Description

Efficient 3.6kw hybrid grid-tie inverter for smart solar and battery energy management.

Maximise your solar energy with the Stellar 3.6kW 48V hybrid grid-tie inverter. It intelligently manages solar production, stores excess in batteries, and feeds surplus power into the grid. Reliable and flexible, it helps reduce electricity bills while providing energy independence for your home or business.

Compatibility

This inverter is suitable for 48V flooded and sealed GEL/AGM lead-acid as well as Lithium batteries, with pre-defined charging programs for each type. Whether you need reliable off-grid power, grid-tie functionality, or battery backup for energy security, this inverter offers the perfect balance of efficiency, flexibility, and advanced technology.

Key functions

  • Bidirectional Energy Flow: 
    • Automatically balances energy production and consumption.
    • Optimises self-consumption by prioritising solar energy and battery usage.
    • Draws from the grid only when PV and battery power are insufficient.
  • Flexible Operation Modes: 
    • The STG-PH3600-48 operates in five distinct modes, offering a tailored solution for every scenario.
  • Feed Energy to the Grid:
    • Surplus PV and battery power is exported to the grid.
  • Match Load:
    • Powers the loads using PV and/or battery power without grid feed-in.
  • Battery Charge:
    • PV or grid energy charges the batteries while also supplying the load.
  • Standby:
    • The grid takes over load supply if the inverter encounters a fault.
  • Off-Grid:
    • Operates independently of the grid, supplying loads using PV and/or battery power only.
  • Dual MPP Trackers:
    • Supports two independent PV arrays for up to 98% solar energy harvesting efficiency.
  • IP65 Rated for Outdoor Use:
    • Durable and weather-resistant, this inverter is built to withstand harsh outdoor environments, providing long-lasting performance.
  • Wi-Fi Connectivity:
    • Access system settings and monitor energy parameters through the SmartValue mobile app (IOS and Android) for effortless remote management.

Additional Features

  • CT Clamp Integration:
    • Enables real-time monitoring of grid energy flow into the house, improving control of battery charge/discharge and maximising self-consumption.
  • User-Friendly LCD Display:
    • Displays essential system information, including power flow, voltage, and current inputs/outputs.
    • Provides intuitive access to configuration settings.
  • Peak Power Handling:
    • Supports peak loads of up to 6000VA for 10 seconds, ensuring reliable performance for demanding appliances.
  • Fanless design:
    • The fanless design ensures quiet operation while reducing potential maintenance needs.

Who Should Use the STG-PH3600-48?

  • This grid-tie inverter is ideal for homeowners and businesses looking to:
    • Maximise their use of renewable solar energy.
    • Minimise reliance on the grid while ensuring power stability.
    • Reduce energy costs through intelligent energy management.
