The Solectria PVI 14-20TL is a Yaskawa Solectria Solar family of transformerless three-phase string inverters made up of the PVI 14TL and PVI 20TL. The PVI 14TL delivers 14 kW continuous output at a nominal 208 VAC, and the PVI 20TL delivers 20 kW at a nominal 480 VAC. Both models accept an absolute maximum of 600 VDC. The MPPT range is 300 to 540 VDC on the 14TL and 300 to 550 VDC on the 20TL, with a per-zone input current limit of 25 A and 35 A respectively. Peak efficiency is 96.7 percent for the 14TL and 97.40 percent for the 20TL. CEC weighted efficiency is 96 and 97 percent. An internal arc board provides arc-fault shutdown (Arc Protect) and runs a self-check that raises Arc Board Error when it fails. Other alarms in the manual include GFCI.Err for high DC leakage current, GridV.OutLim for grid voltage out of range, EepromErr for memory faults and ExtFanErr for fan problems. The inverter has to be registered before its warranty becomes active.

Datasheet describes the models as transformerless three-phase string inverters.

review note: support check: partial - Datasheet title references transformerless 3-ph string inverters, but the passage doesn't explicitly state it's an inverter in the evidence text beyond the URL.
