What Enertronica Santerno does

Enertronica Santerno S.p.A. is an Italian vertically integrated manufacturer of power electronics, founded in 1970 and headquartered in Castel Guelfo di Bologna, Italy. The company designs and produces inverters and motor drives for industrial automation, photovoltaic power generation, and battery energy storage systems (BESS). Core products include the Sinus M, Sinus H, Sinus Penta, and Sinus MV-X inverter series for three-phase asynchronous and synchronous motors; the ASAB and Asamv-X soft starters; the SUNWAY TG 2000 BESS bidirectional multi-level NPC inverter for utility-scale storage with grid-forming, black-start, and virtual-inertia functions; and a patented DC/DC multilevel converter using Silicon Carbide technology currently in testing. The company also operates a Monitoring & Cloud platform for remote asset management.

Enertronica Santerno serves three primary customer segments: industrial automation operators across water, food and beverage, cement, chemical, HVAC, marine, mining, oil and gas, plastics, metals, and crane systems; photovoltaic developers and operators for utility-scale and C&I installations; and energy storage / smart grid operators including transmission system operators. The company holds the position of first Italian player in photovoltaic inverters with 12+ GW of globally installed capacity and maintains manufacturing in Italy and South Africa (Santerno South Africa, with 40%+ local content), plus sales and service operations in the United States (Enertronica Inc.). End markets span Italy, Greece, Romania, Spain, South Africa, the United States, Brazil, Panama, Chile, and additional countries in Africa, Asia, and Latin America.

The business model combines one-time hardware sales (inverters and power stations for PV, storage, and industrial automation) with multi-year recurring revenue from O&M services, revamping, spare parts supply, and warranty extensions. Major disclosed contracts include a €40 million binding agreement for 1.5 GW of storage inverters (December 2022), €2.5 million for 16 MW of storage inverters for an Italian TSO, a €6 million multi-country spare parts and maintenance framework, and a €0.9 million supply for 20 MW of photovoltaic power stations to STE Energy S.r.l. Pricing is enterprise-quoted, B2B, and not publicly disclosed. The company has been listed on Euronext Growth Milan since 2014 under ticker bit:ENT, with share capital of €784,988.40 and 7,849,884 shares outstanding.
