5.5kVA Hybrid Solar Inverter — For Home or Scale to Commercial

The M5500 series are 48V hybrid inverters, each rated at 5.5kVA — and because both models operate at a power factor of 1.0 for standard home and office loads, their 5.5kVA rating equals 5,500 watts of real, continuous usable power per unit. The kVA figure describes the maximum total electrical load the inverter can manage at any moment; the watts figure is what your appliances actually draw from it. For these units running typical Nigerian household or commercial loads, those two numbers are identical. Think of each unit like a lane on a highway — a single M5500-48 gives you five and a half thousand watts of throughput, and the M5500-48PL lets you add up to eleven more lanes alongside it, scaling total system capacity all the way to 66,000W without changing the core inverter technology.

The two models share an identical power architecture, efficiency rating, solar input capacity, and physical form factor. The single difference is that the M5500-48PL supports parallel connection of up to 12 units in single-phase or three-phase configuration, while the M5500-48 operates as a standalone unit. Both include a built-in mobile screen for direct system monitoring without a phone or additional device.

What “Hybrid” means:

A hybrid inverter manages three power sources simultaneously — solar panels, a battery, and the national grid — and automatically selects which one to draw from at every moment based on your chosen priority setting. During daylight hours, solar powers your appliances and charges the battery at the same time. After sunset, the battery carries the load. If the battery runs low and NEPA supply is present, the inverter draws from the grid to sustain your appliances and recharge the battery for the next cycle. Both M5500 models can also operate without a battery installed, running loads directly from solar panel output during daylight — which means you can commission the system with panels only and add battery storage later.

What This Inverter Can Power

At 5,500W of continuous output per unit and 11,000VA of surge capacity:

• 1HP split-unit air conditioner × 2 (approximately 900–1,100W each running; up to 3,000W each at startup)
• Full-size refrigerator, 300–400 litre (200–350W running)
• Chest freezer, 200 litre (150–200W running)
• LED bulbs × 15 (10–20W each, 150–300W total)
• Ceiling fans × 4 (60–80W each, 240–320W total)
• LED television, 55–65 inch (150–200W)
• Desktop computers or laptops × 3 (60–150W each)
• WiFi router, decoder, and network switch (50–70W combined)
• Water dispenser, hot and cold (300–500W)
• Printer and office equipment (100–200W)
• Phone chargers and small electronics (60–100W)

For the M5500-48PL in a parallel configuration, multiply the available capacity by the number of units connected — two units deliver 11kVA, four units deliver 22kVA, and twelve units deliver 66kVA, making it suitable for event centres, office complexes, filling stations, clinics, and multi-unit residential developments across Lagos, Abuja, and Nigeria at large.

Limitations — What to Know Before You Buy

The M5500-48 is a standalone unit with no expansion capability — if your load grows beyond 5.5kVA, you would need to replace it rather than add to it. If there is any possibility your power needs will scale in the near future, the M5500-48PL is the smarter starting point, as it allows you to begin with one unit and add more as your load or budget grows. Neither model supports electric cookers, water heaters, pressing irons, or borehole pumps above 1HP — their heating elements and large motors draw continuous power that crowds out every other appliance on the circuit. Both units require a 48V battery system, meaning four 12V batteries in series, two 24V batteries in series, or a purpose-built 48V lithium pack — existing 12V or 24V battery banks from a previous inverter cannot be reused without significant expansion. Our team in Lagos will help you determine whether the standalone or parallel model is the right fit before you commit.

Which Model Is Right for You?

If you are powering a single home, apartment block, or small business and have no plans to expand the system beyond 5.5kVA, the M5500-48 gives you everything you need at a lower cost. If you are powering a commercial property, a large facility, a multi-unit development, or any installation that may need more capacity in the future, the M5500-48PL is the practical choice — start with one unit, add more as your load grows, and never replace the inverter at the centre of the system.

Battery Compatibility

Both M5500 models operate on a 48V battery system, requiring four 12V batteries wired in series, two 24V batteries in series, or a single 48V lithium battery pack. Both are compatible with LiFePO4 lithium batteries. Lithium batteries are the stronger long-term investment at this capacity level — they last 8–10 years under regular deep cycling, charge faster, and tolerate deeper discharge without capacity loss. For buyers starting with conventional lead-acid tubular batteries, the 48V configuration still delivers strong performance and the system can be upgraded to lithium at a later stage. For M5500-48PL installations in a parallel configuration, battery bank sizing becomes a critical calculation — each additional unit increases both the load coverage and the charging demand on the battery bank. Our team can size the right battery capacity for your specific configuration and daily load.
