Growatt 6.5 solar battery

25 Posts

Hi,
I have had the above installed as an addition to solar panels, but was surprised to find that the battery fills up overnight to 100%, so that in the morning - when the sun shines - my battery is already full.
As a newbie to all this it seems a bit daft to me, so I queried it with the supplier and he told me it's to take advantage of a cheap rate at night - but the tariff I'm on doesn't have a cheap rate at night.
So my logic feels that:
I asked my supplier how to do this but he told me to ask my neighbour (who is also a customer and recommended the supplier) !!
This whole installation has been problematic and I think he's 'had enough' of me asking questions
Happy for someone to tell me my supplier has been right to set to 100% overnight - but, please will you explain why?
Thanks

So my logic feels that:
- I'm charging at night costing me x pence / Kwh
- then exporting during the day and earning 'less than x/ Kwh'
which wasn't what I was expecting.

Anyway I can't find where 'Storage' is at the moment, but I have to work right now, so I'll look harder later. Thanks!
Sadly changing tariff is a whole other saga that I'm trying to get my head round as I can't get my FIT registration released from Scottish Power to go to Octopus - both parties say it's the other party's job. That's been going on for weeks too.
Solar Immersion installed May 2013, after two Solar Immersion lasting just over the guarantee period replaced with Solic 200... no problems since.
13 Feb 2020 LUX AC 3600 and 3 X Pylon Tech 3.5 kW batteries added...
In fairness to LR, they didn't do that on my install. They said I could charge the battery up at night if I wished, and emailed me the guide on how to do it.
My fit is still with edf who I left about 5 years ago.
If you don't have cheap rate, it's nonsensical to charge it at night, that's the companies fault for setting it up that way.
Also you paid them to install the system, so it is uo to them ti set it up right.
Who cares if you are that annoying so and so, you paid them for a service, not to think you are a great person.
They are failing you here, they should be fixing it
4kw sse since 2014 and 6.6kw wsw / ene split since 2019
24kwh leaf, 75Kwh Tesla and Lux 3600 with 20Kwh useable storage
I have now set it up for TOU overnight..
