Growatt have confirmed “THe maximum AC output power of your SPH3000(PV+ battery) is 3kW, so if the load is greater than 3kW, e.g. 4kW, the remaining 1kW would be supported by the grid.” Clearly my installer was trying to get away with an inverter below the DNO approval level of 3.68kwh buy...

Thanks Gian I’ve been getting no reply from Growatt support I’m very technical myself & understand all the extra settings under the “growatt20220523” today password 😁 Coming from a software background I highly suspect that the v1.0 firmware needs an update as feels like a software problem...

Will do - thanks Its in Load first mode & should only switch to Battery First for 4 hours

And now this 🤷‍♂️

My Growatt SPH3000 Inverter is pulling from the grid when it can pull 3 kWh from the batteries but isn’t? Is it a bug or a setting? See pic attached. Thanks for any advice

Thanks 😊

Wonder if firmware also needs an update from base firmware? As it’s v1.0

I emailed them twice They come back saying which country are you from I reply And into the ether the query goes Not the best support so need to find a number Thanks 🙏

Ha ha yes you need a degree to translate this as Google would even suffer 🤣 It’s not at all intuitive on how to set these up even with the simple menus but I guess it’s tinker time as my installer is pretty useless supporting me Thanks for your help 😇

Trying to understand the Growatt SPH3000 via their Shine Phone app is a black art 🤣 see attached

Growatt SPH3000 inverter Why on earth is the stupid inverter pulling off the grid when there’s 11kwh in the battery 🤔 🤷‍♂️

Bulk do you know of a good guide to setup the growatt SPH inverters via Shine Phone or web interface? Some parameters not obvious 😁

Ours is a cool garage but the installer just offered us the SPH5000 upgrade 👍

Also my installer is claiming that under Solar Together any system less than 18 panels gets SPH3000 whereas over 18 gets SPH5000 Sound like rubbish to you?

Thanks Yes makes total sense 👍 Would the current inverter be at risk of damage being overloaded like this? What does it do with excess DC energy if it can’t store in battery or AC export to grid or AC use in house? Where does the DC go?

Here are some full example of how the inverter is not letting me maximise kWh generated I estimate I’ll loose out on 1,440 to 2,400 kWh a year due to inverter bandwidth as undersized for array

My setup is: - 17 x Q Cells Peak Duo Black ML-G9 380w Panels (6.46 kWh array) - 4 x Growatt PowerAmp ML33RTA 3.3 kWh batteries (13.2 kWh) total - 1 x Growatt SPH3000 6.6 kWh Inverter I’ve noticed that once the batteries are fully charged that : 1. The inverter starts to whistle 2. The...

Thanks for the reply I found this in the Growatt SPH3000 manual that concerned me

Hi I have a new on-grid system of: 17 x Q Cells Peak Duo Black ML-G9 380w Panels (6.46 kWh array) split over 2 strings 10 & 7 4 x Growatt PowerAmp ML33RTA 3.3 kWh batteries (13.2 kWh) 1 x Growatt SPH3000 6.6 kWh Inverter My inverter is not grounded & I’ve checked with my installer and they...
