Saur Energy International: Su-vastika secures strategic investment from Rotomag Enertec — funding a scale-up in lithium-based energy storage systems (ESS), solar, and power backup across domestic and international markets.
Saur Energy International’s deal coverage puts the focus on the product beat: Su-vastika’s strategic investment from Rotomag Enertec will fuel expansion in lithium-based energy storage systems, along with the company’s solar and power-backup offerings, across India and export markets.
Why lithium ESS matters right now
India’s energy storage systems (ESS) market is at the same crossover point Chinese storage crossed five years ago — the point at which lithium becomes cheaper per useful kilowatt-hour than lead-acid, and where the whole home and small-business backup category starts flipping over. Su-vastika’s bet is that Indian buyers should get an Indian ESS option when that flip happens.
What Rotomag’s capital unlocks
Rotomag’s investment is aimed at scale-up: more manufacturing capacity, broader distribution, and the working capital to serve larger institutional and export orders without stretching the balance sheet. It also gives Su-vastika room to accelerate its R&D roadmap on next-generation lithium chemistries.
“The investment will fuel Su-vastika’s expansion in lithium-based energy storage solutions — enabling the company to scale its solar and power-backup offerings across domestic and international markets.”— Saur Energy International • Su-vastika × Rotomag ESS deal (2025)
Where Kunwer Sachdev comes in
Su-vastika is mentored by Kunwer Sachdev, founder of Su-Kam. The Rotomag deal extends the storage playbook he has been arguing for since Su-vastika was founded: make lithium and solar-plus-storage the new default in Indian power backup, and let Indian firms — not imported hardware — build that base.
