Description
Key Features
-
Massive Single-Unit Capacity: Available in 280Ah (14.3kWh), 300Ah (15.3kWh), and 320Ah (16.3kWh) options. A single unit provides enough energy to power a typical household through the night, saving space and installation time.
-
High Power Output (10KW): Supports a robust discharge current of up to 200A (model dependent), delivering 10KW of power. This is perfect for pairing with 8KW-12KW hybrid inverters to run heavy appliances like central AC and pumps.
-
Built-in Smart WiFi: Integrated WiFi module enables remote monitoring, fault diagnosis, and OTA firmware updates directly via the MUST App, providing peace of mind without extra accessories.
-
Intelligent Auto-Recovery: Features smart undervoltage recovery logic, allowing the battery to automatically reboot and resume operation when conditions are met, ensuring uninterrupted power supply.
-
Floor-Standing Design: The robust SPCC metal enclosure (260*733*633mm) is designed for stable floor installation, fitting neatly in garages or utility rooms without requiring wall reinforcement.
-
Scalable Expansion: Supports parallel connection of up to 15 units, allowing for massive system scaling up to 245kWh for commercial or industrial backup.
-
Universal Compatibility: Equipped with CAN2.0, RS485, and RS232 interfaces, ensuring seamless communication with mainstream inverter brands.
Applications
-
Whole-Home Backup: One unit covers most needs; two units offer grid-independence luxury.
-
High-Consumption Households: Ideal for homes with EVs or electric heating that require high power output (10KW).
-
Small Commercial: Parallel multiple units to power servers, offices, or small shops.
