NEW – our highest power optimizer for 1000-volt systems used with higher power modules in new system designs or for repowering legacy systems.

Output power range: 17.6 - 29.2 kW
Output currents: 32, 30, 28, 25, 24 A



NEW – the mid-range power optimizer used for repowering systems with higher power legacy modules, replacing legacy inverters with modern 1500-volt inverters, or for new systems in smaller DC-coupled storage applications.

Output power range: 11.5 - 17.9 kW
Output currents: 20, 16 A



Our original optimizer for 1000-volt systems used with lower power PV modules for both repowering of legacy systems as well as new systems incorporating DC-coupled storage.

Output power range: 9.0 - 12.0 kW
Output currents: 13.5, 12.8, 12.0 A

Ampt String Optimizers Deliver Unmatched Value


Patented Technology

  • Dual MPPT per optimizer – delivers more lifetime energy
  • String Stretch® – more modules per string
  • High Fixed-Voltage Bus (HFVB) – save on capex
  • Ampt Mode® – increases inverter power density
  • Direct-to-Converter™ – lowers battery converter cost per watt
  • High DC/AC (3:1) – longer storage durations at a lower cost
  • V-match® – adapts PV plant to legacy or future power equipment
  • Wireless Communication – optimizes O&M with string-level data

Improved ROI

  • Reduce upfront total system cost
