Key Features

Grid-Connected Operation with Self-Consumption Optimization

In grid-connected mode, the inverter directs solar generation to household loads. Surplus PV energy charges the 48V battery system. Remaining generation feeds to the grid. This configuration reduces utility grid draw during solar hours (e.g., 9 AM to 4 PM) and lowers electricity costs through time-of-use (TOU) tariff management (e.g., charging battery at off-peak rates, discharging during peak rates).

Battery Energy Management

The integrated battery management system (BMS) controls charge/discharge cycles based on:

Real-time household load demand
Available solar generation
Grid electricity pricing (TOU schedules)
State of charge (SOC) thresholds

This management extends battery lifespan (e.g., reduces cycle count by 15-20% compared to fixed schedule) and maximizes the economic value of stored energy (e.g., saves $0.20 per kWh shifted).

Up to 21kW Recommended PV Input

The HC1105EH48L solar hybrid inverter 10.5kW supports a recommended maximum PV input power of 21kW.

The PV array can be sized at 2:1 relative to the inverter’s 10.5kW AC output rating.

This enables solar energy harvesting during periods when irradiance is below 1000 W/m² or household demand varies.

For example, a 21kW PV array generates useful power during:

Morning hours (e.g., 8-9 AM: 5-8 kW)
Late afternoon (e.g., 4-5 PM: 6-9 kW)
Cloudy conditions (e.g., 40% irradiance: 8 kW)
Winter months (e.g., December: 10-12 kW peak)
Low-load periods

The inverter can therefore be designed around high-capacity residential solar storage (e.g., 20 kWh battery) rather than only around the instantaneous AC load.

IP65 Protection for Residential Energy Systems

The HC1105EH48L uses an IP65-rated enclosure.

IP65 protection provides protection against dust ingress (dust-tight) and water jets from any direction (12.5 mm nozzle, 100 L/min at 100 kPa).

This makes the inverter suitable for installation in indoor, utility-room, garage, covered outdoor, and other environments where IP65 protection is required.

However, IP65 should not be interpreted as unrestricted exposure to every weather condition.

Installation should still consider:

Direct sunlight
Rain exposure
Ambient temperature
Ventilation
Condensation
Salt mist
Dust concentration
Required clearances

The IP65 solar hybrid inverter should be installed according to the manufacturer’s installation instructions and applicable local electrical codes.

Off-Grid & Backup Power Capability

When grid power is unavailable, the inverter switches to battery-powered mode within 10 ms, supporting essential loads. The 48V architecture delivers up to 220 A current, powering multiple essential circuits simultaneously (refrigeration: 1.5 kW, water pump: 1.2 kW, lighting: 0.5 kW, communication devices: 0.2 kW = total 3.4 kW continuous).

Parallel Expansion Capability for Larger Energy Systems

The HC1105EH48L supports parallel connection.

Maximum parallel quantity: Up to 15 units

Multiple inverter units can operate together to increase system capacity.

A single unit provides:

10.5kW output power

A 15-unit parallel system can theoretically reach:

157.5kW class power capacity

This scalability makes the inverter suitable for:

Large residential buildings
Small commercial facilities
Farm energy systems
Microgrid projects

Generator Compatible Hybrid Power Solution

The HC1105EH48L supports generator integration.

Compatible with:

Diesel generators
Gas generators
Backup generators

Generator input provides additional energy security when:

Solar resources are limited
Battery capacity is insufficient
Grid connection is unstable

The inverter manages multiple power sources automatically.

Users in remote or unstable grid areas can build a more reliable energy system.

Typical markets include:

Rural areas
Islands
Developing regions
Off-grid communities

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.

Recommended Application

Large Detached Homes

High-consumption homes can use the HC1105EH48L where a conventional 5–6kW inverter may be undersized.

Solar + Battery Backup

The inverter can form the central power-conversion component of a residential storage system using a compatible 48V battery.

The objective is to shift solar energy from daytime generation toward evening and backup applications.

High-PV Rooftop Systems

The 21kW recommended PV capacity makes the HC1105EH48L suitable for homes with substantial roof area.

It can be particularly relevant where the customer wants:

More annual solar generation
Greater morning/afternoon production
Higher self-consumption
More battery charging energy

FAQ

What makes a 48V hybrid energy storage system safer for home installation compared to high-voltage setups?

A 48V low-voltage architecture operates below the extra-low voltage (ELV) safety threshold of 60V DC. This significantly reduces DC arc flash hazards, simplifies battery wiring safety protocols, and minimizes electrical shock risks during installation and maintenance.

How does this residential battery inverter manage peak power demands during grid outages?

The system provides a 10,500W continuous AC output and can handle peak surge loads up to 15,750VA for 10 seconds. This surge capability allows high-draw inductive equipment, such as HVAC compressors or water pumps, to start reliably without tripping the inverter off-grid protection.

How many MPPTs does this 10.5kW residential solar hybrid inverter have?

It provides 2 MPPT trackers, supporting 2 + 2 PV strings. The maximum PV input current is 36A + 36A, while the maximum PV short-circuit current is 40A + 40A.

Can this off-grid solar inverter operate effectively without a grid connection?

Yes, the unit includes full off-grid capabilities. It can start directly from PV array power or battery storage (black start), regulate local voltage and frequency, and interface with backup generators via built-in dry contacts when renewable input is insufficient.

Does the multi-mode solar power converter support smart grid feed-in management?

Yes, integrated control modes allow full customization of power flows. Users can configure peak shaving, zero-export feed-in limits, self-consumption priority, or time-of-use (TOU) battery charging schedules through the monitoring app or Modbus interface.

How does the IP65 rating protect the unit in outdoor installations?

The IP65 enclosure provides complete protection against dust ingress and low-pressure water jets from any angle. Combined with a wide operating temperature range (-25°C to 60°C), it allows reliable outdoor mounting under direct sunlight or rain without compromising internal components.
