Upgrade Service

Gel Battery to Lithium Battery Upgrade

The single best upgrade you can make to your solar system.

Still running gel or flooded lead-acid batteries? You are losing money every month. Lithium batteries last 3 to 5 times longer, charge faster, weigh less, and give you more usable capacity from the same bank size. The upgrade pays for itself within years, not decades.

  • Full assessment of your existing system
  • Lithium battery sizing to match your load
  • Safe removal and responsible disposal of old gel batteries
  • Installation of LiFePO4 (lithium iron phosphate) battery bank
  • Charge controller and inverter compatibility check
  • Battery Management System (BMS) setup and testing
  • Performance benchmark before and after upgrade
  • Upgrade certificate and 2-year battery warranty

Most upgrades completed in a single day

Common Questions

Frequently Asked Questions

Questions about solar installation, maintenance, and battery upgrades in Nigeria.

How long does a residential solar installation take?

Most home installations in Port Harcourt and across Rivers State take 1 to 2 working days, depending on system size and roof type. We give you a clear timeline in your proposal.

What areas do you cover?

We install and service solar systems across Rivers State (including Port Harcourt, Obio-Akpor, Eleme, Bonny), Delta State (Warri, Asaba, Sapele), and Bayelsa State (Yenagoa, Brass). Contact us for other locations.

Is lithium really worth the upgrade from gel batteries?

Yes, for most customers in Nigeria's climate it is. Gel batteries typically last 2 to 3 years in our heat and with frequent deep cycling. LiFePO4 lithium batteries routinely last 8 to 12 years, give you nearly double the usable capacity, and require zero maintenance. The upfront cost is higher but the total cost of ownership is much lower.

Do you handle both off-grid and grid-tied systems?

Yes. We install hybrid systems that use solar as the primary source, battery storage for nights and outages, and PHCN grid as backup, as well as fully off-grid systems for locations without grid access.

What brands of equipment do you use?

We work with proven, warranty-backed brands for panels, inverters, and batteries. We discuss the best options for your budget during your free consultation.

Can you service a system installed by another company?

Yes. We service and maintain all brands and configurations. If you have an existing system that is underperforming or needs repairs, contact us for a diagnostic visit.
