Solar-Storage-Charging Integrated Optimization Solution
Self-Generated, Self-Consumed · Surplus Power Not Fed to the Grid · No Grid-Connection Approval Required · Peak Shaving & Valley Filling
50%+ Annual Electricity Savings
Solar generation meets 60%–85% of annual power demand; peak shaving and valley filling significantly reduce peak-hour electricity costs.
Non-Grid-Connected, Approval-Free
Draws power from the grid only — never feeds power back to the grid, eliminating the need for complex grid-connection approval procedures and grid upgrades.
Grid Power as Backup Guarantee
Dual backup from storage plus grid power ensures uninterrupted agricultural production power even in extreme weather.
Six Core Advantages · Setting a New Benchmark for Agricultural Energy
Overall System Architecture
Uses a hybrid DC-coupled + AC-bypass architecture, made up of seven core subsystems, achieving coordinated optimization between energy supply and agricultural production.

Small-Scale LiFePO4 Storage System
5–20 kWh modular configuration, cycle life ≥5,000 times, built to withstand agricultural environments.
Non-Grid-Connected Energy Conversion System
Dedicated hybrid inverter with built-in anti-backflow protection, response time ≤10ms.
Smart Agricultural Load System
Loads classified by priority, enabling precise energy dispatch and intelligent load shifting.
Multi-Device Smart Charging System
Supports fast charging for agricultural drones, electric farm equipment, and other devices.
Integrated Smart Management Platform
Deep integration of energy management and agricultural control, enabling remote monitoring and intelligent scheduling.
