Official HOULI product image shows the 12V DC to 120V AC / 60Hz variant. The large 8000W housing mark is peak power; continuous power is 4000W. Supplied accessories must be confirmed in the order specification.
U.S. Configuration Matrix
One model page covers the reviewed 12V and 24V input options. The ordered voltage, interfaces and current listing document still require confirmation.

Product Configuration and Supply Review
These statements distinguish verified model facts from items that must be fixed in the quotation and packing specification.
Safety protection
The source pages require suitable cables and protection devices and warn against operation above the continuous rating. Exact built-in protection thresholds and configuration-specific fuse or cable values must be confirmed from the current manual before installation.
Battery compatibility
Available 12V and 24V input versions must match the nominal battery system. Battery chemistry, BMS limits, usable capacity, discharge current and runtime remain system-level checks; no universal battery compatibility is claimed.
OEM / ODM support
For qualified programs, HOULI can review private-label branding, rating labels, manuals, packaging, barcodes, voltage configuration and socket requirements. Each item is subject to technical and order confirmation.
Packaging status
Packaging format, carton data and market labels are Pending Confirmation for the quoted configuration.
Accessory status
Remote control, DC cables, fuses and other supplied accessories must be listed in the quotation or packing specification; product photography is not an automatic packing-list commitment.
Product Role and Specification Boundary
HLWR0040E is rated at 4000W continuous and 8000W peak. The high DC current associated with this power tier makes battery capability, conductor design, protective devices, cable length, cooling and duty cycle essential parts of the quotation review.
The Intertek Authorization to Mark lists this model under Control No. 5031724 for UL 458 and CSA C22.2 No. 107.1. Confirm current listing coverage for the exact 12V or 24V input, 120V AC output and ordered interface configuration before quotation or compliance approval.
Battery-system fit
Choose the ordered 12V or 24V DC input configuration to match the confirmed battery architecture.
Continuous and startup load
Compare simultaneous operating demand with the continuous rating, then check startup demand separately against peak power.
Installation planning
Cable length, conductor size, fuse protection, mounting clearance and ventilation must be reviewed for the final configuration.
Market documentation
Output configuration, socket layout and required listing documents must be confirmed for the destination market.
Selection Checks Before Ordering
Use these checks to prepare the technical brief. They do not replace configuration-specific documentation or installation review.
Confirm continuous load
Add the wattage of equipment expected to operate at the same time. Keep the result below the continuous rating with suitable engineering margin.
Check startup demand
Motors, compressors and some power supplies can draw more power during startup than during steady operation.
Match the DC input
The ordered input configuration must match the nominal battery platform. Never connect a 12V input version to a 24V battery system.
Verify AC requirements
Confirm 120V AC, 60Hz and the required U.S. socket arrangement for the equipment before ordering.
Plan cables and protection
Final cable and fuse selection depends on DC current, cable length, installation method and configuration-specific documentation.
Review ETL scope
Request the current listing document for the exact model, DC input configuration, AC output and intended use before approval.
Applications to Evaluate
These links provide system-planning questions. They are not automatic model recommendations or customer case studies.
Documentation for Technical Review
Use the current English catalog for the published comparison values. Request model- and configuration-specific documentation before installation or procurement approval.
Product Selection FAQ
What are the continuous and peak ratings of HLWR0040E?
HLWR0040E is rated at 4000W continuous power and 8000W peak power. The peak figure is for short startup demand and is not the continuous operating rating.
Can HLWR0040E be ordered for either 12V or 24V batteries?
HOULI source pages show separate 12V DC and 24V DC versions for this model family. The input version must match the battery system, and the exact 120V AC / 60Hz configuration must be confirmed in the quotation.
Is HLWR0040E ETL Listed?
The Intertek Authorization to Mark lists HLWR0040E under Control No. 5031724. Request the current document and confirm coverage for the exact electrical and interface configuration being ordered.
Which high-power truck, fleet or backup loads can this inverter run?
Model fit depends on the combined continuous load, startup demand, duty cycle and battery system. Submit the actual equipment list for engineering review instead of selecting from appliance names alone.
