6 FAQs about [Photovoltaic inverter 09 code maintenance]

Why does my inverter always report error 09?

In most cases, if the Inverter’s IGBT or DC-DC MOSFET are damaged then the inverter always reports the Error 09 alarm. The inverter converter the DC power to pure AC sinewave . Hence, DC-DC MOFSET and Inverter IGBT are also frequent failure components. It could be due to the high AC surge or PV surge to damage these sections.

What are the voltage categories for off grid inverter?

There are 3 voltage categories for off grid inverter: 100Vdc, 145v and 500V. Error description in the manual: Bus Soft Start Failed. Resolution When the error appears you have to return the inverter to the manufacturer. If the main board is beyond repair, then a brand new inverter-board will be installed.

Which inverter is required for a combined PV and storage system?

Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).

What happens if a micro-inverter is not used in a PV system?

If micro-inverters are not used, the PV system will have both AC and DC components. The DC system determines system power capacity and energy production, whereas the inverter and the AC system has the greatest impact on system reliability.

What does fault code 09 mean on an axpert?

That would be U16; there is more than one UC3845 chip in an Axpert. Soft start partial schematic trace. Fault code 09 means that when the Axpert attempted to pre-charge the 400 V bus, it failed to reach its target voltage in 15 seconds. The target voltage is usually battery voltage × 8 but always 336 V to 480 V and it can depend on grid voltage.

Are string inverters a good option for solar PV system?

ilar to central inverters but convert DC power generated from a PV string.String inverters provide a relatively economical option for solar PV system if all panels are receiving the same solar radiance without shading. Under shading scenarios, micro-inverters may be considered as a more
