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.
Typical loads include multiple air-conditioning units, refrigeration, water heating, pumps, and kitchen equipment.
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

It can be particularly relevant where the customer wants:
- More annual solar generation
- Greater morning/afternoon production
- Higher self-consumption
- More battery charging energy
