• Stable backup power during grid outages
• Battery storage flexibility
• Outdoor installation capability
• Intelligent energy monitoring

The HC1040EH48L addresses these requirements through an integrated hybrid architecture.

It works as a:

• Solar inverter
• Battery charger
• Backup power controller
• Energy management device

This makes it an ideal 48V hybrid solar inverter for home energy storage applications.

Technical Specifications

Key Features

Solar Input Capability with Dual MPPT Technology

Maximized Solar Harvesting Under Different Conditions

The HC1040EH48L solar power inverter has two independent MPPT channels. They support up to 8kW total PV input power. This inverter accepts a PV voltage of 500VDC maximum, with a 120VDC to 425VDC MPPT range and 18A input current per tracker in this solar power inverter configuration.

This design improves energy generation when solar panels have different:

• Roof orientations
• Tilt angles
• Shading conditions

Compared with single MPPT systems, dual MPPT architecture provides more PV system design options.

PV Input Comparison

Homeowners harvest more daily energy, increasing solar power inverter payback and securing backup power.

IP65 Outdoor Enclosure & Thermal Engineering

The inverter has an IP65 ingress protection shell. It operates from -40°C to +60°C. A fan cooling system adjusts air circulation based on internal thermal demand.

This IP65 rating permits outdoor installation of this solar power inverter. It protects solar power inverter power electronics from dust, rain, and humidity without secondary protective cabinets.

The design saves indoor space, keeps operational noise below 55dB, and removes additional enclosure installation costs for the inverter.

Capabilities Regarding Grid Feed-In

When solar power generation exceeds the load demand and battery charging capacity, the excess electricity can flow back to the grid.

If local power regulations or utility agreements prohibit exporting power to the grid, the inverter supports external anti-backflow control.

This feature allows you to limit or completely block power feedback into the grid depending on your site configuration.

48V Battery Compatibility for Flexible Energy Storage

The HC1040EH48L supports multiple battery technologies.

Compatible batteries include:

• Lithium-ion batteries
• Lead-acid batteries
• Gel batteries

The system operates with:

• Nominal battery voltage: 48VDC
• Battery voltage range: 40-60VDC
• Maximum charge/discharge current: 100A

This makes it suitable for:

• Residential solar storage
• Backup energy systems
• Remote power applications

Pure Sine Wave Output for Sensitive Home Appliances

The HC1040EH48L solar power inverter delivers stable AC output with:

• Rated voltage: 220V/230V/240V
• Pure sine wave waveform
• THDu <2% under linear load
• Power factor >0.99 at rated power

It safely powers household equipment including:

• Refrigerators
• Air conditioners
• Computers
• Communication devices
• Lighting systems

The hybrid solar inverter supports adjustable power factor operation from: 0.8 leading to 0.8 lagging

This improves compatibility with different electrical loads.

High Capacity Scaling

By paralleling up to 15 units, the system can scale from a single unit up to a maximum total output capacity of 60kW.

Inverter models designated with a “P” suffix  are equipped with parallel communication hardware. You can connect up to 15 units in parallel to scale total output power and battery capacity for larger residential or commercial installations. (Pm – Master; P – Slave).

Parallel-enabled units synchronize AC output frequency, voltage phase, and real-time load distribution via dedicated communication lines (RS485/CAN).

All connected units coordinate PV input power, charge/discharge cycles, and grid feed-in/backup modes seamlessly across the shared AC bus.

Fast Backup Switching and Generator Integration

For areas with unstable grid supply, the HC1040EH48L provides reliable backup performance.

Key functions include:

• ≤10ms transfer time
• Generator input support
• Grid and battery automatic switching

This allows continuous power supply for essential household loads.

Typical applications include:

• Rural homes
• Island energy systems
• Emergency backup power
• Off-grid solar solutions

Selling First Mode (Grid Export Priority)

Daytime: Solar power generation prioritizes powering local loads first. Any excess PV power generated beyond load demand is exported (sold) back to the utility grid.

Nighttime / Low Solar: When solar generation is unavailable, the system discharges the battery to supply connected loads. If battery energy is insufficient, the grid provides backup power

Integrated Protections & International Compliance
