Our verdict

A conventional two-MPPT string inverter sized for a G98 notification: the datasheet gives a 16A maximum output current at a 3,680W rated power. Its 5,500Wp maximum generator power means a meaningfully oversized array is within spec. Maximum efficiency is 97.0% and the standard warranty is 5 years, with 10 and 15 as options. It weighs 17.5kg, which the datasheet calls a one-person installation.

Good

  • Under the 16A G98 line (max. output current 16A at 3,680W rated)
  • Two independent MPP inputs, two strings each
  • 17.5kg, a one-person installation
  • IP65

Watch out

  • 97.0% maximum efficiency, the lowest of the string inverters listed here
  • 5-year standard warranty; 10 and 15 years are paid options
  • No battery port
