Battery Backup for Iraqi Shops vs Homes: Different Needs

A retail shop in Baghdad and a family home in Basra both need backup power — but they need very different systems. Matching the wrong product to the use case means either overspending or underserving the customer. Here is a practical breakdown.

The Home Use Case: Lights, Fans, Fridge, Router

A typical Iraqi household needs backup for 6-8 hours per day. The priority loads are:

• LED lights (5-10 fixtures, 50-100W total)
• Ceiling fans or small AC (200-1000W)
• Refrigerator (150-300W running, 1000W surge)
• Wi-Fi router and phone charging (20-50W)
• TV (50-150W)

Total continuous load: 500-1500W. Energy needed for 6 hours: 3-9 kWh.

The ideal solution is a SH-Home residential battery system with 5-10 kWh of LiFePO₄ storage and a 3 kW hybrid inverter. This covers the essentials quietly and cleanly, with solar panels to recharge during the day.

For smaller apartments or renters who cannot install a permanent system, a portable power station in the 1-2 kWh range handles lights, router, phone charging and a small fan for 4-6 hours.

The home priority is silence, reliability and overnight operation. Nobody wants a generator running outside their bedroom window at 2 AM.

The Shop Use Case: Registers, Displays, Cold Chain

A retail shop, pharmacy or small restaurant has different priorities:

• Point-of-sale system — must stay up to process payments
• Refrigeration — perishable inventory depends on continuous cooling
• Lighting — customers will not shop in the dark
• Security system — cameras and alarms must stay active
• Air conditioning — customer comfort drives sales

Total continuous load: 1500-4000W. Energy needed for 6-8 hours: 10-30 kWh.

For shops, the key differences from homes are:

Higher surge capacity

Commercial refrigerators and AC units have massive startup surges. The inverter needs 2-3x surge rating minimum. A stackable battery system paired with a 6-12 kW hybrid inverter handles this easily.

Longer runtime requirement

Shops typically operate 10-14 hours per day. If the grid is unreliable throughout, the battery system needs enough capacity to cycle multiple times — or solar panels large enough to recharge during operating hours.

Three-phase power

Many commercial properties have three-phase electrical service. A single-phase inverter cannot properly back up a three-phase installation. You need either a three-phase inverter or a properly engineered split of loads.

Side-by-Side Comparison

The Hybrid Approach: Home + Shop

Many Iraqi businesses are family-run from the same building as the home. In these cases, a single larger system can serve both — but the design must account for:

• Load prioritisation: The system should automatically cut non-essential loads (e.g., AC) when battery is low, keeping critical loads (fridge, lights, POS) running
• Sufficient capacity: Plan for the combined peak load, not just the larger of the two
• Separate circuits: Shop and home should be on separate breakers for safety and control

What About Clinics and Medical Facilities?

Medical clinics are a special category. They need:

• UPS-grade transfer time (<10ms) for sensitive medical equipment
• Redundant capacity — the battery should never run to zero
• Clean sine wave output — modified sine wave can damage medical electronics
• Silent operation — patients cannot rest next to a generator

For clinics, a 10-16 kWh system with a pure sine wave hybrid inverter is the minimum viable configuration.

Bottom Line

Homes need silence, reliability and 5-10 kWh of storage. Shops need surge capacity, longer runtime and 10-20+ kWh. Getting the sizing right is the difference between a satisfied customer and a returned product — so always calculate the actual load before recommending a system.
