Fronius IG Plus 2LT-2 6kW Solar Inverter Teardown
« on: June 14, 2024, 09:40:33 PM »
A teardown of a 6 kW solar inverter, the Fronius IG Plus 2LT-2. Two phased system split into two inverter boards, based on TO-247 devices in the power electronics section.

The 2LT-2 model is connected to mains grid on two phases. The inverter is made up from two identical single phase inverters, connecting to L1+N and L2+N. Each inverter capable of 3 kW output power, for a total of 6 kW. A qualified guess would be that the 3 phase version can output 9 kW.



All magnetic components are nicely placed on a metal plate on top of the heat sink tunnels. Whereas an internal fan cools the magnetic components with the surrounding air.



To sum up the power electronics, it's MOSFET to Schottky Diodes to IGBT. Firstly it is Microsemi APT94N65B2C3G MOSFET driving a isolation transformer from Solar DC BUS to boost voltage. APT94N65B2C3G specifications: 650V, 94A, 282A pulsed, on-resistance of 35mΩ and total gate charge 580nC. Secondly rectifying diodes is Cree Schottky C2D10120 with specifications of 1200V, 18A and 100A pulsed. Thirdly it is Fairchild FGH40N60 IGBT FGH40N60 from boosted DC BUS to output inductors. FGH40N60 specifications: 600 V, 80 A, 120 A pulsed, Vce(sat) voltage of 2.5 V and total gate drive energy 1.61 mJ.
