Low-voltage cooking · OEM platform
Single- and two-zone induction cooktops for RV, marine, off-grid and energy-storage applications—configured for 12–48V DC projects.
Voltage range is only the starting point. Rated output, current, cable, protection and battery/BMS capacity are confirmed for every project.
Direct answer for project buyers
Joelwave supplies configurable low-voltage DC induction cooktops for RV, marine, off-grid and energy-storage projects. Confirmed models include a 24V / 1000W single-zone cooker, a 48V / 1500W single-zone cooker with a 36–60V operating range, and a 48V / 2500W two-zone cooker. Standard MOQ is 100 units and normal production lead time is approximately 15 days after the electrical configuration and order are confirmed.
OEM work can cover glass graphics, touch-control layout, DC cable and connector selection, packaging and documentation. Buyers should provide the battery voltage range, BMS ratings, intended zone use, cable and protection plan, destination market and certification requirements before requesting a sample. No third-party certification is currently available.
Two formats
01 · COMPACTCompact glass-top format for space-conscious RV, boat and mobile-kitchen layouts. Touch controls and a dedicated DC cable connection keep the integration direct.
02 · EXTENDEDA wider two-zone platform for installations that need more cooking flexibility. The electrical system and simultaneous-load requirement must be matched to the vehicle, vessel or battery bank.
Integration markets
Plan the cooktop around the house battery, inverter strategy, available counter space and ventilation path.
Confirm installation environment, electrical protection, cable routing and the destination market’s applicable requirements.
Coordinate voltage, BMS limits, peak current and usable battery capacity before selecting the final output.
Real engineering evidence
Control boards and induction coils must be selected for the confirmed input voltage, target output and thermal environment.
Active cooling and installation clearances are part of the product design—not an afterthought after the glass size is chosen.
Cable cross-section, connector, fuse or breaker and terminal design must be rated against maximum project current.
System architecture
A direct-DC induction cooktop takes power from the battery-side electrical system without first supplying the cooktop through an AC inverter. This removes one conversion stage from the cooking power path, but it does not automatically make every installation more efficient or more suitable. The correct choice depends on battery voltage, BMS current, cable length, DC protection, inverter capacity, appliance availability and the vehicle's complete electrical architecture.
| Decision point | Direct-DC cooktop | AC cooktop through inverter |
|---|---|---|
| Power path | Battery or DC bus → cooktop | Battery → inverter → AC cooktop |
| Suitable project | Electrical system designed around a confirmed DC voltage | Vehicle already designed around a sufficiently rated AC inverter |
| Key checks | Voltage window, BMS current, cable, DC fuse or breaker, disconnect and cooling | Inverter continuous and peak rating, AC circuit, battery load and cooling |
| Main advantage | Removes the cooktop's separate DC-to-AC conversion stage | Wider availability of standard household appliances |
| Main limitation | High-current DC engineering and voltage compatibility must be confirmed | Cooking depends on inverter capacity and the complete conversion path |
Selection principle: compare the complete electrical system, not only the appliance label. Joelwave does not publish a universal efficiency-saving percentage because wiring, battery conditions, electronics and operating patterns differ by project.
Confirmed platform scope
Engineering note: “12–48V” describes the configurable platform range and does not mean every finished unit automatically accepts every voltage. The confirmed configurations are 24V / 1000W and 48V / 1500W; the rated 48V product has a confirmed 36–60V DC operating range. Final maximum current, cable gauge, connector, fuse or DC breaker, accessible disconnect, ventilation and battery/BMS capacity must be approved before production or installation. No third-party certification is currently available; the applicable certification and compliance route must be evaluated for the destination market.

Buyer questions
The platform can be configured for DC systems within the 12–48V range. The exact operating voltage, rated output, cable, connector, current protection and control board must be selected and confirmed for each project.
Yes. The photographed development range includes compact single-zone and wider two-zone glass-top formats. Final dimensions, control layout and rated output are project-specific.
It is designed for direct-current integration, but a safe installation still requires confirmation of battery and BMS capacity, maximum current, conductor size, fuse or breaker, connector and ventilation.
Not automatically. Direct DC removes the cooktop's separate DC-to-AC conversion stage, but total system performance still depends on the cooktop electronics, battery voltage, current, cable length, voltage drop, thermal management and operating pattern. A project-specific comparison is required before making an efficiency claim.
No. A compatible direct-DC cooktop can operate without supplying that appliance through an AC inverter, but the RV may still need an inverter for other AC loads. The complete electrical architecture should be reviewed as one system.
Yes. The confirmed operating range for the rated 48V product is 36–60V, so 46–56V is within the product voltage window. The complete installation still requires confirmation of BMS current, cable, DC protection, connector, ventilation and intended load.
Sample orders can be discussed before a wholesale order. We first confirm the rated voltage, battery chemistry and capacity, BMS continuous and peak-current ratings, installation method, cable and connector requirements, delivery country and intended cooking load.
The cooktop should be installed with correctly rated DC conductors, over-current protection such as a fuse or DC breaker, and an accessible DC disconnect. Cable length, conductor cross-section, connector, ventilation clearance and protection ratings must be approved against the selected model and maximum current. Professional installation is recommended.
Runtime depends on usable battery energy, selected power level, conversion losses and the battery/BMS discharge limit. A practical estimate is usable battery watt-hours multiplied by system efficiency, then divided by the cooktop’s actual average wattage. We confirm the calculation against the customer’s battery specification rather than publishing one universal runtime.
Induction-compatible ferromagnetic cookware is required. Cookware diameter and performance should be validated against the final cooking-zone configuration.
Yes. For qualified projects we can coordinate glass graphics, touch-control layout, cable and connector selection, packaging, manuals and production evidence.
The project price changes with voltage, output, zone count, glass size, electronics, wiring, connector, certification, packaging and order quantity. We quote confidentially to protect distributor margins.
