The STG-PH3600-48 is a highly adaptable and efficient bidirectional grid-tie inverter, designed for photovoltaic (PV) systems with integrated battery storage. It intelligently manages solar energy production to maximize self-consumption, store excess energy in batteries, and feed surplus power into the grid when needed.

This inverter provides a reliable and flexible energy solution, seamlessly balancing energy flow between PV systems, batteries, and the grid to reduce electricity costs and ensure energy independence.

Core Features:

• Bidirectional Energy Flow:
  • Automatically balances energy production and consumption.
  • Optimizes self-consumption by prioritizing 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 SolarPowerMonitor mobile app 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 maximizing 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.
