The TENTEK Tribune Series Energy Controller is a cutting-edge solution that integrates an MPPT battery controller and energy management system into a single, efficient unit, providing a comprehensive solution for microinverter storage systems. It addresses the challenge of storing excess solar energy into batteries, which traditional microinverters cannot achieve, and allows for flexible control of the microinverter's output to the main grid.
Function Description:
The Tribune-EMS controller supports both on-grid and off-grid capabilities, offering flexibility to switch between grid-connected and off-grid operations, thereby expanding energy options and promoting greater energy independence. It manages the flow of energy from PV panels, microinverters, batteries, and the grid, optimizing energy usage for residential solar power systems. The controller is designed to work in conjunction with designated microinverters to create a hybrid solar storage system.
Key functionalities include:
- MPPT Battery Control: Integrates Maximum Power Point Tracking (MPPT) for efficient battery charging from PV panels.
- Energy Management System: Manages energy flow between PV, battery, microinverter, and grid to optimize consumption and reduce reliance on the main grid.
- Grid Interaction: Allows for feeding excess solar energy back into the grid and drawing power from the grid when solar generation is insufficient.
- EPS Load Connection: Supports connection of essential loads (Emergency Power Supply) to ensure continuous power during grid outages.
- Multi-communication: Features RS485, Bluetooth, or WiFi communication modules for real-time monitoring of battery operating status, energy system stability, and safety via the T-Shine cloud monitoring APP.
