C2000^™ Solar Inverter
Development Kits
Jump start your solar design with development kits for micro, central and string inverters
C2000™ Solar Development Kits provide
instructive development platforms for
design of highly efficient and reliable solar
inverters, including central, string and
micro inverter topologies. These kits en-
able designers to jump-start solar inverter
designs using leading technologies found
in the solar industry today.
Solar development kits offered today
­include:
• Solar Micro Inverter Development Kit
• Solar DC/DC MPPT Development Kit
• Solar AC/DC Single Phase Inverter
Development Kit
• Solar Explorer Development Kit with
F28M35H52C MCU
• Solar Explorer Development Kit with
Piccolo TMS320F28035 MCU
The Solar Micro Inverter Develop­
ment Kit is based on the Piccolo™
TMS320F28035 microcontroller and
serves as a complete grid-tied solar micro
inverter. The topology of the micro inverter
consists of an active clamp fly-back DC/DC
converter with secondary voltage multiplier,
maximum power point tracking (MPPT),
and a grid-tied DC/AC inverter. The single
Piccolo MCU functions as the controller for
the complete inverter, including control of
both power stages, and MPPT execution.
The Solar DC/DC MPPT Develop­
ment Kit is based on the Piccolo
TMS320F28035 MCU and serves as a
DC/DC converter with maximum power
point tracking (MPPT) for central or string
inverters. Its companion kit, the Solar
AC/DC Single Phase Inverter Develop­
ment Kit, is based on the F28M35H52C
MCU (alternatively supports the Piccolo
TMS320F28035 MCU as well), and serves
as a full-bridge, single-phase, grid-tied DC/
AC inverter for central or string inverters.
Together, the Solar DC/DC MPPT Develop-
ment Kit and the Solar AC/DC Single Phase
Inverter Development Kit operate as a
complete central or string solar inverter.
The Solar Explorer Development Kit
is designed as a low-voltage learning
Solar DC/DC MPPT Development Kit
and Solar AC/DC Single Phase Inverter
