Three devices in one compact unit: 1500W inverter, 10A battery charger, and built-in transfer switch — no manual switching, no missed outages.
The AIMS Power PWRIC1500W is a 1500-watt modified sine wave inverter charger with a built-in automatic transfer switch, engineered specifically for home backup power. Plug it into a standard AC outlet and connect your battery bank — when utility power fails, the unit detects the outage and automatically switches your connected equipment to battery power within 3–10 seconds, no intervention required. The integrated 10-amp charger keeps your batteries topped off whenever shore power is available, so you're always ready when a storm or outage hits. Built on an all-aluminum chassis with internal fuse protection and thermal management, the PWRIC1500W is a proven, compact solution for basement sump pump backup, home emergency circuits, RV power, and marine applications.
The PWRIC1500W combines inverter, charger, and transfer switch into one wall-mountable unit — eliminating the need for three separate components while providing automatic, hands-free backup protection.
When utility power is lost, the built-in transfer switch detects the outage and seamlessly switches your equipment to battery power — automatically, every time, with no manual action required.
1500 watts of continuous output handles sump pumps, lights, fans, and small appliances — while a 3000-watt surge capacity handles the inrush current when motors start up.
The onboard 10-amp DC charger keeps your battery bank at full capacity whenever grid power is available, so your backup is always ready for the next outage.
Operating efficiency of 85–90% with a no-load draw of just 0.6 amps means your battery bank lasts longer in standby and delivers more usable runtime when you need it.
At just 7 lbs and 15.5" × 7.75" × 3.25", the aluminum housing provides optimal heat dissipation for long-term reliability — with a pre-slotted mounting plate for permanent wall installation.
Over-temperature protection, overload protection, AC output short-circuit protection, internal fuse protection, and automatic low-voltage shutdown at 10V DC all work together to safeguard your equipment and the unit itself.
Two dedicated indicator LEDs keep you informed without guesswork. The green LED confirms that AC input power is live and your battery is actively charging. The red LED signals that grid power has been lost and the unit is running from your battery bank. No app, no display panel required — a quick visual check tells you everything you need to know about your backup system's status.

The PWRIC1500W switches from grid to battery power in 3–10 seconds after utility power is lost. This is sufficient for most sump pumps and household backup applications, though it is not an uninterruptible power supply (UPS) — there is a brief interruption during transfer.
The PWRIC1500W requires a 12V DC battery bank — a deep-cycle AGM or flooded lead-acid battery is the most common choice. Battery capacity (measured in amp-hours) determines your runtime: a larger bank gives you longer backup time. The unit does not include a battery; it must be purchased separately and connected via DC cables.
Yes — backing up sump pumps is the primary designed use case for this unit. Most standard residential sump pumps draw between 300W and 800W continuously, well within the 1,500W continuous rating. The 3,000W surge capacity also handles the motor startup inrush current that sump pumps require. Verify your pump's wattage before purchase to confirm compatibility.
Plug the included AC cable from the PWRIC1500W into a standard wall outlet (shore/grid power). The unit monitors incoming AC voltage. When grid power drops or is lost, the transfer switch automatically disconnects from shore power and begins inverting from your battery bank — no manual action required. When grid power returns, the unit transfers back to shore power and resumes charging the batteries.
The green LED means AC input (grid) power is present and functional, and the built-in charger is actively charging your battery bank. The red LED means AC input power is not available — the unit is operating from your battery bank and inverting DC to AC to power your connected devices.
Runtime depends on your battery bank's amp-hour (Ah) capacity and the load you're running. As a rough guide: a 100Ah 12V battery at 85–90% inverter efficiency delivers approximately 1 kWh of usable energy. A 500W sump pump load would provide roughly 2 hours of runtime from a 100Ah battery. Larger or multiple batteries extend runtime proportionally. The unit draws only 0.6A at no load, so idle standby draw is minimal.
A modified sine wave is a stepped approximation of the pure sine wave produced by the utility grid. It works well for most resistive loads (lights, heating elements), motor-driven tools, and many appliances. However, some sensitive electronics — including certain medical equipment, variable-speed motors, laser printers, and audio equipment — may not perform optimally or may not be compatible. If you're powering sensitive electronics, consider a pure sine wave inverter. For sump pumps, fans, lighting, and basic appliances, modified sine wave is generally suitable.
The PWRIC1500W's built-in charger is designed for standard 12V lead-acid and AGM batteries. The charger output and charge profile may not be optimized for lithium iron phosphate (LiFePO4) batteries, which typically require a different charge voltage profile. If you intend to use a lithium battery, verify the battery manufacturer's charge requirements and consider a separate lithium-compatible charger. The inverter/transfer switch functions will still operate within the 10–15V DC input range.
The PWRIC1500W can draw up to 125A DC at full load. For safety and performance, use appropriately sized, short DC cables — typically 2 AWG or 1/0 AWG copper cables with an inline fuse or circuit breaker rated for the current draw and cable gauge. Cable length should be kept as short as possible to minimize voltage drop. DC cables are sold separately; AIMS Power offers compatible cable kits.
Yes. The PWRIC1500W features a pre-slotted mounting plate built into the unit, designed for permanent wall or panel installation. Mounting hardware is not included — standard screws appropriate for your wall type are required. Mount in a dry, ventilated location near your battery bank to minimize DC cable length.
The PWRIC1500W includes over-temperature protection (shuts down if the unit overheats), overload protection, AC output short-circuit protection, internal fuse protection, automatic low-voltage shutdown (at 10.0V ± 0.5V DC to protect your battery), a low-voltage alarm (at 10.5V ± 0.5V), and high-voltage protection (cuts off at 15V DC input). The aluminum case and single cooling fan also provide passive and active thermal management.
Yes. The PWRIC1500W is well-suited for RV and marine applications where a 12V battery bank and shore power hookup are available. The automatic transfer switch handles the transition between shore power and battery power seamlessly, and the compact, mountable aluminum housing is practical for confined spaces. Confirm your RV's shore power outlet and battery system compatibility before installation.
