ST10KWGT (10KW Grid-Tie Inverter, 550Vdc, 240Vac Output)
ST10KWGT (10KW Grid-Tie Inverter, 550Vdc, 240Vac Output)

Nominal 10KW grid tie inverter, can take solar input to 15KW, up to 550Vdc, up to 45.6 amperes. Output to 240Vac, 60Hz, 10KW, up to 28/18 amps, MPPT function to maximize solar energy capture. Wifi PV Pro app enables live power and historical power generation views. IP65, with double casing, inner casing is sealed to preserve dust and moisture protection. Many protection features, see below. High solar DC input voltage enables low current transmission to achieve same high wattage, hence thinner gauge wires can be used. Besides lowering cost, this also lowered fire risks. Similarly, high AC output at 240Vac instead of 120Vac, have similar advantages mentioned for DC.

Works with USA, Europe, and Asian grid voltages/frequency.

Solar Optimization: This inverter has MPPT function to optimize/maximize solar panels generated energy. In contrast some competitive inverters, eg, SolarEdge, requires EACH PANEL to have an optimizer. This raise system cost by about $50/panel, depending on the model. In other words, this inverter centralized the MPPT function into itself in contrast to other competitors' inverters which require the MPPT function be delegated to each solar panel's optimizer. Moreover, some of these competitors gridtie' inverters will not work (e.g. SolarEdge) without an optimizer attached to each panel.

Advantages over competitors:

  • Competitors would required two of their units to achieve 240Vac, raising system cost and points of failure.
  • MPPT is centralized in this inverter. This 10KW inverter has dual MPPT.You do not need an optimizer for each solar panel, e.g, SolarEdge inverters won't work without optimizer at each panel, which raises cost. Having an optimizer at each panel will prevent subsequent use of off-grid inverters with that panel array.
  • Future proof your lower wattage inverter, eg, 6000W to be upgraded to 10KW. This inverter will future proof your lower-wattage system, lowering total system cost over time.
  • Wifi monitoring of current and historical power generated. Not all competitors' inverter has this feaure.
  • Better heat dissipation and waterproofing, achieiving IP65 level.

For solar array with lower voltage input and wattages, please take a look at our 60Vdc-1000W, 60Vc-2800W, 500Vc-3000W, and 500Vc-6000W. You are welcome to visit us at Solartorrents for online User Manuals, Forums, & more.

Do not connect energized solar panels to any inverter because the sudden surge of current into inverter will damage your panels and inverter. Either do such connections before sunrise or after sunset. Alternatively, use our SparkFree device kill switch will enable anytime connections, sparks free, and safe for solar panels and inverter in daylight connections.
