Four AC outlets, a direct-connect terminal block, and front-panel volt and amp meters — purpose-built for 48V power sources where minimizing DC current and cable losses matters most.
The AIMS Power 5000 Watt 48V Modified Sine Wave Inverter (PWRINV500048W) converts 48V DC battery power into 120V AC at a continuous 5000 watts — with 10,000-watt peak surge capacity for motor and compressor startups. Operating at 48V dramatically reduces DC current draw compared to 12V or 24V systems at the same output, cutting cable losses and heat while improving overall efficiency at heavy loads. Four AC receptacles plus an AC direct-connect terminal block give you the flexibility to run multiple loads or hardwire heavy equipment directly to the inverter's full output, while front-panel volt and amp meters keep you informed of battery condition and current draw at all times.
The PWRINV500048W brings the AIMS Power 5000W platform to 48V systems — the most efficient DC voltage class for this output level, with the monitoring and output flexibility demanded by serious off-grid and solar installations.
At 48V, this inverter draws roughly a quarter of the DC current of an equivalent 12V model at the same output — minimizing cable losses, heat, and conductor size requirements, and maximizing efficiency through the entire wiring system.
5000 watts of continuous AC output with 10,000-watt peak surge capacity — enough to start refrigeration compressors, pumps, and heavy tools that demand extra current at startup.
Four 3-prong AC receptacles plus an AC direct-connect terminal block for permanent hardwiring. All outlets share the inverter's full 5000W capacity. Add a splitter for additional plug positions. Each outlet is UL-rated for 1500W individually.
At up to 41.6 AC amps, this inverter handles loads that smaller inverters can't sustain — refrigerators, freezers, large power tools, compressors, and multi-load setups all within reach.
Front-panel volt and amp meters give you real-time visibility into battery voltage and current draw — so you know exactly how hard your battery bank is working and can plan around remaining capacity.
90% efficient at full load and 95% at one-third load, with a no-load draw under 0.2A — among the lowest idle draws in the AIMS Power lineup, conserving battery capacity during standby.
The PWRINV500048W comes pre-wired for an optional remote on/off switch, letting you power the inverter on and off from a remote panel without accessing the unit directly. A pre-slotted mounting plate integrated into the aluminum case allows permanent bolted installation on walls, floors, or equipment frames. The single thermally controlled cooling fan only engages when the inverter's temperature requires it, keeping standby operation quiet. Most fault conditions trigger an automatic reset once the fault clears — no manual intervention required in most cases.

At 5000W output, a 48V inverter draws roughly a quarter of the DC current of an equivalent 12V model — around 104A at 48V versus over 400A at 12V. Lower DC current means dramatically reduced cable losses, less heat, and the ability to use thinner conductors over longer runs. For larger off-grid solar systems, 48V is the standard battery voltage for exactly this reason. If your battery bank is already configured at 48V, this is the direct match without any voltage conversion equipment.
No. The PWRINV500048W requires a 48V DC input — its operating voltage range is 39–64V DC. It will not operate on 12V or 24V battery systems. For 12V applications at 5000W, see the AIMS Power PWRINV500012W; for 24V, see the PWRINV500024W.
At 5000W continuous and 41.6 AC amps, this inverter can run most large household and commercial loads — refrigerators and freezers, microwave ovens, air conditioning units (check startup surge requirements), water pumps, power tools, compressors, and more simultaneously. Modified sine wave works well for most resistive and motor-driven loads. Variable-speed drives, certain medical equipment, laser printers, and sensitive audio gear may perform better on pure sine wave. Each individual outlet is UL-rated for 1500W; the AC terminal block can carry the full 5000W for hardwired loads.
At 5000W from a 48V bank, DC current draw is approximately 104A at full load — the lowest current draw of any AIMS Power 5000W inverter. A deep-cycle AGM or lithium battery bank at 48V, typically 100Ah or more, provides meaningful sustained runtime. Because 48V systems use less current for the same power, cable sizing is more forgiving than 12V or 24V equivalents. For solar-supplemented systems, size your panel array and charge controller to replenish the draw during the day.
With a no-load draw under 0.2A, this inverter consumes very little battery capacity while switched on but idle — among the lowest standby draws in the AIMS Power lineup. This means you can leave the inverter powered on continuously without it meaningfully depleting your battery bank between periods of active use, which is especially valuable in solar systems where every watt-hour of stored energy matters.
This inverter is backed by a 2-year manufacturer warranty from date of purchase, plus free lifetime technical support from AIMS Power's tech team. As an authorized AIMS Power dealer, TrueStead Supply ensures your warranty is valid from day one.
