Ampt String Optimizer V1500 Series

Chapter 1:
Product Overview
Ampt String Optimizers are DC/DC converters with multiple features that lower the cost and
improve the performance of new and existing PV systems.
•
Dual MPPT per optimizer
- Ampt String Optimizers put maximum power point tracking on each of
its two input strings of PV modules. This mitigates or eliminates mismatch losses to deliver more
energy under changing environmental and system conditions over the lifetime of the power plant.
•
High Fixed-Voltage Bus (HFVB)
–
Ampt’s advanced DC power management technology allows for
HFVB system designs which turn the variable voltage of the PV array into a fixed and predictable
DC bus voltage to achieve system-level economic advantages. HFVB designs lower the cost per
watt of inverters, battery converters, and trackers while reducing ampacity requirements and the
number of home runs. Ampt’s HFVB technology can also restore lost revenue from
underperforming systems suffering from “voltage sag.”
•
Ampt Mode
–
Inverters with Ampt Mode
operate in a
fixed or
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 to lower the
inverter's cost per watt.
•
Direct-to-Converter
–
For DC-coupled energy storage systems, Ampt String Optimizers include
Direct-to-Converter technology which allows the DC bus to operate at a higher fixed voltage so the
converter only needs to buck when charging and boost when discharging. This simplified
operation reduces battery converter costs by up to 50% with less circuitry and a higher power
density.
•
High DC/AC
–
Ampt’s unique combination of output current limits and a higher DC bus voltage
allows PV system designers to achieve optimal DC/AC ratios (up to 3:1). With Ampt, system
owners can expand the DC power on existing systems without replacing inverters, combiners, or
cables; optimize inverter utilization on new systems to lower the cost per watt; and lower capex
while increasing storage durations on systems with DC-coupled energy storage.
•
V-match
–
Ampt’s patented V
-match
technology allows the output of our optimizers to match
the DC bus voltage set by the inverter or battery while delivering full available power from the PV
modules. This uniquely allows PV arrays with Ampt to automatically adapt to legacy or future
power equipment to repower existing systems, upgrade inverters, mix new and legacy PV
modules, deploy optimized DC-coupled storage systems, and other applications.
•
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.
