Good day
I had a Smart Solar 150/35 that was making a very irritated high pitching sound when charging . I had the Unit Replaced by my Distributor . When the new one was installed I had the same problem . We have changed the Solar Panel configuration as the VOC was very close the maximum VOC of the Smart Solar. After the change the irritated high pitch sound was still there . I have contacted my Distributor and request a proper investigation into this . Before that could happen there was n burglary at their warehouse and the returned unit was stolen . I have offered them my current smart solar for testing purposes and proposed to have the unit changed with a normal Blue Solar 150/35 to see if the same problem persist .
I was supplied with a Blue Solar unit and installed it. There was NO high pitching sound anymore. I have Changed my PV Array to my original configuration and still the High Pitching sound was NOT there .
Al of this information was supplied to my distributor. Once again I have requested a proper investigation upon this as my client is adamant to have his Smart Solar Replaced . The client has welcomed the temporary fix but wants the Smart Solar replaced .
I have managed to bring this problem under the attention of Gerrit Tromp as Well as Andre Durand who are both Victron Employees in South Africa . Till today I had no response from them acknowledging the problem. I am in constant contact with my distributor and each and every time I am told they are waiting for Victron . I do not know how many times the distributor needs to do tests requested by Gerrit and Andre .
Out of my Business perspective i am sitting between the client and Distributor and I cannot every time respond that "they are working on it " .. I have requested from one of the projects manager from my Distributor that all I need is to confirm that if the High Pitch Sound is Normal . If the response is that it is normal the high Pitch Sound , then my question is why does the Blue Solar NOT have the HIGH Pitch Sound under the same conditions .
I do not have these issues with Larger type Smart Solar units 250/100 and 150/100.
I will really appreciate some feedback on how to deal with this as a can not continue to RMA units and not being satisfied . As well Labour and travelling cost are at my expense and the client will not pay for it .
