Power outages in Nigeria are nothing new. Homes, shops, offices, and schools deal with unstable electricity daily. That’s why solar storage systems are becoming a serious alternative to generators. One product that has gained massive attention recently is the itel IESS-3K680N all-in-one power tank from itel Energy.
This review covers everything about the unit, specifications, pricing, performance, where to buy, business opportunities.
Overview of the itel IESS-3K680N Power Tank
The itel IESS-3K680N is an all-in-one solar power station built for homes and small businesses. Instead of buying separate inverters, batteries, controllers, and installation kits, everything comes inside one integrated unit.

Why Many Nigerians Prefer It Over Competitors
Premium portable power stations like those from EcoFlow and Bluetti are well known globally, but they are often two to three times more expensive in Nigeria.
The itel system stands out for several reasons.
1. All-in-One Setup
Traditional solar installations usually require:
- inverter
- batteries
- charge controller
- wiring
- installation labor
- The itel system combines everything into one box, reducing installation cost significantly.
- Users often report saving up to 50% in setup cost.
2. Lower Entry Price
Compared to international brands, the itel system enters the market at a much lower price while still offering strong capacity.
3. Faster UPS Switching
The <16ms switchover time is faster than many budget inverter systems.
4. Local Support
Repairs and warranty support are handled through Carlcare service centers, which already support itel devices across Nigeria.
Current Price in Nigeria (2026)
Prices vary depending on retailer and promotions, especially on different platforms.
itel IESS-3K680N (3600W + 8kWh) Typical price range:
₦1,680,000 – ₦1,927,475
Solar Panel Bundles
Installers sometimes bundle the system with 4 to 8 solar panels (550W each).
Total bundle price may reach ₦3.2 million or more, depending on installation and wiring.
Smaller Option: itel 500W / 1kWh Power Tank
itel also sells a smaller entry-level model.
Typical Nigerian price: ₦320,000 – ₦450,000
Users commonly buy it for powering:
- TV
- fan
- laptop
- phones
- Wi-Fi router
- Many reports say it lasts about 7 hours overnight for basic home usage.
- A full setup with 400-530W solar panel and wiring costs roughly ₦465,000.
- For small apartments or single rooms, this option is often enough.
Installment Payment
The system can also be purchased gradually through the CDcare installment platform, allowing users to pay over time.
Business Opportunities Around the Power Tank
Demand for solar backup systems in Nigeria is growing quickly.
Because of that, the itel power tank has also created small business opportunities.
Reselling
Many dealers buy the units wholesale and resell them with ₦30,000 – ₦50,000 markup.
Installation Services
Solar technicians earn additional income installing panels and wiring systems.
Typical installation charges range from: ₦10,000 – ₦20,000, depending on complexity.
Charging Stations
Some users run phone charging stations using the smaller 500W unit.
In areas with poor electricity, this can generate daily income.
Return on Investment
Many buyers compare the system against generator fuel costs.
With petrol prices rising, generator users often spend large amounts monthly on fuel and maintenance.
Users report the system can pay for itself within 1–2 years depending on usage.
Savings come from:
