Must PV39-12048 PRO 12KW Off-Grid Solar Inverter

Must PV39-12048 PRO 12KW (12KVA) Off-Grid Solar Inverter | 48V Low Frequency Pure Sine Wave with Built-in 200A MPPT Charge Controller | Nigeria

Stop paying for fuel. Stop depending on the grid.

The Must PV39-12048 PRO is a 12KW off-grid solar inverter for homes, shops, offices, farms, clinics, schools and small factories across Nigeria that need reliable, heavy-duty backup power. It combines an inverter, an MPPT solar charge controller and a battery charger in one wall-mounted unit.

Its low frequency design is built for demanding loads. It delivers a 36,000VA surge, so motors, pumps, freezers and air conditioners start without tripping. Pure sine wave output keeps your electronics safe, and the 10ms transfer time keeps your power steady when you switch between solar, grid and generator.

The built-in 200A MPPT controller handles up to 10,000W of solar panels, so you don’t need a separate charge controller. The charger supports lead-acid, gel and lithium batteries on a 48V system, and you can set the charge current and charging priority from the LCD. Need more power later? Connect up to 3 units in parallel.

Choose the PV39-12048 PRO if you want to:

• Replace or cut down your petrol or diesel generator use

• Run a large home, estate, office, shop or light commercial load on solar

• Power borehole pumps, freezers, ACs and workshop equipment

• Build a scalable solar system that can grow with you.
