4000W 48VDC Pure Sine Inverter Charger MS Series
MS4048 (MS4048-L, MS4048-20BL)

The MS Series Inverter/Charger - a pure sine wave inverter designed specifically for the most demanding mobile, backup, and off-grid applications. The MS Series Inverter/Charger is powerful, easy-to-use, and best of all, cost effective.

Battery Profile Presets: Using the ME-RC, ME-ARC, or ME-MR Remote Controls, easily choose from and set standard battery profiles, including Lithium Iron Phosphate (LFP) - only available via the ME-RC and ME-MR, Gel, Flooded, AGM1, and AGM2.

Power Factor Corrected (PFC) Charger: Our PFC charger is built into all of our inverter/chargers. It uses less energy from a generator than a standard charger - using 25-30% less AC current than standard chargers.

Expanded Transfer Relay: 60 Amp transfer service is available on all models except MS2000, which is 30 Amp only.
