Please understand that these prices are not fixed as they fluctuate due to exchange rates, availability, and location.
What Can a 3.5kVA Inverter Power?
A 3.5kVA inverter load capacity is well-suited for powering various household and small office appliances. It strikes a good balance between capacity and affordability, making it ideal for:
- LED or energy-saving light bulbs (up to 10-15 points)
- Standing or ceiling fans (2-4 units)
- Televisions and decoders
- Laptops, modems, and small printers
- Refrigerators and small freezers
- Charging points for phones and devices
For a typical Nigerian household or a small business such as a boutique, pharmacy, POS shop, or small office, a 3.5kVA inverter can handle all essential electronics, especially when combined with the right battery bank.
However, it is not advisable to use it for heavy appliances like air conditioners, water heaters, or industrial machines, unless the load has been carefully calculated and balanced. The inverter is best suited for loads below 2,800 watts, giving you enough room for daily essentials without overloading the system.
Factors That Affect the Price of a 3.5kVA Inverter
Not all 3.5kVA inverters are created equal. The price tag is influenced by several variables, which buyers should understand before making a purchase:
Brand Reputation
Established inverter brands with a proven track record usually cost more due to their reliability, customer support, and long-term durability.
Inverter Type
- Pure sine wave inverters are more expensive but safer for sensitive electronics.
- Modified sine wave inverters are cheaper but not ideal for long-term or delicate use.
- Hybrid inverters (which combine an inverter, charge controller, and sometimes battery management systems) come at a premium price.
Battery Voltage Compatibility
Some 3.5kVA inverters operate on 24V systems (requiring two batteries), while others use 48V setups (four batteries). Higher voltage systems may cost more but offer better efficiency and longer runtime.
Integrated Features
Advanced features like LCD screens, remote monitoring, built-in solar charge controllers, or automatic switchovers add to the cost.
Installation and Accessories
Your final cost will also depend on whether you’re buying just the inverter or a full solar or backup package with batteries, mounting kits, and professional installation.
Location and Availability
Prices may be slightly higher in regions where inverter products are unavailable or where shipping logistics raise distribution costs.

Battery and Installation Costs: What Else Should You Budget For?
While the inverter is a key part of your power setup, it’s only one piece of the puzzle. To get a 3.5kVA inverter fully operational, you must budget for a few essential components and services. These include:
- Batteries
A 3.5kVA inverter on a 24V system will require two 12V batteries connected in series. For longer backup time and better performance, 200Ah batteries are typically recommended. Battery costs vary widely depending on brand and type, but in 2025, one 12V 200Ah battery may cost ₦200,000 to ₦300,000, so expect to spend ₦400,000 to ₦600,000 for batteries alone.
- Battery Rack
A good-quality battery rack helps organise your batteries and ensures safety. A sturdy rack for two to four batteries can cost ₦25,000 to ₦50,000.
- Cables and Wiring
You’ll need DC cables, AC cables, fuses, breakers, and connectors for proper wiring. Budget ₦20,000 to ₦40,000 for quality wiring and protection materials.
- Charge Controller (if using solar)
If you plan to integrate solar panels into your setup and your inverter doesn’t already include a charge controller, you’ll need one. Prices vary by type and size, but a good MPPT controller for a 3.5kVA system may cost ₦70,000 to ₦120,000.
- Installation Labor
Hiring a professional installer is essential for safety and performance. Depending on location and complexity, professional installation services cannot be accurately estimated.
Total Budget Estimate
Considering all these, a complete 3.5kVA inverter setup, including inverter, batteries, rack, cables, and installation, may cost ₦1.2 million to ₦1.6 million. If you’re adding solar panels, the total may exceed ₦2 million, depending on your energy needs and the number of panels installed.
Ideal Battery Setup for a 3.5kVA Inverter
Choosing the right battery configuration is crucial to getting the most from your 3.5kVA inverter. Since most 3.5kVA inverters operate on a 24V system, your battery bank must match that voltage requirement.
Common Recommended Setups:
2 x 12V 200Ah batteries (in series)
This is one of the most popular configurations. It provides a decent backup time and is powerful enough for most household or small business needs.
4 x 12V 150Ah batteries (2 series, 2 parallel)
This setup also gives you a 24V system but with increased capacity. It’s ideal for users who need longer backup or expect slightly higher power usage.
2 x 12V 250Ah batteries (in series)
This setup provides more amp-hours for even longer backup time while maintaining the required voltage.
Why These Setups Work
These configurations offer a balance between runtime, affordability, and physical space. A higher amp-hour rating means your appliances will run longer during a power outage. However, ensure your inverter can handle the total battery bank capacity and charge them efficiently.
Tip: Always use deep-cycle batteries, either tubular or lithium, for better durability and performance. Also, ensure all batteries used in your setup are the same age, type, and capacity to avoid uneven performance or damage.
Pure Sine Wave vs Modified Sine Wave: Which is Better for 3.5kVA?
One of the most important decisions when choosing a 3.5kVA inverter is the type of wave output. There are two main types, Pure Sine Wave and Modified Sine Wave;
- Pure Sine Wave Inverters
These produce power that closely mimics the clean electricity you get from the grid. Pure sine wave inverters are more expensive but:
- Safely power sensitive electronics (e.g., TVs, fridges, laptops)
- Extend the lifespan of appliances
- Run devices smoothly with minimal noise or interference
- Improve efficiency for inductive loads like fans and pumps
Best for: Homes and offices with multiple sensitive or motor-driven appliances.
- Modified Sine Wave Inverters
These are cheaper alternatives that produce a rougher, square-like wave. They:
- Can run simple resistive loads (bulbs, kettles)
- Often causes humming or heating in appliances
- They are less efficient and sometimes harmful to electronics
Best for: Very basic or temporary setups with minimal appliances.
Pure sine wave is the clear winner if you’re investing in a 3.5kVA inverter to support a modern home or small business. It ensures reliability, safety, and optimal performance, especially when paired with good-quality batteries and proper installation.
Conclusion
A 3.5kVA inverter is an excellent mid-sized solution if you want to escape power outages and rising generator costs. With a price point around ₦750,000, it offers great value when paired with the right batteries and installation setup.
If you want uninterrupted power for your home or small business, and you’re ready to make a long-term investment, a 3.5kVA inverter is a smart and reliable choice.
