An English-language B2B solution for a French tender requiring 2,100Wh+ capacity, 3,600W continuous output and an 18kW peak: EP5000iL as the core unit, EP3600iL as the compact alternative, EP12000iL to cover the peak requirement, with honest gap analysis on weight, IP rating, peak duration and a full RFQ checklist.
A French procurement team is sourcing mobile energy storage for professional duty across construction sites, emergency services, firefighting, military and event operations. The stated specification is demanding: at least 2,100 Wh of battery capacity, at least 3,600 W of continuous AC output, an 18,000 W short-duration peak, 230 V AC / 50 Hz pure sine wave output, a complete unit under 20 kg including battery and housing, protection rated IP54 or better (IP65 preferred), a full charge in three hours or less, discharge capability from −20°C to +60°C, low-noise (ideally fanless) operation, and professional-grade electrical protection — all supported by verifiable test results, in particular peak power duration and overload capability.
This solution is built exclusively on DRIVELONG's current production catalog (Suzhou Drivelong Intelligence Technology Co., Ltd., a portable power station manufacturer with 19 years of power generation experience, 120+ patents and full EU/US certification). It presents the closest real products to each requirement, states openly where the specification and the catalog diverge, and defines what must be confirmed through an RFQ and laboratory test reports before contract award. No specification in this document has been adjusted to make a product appear compliant.
Solution Overview
The recommended architecture pairs one core unit with an optional flagship upgrade:
Core recommendation — EP5000iL Smart Mobile Power Station. It is the only unit in the catalog whose published specification sheet covers nearly every requirement in the French tender: a 3,430 Wh LiFePO4 battery, 5,000 W continuous and 10,000 W peak AC output, 220/230/240 V single-phase output at 50/60 Hz with a pure sine waveform (THD<3%), a full AC charge in 1.2 hours, discharge operation from −20°C to +60°C, a documented UPS transfer time of 10 ms or less, and third-party certifications (RoHS, CE, UN 38.3) with a 5-year warranty. It exceeds the required continuous output by roughly 39%, which protects the margin when loads are inductive or start simultaneously.
Compact alternative — EP3600iL High-Power Mobile Power Station. For buyers who want to sit exactly at the 3.6 kW class, the EP3600iL delivers 3,600 VA rated / 7,200 VA peak output from the same 3,430 Wh LiFePO4 platform, with the same stackable expansion to 109 kWh, a patented four-wheel chassis and patented heat dissipation and protection technology designed for harsh environments.
Peak-power specialist — EP12000iL Flagship. The 18,000 W peak requirement is the one figure no compact unit in the catalog reaches. The EP12000iL is the only production model rated above it: 24,000 VA peak and 12,000 VA continuous (12 kW three-phase, 11 kW single-phase, 10 kW split-phase), a 7,680 Wh battery, a 70-minute full charge and a built-in 22 kW EV charger. Where 18 kW-class motor starts are non-negotiable, this is the realistic basis — accepting that it is a larger, industrial-class machine, not a sub-20 kg portable.
Recommended Products and Specification Comparison
The table below compares the three candidate units against the tender requirements, using only figures published in the product records. Cells marked "to be confirmed" are not stated in the current product documentation and must be verified through the RFQ process described below.
Tender requirement | EP3600iL | EP5000iL (recommended) | EP12000iL |
|---|---|---|---|
Battery capacity ≥ 2,100 Wh | 3,430 Wh LiFePO4 — met | 3,430 Wh LiFePO4, 67 Ah (51.2 V), 5,000+ cycles to 80% — met | 7,680 Wh LiFePO4 — exceeded |
Continuous AC output ≥ 3,600 W | 3,600 VA rated — at threshold | 5,000 W rated — met with margin | 12,000 VA rated; 11 kW single-phase, 12 kW three-phase — exceeded |
Peak output ≥ 18,000 W | 7,200 VA — below | 10,000 W — below | 24,000 VA peak; 24 kW parallel output — exceeded |
230 V AC / 50 Hz | To be confirmed | 220/230/240 V, 50/60 Hz — met | To be confirmed (three-phase / split-phase modes published) |
Pure sine wave | To be confirmed | Pure sine wave, THD<3% — met | To be confirmed |
Total weight ≤ 20 kg | Not published — see analysis | 49 kg (555 × 430 × 420 mm) — not met | Not published — larger class |
Protection ≥ IP54 (IP65 preferred) | Not published | Unit IP53 / battery pack IP66 — partial (see analysis) | Not published |
Full charge ≤ 3 hours | 80% in 1 hour — met | 1.2 h full (AC 3,000 W); 2.5 h via 1,600 W solar — met | 70 minutes full — exceeded |
Discharge −20°C to +60°C | Not published | Discharge −20°C to +60°C; charge 0°C to +45°C — met | Not published |
Electrical protection & certification | 5-year warranty; app monitoring | UPS transfer ≤ 10 ms; RoHS, CE, UN 38.3; 5-year warranty | Built-in 22 kW EV charger; 5-year warranty |
All three units support stackable battery expansion: 31 extra packs take the EP3600iL and EP5000iL to 109 kWh and the EP12000iL to 372 kWh, which matters for multi-day emergency or event duty without refueling.
Requirement-by-Requirement Analysis
Capacity and continuous output: met
Every candidate clears 2,100 Wh by a wide margin. On continuous output, note one precision: the EP3600iL is rated at 3,600 VA, which equals the 3,600 W requirement only at a power factor of 1.0; for mixed inductive loads the effective watt figure will sit slightly lower. The EP5000iL avoids this ambiguity with a 5,000 W rating and is therefore the safer basis for a tender that fixes the threshold at 3,600 W. The EP12000iL provides 11 kW single-phase where multi-unit sites need headroom.
The 18,000 W peak: the defining gap, with a real answer
No sub-20 kg or 3.6–5 kW class unit in the catalog delivers an 18,000 W peak. The published peaks are 7,200 VA (EP3600iL), 10,000 W (EP5000iL) and 24,000 VA (EP12000iL). The realistic options are therefore:
Option A: Specify the EP12000iL, whose 24,000 VA peak exceeds the requirement, if the peak figure is a hard pass/fail criterion. This accepts a larger, heavier industrial unit and higher acquisition cost.
Option B: Keep the EP5000iL (10,000 W peak, 5,000 W continuous) and reduce the actual peak demand at source — staged starting of motors, soft-starters on compressors and pumps, or splitting loads across two EP5000iL units, which can also be paralleled for 10 kW continuous output without a parallel kit. This suits sites where the 18 kW figure was written as a safety allowance rather than a measured load.
Option C: Request an OEM/ODM evaluation. DRIVELONG's business model includes OEM and ODM programs, so a modified peak specification can be assessed as an engineering question rather than rejected outright; feasibility, however, must come from DRIVELONG's engineering team, not from this document.
In all three options, one point must be settled in writing before award: peak ratings in the catalog are short-duration surge figures, and peak duration and overload capability are not stated in the current product records. They must be evidenced by laboratory test reports (see the verification section below).
Weight: the specification no catalog product can meet
A complete unit under 20 kg that also delivers 2,100 Wh and 3,600 W continuous output does not exist in this catalog — and the honest engineering position is that it does not exist in this product class. The closest documented figure is the EP5000iL at 49 kg; the 3.6 kW-class BP3600, for reference, weighs 42 kg without wheels and 45 kg with wheels and handle. Battery chemistry and inverter hardware set this floor: buyers should treat "≤ 20 kg" and "≥ 2,100 Wh / ≥ 3,600 W" as mutually exclusive until battery energy density changes. The practical trade-offs are: (a) accept a 42–49 kg class unit on the patented four-wheel chassis with large-diameter rollers, which the EP series is explicitly built around; (b) split the system into a base unit plus separate stackable battery packs so no single object exceeds the handling limit; or (c) reduce the capacity/output requirement if 20 kg is a hard transport constraint. We recommend confirming which constraint — mass per object or total system mass — actually governs the tender.
Ingress protection: close, but split between unit and battery
The EP5000iL is documented as IP53 at unit level and IP66 at battery pack level. IP53 sits one grade below the required IP54 on the water-ingress scale (spraying water versus splashing water from any direction), while the IP66 battery pack exceeds the preferred IP65. A whole-unit IP65 rating is not published for any catalog model. For construction and firefighting duty, ask DRIVELONG to state whether a sealed variant or configuration change can lift the unit-level rating, and to provide the actual IP test reports for both the unit and the battery pack.
Charging and temperature: met, with one cold-weather caveat
The three-hour full-charge requirement is comfortably met: 1.2 hours on AC for the EP5000iL, 70 minutes for the EP12000iL, and 80% in one hour on the EP3600iL. Discharge temperature on the EP5000iL matches the preferred window exactly at −20°C to +60°C. The caveat applies to charging: the documented charging window is 0°C to +45°C, so in sub-zero conditions the unit must be brought above 0°C before fast charging — relevant for winter construction sites and alpine emergency deployment. This behavior should be confirmed and, if required, a battery self-heating option requested in the RFQ.
Noise and cooling: active cooling is documented, silence is not claimed
The EP5000iL uses dual-channel cooling; no catalog model is claimed as fanless, and no sound pressure levels are published. Compared with any fuel-driven generator the acoustic profile is inherently far lower, but for indoor firefighting use or night event work the actual dB(A) figures at rated load must come from test data. Ask for measured noise values and whether an eco/low-fan mode exists before writing the acoustic clause.
Electrical protection and ruggedness
Documented professional features on the recommended platform include the UPS transfer time of 10 ms or less (connected loads keep running when utility power drops), intelligent wireless monitoring with smartphone app control, patented heat dissipation and protection technology rated for harsh environments (EP3600iL/EP5000iL platform), a metal housing with an integrated automatic fire suppression system on the BP3600 where that level of fire protection is required, and LiFePO4 cells rated for 5,000+ cycles to 80% capacity. Certified compliance on the EP5000iL covers RoHS, CE and UN 38.3 (transport), with a 5-year warranty across the range.
Application Scenarios
Construction sites: the EP5000iL runs high-power tools and site machinery loads at 5,000 W continuous with a four-wheel chassis for daily repositioning; expansion to 109 kWh covers multi-week sites without a fuel logistics chain.
Emergency services and firefighting: the IP66-sealed battery pack, −20°C discharge capability and sub-10 ms UPS transfer suit command-post and rescue-equipment power; the firefighting-specific requirements (heat exposure ratings, any ATEX-type certification) are not published and must be confirmed before specifying the unit for direct firefighting duty.
Events: silent battery operation replaces generator noise for stages, catering and broadcast; the 70-minute recharge of the EP12000iL enables same-day turnaround between event days.
Military and institutional buyers: the platform's stackable architecture, app-based fleet monitoring and UN 38.3 transport certification support deployment logistics; military-specific standards (MIL-STD, EMP, CBRN) are outside the published scope and would be an OEM/ODM discussion.
Verifiable Test Documentation: What Exists Today and What Needs an RFQ
Available today for the EP5000iL, on request with the quotation: the published specification sheet (all figures cited above), CE, RoHS and UN 38.3 certification, and the 5-year warranty terms.
Not contained in the product records and therefore to be evidenced during the RFQ, in line with the tender's own requirement that all performance specifications be supported by verifiable test results:
Peak power duration curves at the stated peak rating; overload capability and trip behavior (duration and load percentage before protective shutdown); IP test reports for the unit and the battery pack separately; measured noise levels at rated and eco load; discharge capacity retention at −20°C; battery cycle-life test reports; and, for the EP3600iL and EP12000iL, the published voltage, waveform, weight, IP and temperature figures that the current records do not state.
Next Steps: RFQ Checklist for the French Buyer
To move from this solution to a compliant award, we recommend the following request list, addressed to DRIVELONG's export team:
Confirm the intended basis unit (EP5000iL for the balanced specification; EP12000iL if the 18 kW peak is a hard criterion) and request the full laboratory test reports listed above, including peak duration and overload curves.
Request a written statement of the achievable unit-level IP rating and whether an IP54/IP65 variant exists or can be configured.
Confirm the transport and handling constraint: whether the 20 kg limit applies per object or per system, and evaluate the base-unit-plus-battery-pack split accordingly.
Ask for measured noise data and any low-noise operating mode applicable to indoor and night use.
Confirm French/EU market documentation: CE scope (LVD, EMC), grid-relevant declarations, and any additional certification needed for emergency-services procurement in France.
Request OEM/ODM terms in parallel if Option C (customized peak specification) is to be evaluated, including MOQ and lead time for modified units.
