Description
The inverter connects to one phase and weighs 17.5 kg, so it is wall-hung without lifting gear. Its 2 MPPT inputs take 2 strings each at up to 15 A per tracker, so two roof faces go to separate trackers. Maximum DC voltage is 600 V with 365 V nominal, and start-up at 125 V lets short strings on a small roof work too. ShadeFix adjusts operation when modules are partly shaded. The Smart Connected service monitors the unit remotely and notifies the owner of faults. The IP65 convection-cooled enclosure runs at 25 dB(A), indoors or outside, from −25 to +60 °C. The 3.6 version suits sites where the grid operator limits single-phase generation, and under VDE-AR-N 4105 the SB 5.0 is capped at 4,600 W.
How to choose
Choose the rating by array size, 5,500 Wp for the 3.0 and 3.6, 7,500 Wp for the 4.0 and 5.0, and 9,000 Wp for the 6.0. Check the feeder and breaker against output current, from 13.7 A on the 3.0 to 26.1 A on the 6.0. With a three-phase supply it makes more sense to spread generation with the Sunny Tripower 3.0–10.0, which keeps phases balanced and goes up to 10 kW.
