APC Back-UPS ES UPS Systems

APC Back-UPS ES standby UPS systems

The APC Back-UPS ES series is APC by Schneider Electric's entry-level battery backup line, built around standby (offline) topology. It is designed for desktop PCs, home offices, Wi-Fi routers and modems, small networking equipment, and point-of-sale terminals, the kind of single-workstation loads that need clean shutdown protection and surge defense rather than continuous power conditioning. Within the broader APC lineup, the Back-UPS ES sits below the line-interactive Back-UPS Pro and the Smart-UPS family, trading advanced regulation for a simple, compact footprint. Models in this series run from about 550 VA / 330 W up to 900 VA / 540 W, all in a tower / desktop form factor with a simulated (stepped) sine wave output.

Models in this series

A 230 V variant (BE700G-GR) is also available for non-North-American outlets. See the full range below for current models, pricing, and availability.

How to choose

VA vs. watts. A UPS is rated in both volt-amps (VA) and watts (W); your equipment must stay under both figures. Watts is the real limit for modern PCs and network gear, so size to the wattage first. Add up the wattage of everything you want on battery, then pick a model with headroom above that total, for example, a desktop plus a monitor and a router typically lands well within the 330 to 540 W range these units provide.

Runtime expectations. Standby UPS systems in this class are built for ride-through and graceful shutdown, not for running equipment for hours. At roughly half load expect on the order of 11 to 14 minutes, and only a few minutes at full load. That is enough to save work and shut down cleanly through a typical brief outage or to bridge to a generator. The Back-UPS ES models are not designed for external extended-runtime battery packs; if you need long runtime, step up to a line-interactive or online APC series.

Topology. The entire Back-UPS ES series is standby: it runs equipment from utility power and switches to battery on an outage. This is the right, cost-effective choice for home and small-office loads. If you have sensitive equipment that demands automatic voltage regulation under brownouts, or you are protecting servers and continuous-operation systems, look at line-interactive (Back-UPS Pro / Smart-UPS) or double-conversion online APC families instead.

Form factor. Every model here is a compact tower / desktop unit; the BE700G3 can also be wall- or floor-mounted. There are no rackmount units in this series.

Why this series

• Battery backup plus full surge protection on dedicated outlets, with extra surge-only outlets for peripherals.
• Compact tower design that fits under a desk or on a shelf.
• USB charging ports (Type A / Type C) on current G3 models for phones and accessories.
• Audible alarms on outage.
• Backed by APC's standard warranty: 3 years on the UPS and 1 year on the battery for the BE550G and BE850G2 (APC data sheets).

Frequently asked questions

Is the Back-UPS ES a pure sine wave UPS? No. The Back-UPS ES series outputs a simulated (stepped approximated) sine wave, which is fine for the desktop, networking, and POS loads it targets. If you have equipment that specifically requires pure sine wave, choose a higher APC series.

Can I add an external battery for longer runtime? No. The Back-UPS ES models are not designed for extended-runtime battery packs. For long runtime, step up to a line-interactive or online APC family.

What size do I need? Total the wattage of the equipment you want on battery, then choose a model whose watt rating comfortably exceeds it. Most single-PC-plus-network setups fit within the 330 to 540 W range these units provide.

Are these units new? Yes: new APC units, unless the listing says refurbished, shipped from Canada with the manufacturer warranty.

Is the battery user-replaceable? It varies by model. Some current G3 units have a non-user-replaceable internal battery; older models such as the BE550G and BE850G2 use replaceable cartridges (APCRBC110 and RBC17, per APC). Check the individual product page, and see our replacement-battery hub for the correct cartridge.
