Wattox

What Wattox does

Wattox (legal entity Inavitas) is a power electronics manufacturer founded in 2001 that designs and produces PV string inverters, central and string power conversion systems (PCS) for battery energy storage, and an integrated PPC/APM monitoring and control stack. Its product portfolio spans 150–506 kW string PV inverters (all 1500V DC, multi-MPPT, IP66, 99%+ efficiency), 1,250–3,500 kW central PCS with liquid cooling and grid-forming/grid-following capability, and a 213 kW string PCS (LUNA2000-213KTL-H0) that is compatible with Huawei FusionSolar. The company manufactures at two Turkish facilities — a 4,850 m² site in Ankara's Sincan Organized Industrial Zone and a second plant in Niğde — with stated annual capacity of 10+ GW, while R&D and corporate engineering are headquartered in Ankara. Wattox is registered with headquarters in Düsseldorf, Germany, and operates a regional office in Voluntari, Romania, for Eastern European sales.

The company serves utilities, independent power producers (IPPs), commercial and industrial customers, and project developers/EPCs, with a primary focus on utility-scale solar PV and grid-scale battery energy storage projects. Revenue is generated predominantly through one-time hardware sales of inverters and PCS, supplemented by professional services, spare parts, warranty support, and what appears to be software licensing for the PPC/APM platform. Go-to-market is enterprise field sales with direct technical consultation and project-by-project configuration, supported by digital channels (corporate website, LinkedIn, YouTube, Facebook, Instagram). Differentiators emphasized by the company include 75+ supported international grid codes, CE/IEC/UL certifications, grid-forming capability for BESS with sub-30 ms response, AI-assisted predictive maintenance via APM, and "Made in Europe" manufacturing with a Turkish cost base. Disclosed customers (Aksa Enerji, Egesa, Pekintaş, Ecogreen, Masfen) are concentrated in the Turkish energy sector, and the company has delivered 5,000+ units across Europe and the Middle East.

Core offering

Wattox designs and manufactures advanced power electronics for renewable energy, producing high-efficiency PV string inverters (150kW, 330kW, 506kW), Central Power Conversion Systems (1250kW-3500kW) for battery energy storage, and a String PCS (213kW), complemented by integrated Monitoring & Control platforms (PPC and APM) for utility-scale solar and storage projects.

Product overview

Wattox offers an integrated portfolio of advanced energy conversion systems comprising PV string inverters, Central and String Power Conversion Systems (PCS), and Monitoring & Control solutions (PPC and APM). The PV inverter lineup includes three models: 150 KTL-H1 (150 kW), 330 KTL-H1 (330 kW), and 506 KTL-H1 (506 kW), all built on 1500 V DC architecture with multi-MPPT design for utility-scale solar applications. The Central PCS family spans four power ratings—MPCS-1250-S (1250 kW), MPCS-1725-S (1725 kW), MPCS-2500-D (2500 kW), and MPCS-3500-D (3500 kW)—for battery energy storage and hybrid systems, featuring liquid cooling and grid-forming/grid-following capabilities. The String PCS (LUNA2000-213KTL-H0, 213 kW) provides modular energy storage integration. The Monitoring & Control layer combines PPC for plant-level grid compliance control and APM for real-time asset performance management and predictive maintenance.

Direct peers

• Sungrow Power Supply: One of the world's largest manufacturers of PV string and central inverters plus utility-scale PCS for BESS, with broad global reach. Most directly comparable to Wattox on product scope (string inverters + central PCS) and target customers (utility-scale and C&I solar+storage developers).
• Sineng Electric: Chinese manufacturer of PV string and central inverters plus PCS for utility-scale BESS. Competes with Wattox in the same medium-to-large power classes (string inverters and 1–3+ MW central PCS) and increasingly in Europe and MENA.
• SMA Solar Technology: German-headquartered manufacturer of PV inverters (string and central) and battery/storage solutions for utility, C&I and residential markets. Closest geographic and product peer to Wattox, sharing a German commercial base and similar focus on grid compliance and grid-forming capability.
• Huawei Digital Power: Global supplier of utility-scale PV string inverters and Smart String ESS (PCS) solutions under the FusionSolar brand. Directly competes with Wattox's PV inverter and String PCS lines, and is also a strategic partner via FusionSolar ecosystem compatibility.
• Hopewind Electric: Chinese supplier of wind and solar power conversion equipment, including utility-scale PV inverters and BESS PCS. Comparable to Wattox on utility-scale PCS power range and increasingly relevant as a competitor in EMEA tenders.
• FIMER: Italian-headquartered manufacturer of PV string and central inverters plus energy storage solutions serving utility, C&I and residential segments. Similar product portfolio to Wattox with a European manufacturing base and comparable regulatory-compliance focus.
• KACO new energy: German manufacturer of string and central PV inverters (now part of Siemens AG / KACO group) with a focus on utility-scale and C&I solar. Directly comparable to Wattox's string PV inverter line on technology class and target customers.
• Power Electronics (Spain): Spanish manufacturer of solar inverters, BESS PCS and motor drives, with a strong utility-scale BESS offering. Comparable to Wattox on PCS product range, grid-forming capability, and focus on utility-scale and C&I solar+storage projects outside the dominant Chinese suppliers.

Broad incumbents

• Schneider Electric: Global energy management and automation major with a power-conversion portfolio spanning solar inverters, BESS PCS, microgrids and grid services software. Comparable to Wattox on PCS and grid-compliance software (PPC/APM equivalent functionality) but operates at significantly larger scale across many adjacencies.
• ABB (Electrification / Motion): Global industrial conglomerate offering power conversion, switchgear, transformers and grid-tied energy storage solutions through its Electrification and Motion businesses. Overlaps with Wattox in PCS, grid-forming capability, and grid-compliance hardware, but as part of a much broader portfolio.
