Inverter to high output panels

[guruji]

Hi guys I have 34v output solarpanels and want to hook it to a 12v-22v inverter. What should I do to lower their voltage?
Thks.

You could try looking in the connection box on the panel - if it gives access to the midpoint of the panel - i.e. 17v then it may be possible to electrically split the 34v panel into 2 x 17v panels and connect in parallel.

Otherwise it may be simpler trade in either  the inverter or panel for compatible ones?

Or use an MPPT controller to drop the voltage - but this may be an expensive solution and electrically inefficient as your converting voltage twice.

Hi mab thks for response. This is just for temporary usage cause had another inverter and trying to fix it but cannot find equivalent mosfets to it ITA25N50R.
Thks.

MOSFET is a 25n50R(r maybe reverse pin out?) a Chinese part... good luck finding one...
