How Three Phase Hybrid Energy Storage Inverter Works

The whole unit relies on a bidirectional AC-DC conversion topology to realize bidirectional energy flow, with three major circuits working in coordination: the PV DC circuit, battery DC circuit and three-phase AC circuit.

PV DC Circuit: Four independent MPPT units track the maximum power point of PV modules in real time and collect DC power generated by photovoltaic panels.

Bidirectional Main Conversion Circuit: The core power mainboard completes DC↔AC bidirectional conversion. The DC power from PV is boosted and inverted into 380V three-phase industrial AC for loads; surplus power is stepped down via DC-DC and stored in high-voltage lithium iron phosphate batteries. During off-peak electricity periods, AC power from the grid is rectified into DC to charge the batteries.

Grid-tied / EPS AC Circuit: Under normal grid-tied operation, the unit synchronizes grid voltage and frequency to output stable three-phase industrial power. In case of grid faults, anti-islanding protection is activated to quickly disconnect from the utility grid and switch to the off-grid EPS circuit, where the battery independently supplies steady three-phase power.

Control & Communication Circuit: The main control chip collects real-time voltage and current data of PV, batteries and the grid to dynamically adjust charging and discharging power, and supports unbalanced three-phase output. Multiple protective functions including AFCI arc detection, lightning protection and reverse connection monitoring work continuously to detect abnormalities. Operating data is uploaded to the HNA APP via WiFi, 4G and other channels for intelligent management and control.
