Technical Highlights

Key Specifications Overview

HC1066EH48L vs Traditional Solar Inverter

Self-Consumption / Zero Export Mode (Default Priority)

Daytime

Solar PV energy supplies household loads. Excess PV energy beyond load demand charges the 48V battery bank. The system does not export to the utility grid.

Nighttime / Low Solar

When solar power is unavailable or insufficient, the inverter discharges the battery to supply household loads. If the battery reaches its preset depth of discharge (DoD), utility grid power supplies the load demand.

Primary Benefit

The system maximizes solar self-consumption and prevents energy backflow into the utility grid.

Operating Modes

Grid-Tied Mode

The inverter synchronizes with utility frequency and exports surplus solar power, functioning as a standard grid-interactive single phase inverter.

Off-Grid Mode

Runs independently from battery and PV input, suitable for remote sites without utility connection.

Hybrid Backup Mode

Combines both: prioritizes solar and battery use during the day, switches to grid or battery seamlessly at night or during outages.

Comprehensive Protection and International Safety Standards

Safety is critical for residential solar energy systems.

The HC1060EH48L integrates multiple hardware and software protection functions.

These include:

• Grid overvoltage protection
• Grid undervoltage protection
• Overfrequency protection
• Underfrequency protection
• Battery overcurrent protection
• PV reverse polarity alarm
• Output short circuit protection
• Overload protection
• Insulation resistance monitoring
• Ground fault protection
• Residual Current Monitoring Unit (RCMU)

The inverter complies with international safety and EMC requirements, including:

• IEC 62109-1
• IEC 62109-2
• IEC/EN 61000 series
• EN 62920
• IEC 62321

These standards ensure reliable operation in global solar markets.
