Not for me

Just checked, it's not back for me.

Yes, still the same here.

It has disappeared, for the 6 days I've been getting PVVoltLowWarn error which is undocumented. Growatt said it's a server issue which they were working on. The error which appeared every night just before and just after midnight has now gone but so has the History Data as you have seen. I'll...

Growatt doesnt support parallel / stacked operation.

Hi, I have a 6.7kW Solar PV, A Growatt SPH6000 Inverter and a Growatt 7kWh battery. I want to add another DIY battery with it's own inverter onto my system. Ideally the second inverter will be grid tied in the same way as the existing one, will charge the 16kWh LifeP04 battery during off peak...

Ive been burning my brain to come up with a solution, do you guys think this could work The second inverter on the right has it's own CT and battery but no PV. It would also have an RS485 comms link to a supervisory PC which will instruct it to charge the batteries and whatever rate it needs if...

I dont think I have the option with the Growatt inverter for them to work together.

Here in the UK its just a little different. If I buy from the grid I pay 29.2p per unit, if I sell to the grid I get 4.2p per unit. Thats why I need to get more storage etc to avoid paying 29.2p. J

I assume the defaults within the internal BMS of the Growatt battery, I cant see a way to get to that and I'm not sure chages at that point would help? I'm really wanting to AC couple a battery for several reasons:- 1) To get more inverter power into the system to cover odd peaks eg 2 ovens...

Hi, Thanks for the reply. I haven't put the 2nd inverter / battery together yet, I need advice on what's possible and what should be trying to purchase etc

I have a 6.7 kWh Solar Array, with a 6kW Growatt Inverter and a 7kWh Growatt battery. The system works beautifully and is easily capable of meeting my needs in the summer. In the winter however, this will be an issue. I'm trying to add another invert and battery to my system. I have read so...

So if I understand you correctly, fit say 20Kw inverter, battery and mains in to the inverter, the output goes to my fuseboard. The inverter will use the battery until depleted and then use mains either pass through or change to DC and use that mains to power the inverter?

Maybe I haven't understood how it works with solar? I believed that when you have solar panels if theyre generating say 2kw that 2kw is fed into your domestic supply and anything extra is supplied from the grid. So for example solar is generating 2kw, I turn on a 10kw shower, 2kw is supplied...

Thank you houseofancients and iMakerShop for your replies, I seem to be talking martian to all the suppliers Ive asked, none of them really understand what I'm trying to do. iMakerShop - you say you have to watch the loading to avoid a power outage, in my situation, still having a grid supply...
