Solterra Technologies Partners with Sinpro Electronics: EV Motors, Controllers and DC-DC Converters Head to India

Ghaziabad-based EV charging and power electronics startup Solterra Technologies has signed an exclusive distribution partnership with Taiwan's Sinpro Electronics to bring Sinpro's EV motors, motor controllers and DC-DC converters to Indian electric vehicle makers and mobility companies. The deal, announced in mid-September 2026, arrives alongside a new Solterra R&D office in Bengaluru built for product development, testing and technology adaptation. It's a distribution and engineering-support tie-up rather than a local manufacturing one, which places it at a specific point on India's EV component localisation spectrum, explained below.

What Solterra Technologies and Sinpro Electronics announced

Under the agreement, Solterra Technologies will distribute Sinpro's EV motors, motor controllers and DC-DC converters across the Indian market, offering them to electric vehicle manufacturers and mobility companies. The two companies will also work together on integrating and applying these components for electric mobility use cases in India.

Neither company has disclosed the financial terms of the deal, a specific product line-up for the Indian market, or a timeline for when the first Sinpro-sourced components will ship to Indian customers.

Sagar Bose, Chief Technology Officer at Solterra Technologies, framed the tie-up around engineering capability: "India's EV industry is entering a phase where technology, performance and engineering capability will play an increasingly important role in shaping the next generation of mobility. Our exclusive partnership with Sinpro Electronics allows us to expand our technology portfolio with proven EV powertrain solutions, including motors, motor controllers and DC-DC converters."

Bill Su, EV Powertrain Leader at Sinpro Electronics, pointed to India's scale: "India represents one of the most important and dynamic markets for electric mobility, with significant opportunities for technology innovation and industry growth. Through our exclusive partnership with Solterra Technologies, we are bringing Sinpro's EV powertrain technologies closer to Indian OEMs and mobility companies."

About Solterra Technologies

Solterra Technologies Pvt. Ltd. is a Ghaziabad-based EV charging and power electronics startup founded in 2022. Its existing line-up includes IP67-rated EV chargers for two-, three- and four-wheelers, power modules, EV controllers and communication devices, alongside power electronics solutions, deep-tech consultancy and design services for automotive and industrial customers.

The Sinpro tie-up extends this range into powertrain-side components (motors, motor controllers and DC-DC converters) that Solterra didn't previously offer.

About Sinpro Electronics

Sinpro Electronics Co. Ltd., founded in 1995 and headquartered in Taiwan, is a power electronics manufacturer and designer. Its broader catalogue spans AC-DC switching power supplies, LED drivers and DC-DC converters for industrial applications, alongside a dedicated EV product line of IPM motors, motor controllers and DC chargers for electric bicycles, scooters and golf carts.

Sinpro's EV motors and motor controllers have previously won recognition at Taiwan's Taiwan Excellence Awards, where the company's products are listed with quality certifications including ISO 9001, ISO 14001 and IATF 16949.

The new Bengaluru R&D office

Solterra Technologies is also opening an R&D facility in Bengaluru, reported to be targeted for inauguration around September 18, 2026. We haven't been able to independently confirm that the inauguration event itself has taken place; this section will be updated once that's verified.

The facility is expected to support:

• Product development and engineering for India-specific requirements
• Testing and technology adaptation of Sinpro's components for Indian operating conditions
• A base for technical collaboration with OEMs and other technology partners

This is a genuine local investment, separate from the distribution deal itself: it puts Solterra's own engineers in a position to integrate and validate Sinpro's imported hardware for Indian vehicles, rather than simply reselling components as-is.

Where this fits in India's EV component supply chain

India's EV industry still leans heavily on imports for exactly the kind of components covered by this deal. A June 2026 report from the Institute for Energy Economics and Financial Analysis (IEEFA) and JMK Research found that India could reach 90–100% localisation across several non-battery EV component categories by 2030 if planned manufacturing capacity for powertrain systems, power electronics and charging equipment gets commissioned on schedule.

The same research flagged how import-dependent motors and controllers specifically remain today: traction motors rely entirely on imported rare-earth magnets, and motor controller units and vehicle control units depend entirely on imported semiconductors. Together, these parts account for a meaningful share of a vehicle's total value, with power electronics and thermal systems adding further to that share.

Government incentives are pushing the other way. Around 60% of recent EV non-battery component manufacturing announcements have come from companies approved under India's Production-Linked Incentive scheme for Automobile and Auto Components (PLI Auto), though less than 10% of the scheme's ₹25,938 crore (~$2.98 billion) outlay had been disbursed by early 2026, according to the same report.

A distribution deal like Solterra-Sinpro doesn't move the localisation needle on its own since the components themselves stay imported. What it does is put an Indian engineering team between the foreign manufacturer and Indian OEMs, which is often how deeper manufacturing commitments start.

How it compares with other recent EV powertrain partnerships in India

Several similar tie-ups between Indian companies and global power-electronics or motor specialists have landed in the past year, but they don't all mean the same thing on the ground:

The Sterling Gtake-Landworld agreement is projected to generate around ₹450 crore in business by FY2030 in a component segment the companies peg at roughly ₹3,000 crore, and it involves actual local production rather than distribution.

What this means for Indian EV makers and mobility companies

For OEMs and mobility fleet operators evaluating powertrain suppliers, this deal adds one more sourcing option for motors, motor controllers and DC-DC converters, backed by a local point of contact for integration support rather than dealing directly with a Taiwanese supplier.

What it doesn't change, at least not yet:

• Pricing and lead times for Sinpro components in India, since neither company has published a price list or delivery timeline
• Import duties, since these components will still cross the border as finished goods rather than being made domestically
• The broader import-dependency picture for Indian EVs, since one distribution deal doesn't add new domestic manufacturing capacity

OEMs already sourcing from Sinpro through other channels, or evaluating alternatives like Sterling Gtake's locally manufactured DC-DC converters, will want to weigh Solterra's engineering and integration support against the cost and lead-time trade-offs of an imported component versus a domestically made one.

Evfy's Take

Most coverage of this deal has folded it into the general "global player enters India's EV market" narrative. We think the more useful read is that it sits one rung below the manufacturing commitments Sterling Gtake and Spark Minda have made in the same component categories over the past year.

A technology licence or a joint venture obligates a foreign partner to transfer know-how and stand up production lines on Indian soil. A distribution agreement, even an exclusive one, obligates the foreign partner to almost nothing beyond shipping product. The Bengaluru R&D office is the part of this announcement worth watching: if it eventually leads to local assembly or manufacturing, this deal becomes a genuine localisation story. If it stays limited to integration support and testing, it's best read as Sinpro testing Indian OEM demand through a local partner before committing to anything bigger, a fairly standard market-entry pattern for component makers new to India.
