Your Complete Guide to Inverter + Solar Panel Integration in Nigeria: Sizing, Setup & Savings
As Nigeria continues to battle unstable electricity supply and rising energy costs, more homes and businesses are turning to solar power with inverter systems as a sustainable and cost-effective solution. At Dansmart Elektrotech Ltd, we specialize in providing smart energy solutions, and our preferred inverter brand is the globally trusted Victron Energy — known for its efficiency, durability, and intelligent energy management.
In this guide, we break down everything you need to know about integrating inverters and solar panels — from system sizing to setup, to the real savings you can expect.
1. What Is Solar + Inverter Integration?
A solar + inverter system combines solar panels, inverter(s), batteries, and a charge controller to generate and manage your electricity. Solar panels capture sunlight and convert it into DC electricity. The Victron inverter then converts this DC into usable AC electricity to power your home or office.
2. Why Choose Victron Inverters?
At Dansmart, we use Victron inverters for a reason. They offer:
- High efficiency (up to 98%)
- Modular system expandability
- Remote monitoring via Victron VRM
- Unmatched durability even in harsh Nigerian climates
- Compatibility with lithium and deep-cycle batteries
Whether you’re powering a home, shop, or office, Victron inverters deliver reliable and seamless energy.

3. How to Size Your Solar + Inverter System
Getting the right size is crucial. Here’s a basic guide to help you understand the sizing process:
A. Calculate Your Load (What You Want to Power)
List out all the appliances you want to power and their wattage. For example:
| Appliance | Quantity | Wattage | Total Watts |
|---|---|---|---|
| LED Bulbs | 10 | 10W | 100W |
| Fan | 2 | 70W | 140W |
| TV | 1 | 120W | 120W |
| Fridge | 1 | 150W | 150W |
| Laptop | 2 | 60W | 120W |
| Total Load: 630W |
B. Inverter Size
Choose an inverter with at least 20% more capacity than your total load. For 630W, go for a Victron 800W–1kVA inverter or higher.
C. Battery Bank
Assume you want to run your system for 6 hours:
- 630W x 6h = 3,780Wh
- For a 12V system: 3,780Wh ÷ 12V = 315Ah
- You’ll need at least 2 x 12V 200Ah batteries (deep-cycle).
D. Solar Panel Size
To charge the batteries daily:
- Assume 5 hours of sun per day in Nigeria
- 3780Wh ÷ 5h = 756W solar panels
- Round up to 800W – 1kW of solar panels
