The IP65 hybrid solar inverter supports:

• 5kW rated AC output power
• 10kW recommended maximum PV input
• 48V lead-acid, gel, and lithium battery compatibility
• Up to 15 units parallel connection
• IP65 outdoor protection design

It is optimized for customers seeking a reliable 5kW hybrid solar inverter with battery backup for energy independence and reduced electricity costs.

Why Hybrid Energy Systems are Needed

Increasing Demand for Reliable Residential Power

Modern households face several energy challenges:

• Rising electricity prices
• Grid instability
• Frequent power interruptions
• Higher demand for renewable energy integration

Traditional grid-connected solar systems cannot provide backup power when the grid fails.

A standard solar inverter shuts down during outages due to anti-islanding requirements.

A hybrid inverter solves this limitation by combining:

• Solar generation
• Battery storage
• Grid connection
• Backup output

This allows households to maintain critical loads even during grid failures.

HC1050EH48L Smart Energy Management Platform

The HC1050EH48L provides a complete solar battery backup system inverter solution.

The system automatically determines the optimal energy source:

This intelligent switching improves renewable energy utilization and enhances household energy security.

Technical Specifications

Key Features

Dual MPPT Input, 10kW PV Capacity

The IP65 hybrid inverter accepts up to 10kW PV input (5kW + 5kW) across two independent MPPT trackers, with an MPPT voltage range of 120–425VDC.

Oversizing the PV array relative to the 5kW inverter rating captures more usable energy during low-light, dawn, and dusk hours.

Homeowners get more daily kWh harvested per installed inverter, reducing payback period without buying a larger inverter.

Wide Battery Compatibility at 48VDC

Supports lead-acid, gel, and lithium-ion batteries at 48VDC nominal voltage (40–60VDC range), with max charge/discharge current of 110A.

Installers are not locked into one battery chemistry or one brand, simplifying system design and future battery upgrades.

This flexibility makes the HC1050EH48L a practical 48v hybrid inverter for battery backup projects ranging from retrofit lead-acid systems to new lithium installations.

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.

Grid and Generator Compatibility

Flexible Parallel Expansion Capability

Expandable Energy Capacity

The HC1050EH48L supports parallel operation of up to:

15 units

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).

This enables flexible system expansion.

Example:

Application Advantages

Parallel capability allows users to:

• Expand solar capacity gradually
• Increase backup power capability
• Support larger residential or small commercial projects

This reduces initial investment pressure while keeping future scalability.

IP65 Protection Design for Outdoor

The HC1050EH48L adopts an IP65 protection enclosure, allowing reliable operation in demanding environments.

The IP65 rating means:

• Protected against dust ingress
• Protected against low-pressure water jets
• Suitable for indoor and outdoor installation

This makes it an ideal IP65 hybrid inverter for residential solar systems where equipment may be installed in garages, utility rooms, exterior walls, or protected outdoor areas.
