Products that Deliver Unmatched Value

Ampt optimizers are DC/DC converters that enable PV systems to deliver more value than traditional system designs without Ampt.

String Optimizers

Ampt String Optimizers are used to lower the cost and improve performance of new PV systems, upgrade existing systems to produce more energy, enable low-cost DC-coupled solar+storage systems, and provide string-level data for improved O&M. Ampt. String optimizer models are for system voltages ranging from 600 to 1500 VDC.

Ampt's patented features increase system ROI

Ampt String Optimizers have features that
lower the cost and improve the performance of PV systems.

String Stretch®
Ampt’s patented String Stretch technology puts voltage and current limits on the output of each optimizer which allow PV designers to double the number of modules per string. The output current limit removes the need for system designers to build in current carrying capacity margin for “over sun” conditions when specifying cable thickness, fuse sizes, and other component ratings while still complying with safety codes. This means smaller conductor sizing per kilowatt delivered. With Ampt, system designers save up to 50% on electrical BOS costs.
Dual MPPT per string
Ampt String Optimizers put two maximum power point trackers on each string. By distributing MPPT throughout the array, Ampt optimized systems mitigate or eliminate mismatch losses to deliver more energy under changing environmental and system conditions over the lifetime of the power plant.
Ampt Mode®
Inverters with Ampt Mode operate in a narrow input voltage range that is closer to the maximum system voltage. This allows the inverter to deliver a higher AC output voltage at the same current which raises the rated output power of the inverter. Delivering more power from a given inverter lowers the inverter’s cost per watt. Inverters with Ampt Mode are available from our partners. Inverters with Ampt Mode are available from our partners.
Direct-to-Battery
Ampt String Optimizers include power management technology for DC-coupled energy storage systems (ESS). Our Direct-to-Battery technology allows the optimizer, battery, and inverter to share the same DC bus without additional charging equipment dedicated to the battery. This feature enables storage systems with greater efficiency, flexibility, and scalability at a lower cost.
Wireless Communication
Ampt String Optimizers incorporate optional wireless communication to provide string-level data that is highly accurate, synchronous, and scalable to improve O&M, as well as enhanced controls for storage applications.

 

Ampt StringView

Ampt StringView® provides highly accurate and synchronous string-level data through wireless communication between an Ampt-CU and Ampt Optimizers. The Ampt-CU links to your monitoring system via Modbus. Ampt StringView® and the Ampt-CU are optional and not required to use Ampt Optimizers.

Ampt Module Optimizers

Small rooftop systems in shaded environments benefit from Ampt Module Optimizers which put MPPT on each module to maximize energy generation under mismatch conditions and can be either externally mounted (Ampt-x) or integrated inside the PV module junction box (Ampt-i)
