OUPES 2400

Overview

The OUPES 2400 is the lightest 2 kWh-class station in this index at 20.7 kg, roughly a third less than the wheeled units it competes with on capacity. OUPES publishes 2,232 Wh of LFP rated above 3,500 cycles to 80%, and 2,400 W rated output with a 5,000 W peak, explicitly through a pure sine wave inverter. All five AC outlets are plain NEMA 5-20R, so there is no RV shore-power receptacle. Its clearest limitation is charging: input arrives through paired 7909 and Anderson ports rated 2 x 200 W for AC and 2 x 240 W for solar, so 400 W and 480 W respectively, which is low for the capacity and gives the published 5.5-hour full recharge. There is no documented battery expansion and no UPS switchover figure.

Variant note: Base standalone OUPES 2400 unit. Distinct from bundles pairing it with 240 W solar panels, whose panel specifications appear in separate blocks on the same product page and are not part of this entity. Also distinct from the OUPES Exodus 1200, which is separately indexed.

Data note: All values are taken verbatim from the official oupes.com product page specification tables on 2026-07-31. Those tables are segmented per bundled item; only the blocks marked for the OUPES 2400 unit were used, and the 240 W Solar Panel blocks (which carry their own weight, dimensions and warranty) were deliberately excluded. MANUAL NOT USABLE: an official OUPES user manual PDF exists on the manufacturer's own CDN and is recorded as officialManualUrl, but its text layer uses a subset font with no valid character mapping and extracts as garbled glyphs, so not a single value in this record is sourced from it. The record is therefore held at medium confidence despite a manual existing. CYCLE-LIFE CONFLICT PRESERVED: the specification table states 'Cycles > 3,500 cycles to 80%' while the marketing highlights on the same page state 'retaining over 70% capacity after 4,000 charge cycles'. These differ in both count and retention threshold and cannot be reconciled; the specification table is recorded and the marketing figure is preserved here rather than merged. SOLAR RECHARGE CLAIM NOT RECORDED: the highlights also claim a full charge 'as quickly as 3 hours with solar input', which does not reconcile with the stated 2 x 240 W (480 W) solar ceiling against 2,232 Wh; that claim is excluded and only the AC figure is recorded. acInputW=400 and solarInputW=480 are the sums of the two identical stated ports in each case, which the page presents as '2*200W' and '2*240W'. The 5.5-hour AC recharge is consistent with 400 W into 2,232 Wh, which supports both figures. WEIGHT: the specification table gives 45.5 lbs (20.7 kg) while the page highlights say 45.6 lbs; the spec table is recorded and the difference is rounding. solarInputVoltageRange is null because no PV voltage window is published for the unit (the 24.6 V open-circuit figure on the page belongs to the bundled panel, not the station). expandableBatterySupport=false is a negative finding from a complete specification table that lists no expansion port or expansion battery. upsEpsMode='unknown', passThroughCharging='unclear', mpptPresent and appControl null: no official statement was located for any of these.

Use cases

• Home backup for essential loads up to 2,400 W continuous
• Camping and road trips where 2 kWh at 20.7 kg is still liftable
• Sensitive equipment needing documented pure-sine output
• Users who value a long warranty over fast charging or expansion
