Ampt product offering
Product offeringCore offering
Ampt designs and manufactures DC/DC String Optimizers (i12, i13.5, i20, i32, i50) for utility-scale PV plants that perform string-level maximum power point tracking and deliver power at a fixed high DC bus voltage. The portfolio also includes the Ampt Communication Unit (CU), a wireless data hub that pushes string-level telemetry to SCADA systems via Modbus/TCP in SunSpec format, and engineering and project support services for new builds, repowering, and DC-coupled solar-plus-storage projects.
Product overview
Ampt offers a unified portfolio of String Optimizer products complemented by the Communication Unit (CU). The String Optimizer product line includes five models (i50, i32, i20, i13.5, i12) ranging from 600V to 1500V systems and varying power capacities. All String Optimizers are DC/DC converters that perform maximum power point tracking (MPPT) on each PV string input and deliver full available power at a fixed output voltage. The Ampt CU collects telemetry data from the optimizers via wireless communication and provides Modbus/SunSpec integration with SCADA and monitoring systems. The products work together to lower PV system costs, improve performance, and enable DC-coupled storage applications.

Strategic signalPartnerships
Five partnerships are on record, tiered core and minor.
- Hiringa EnergycoreAmpt is collaborating with New Zealand-based Hiringa Energy to deploy string optimizer technology for a 27 MW solar + 30 MWh battery storage system at the Good Earth Green Hydrogen and Ammonia project in Australia. The AUD 35.8 million project is partially funded by the Australian government and aims to produce green hydrogen and ammonia for low-carbon cotton production using Ampt's DC-coupled battery-centric design.
- eks EnergycoreAmpt partnered with eks Energy to deliver an end-to-end power conversion solution supporting the largest PV+storage power plant in Latin America. The partnership combines Ampt's string optimizers with eks Energy's power conversion technology to demonstrate the advantages of fixed-voltage DC-coupled PV+storage architecture.
- SolBerry AGminorSolBerry AG partnered with Ampt to build an agrivoltaic DC microgrid for a Swiss raspberry farm. Ampt String Optimizers were integrated into the energy solution to enable reliable, cost-effective clean energy production for agricultural operations and neighboring consumers.
- MSP TechnologiesminorMSP Technologies expanded DC-coupled PV+storage deployments through collaboration with Ampt. Partnership based in Holme, England.
- HDPV AllianceminorAmpt co-founded the HDPV Alliance in 2012, a solar industry alliance of over forty companies from around the world. Ampt's VP Strategic Marketing Mark Kanjorski serves as founding Chair.

Ampt competitors and assessment
Company assessmentDirect peers
- SolarEdge: Pioneer in DC power optimizers paired with inverters for solar PV, with growing commercial and industrial presence. Closest functional analog to Ampt's string-level DC/DC conversion approach, though historically more focused on residential and now expanding into batteries and C&I storage.
- Enphase Energy: Leading module-level power electronics company using microinverters rather than string optimizers. Competes for the same module-level optimization value proposition Ampt offers and is expanding into batteries, making it a strategic adjacent competitor in distributed PV+storage.
- APsystems: Microinverter and module-level electronics manufacturer for residential and commercial solar. Comparable as a peer in module-level power electronics addressing mismatch, shading and monitoring—adjacent architecture to Ampt's string-level DC optimizers.
- Tigo Energy: Module-level power electronics (MLPE) company offering DC optimizers for solar PV. Comparable to Ampt as a direct MLPE/optimizer competitor, though Tigo's commercial focus is more skewed to residential and small commercial segments while Ampt targets utility-scale.
Emerging players
- Power Electronics: Spanish manufacturer of solar inverters and battery energy storage systems, already a named Ampt partner for the largest Latin America PV+storage plant. Closely comparable in DC-coupled PV+storage architecture and a credible OEM partner/competitor in LATAM, Europe and Australia.
Broad incumbents
- Ginlong Solis: Global string inverter manufacturer with strong utility-scale and C&I presence. Competes with Ampt as an inverter OEM whose evolving string inverter capabilities increasingly overlap with Ampt's BOS-cost and DC:AC optimization value proposition.
- Huawei Digital Power: Smart PV inverter and storage solutions provider with global utility-scale footprint. Indirect incumbent competitor—its smart string inverters and integrated optimizers compete for the same BOS cost-reduction and MPPT value Ampt provides at utility scale.
- SMA Solar Technology: German-headquartered global inverter manufacturer with a strong utility-scale and storage presence. A broad incumbent whose string and central inverter roadmap determines whether utility-scale developers need Ampt's optimizers at all.
- Sungrow: One of the world's largest solar inverter manufacturers with broad utility-scale and storage portfolios. Competes with Ampt indirectly because its central/string inverters can absorb functionality similar to Ampt Mode and could compress the standalone optimizer opportunity.
Regional players
- Fronius International: Austrian inverter and solar electronics manufacturer with strong presence in Europe and Australia. Comparable as a utility-scale and C&I inverter competitor, particularly relevant to Ampt in the European and Australian markets where both firms actively compete.
