Description

Product positioning jig Technical Field The utility model relates to the field of assembly production of photovoltaic inverters, in particular to a product positioning jig. Background The photovoltaic inverter (PV INVERTER or solar inverter) is an inverter capable of converting a variable direct voltage generated by a Photovoltaic (PV) solar panel into a commercial Alternating Current (AC) with a mains frequency, and can be fed back to a commercial power transmission system or used by an off-grid. The photovoltaic inverter is an important device in a photovoltaic array system and can be used with common alternating current power supply devices. The photovoltaic inverter mainly comprises an IO plate, a BUS CAP plate, a communication plate, an INV main plate, an LLC circuit board, a DC plate, a RY circuit board, a BYPASS protection plate and other circuit boards.
