Original install was 2 x strings of cells, 2 x SPH500TLBH inverters one of which had 2 x GBLI 6532 batteries.
What I wanted was to parallel the two inverters so each could have a battery and would give me 6KW total discharge
But, you need a SPH500TLBH-UP inverter to parallel and a SEM to manage them.
Anyway, I managed to get hold of them and got them installed and after a lot of faffing with Growatt support got them talking to the batteries and both talking the SEM, then overnight one wont talk the SEM anymore.
Lots more problems, the main one being PV voltage too high on both inverters and Grid voltage errors on one.
OK, so revert back to old system and I'm still getting PV voltage too high errors. It's reading upto 560V and spec is 550V. But I haven't played with the panels and it never did that before. Any ideas what I have done?
Failing that, I'm fed up with Growatt and would like to replace the two inverters BUT keep the batteries. So, any suggestions on a single inverter or a pair that will work with the growatt batteries, have a maximum PV input of 600V, and give me at least 6KW discharge from the batteries and let me limit export to the grid to 8KW and to add the cherry on top would allow me to monitor locally without the need to connect to a remote server???
Any thoughts would be appreciated
