Fujiyama Power Systems Set To Launch Microinverters Soon: Pawan Garg

Our core strength lies in rooftop solar solutions, but our journey began in power electronics. We started with inverters and gradually integrated solar functionality into them around 2008, launching solar inverters at a time when the rooftop market was still nascent. As our dealer network expanded, there was growing demand for complete solar solutions, which led us to add solar panels and batteries to our portfolio. Post-COVID, we moved into manufacturing solar panels and batteries as well. Today, we have a manufacturing capacity of 1.5 GW each in solar inverters, solar panels and solar batteries, making us fully integrated across the key components of rooftop systems.

Are your modules manufactured primarily for captive use or for third-party sales?

At present, our module production is largely for captive use within our own rooftop ecosystem. In the rooftop segment, the inverter is the technological backbone of the system, as it determines features and performance. Panels and batteries are selected depending on the customer’s budget and load requirement. Since we provide complete solutions, our manufacturing aligns closely with our system integration strategy rather than merchant module sales.

How extensive is your product range across panels, batteries and inverters?

We offer a broad portfolio with over 500 SKUs across categories. In solar panels, we manufacture products ranging from 40 watts up to 600 watts, covering multiple technologies and configurations. In batteries, we provide lead-acid variants from 40Ah to 300Ah, along with lithium-ion batteries ranging from 1.2 kWh to 48 kWh. In the inverter segment, we cover off-grid, hybrid and on-grid systems, starting from 100 VA and going up to 120 kVA in hybrid configurations. This wide range allows us to tailor solutions based on application type, geography and affordability.

Are you also engaged in EPC or installation activities?

We are primarily a manufacturing-driven company. However, we operate through a strong channel ecosystem comprising over 8,000 channel partners, 850 distributors, and more than 1,100 exclusive franchise outlets. Additionally, we have more than 800 service engineers deployed in the field. While installations are executed through our partners, we provide end-to-end system design and technical support. Our focus is on delivering reliable solutions backed by strong after-sales service at the grassroots level.

How has the adoption of hybrid inverters evolved in India?

Hybrid adoption has accelerated significantly, especially after the PM Surya Ghar initiative and the extension of subsidies to hybrid systems up to 3 kW. Earlier, many customers opted for off-grid systems due to affordability and awareness constraints. Now, hybrid systems are gaining traction because they combine grid interaction with backup functionality. India’s rooftop potential is estimated to be extremely large, yet penetration remains relatively low. Government initiatives addressing affordability, awareness and financing are acting as catalysts for growth.

How are your hybrid inverters packaged — integrated systems or separate components?

We offer some models with inbuilt lithium-ion batteries, but most systems are configured with separate batteries. The combination depends on customer requirements. When we initially promoted rooftop solar, we introduced a 50-50 model where battery capacity was reduced and compensated with solar panels. This maintained overall system cost while improving economics and reducing long-term battery replacement expenses. Education and awareness played a major role in scaling rooftop adoption, particularly in tier-2, tier-3 cities and rural markets.

You mentioned plans to launch microinverters. What can we expect?

Our microinverter solutions are currently in the trial phase, and we expect to launch them commercially within the next six months. We anticipate strong demand in the 700-watt category, aligned with single-panel applications. Microinverters offer benefits such as improved performance under shading conditions and per-panel optimisation. As module wattages increase in the future, microinverter capacities will also evolve accordingly.

What are your expansion plans going forward?

Our strategy has consistently focused on backward and forward integration. We began with inverters, expanded into solar inverters, then added panels and batteries, and recently commissioned 1 GW of solar cell manufacturing capacity. We are deeply backward integrated in transformers, sheet metal, PCB design, wire harnessing, BMS and battery manufacturing. Energy storage represents a significant growth opportunity, particularly in residential and C&I segments. With strong technical capabilities and an established service network, we see continued expansion in integrated solar and storage solutions.
