I have 600VA, 12V Pure Sine Wave Inverter (Atleast under no load, its pure) having 8 IRF3205 Mosfets in total. (In full bridge configurtion)

I have modified its shunt. Now it do not give overload error even when operated at 1000VA (Tested for short duration).

Q.1. How much power can i pull from it with same number of mosfets with 2000VA transformer?

Q.2. How much more mosfets should I connect to pull 2000VA from it. (I can make all pcb traces and wires thicker, its an easy task. Battery bank can deliever 2000w easily)

  • \$\begingroup\$ Can you give more information? What voltages are you working with? Do you have a schematic? \$\endgroup\$ – Clipboard_Waving_Enginerd Apr 2 at 13:20
  • \$\begingroup\$ Battery bank is 12v lead acid. \$\endgroup\$ – Vikas Kumar Apr 3 at 14:54
  • \$\begingroup\$ Inverter output 220V, 50Hz. \$\endgroup\$ – Vikas Kumar Apr 3 at 14:54
  • \$\begingroup\$ Transformer has only 2 wires on 12V side and is in H bridge configuration. \$\endgroup\$ – Vikas Kumar Apr 3 at 14:55
  • \$\begingroup\$ 2 Mosfets at each leg of H bridge. So total 8 mosfets. Mosfets are rated for 110A at 25°C. \$\endgroup\$ – Vikas Kumar Apr 3 at 14:56
