Growatt Solar batterys?

Does anybody rate Growatt solar batteries? I'm looking into getting a solar pv system with batterys, have been quoted by one company which are offering 2x6.5kw batteries as part of the package.

Bit hesitant as I understand their inverters aren't great and their customer service is non existent?

    I have 1 x 6.5kWh in my setup, does what it does with no fuss. You can get through to Customer service/support if you try, my main gripe is with the Growatt reporting solution as I've documented previously.

    I had a Growatt AC coupled system fitted last week with 6.5kWh battery. It was a steal compared to other systems.

    Everything seems to be working well.  Took a little bit of fiddling with the iBoost to get them working together (changed iBoost to 200w export threshold) but other than that it's working as expected.  Importing <1kWh a day most days even with the clouds.

    I think my only complaint would be the app.  It's slow and doesn't update regularly enough for my liking.  The web portal is better but has some ridiculous spelling errors, my battery is currently 'charing' for example.

    I would strongly suggest avoiding Growatt - terrible after sales support and quality is hit/ miss. The phrase you get what you pay for is exemplified here. 

    Stick with reputed manufacturers like LG/ SolarEdge/ Givenergy 
    -  10 x 400w LG + 6 x 550W SHARP BiFacial Panels + SE 3680 HD Wave Inverter + SE Optimizers. SE London.
    -  Triple aspect. (22% ENE/ 33% SSE/ 45% WSW)
    -  Viessmann 200-W on Advanced Weather Comp. (the most efficient gas boiler sold)

    Feel free to DM me if I can help with any energy saving!

    Maybe it's too early for me to have a valid opinion, also my inverter and battery is AC coupled, which may make things less likely to go wrong but I think peoples expectations can be too high with regards to reporting software.

    My PV inverter is an SMA sunnyboy.  SMA are one of the top PV manufacturers in the world.  German made so high quality! 

    The web portal looks like it was designed 20 years ago, probably was, it hasn't changed in the 8 years I've been using it.  The app is terrible, a lot of the time it claims I'm generating 0w, so is largely useless if I want to quickly check if I can put the dishwasher on.

    You mention Givenergy as a reputed manufacturer, it was one of the quotes I got, and I undoubtedly would have gone with them if they ever had any stock in the country, but I joined the Givenergy facebook group before buying and it gets several posts a day with user problems.  Maybe anecdotal, but it doesn't fill you with confidence.

    What you also have to remember is generally people only place review posts when there is a problem - for every issue there are many that have no problems whatsoever.
