Solar and battery systems engineered around your business load — reducing fuel and maintenance spend while keeping tills, fridges and computers running.
Most SMEs underestimate their true cost of power because it is spread across fuel receipts, maintenance invoices, prepaid units and lost sales.
Daily petrol or diesel purchases, often the single largest operating cost after rent and salaries.
Oil changes, filters, servicing and breakdown repairs — plus the cost of downtime while the generator is out.
Prepaid units or postpaid bills that continue alongside generator spend.
Closed tills, spoiled stock and idle staff whenever power fails and the generator is not running.
A small petrol generator commonly consumes around a litre of fuel per hour at moderate load; larger diesel sets consume several litres per hour. At current pump prices, every running hour is a direct operating cost — before servicing, repairs and replacement.
Worked example only. Use the calculator below with your own fuel use, hours and current prices.
Adjust fuel price, hours, maintenance and grid spend. The five-year view includes the system cost upfront and any battery replacement.
Indicative — based entirely on the values you enter.
Business loads are concentrated in daylight hours — which is exactly when solar produces. That makes SMEs among the strongest cases for solar.
Sized to carry trading-hour loads on solar, with batteries covering outages and early evenings.
Solar and batteries run day-to-day; the generator starts automatically only when storage runs low.
For premises with three-phase supply and larger motors, compressors or multiple AC units.
For shops, clinics, pharmacies, salons and offices that need dependable power through trading hours.
≈ 5.7 hours estimated battery backup at a 1,500 W average load (90% usable capacity, 90% efficiency, no solar input; heavier loads reduce backup time).
Three-phase hybrid system for offices, schools, hotels and healthcare facilities with critical loads.
≈ 5.4 hours estimated battery backup at a 3,000 W average load (90% usable capacity, 90% efficiency, no solar input; heavier loads reduce backup time).
Each sector has distinct critical loads. We design around the equipment that cannot stop.
Lighting, POS, chillers and freezers through trading hours.
Vaccine fridges, diagnostic equipment and consultation rooms.
Computers, networking, ACs and lighting without generator noise.
Classrooms, ICT labs and administration with predictable daytime loads.
Cold rooms, kitchen equipment and guest comfort.
Dryers, clippers, lighting and AC with staged high-draw loads.
Daytime solar with storage to keep tills, chillers and a family clinic running through trading hours.
A rooftop hybrid system supporting offices, networking and air conditioning for a corporate tenant.
A deposit-and-instalment plan can align repayments with the fuel savings the system delivers.
MBB FlexiPower: 40% deposit with the balance over 3, 6, 9 or 12 months. Example repayments use an illustrative 18% annual reducing-balance rate.
We schedule work around trading hours where possible, and plan changeover to keep critical loads running during installation.
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 packYes, when the system is designed for them. Inverter-type air conditioners are significantly more efficient than conventional units. Motors such as pumps and compressors draw a surge current at start-up, so the inverter must be sized for that surge. Very heavy loads such as electric cookers, water heaters and some industrial machines may be better served by the grid or generator, or by a larger engineered system.
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.
We review your fuel records, bills and equipment, survey the premises and present a design with an indicative return on investment.
