Overview

The MUST PV18-5248 PRO is a 5.2kW (5,200W), 48V hybrid solar inverter from MUST's PV1800 PRO series. It combines a pure sine wave inverter, a 100A MPPT solar charge controller and a battery charger in one wall-mounted unit, and switches automatically between solar, grid and battery power. Who it's for Homes, shops and small offices with a 48V battery bank who want to run on solar during the day, recharge from solar or the grid, and keep the power on during outages. What it can power It delivers 5,200W continuously, which is about 4–5kW of everyday loads (lights, fans, TVs, fridge/freezer, computers, a 1HP air conditioner or pump), with a 10.4kW surge for motor starts. How long it runs depends on your battery bank, not the inverter. These figures are estimates; actual performance depends on your appliances, batteries and installation. Key specifications in plain language • Solar: 100A MPPT charge controller taking up to 6,000W of panels (for example 10 x 550W in two strings), with string open-circuit voltage kept below 450V. • Charging: up to 100A total battery charging (solar + grid), with lead-acid and lithium charging profiles. • Grid: wide input range (170–280V in UPS mode, 90–280V in appliance mode) to cope with unstable supply, with a 10ms transfer time. • Runs loads from solar even without a battery. • Cold-start capable. • Anti-dust kit included. • Size: 309 x 505 x 147mm and 12.9kg, for indoor wall mounting. Compatibility Use it with a 48V battery bank: lithium (LiFePO4), flooded/tubular, AGM or gel. Set the battery type in the inverter menu before first use. Install it indoors in a ventilated space, with correctly sized battery and PV cables, breakers and earthing. Installation should be done by a qualified installer. Warranty & support 2 years from MUST, the manufacturer. We supply this product through a partner supplier, so claims are handled by MUST through that supplier; keep your proof of purchase and installation records.

Questions about this product

What can it power?

It delivers 5,200W continuously, which is about 4–5kW of everyday loads (lights, fans, TVs, fridge/freezer, computers, a 1HP air conditioner or pump), with a 10.4kW surge for motor starts. Add up the wattage of everything you want to run at the same time and keep it under the rating.

Which batteries does it work with?

Any 48V battery bank: lithium (LiFePO4), flooded/tubular, AGM or gel. From our range, that includes the Felicity LPBF48100 (5kWh) and Felicity FLA48100 (5.12kWh). Set the inverter's battery type to match. Four 12V batteries in series also make 48V. Lithium BMS communication: Yes, lithium BMS communication via CAN port. Ask your installer to confirm the battery's protocol is supported. To run the full 5,200W from batteries, the bank must supply about 120A continuously, so check the batteries' discharge rating and add batteries in parallel if needed.

How many solar panels can I connect?

The built-in MPPT controller takes up to 6,000W of panels (for example 10 x 550W in two strings), with string open-circuit voltage kept below 450V. A qualified installer should design the strings.
