System Integration & Working Principle

The Dfhy 3.6kw Solar Inverter acts as the central hub of a hybrid solar energy storage system, connecting PV modules, AC utility/generator, lithium/lead-acid batteries, and household loads (refrigerators, computers, televisions, etc.). It features three core working modes with customizable energy priority:
- Solar First Mode: Prioritizes solar energy to power loads; charges batteries with excess solar power, and supplements with grid power when solar energy is insufficient, maximizing renewable energy utilization.
- Grid First Mode: Takes the utility grid as the primary power source; uses solar energy to charge batteries first, and supplements load power with solar energy when grid power is insufficient, reducing electricity costs.
- Ups Mode: Ensures uninterrupted power supply for critical devices; switches to battery/solar power during grid outages, and automatically switches back to grid mode when power is restored.
The inverter also supports battery equalization function for lead-acid batteries, reversing sulfation and stratification to extend battery service life, with fully configurable equalization voltage, time, and interval parameters.

Easy Installation & Intuitive Operation

Simplified Mounting: Designed for vertical wall mounting on concrete/non-combustible surfaces with pre-drilled mounting holes and included expansion screws; requires 30cm of clear space around the unit for heat dissipation and wiring.
Standardized Wiring: Clearly labeled terminal blocks for AC input/output, PV input, battery connection, and BMS communication; supports standard cable gauges with dedicated crimp terminal requirements for safe, reliable wiring.
Plug-And-Play Accessories: Comes with all necessary installation hardware, and an optional smart communication stick for direct plug-in to the COM port for cloud monitoring without complex configuration.
User-Friendly Control: The front-panel LCD display shows real-time parameters (voltage, current, power, SOC, temperature, fault codes); four function keys (ESC/UP/DOWN/ENTER) enable easy access to over 40 configurable programs for personalized system settings.
Comprehensive Indicator Lights: AC, invert, charging, and fault LED indicators provide instant visual feedback on system status, with clear alarm and fault code definitions for quick troubleshooting.

Reliable Safety & Protection

Multi-Dimensional Protection: Full protection against overcharge, over-discharge, overvoltage, undervoltage, overcurrent, short circuit, overtemperature, overload, and reverse polarity; automatic fault recovery and six-time restart attempts for system stability.
Professional Electrical Safety: Complies with strict electrical safety standards; requires protective grounding connection and dedicated AC/DC breakers for installation; features high-voltage warning labels and a 5-minute power-off maintenance delay for operator safety.
Battery Safety: Dedicated battery overcurrent protection; prohibits charging of frozen batteries; supports lithium battery BMS communication for real-time battery status monitoring and protection.
Pv Safety: Prohibits PV terminal grounding; requires opaque covering of PV modules during daytime installation to avoid high-voltage hazards; with reverse polarity protection for PV input to prevent inverter damage.
