@TheMac Yes I did ..same size . Its listed as a DO214AB SMD package .. 6,8 x 6.2 mm ..Hope this helps some other member ? Thanks for the feedback

@TheMacI am told the board was taken out some time ago, so that was a build up of dirt. The photo was sent to me

The 160V ones are probably a better fit, closer to the max input voltage of the MPPT board. https://www.digikey.co.za/en/products/detail/littelfuse-inc/smcj160ca/762443 Here's the listings from the Brightkey site. Maybe this will be useful info ? Regards

Thanks for the feedback @TheMac. Some further investigation shows they are SMCJ160AC or SMCJ180AC. This may help other techs. https://www.digikey.co.za/en/products/detail/littelfuse-inc/1-5SMC180CA/715091. This seems to be comparable. If any one has replaced these, please share your thoughts ? Regards

Hi guys, Can anyone offer any specs or equivalents for the TVS diodes as per the photo ? Any Info would be much appreciated Kind regards Cuan

Hi guys, (I hope this is the right place to post this query ? ) .. can anyone tell me the equivalent, or specs, of the TVS diodes used in the mppt PV imput, as per the attached Photo. Any assistance would be much appreciated. Kind regards

Regarding In-rush current, your inverter will have an NTC (Negative Temp Coefficient) Thermistor in the Input section. This limits the inrush current that the main capacitors require to fully charge. This NTC is found in practically all SMPS units (Switch mode power supplies). Regards to all

Just a note ..I have looked on Axpert and Voltronic , who apparently manufactures these units, but can't find any info ..

Good day Does anyone have service manuals/Schematics for the above inverter units. I see that the larger units are discussed often, but can't seem to find any info on these units Thanks in advance, much obliged for any feedback ? Regards Cuan
