Peak shaving and demand charge reduction for factories, warehouses, and processing facilities requiring 8-10kW continuous power.
Whole-home backup for luxury properties with high consumption appliances, EV charging, and critical medical equipment.
Irrigation pump stations, grain drying operations, and cold storage facilities requiring reliable off-grid power.
Remote base stations, rural clinics, and island microgrids requiring autonomous energy management with grid fallback.
Yes. The QB series features battery-less operation mode, allowing direct PV-to-load power during daylight hours. This high-efficiency logic eliminates the need for immediate battery investment while maintaining the flexibility to add LiFePO4 or lead-acid storage later as budget allows. The system seamlessly transitions to grid power when solar generation is insufficient.
Dual PV inputs allow connection of two separate solar arrays with different orientations, tilt angles, or panel specifications—each with independent MPPT optimization. This is ideal for East-West roof configurations, partial shading scenarios, or mixed panel installations. Each channel supports up to 5,400W (90-450Vdc), maximizing energy harvest throughout the day regardless of sun position.
The QB series intelligently manages two separate AC output circuits. Primary outputs (critical loads: refrigeration, medical equipment, security) receive priority power, while secondary outputs (non-essential loads) can be automatically shed during low battery or high demand to extend backup duration. This smart load management ensures mission-critical systems remain operational during extended grid outages.
Yes. The QB series includes built-in BMS (Battery Management System) communication protocols for modern LiFePO4 battery banks, enabling auto-activation, cell balancing monitoring, and safety protection integration. It also supports traditional lead-acid, gel, and AGM batteries. The 48V nominal architecture is optimized for current lithium battery standards.
The inverter supports multiple monitoring methods: (1) RGB LED status ring for local visual operation mode indication; (2) Optional WiFi or GPRS modules for smartphone app control; (3) RS232/RS485 interfaces for BMS integration and SCADA system connectivity. Remote capabilities include real-time power flow monitoring, historical data logging, parameter adjustment, and push notifications for faults or maintenance alerts.
