In fact when the device tripped correctly, but the cause is weather related and qucikly clears.
Our solar panels are tempermental and when rain/water contact some where, it trips. It is impossible howver to identify the panel (there are 24) and relevant cell in the panel.
What is tripping today? Since you are looking for an RCD device is it that you do not have an RCD today or you have one but it doesn't have an auto reset feature? If the latter is your problem that the existing RCD is tripping? Where is this RCD in your panel? Is it the main breaker or a branch circuit?
"...Reduction of unwanted tripping....that are typically generated by inverters and the main cause of unwanted tripping of residual current devices..."
So maybe it isn't weather related but the high frequency of your solar system inverter is tripping the RCDs. So if you are not home can you disconnect the solar? Surely your load is low when you aren't home. Alternatively maybe the inverter company can sell you a filter to put after the inverted to stop the noise and harmonics from coupling into you power system and tripping the RCDs. Lastly power these sensitive things like refrigerator and fish tank from branch circuits not protected by the RCD so if it trips these items can stay up. I think you have several options instead of a resettable RCD.
Not clear what your problem is so hard to give helpful clues. Also RCDs are not common here (an solar is not plentiful either, however growing) but seem to just be a GFCI of some sort.
