App is shocking.. I now use Solar Assistant to monitor everything which is far superior. But other than that it's behaving exactly as it should. Battery charges when there's excess solar and discharges when I need it.
SPA3000tl AC coupled inverter and GBLI6532 6.5kWh battery installed Apr2022. Initially the battery faulted once it reached 100% for a couple of days in a row, but worked fine once reset. Since then has been running fine and doing exactly what it's supposed to. I'm guessing the BMU needed a couple of charge cycles to calibrate. I contacted support about this but received no help. Since it started working properly I never chased it up and they haven't either, so support is poor. Great value system though and significantly cheaper than other options I was quoted for (several £k cheaper). The monitoring and control software is beyond poor. If you're a data junkie like me it will do nothing but frustrate and disappoint you. I've since switched to "Solar Assistant" software installed on a Raspberry Pi connected to the inverter. Works incredibly, and more support is being added for my inverter all the time. Real time monitoring is amazing with data points recorded every 10s unlike Growatt which is every 5 minutes. Also it's not dependent upon Growatt's servers which are always down. If Growatt had better software and a competent UK support I'd recommend them all day every day. As it is, you get what you pay for I'm afraid.
