Yes it was covered, this time both the MPPT board and Main board were changed. The installation seems compliant but now I'm closing the inverter when the humidity level is too high and will build a ventilated aluminum and clay cooled cabinet around.

Well believe it or not. My Growatt board fried for a third time last night. Now I have lost all my faith in this inverter brand... not sure what to do next.

Not only breakers, Surge protectors which is not the same. My breaker jumps only since there is an AC surge protector.

You know what? Mine fried a second time at the end of August. I have been told that Sri Lanka have received a bad batch and are fighting with warranty. Anyway, I also noticed that my installation had no SPD on the AC side, only on the DC side. So I have gotten the AC side fused. Since then the breaker has jumped twice on CEB spikes which I like to believe saved my board from frying. I also got a breaker installed between my batteries and the inverter to be able to completely shut off the inverter in case of emergency. I think those should be part of any installation but learning is still in progress for the providers.

Yes they should definitely have changed the model naming to make this clear. A lot of people are buying this model because of its scalability. This is our case and we are thinking to have electric vehicule in the future. Not knowing this point could have ended in us buying an incompatible Growatt spf5000es thinking they all can be paralleled..

Thanks Hansa. We have got the whole system professionally installed by a local solar company here in Sri Lanka. But will definitely consider getting a electrician coming if we observe any additional uncommon behaviors. I consider getting a soft starter on the water heater also just to make sure it does not spike on start.

Thanks for your input on this. Yes I think everything will be repaired under warranty as I declared this problem in a Whatsapp group with my installer, the local Growatt importer and 2 managers at Growatt in China 😉. I also notice the battery being used without need. And sometimes a little load going on the grid even if there is plenty available on solar and being in solar first mode. My biggest concern beside this incident is that my firmware number does not look like anyone posting here. I hope I will be able to benefit from firmware improvements in the future and also being able to parallel another Growatt inverter to my system.

Hi I have got installed a Growatt spf5000es on July 4th 2022 and two night ago (18 days after installation) it stopped in the middle of the night and started to spark as trying to auto restart. Today the technician came and took the whole inverter back to his atelier for repair as the MPPT has a fried chip and this whole part needs to be replaced. I asked the reason it could have happened and he said maybe an overload. Now at the moment it stopped, they were only 600watts load on the inverter, my bedroom AC at night. Also looking at the stats since I have the inverter, the it rarely went over 3000 watts load for long period and had a one time spike at 4200 watts. I'm curious to know if anyone else had a fried MPPT and what happened after the repair. I'm still a Growatt enthusiast but this event makes me want to know if there are downsides to this inverter.

I was wondering why my firmware was different than anyone else on this forum! Does that mean I have the batch that canno't be parallel with older version? By the way, mine just fried 18 days after installation, the MPPT board is being replaced at the moment. See attached pictures.

Hi Growatt enhusiasts, I have a brand new SPF5000ES installed last week and I am getting these numbers for the firmware which does not look like the ones circulating here 40,41+ Could someone share with me the most recent firmware? Thank you so much!
