As solar adoption expands across residential and commercial segments, the focus is increasingly shifting beyond electricity generation towards energy storage, intelligent power management and reliable backup solutions. Hybrid inverters are becoming an important part of this transition, enabling solar installations to integrate battery storage and manage electricity supply across different operating conditions.
Addressing these evolving requirements, Polycab India offers a portfolio of single-phase and three-phase hybrid inverters designed for applications ranging from residential rooftop installations to commercial solar projects.
Single-Phase Hybrid Inverters: Designed for Residential Rooftop Solar
Polycab’s single-phase hybrid inverter range comprises 3 kW, 3.6 kW, 5 kW and 6 kW models, developed for residential rooftop solar systems, including applications under the PM Surya Ghar initiative. Available with single or dual Maximum Power Point Tracking (MPPT) configurations, the inverters provide flexibility in solar array design and energy generation management.
The range integrates with 48V lithium-ion and lead-acid batteries, supporting solar energy storage and backup requirements. A multifunctional 3-in-1 port accommodates generator, smart load and on-grid inverter connections, providing flexibility for different energy management needs.
The models also support on-grid and off-grid parallel operation of up to six units, allowing system capacity to be expanded according to energy requirements. With maximum efficiency of 97.6% and MPPT efficiency of 99.9%, the series is designed to support efficient energy conversion for residential solar applications.
Three-Phase Hybrid Inverters: Supporting Residential and Commercial Projects
For larger installations, Polycab’s three-phase hybrid inverter series offers capacities of 5 kW, 8 kW, 10 kW, 15 kW and 20 kW. Designed for residential and commercial applications, these models incorporate two, three or four MPPTs, depending on capacity, providing flexibility for different solar installation configurations.
The series supports 48V lithium iron phosphate (LFP) and lead-acid battery systems. The 15 kW and 20 kW variants feature dual independent battery inputs, enabling greater flexibility for higher-capacity energy storage integration.
An additional feature is unbalanced output capability of up to 150%, supporting applications where electricity demand varies across different phases. The three-phase range offers maximum efficiencies between 97.8% and 97.9%, along with MPPT efficiency of 99.9%.
Advanced Features Across Both Inverter Ranges
Both single-phase and three-phase hybrid inverters support up to 200% PV input oversizing, subject to applicable conditions, and accommodate a maximum input current of 20A per MPPT. These specifications provide flexibility in solar array sizing and compatibility with high-current photovoltaic modules.
The inverters also offer seamless switching to backup power in less than 4 milliseconds. Combined with smart load control, this capability helps maintain electricity supply to connected backup loads during grid interruptions.
Safety and reliability are supported through IP66-rated enclosures, integrated electrical protection systems and optional AI-driven Arc Fault Circuit Interruption (AFCI) functionality. Communication capabilities include Wi-Fi, LAN, Bluetooth and RS485, supporting system monitoring and operational management.
By combining solar conversion, battery compatibility, intelligent monitoring and backup functionality, Polycab’s hybrid inverter portfolio provides a range of options for different installation capacities. The product range reflects the increasing importance of integrated solar-plus-storage solutions in residential and commercial energy systems.
