Looking for a compact solar panel for a portable power station, charge controller or small off-grid kit? A short KANK Solar factory video shows a compact panel marked 188 × 290 × 23 mm. The practical question is not only whether the panel fits a small installation, but whether its electrical output matches the controller, battery or power station you already use.
Video frame: the displayed product size is 188 × 290 × 23 mm. Please contact KANK Solar to confirm the electrical specification for your project.
What the video confirms
- The product is a compact black solar panel shown in a KANK Solar workshop.
- A cable is visible on the panel during the factory demonstration.
- The on-screen dimension is 188 × 290 × 23 mm.
What must be confirmed before you order
Panel dimensions do not tell you the charging power. Before choosing a quantity or connector, ask for the panel datasheet and confirm:
- Rated power (Wp), Voc, Vmp, Isc and Imp;
- cell technology, weight and operating-temperature range;
- cable length, connector type and polarity;
- water-resistance, certification, MOQ and packaging requirements.
These values are to be confirmed for the panel shown in the video. KANK Solar can match the specification to your battery and application before quotation.
How to match this compact panel to your system
1. MPPT charge controller
Send your battery voltage (12 V, 24 V, 36 V or 48 V), the controller model and the planned number of panels. Review the KANK Solar MPPT charge controller range and the 12V/24V/36V/48V sizing guide before choosing a configuration. The controller must stay within its PV input-voltage and charging-current limits, including the higher open-circuit voltage that can occur in cold weather. A physically small panel is not automatically suitable for every MPPT controller.
2. PWM charge controller
With PWM, the panel's nominal voltage needs to match the battery system more closely. See the PWM charge controller range when a lower-cost 12V or 24V system is being evaluated. Do not select a panel from its size alone; confirm the nominal voltage and current first. If you are replacing an existing panel, send a photo of its label so we can check the replacement more quickly.
3. Portable power station
Check the power station's PV input-voltage range, maximum input current, maximum solar charging watts and connector/polarity. For a 300 W / 307 Wh reference system, see the KK7009 portable power station and the broader portable power station range. If you are considering a 300 W / 307 Wh portable power station, send the exact model and its PV-input label. We will confirm whether one panel, multiple panels or a different panel configuration is appropriate.
Who benefits from a compact panel?
A compact format can help when roof, balcony, vehicle or field-kit space is limited. Typical inquiries include emergency charging, outdoor work kits, small monitoring equipment and portable backup systems. Final suitability depends on the load, daily energy target, sunlight hours and the controller or power station input-not on the panel's footprint alone.
Common questions
Does 188 × 290 × 23 mm indicate the panel's wattage?
No. The video confirms the physical dimensions only. Rated power and electrical values must come from the product datasheet.
Can I connect the panel directly to a battery?
Use a suitable charge controller unless the receiving device has its own approved solar-charge control. Direct connection can overcharge or damage a battery.
Will it work with every portable power station?
No. Compare PV voltage, current, maximum input watts and connector polarity with the power station manual before connecting.
What should I include in an inquiry?
Tell us the destination country, battery voltage, load or equipment, desired daily energy, quantity, installation space and any connector or label photos. We can then recommend a panel/controller combination and provide a quotation based on confirmed data.
Next step: send the details for a matched recommendation
To reduce back-and-forth, include the destination country, battery voltage, controller or power-station model, PV label photo, panel quantity and available installation space.
