The Grid-Interactive Hybrid PV System with EV Charger combines solar power generation, battery energy storage, grid interaction, and electric vehicle charging into one seamless energy solution.
Why Choose a Grid-Interactive Hybrid PV System with EV Charger?
Maximize Solar Self-Consumption
Traditional grid-tied systems often export surplus power to the grid at low feed-in tariffs. This hybrid system directs available solar energy to:
Facility electrical loads
On-site battery storage systems
Connected electric vehicles
Grid export (where economically advantageous)
Lower Electric Vehicle Charging Costs
The integrated EV charging functionality allows vehicles to charge using locally generated solar energy. The system automatically adjusts charging rates based on real-time solar yield, battery State of Charge (SoC), building load demand, and dynamic utility tariffs-minimizing reliance on peak-rate grid power.
Ensure Continuous Backup Power
Unlike standard grid-tied PV systems that shut down during grid outages, this solution provides instantaneous backup power for essential loads. Stored energy powers critical systems-such as lighting, IT infrastructure, security, and refrigeration-without manual switching via an automatic transfer process.
Modular & Future-Ready Scalability
Energy demands naturally grow as facility loads expand or fleet electrification increases. The modular system design enables independent scaling of:
Battery storage capacity (kWh)
Solar PV capacity (kW)
EV charging power and outputs (kW)
Key Product Features
Integrated Solar, Storage & Charging Architecture
The system coordinates all energy inputs and outputs through a unified control matrix:
Configurable Smart EV Charging Modes
• Solar Priority Mode: Uses available solar generation to deliver 100% green EV charging.
• Solar & Battery Mode: Combines solar power and battery discharge for fast charging off the grid.
• Grid-Assisted Mode: Supplements solar and battery power with grid electricity when rapid charging is required.
• Scheduled / Peak-Shaving Mode: Operates during off-peak tariff hours to minimize charging expenditure.
Intelligent Energy Management System (EMS)
The integrated EMS continuously monitors solar yield, battery State of Charge (SoC) & State of Health (SoH), building load dynamics, and grid stability to automatically select the most cost-effective power source in real time.
Remote Platform & Fleet Management
Users and system managers can monitor and operate the system remotely via web and mobile applications:
Real-time power flow graphics and historical energy analytics
Battery lifecycle tracking and operational diagnostics
EV charging station status and billing/monetization management
Remote Over-The-Air (OTA) firmware updates
