Three Phase GST Hybrid Solar Inverter 8.5–12.5kW
Description
Three Phase GST Hybrid Solar Inverter
The Three Phase GST Series is a low-voltage hybrid solar inverter designed for solar-plus-storage systems requiring three-phase AC output. The series is available in 8.5kW, 10.5kW and 12.5kW rated-output models, providing options for larger residential loads and suitable small commercial energy-storage applications.
All three models operate on a 48V nominal battery platform with a 40–60VDC battery operating range. The inverter provides 400VAC three-phase output at 50/60Hz and uses pure sine wave output.
The series supports lithium batteries, lead-acid batteries and user-defined battery configurations. CAN and RS485 interfaces are available for communication with compatible battery management systems, while optional Wi-Fi/4G connectivity supports remote system monitoring.

Which Three-Phase GST Model Should You Choose?
Inverter selection should be based on actual load requirements, PV-array configuration, battery capacity and expected backup demand rather than inverter power alone.
8.5kW GST48-8.5K-P3
The 8.5kW model can be considered for three-phase residential systems and projects where the required continuous output remains below the larger 10.5kW and 12.5kW configurations. Its two MPPT inputs support up to 6.6kW + 6.6kW of PV array power according to the supplier catalog.
10.5kW GST48-10.5K-P3
The 10.5kW model provides additional output capacity for larger residential loads and suitable small commercial solar-storage applications. The catalog lists up to 7.5kW + 7.5kW of PV array power across its two MPPT inputs.
12.5kW GST48-12.5K-P3
The 12.5kW model is the highest-rated configuration in the current Three Phase GST Series. It is intended for projects requiring greater three-phase output capacity and supports up to 9kW + 9kW of PV array power across two MPPT inputs according to the supplier catalog.
Typical Applications
- Three-phase residential solar-plus-storage systems
- Large-home backup power systems
- Residential solar self-consumption projects
- Small commercial solar-storage applications
- Three-phase off-grid or backup systems
- Projects requiring scalable inverter capacity
For lower-power single-phase residential applications, see the Single Phase GST Hybrid Solar Inverter.
Battery Compatibility
The Three Phase GST Series operates on a 48V nominal battery platform with a 40–60VDC operating range. The supplier catalog lists lithium batteries, lead-acid batteries and user-defined battery configurations as supported battery types.
For LiFePO4 battery systems, the inverter and battery BMS may communicate through CAN or RS485. Exact compatibility should be confirmed against the selected battery model, voltage range, charge/discharge current and communication protocol before quotation.
Battery capacity should also be selected according to inverter power and actual backup requirements. A higher inverter rating does not automatically mean that any 48V battery configuration will provide sufficient discharge power.
For higher-capacity residential storage projects, see the GBP-L Wheeled LiFePO4 Battery.
PV Configuration
All three Three Phase GST models provide two MPPT inputs. The supplier catalog lists a 200–650VDC MPPT operating range and up to 800VDC maximum open-circuit voltage per PV input.
Before quotation, the PV string configuration should be checked using module Voc, operating voltage, temperature conditions, number of modules per string and total array power. The PV array should not be selected only from the inverter’s rated AC output.
Parallel Expansion
The Three Phase GST Series supports parallel operation of up to nine units according to the supplier catalog, allowing inverter capacity to be expanded for projects requiring greater system output.
Parallel system design should be confirmed according to the selected inverter model, battery-bank capability, AC load distribution and project requirements before ordering.
Monitoring and Communication
The inverter provides RS485, CAN, USB and dry-contact interfaces. Optional Wi-Fi/4G modules can be used for remote connectivity.
The supplier platform supports remote viewing of operating data and equipment status as well as remote control and parameter adjustment.
Charging and Energy Management
The Three Phase GST Series provides four charging strategies for different power-supply conditions:
- Mains Priority
- PV Priority
- Hybrid Mains & PV
- PV Only
Scheduled charging and discharging are also supported, allowing the operating strategy to be configured according to electricity-use requirements and applicable time-of-use electricity tariffs.
