Flexible Power Solutions for Every Situation

The Sky Charger is engineered to keep your batteries charged and your devices powered, regardless of grid availability. Whether you're at home, in your workshop, or off-grid, the Sky Charger adapts to your power needs with intelligence and reliability.

When the Power Grid is ON

Simply plug the Sky Charger into any standard 220V wall outlet using the included AC adapter. The intelligent charging system automatically detects your battery type and begins the optimal charging sequence. Perfect for everyday battery maintenance and preparation for unexpected outages.

When the Power Grid is OFF

The Sky Charger truly shines when the grid goes down, offering four distinct operating modes to maximize your available power resources:

• Solar Recharge Mode

Connect a solar panel (up to 300W, 50V max) to recharge your batteries directly from the sun. The advanced MPPT-like algorithm ensures maximum power extraction from your panels, even in suboptimal lighting conditions.

• Standalone Inverter Mode

Power small electronics and devices directly from your battery. The built-in 20W inverter provides 25kHz square wave output through a standard Euro outlet — ideal for charging phones, running LED lights, or powering small electronics during emergencies.

• Hybrid Mode (Solar + Inverter)

The most versatile mode: run the inverter from your battery while simultaneously recharging the same battery from solar panels. This pass-through charging capability allows for extended off-grid operation without interruption.

• Solar Direct Mode

Run the inverter directly from solar panels with no battery required. When solar input is sufficient (≥12V), you can power devices directly from the sun — perfect for daytime applications where battery storage isn't needed.

  Quickly restart the firmware in case of any anomalous behavior — returns the system to a known good state without losing settings.

• Advanced Protection Systems

  The Sky Charger incorporates multiple layers of protection to safeguard your batteries, the unit itself, and connected devices:

  • Battery Protection

    Reverse Polarity Protection	Prevents damage if battery cables are connected backwards
    Over-Voltage Protection	Stops charging if voltage exceeds safe limits
    Over-Current Protection	Limits charge current to manufacturer-safe levels
    Low Battery Cut-Off	Automatically disconnects inverter when battery voltage drops too low

  • Inverter Protection

    Over-Current Protection

    Shuts down inverter during short circuits or overloads

  • Solar Protection

  Solar Over-Voltage Protection

  Prevents damage from panels exceeding 50V input limit

• Premium Hardware Design

  • Active Cooling System

  Two high-quality cooling fans work in conjunction with large aluminum heatsinks to maintain optimal operating temperatures, ensuring reliable performance even during extended charging sessions.

  • Thermal Management

  The intelligent thermal system dynamically adjusts fan speed based on temperature, balancing cooling needs with noise reduction for quieter operation.

  • 3D Printed Enclosure

  The Sky Charger features a unique, stylish enclosure created through advanced 3D printing technology. The smooth curves and modern aesthetic set it apart from conventional, boxy power devices. This is not your typical black box.

  • Compact Form Factor

  With dimensions of 19 × 21 × 14 cm and weighing approximately 1 kg, the Sky Charger is portable enough for field use yet substantial enough to feel durable and well-made.
