Harness solar energy with ease—compatible with 12V-59VDC solar panels (max 800W output). Featuring MPPT (Maximum Power Tracking) technology, it optimizes charging efficiency by real-time matching the solar panel’s output with the battery’s voltage, even in changing weather conditions. Note: Solar panels are sold separately.
Manage your power station anytime, anywhere via the MARSTEK App (compatible with Android 6.0+ and iOS 12.0+). Connect via Bluetooth or Wi-Fi to track energy production/usage in real time, adjust charging/discharging settings, and monitor device status dynamically. The app supports server selection (EU, China, US&Non-EU) for seamless data synchronization.
- Charging Modes: Choose "Charge and then discharge" (prioritize battery charging, then supply power to micro inverter) or "Pass through" (directly power micro inverter with surplus solar energy stored in the battery).
- Discharging Modes: Set custom time periods and power levels, or use "Adaptive" mode to intelligently match household load based on CT-collected data (CT manual sold separately).
Built with multiple safety protections to prevent hazards. The power station remains cool during operation, and all materials comply with EU RoHS environmental standards. It also features proper disposal guidelines to support sustainable recycling.
