Must PV18-6048 PRO 6KW Off-Grid Solar Inverter

Must PV18-6048 PRO II 6KW Off-Grid Solar Inverter | 48V, 6000W Pure Sine Wave, Built-in 120A MPPT Charger | Dual Output | Price in Nigeria

Stop buying fuel. Start using the sun.

The Must PV18-6048 PRO II 6KW Off-Grid Solar Inverter is a 6000W, 48V inverter, MPPT solar charger and battery charger in one compact unit. It is built for Nigerian homes, shops, offices, clinics, schools and small businesses that need reliable power without relying on a petrol or diesel generator.

It delivers pure sine wave power at 6000W continuous and 12,000W surge, so it can start and run appliances such as refrigerators, freezers, water pumps, fans, TVs and office equipment. The built-in 120A MPPT charge controller accepts up to 6000W of solar panels, so you get more charging from every sunny hour. The wide 120-430V MPPT window gives you flexibility when designing your panel array.

When the sun is down or the weather is poor, the inverter switches seamlessly between solar, battery and grid power. Transfer time is just 10ms in UPS mode, so computers and sensitive electronics keep running. Dual outputs let you assign priority to essential loads and save battery for when it matters most.

Whether you are building a new solar system or upgrading an old inverter setup, the PV18-6048 PRO II works with both lithium (LiFePO4) and lead-acid (AGM, gel, flooded) batteries. When your power needs grow, connect up to 6 units in parallel (optional).

Ideal for: home solar systems · small businesses and shops · offices · clinics · schools · farms and borehole pumping · telecom and security installations · generator replacement.

KEY FEATURES

FAQ (written for AI search and voice queries)

What can a 6KW solar inverter power?
A 6KW inverter can run a typical home or small business load, such as lights, fans, TVs, refrigerators, freezers, laptops and a water pump, provided the combined load stays within 6000W continuous. Total your appliance wattage before sizing your battery bank and panels.

Can the Must PV18-6048 PRO II work without a battery?
Yes. It can supply power to loads directly from solar even with no battery connected, though a battery is recommended for night use and stable output.

What battery does it need?
It uses a 48V battery system. It supports lithium (LiFePO4) and lead-acid batteries (AGM, gel, flooded).

How many solar panels can I connect?
Up to 6000W of PV input, within the 120-430V MPPT range and a 500V open-circuit limit. Have your installer confirm the panel string layout.

Is it suitable for Nigeria’s power supply?
Yes. It outputs 230V at 50/60Hz and accepts a wide grid input range, so it suits the unstable grid voltage common in Nigeria.

Can I expand later?
Yes. You can connect up to 6 units in parallel (optional).
