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...

My location is across the pond in the UK in Lincolnshire. I have spent some time working in USA in Owensboro programming rolling mills though. I really like USA, lifestyle, people, cars all great.

Just checked, it's not back for me.

Not for me

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...

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 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...

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...

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

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...

I'm looking to build a battery storage system, I'm fine with all aspects of the battery side of things, the inverter however is a different story. My aim is to have 48kWh of storage and an 8kW inverter, what I'm hoping to achieve is a situation where the inverter provides my house power until...

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?

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

Yes, still the same here.

Hi, I'm a retired electrician / electronics engineer. With the horrendous hike in energy prices I intend to build a powerwall around 16Kw in capacity. I've fine with the battery side of things, I'm totally green with regards to inverters so I will be reading loads before asking daft questions. J

23,000 kWh per year, peak demand on Sundays is 8kW and that runs for around 5 hours I have a fairly constant base load of 908W. My energy tariff gives me 4 hours of cheap electricity (00:30 to 04:30 @ £0.05 per kWh, the rest of time is £0.292 per kWh) Thank you for your advice, apologies on the...

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...

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...

I'll get ready with the midnight oil and a cup of strong coffee LOL. Thanks - J

Growatt doesnt support parallel / stacked operation.
