Damage to appliances after Solar installation


Question

Hi, I need some advice please: A Goodwe 4.6 Kwh Hybrid inverter was installed at my house late in 2020. Shortly after I had two fridges, an alarm system and the automatic gate motor damaged. Seems like the transformers and fridge compressors specifically sufferred. These are equipment that I had for a long time. but put them on the inverter output as part of the installation. Needless to say, after repairs it now happens again and again, even after I put in spike prevention plugs. Damage happens together with loadshedding occurances, I think. The installer is quite slow to assist and I would like some advice in handling the issue. Will appreciate.

So your fridges etc are all on the backup side, do you have batteries?

Not all, but two small small bar fridges are on the backup side. I have two Pylon batteries 2.4Kwh ea. 4.8 Kwh total capacity backup. Not for a functional reason, rather bacause the electric circuit where the two fridges are also have the TV to be powered during backup times.

Hi

Im not fimiliar with your inverter brand and how its setup.

I had simular situation and i discovered it was due to the transfer time of inverter from grid to battery (most inverters is round 10-20ms). That quick dip is not good for the comperessor motor of fidges while its running.

Hope it may shine some light on your situation.

 

Regards

This might be it.. I will take up with the installer.

Fridge motors are usually quite robust. Hard to cook them with start up/change over spikes.

I would suspect a waveform issue on the inverter.  Easy to test if you have the right equipment, impossible if you don't...

I read up on the wave form issue and according to the information I obained about the Goodwe Inverter is that it has a true Sine Wave. So it seems not to be the problem

Was it a pre-existing condition or is it something the installer of the Goodwe worked on?

The problem started after the installer worked on the wiring. The equipment that is damaged runs from the inverter at all times. The issue did not exist before.

It should be pure sine wave... Damaged output drivers or output filter could provide a really nasty waveform.

Sure! But this kind of insurance works well. They will most often pay for the damage incurred and this is a comfort.

You do need to establish what is causing the damage however. I have seen rented industrial electrical monitoring and recording equipment that is installed on site a for some time that allows analysis of that supply. A bit pricey I'm sure but it does exist!

What I recommend you do is to connect a multimeter that has min/max readings to your supply. (The newer Fluke meters can do this) It will then measure and display the maximum and minimum voltage whilst it's connected..
