Power One Aurora Inverter TL 3.6kW 208/240/277 V

Transformerless inverters require that all PV array wiring (including PV module output cables) use double-insulated wire, and combiner boxes (if used) must have fusing on both positive and negative conductors.

Power-One's Aurora PVI inverters have dual input sections to process two strings with independent MPPT, precise MPPT algorithms for real-time power tracking and high energy yield, as well as high performance efficiencies up to 97%. Two input sections and independent MPPTs optimize power from two subarrays that can be oriented in different directions, with different string sizes, or with different PV module models. The inverter will track the optimal power point for each of the two arrays independently. Both MPPT sections can also be paralleled for use with a single array. The wide input voltage range allows for low wattage installations with reduced string sizes where needed (strings as short as four 60-cell modules are possible). Combined with the dual independent string inputs, this wide voltage range lets you use two strings with different numbers of PV modules in each, greatly expanding possible array layout possibilities.
