Hybrid solar, inverter and lithium battery systems sized to your household — so evenings, sleep and work-from-home no longer depend on the grid or the generator.
*After design approval and equipment delivery.
The problems are consistent across Lagos, Abuja, Port Harcourt and beyond — and each one has an engineering answer.
Supply often fails when the household is home — evenings, nights and weekends.
Fuel, servicing and repairs add up to a significant monthly household expense.
Generators disturb sleep, neighbours and outdoor living, and fuel storage carries risk.
Voltage swings and abrupt changeovers shorten the life of fridges, ACs and electronics.
System size is driven by the appliances you want to run — and how many run at the same time. These tiers are a guide; your load survey sets the final design.
High-draw appliances such as electric cookers, water heaters, conventional (non-inverter) ACs and electric irons significantly increase the required inverter and battery size. We may recommend running them on grid or generator supply.
Edit the typical home list below to match your appliances. You will see a preliminary configuration instantly.
Indicative only — final design follows an engineer’s site assessment.
The right configuration depends on how reliable your grid supply is and how much you want to reduce generator use.
Inverter and batteries charged from the grid. Useful where outages are short and roof space is limited, but does not reduce energy costs.
Best for: Short outages, minimal budgetSolar panels, hybrid inverter and lithium batteries working alongside grid and generator. The most common choice for Nigerian homes.
Best for: Most homesSolar and storage sized to carry the home without grid supply, with a generator as a seasonal backup only.
Best for: No reliable grid, remote sites
Rated in kVA, the inverter converts battery and solar power into household AC electricity. It must handle your simultaneous load plus start-up surges from compressors and pumps. A hybrid inverter also manages solar charging, grid charging and generator changeover, prioritising the cheapest available source.
Rated in kWh, the battery stores energy for night-time and outages. Lithium iron phosphate (LiFePO4) batteries allow deeper usable capacity, many more cycles and no routine maintenance compared with lead-acid. Backup time is usable kWh divided by your average load — for example, ≈ 8 kWh usable runs an 800 W load for about 10 hours.
Rated in kWp, the panels must produce enough energy each day to run daytime loads and recharge the battery. Undersizing the array is a common reason batteries never fully charge.
Each package is confirmed against your load survey before quotation.
Full package details 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).

Indicative — based on the figures you enter.
From the existing generator setup to the finished array, power room, protection board and handover — every stage is documented.
We discuss your objectives, current power sources, outage pattern and budget, and review any preliminary calculator results.
Output: Agreed scopeAn engineer inspects the property, distribution board, earthing, roof or mounting area and records the loads to be supported.
Output: Load scheduleWe size the inverter, PV array and storage, select protection devices and prepare a single-line diagram and layout.
Output: Design & quotationMounting, PV, inverter, battery, cabling, isolation, surge protection and earthing are installed to the approved design.
Output: Installed systemWe verify polarity, insulation, protection and settings, test changeover and charge behaviour, and configure monitoring where included.
Output: Commissioning recordYou receive an operating walkthrough, system documentation and warranty information, followed by agreed after-sales support.
Output: Handover packYour handover pack records every component, setting and warranty. Essential Care keeps your system inspected, cleaned and performing.
Recommended care: clean panels periodically (more often during Harmattan), keep the inverter area ventilated and dust-free, and avoid adding heavy loads without a design review.
Compare maintenance plansSystem size depends on two things: how much energy you use in a day (kWh) and how much power you draw at the same time (kW). Our online calculator gives a preliminary estimate from your appliance list. A final design is only produced after an engineer completes a load survey at your property, because actual usage patterns, appliance condition and cabling all affect the result.
Backup time equals usable battery energy divided by the load you run. For example, a 10 kWh lithium battery with about 8 kWh usable could run an 800 W average load for roughly 10 hours. Running more appliances shortens backup time. We always state the load assumption behind any backup figure — no system can guarantee uninterrupted power under every condition.
Most residential systems are installed in one to three days after design approval and equipment delivery. SME systems commonly take several days, while commercial and industrial projects follow a project schedule agreed during design.
Cost depends mainly on inverter capacity, solar array size, battery storage and installation complexity, and is affected by exchange rates and equipment availability. Our calculators show an indicative range based on our current unit rates and published assumptions. A formal quotation is provided after a site assessment.
Solar systems need relatively little maintenance. Panels benefit from periodic cleaning, especially in dusty Harmattan months. Connections, protection devices and battery health should be inspected periodically by a qualified technician. Lithium batteries do not need water top-ups.
Equipment warranties are provided by manufacturers and vary by product — panels often carry separate product and performance warranties, while inverters and batteries have their own terms. Installers usually provide a separate workmanship warranty. MBB Energy systems carry: solar panels 12 years product and 25 years performance; inverters 5 years; lithium batteries 5 years; and a 2-year MBB workmanship warranty. We register manufacturer warranties at handover and manage claims for you.
An engineer visits to survey your appliances, distribution board, earthing and roof, then prepares a system design and formal quotation.
