Estimate your inverter, solar panel and lithium battery requirements from your appliance list — with an indicative installed cost range at MBB Energy rates.
Start from a typical home, business or commercial list and edit quantities, wattage and daily hours.
Items that may run at the same time determine your peak load and inverter size.
Pick how many hours of battery supply you need when there is no sun or grid.
See inverter kVA, solar kWp and battery kWh instantly, then unlock the cost range and PDF.
Indicative only — final design follows an engineer’s site assessment.
This is a preliminary sizing based on your inputs and standard engineering assumptions. It is not a final engineering design. Cost ranges use MBB indicative rates (₦350,000/kVA inverter, ₦250,000/kWp panels, ₦400,000/kWh lithium storage, plus 15% installation and balance of system). Your final quotation follows a site assessment.
An engineer confirms your loads on site, checks wiring, earthing and roof space, and selects specific equipment — then issues a formal quotation.
Dependable backup for lighting, fans, entertainment and refrigeration in apartments and smaller homes.
≈ 6.5 hours estimated battery backup at a 300 W average load (90% usable capacity, 90% efficiency, no solar input; heavier loads reduce backup time).
For family homes that want comfortable evenings, longer backup and room for a freezer and pump.
≈ 7.1 hours estimated battery backup at a 400 W average load (90% usable capacity, 90% efficiency, no solar input; heavier loads reduce backup time).
High-capacity system for larger residences aiming to substantially reduce generator dependence.
≈ 8.2 hours estimated battery backup at a 700 W average load (90% usable capacity, 90% efficiency, no solar input; heavier loads reduce backup time).
Book a site assessment and an MBB Energy engineer will confirm your system on site.
