Product Overview
The Single-Phase Hybrid Inverter Series coordinates rooftop PV, a 48 V battery, utility power and backed-up loads in one configurable platform. Five output ratings allow system capacity to follow actual demand. Multiple charging priorities, scheduled charging and discharging, battery-less output capability and remote monitoring support both everyday solar self-consumption and practical outage preparation..

Technical Specifications
Recommended Applications
Residential solar self-consumption
Use daytime PV generation for household loads and store available surplus energy for later consumption.
Essential-load backup
Support selected household, office or retail circuits during utility interruptions when inverter and battery capacity are correctly sized.
Weak-grid and rural systems
Coordinate PV, battery and mains energy where utility supply is unstable or solar energy is the preferred source.
Small commercial and phased projects
Serve controlled commercial loads and reserve the option for later parallel capacity expansion.
Selection Guidance
Continuous and starting loads
Add simultaneous loads and check motor, pump, compressor and air-conditioner startup demand separately.
PV string design
Keep normal operation within 120–450 V and cold-weather open-circuit voltage below 500 V per MPPT.
Battery capability
Verify BMS protocol, charging and discharge-current limits, cable size and DC protective devices.
MPPT and expansion
Use separate MPPT inputs for dissimilar arrays and confirm all parallel-system accessories before ordering.
Installation and Maintenance
- Install in a dry, ventilated indoor location consistent with the IP20 protection level.
- Confirm polarity, PV voltage, battery parameters, cable sizing and AC/DC protection before energizing.
- Keep cooling inlets and outlets clear and maintain the required installation spacing.
- Review alarms, battery communication and PV input values during routine inspection.
- Check terminals for looseness, heat marks or discoloration after safe electrical isolation.
FAQ
Q:Can the inverter operate without a battery?
The series supports battery-less output and independent PV startup with load. A battery remains recommended where dependable backup is required.
Q:Which models provide two MPPT inputs?
GST48-8.5K-P1, GST48-10.5K-P1 and GST48-12.5K-P1 provide two MPPT channels.
Q:Can different lithium battery brands be connected?
Only after voltage, current limits, BMS communication protocol and approved compatibility have been confirmed.
Q:Is this product suitable for outdoor installation?
The inverter is rated IP20 and should be installed in a suitable protected indoor environment with adequate ventilation.
