How to getthe best out of Octopus Flux
- Thread starter Ron-ski
- Start date
You can get a 3kW Solis AC charger inverter for about £700, couple of forum members are using them.
What wattage panels?
They appear to do different power versions of the S5, but the most it will be is 3.6kW.

its monthly for me when they pay me out via my bill

ive looked at using a company called L&R Renewables if i do go down the ac coupled route in the future. As the price includes installation and documentation too.....i know its done right then, i no like messing with this type of electrical stuff lol
@Welshman if you're getting someone to do it, I would suggest looking at both options, AC coupled and changing the inverter, DC to DC batteries is more efficient

its a long way off yet ron-ski, i only had my system fitted 6mths ago…..@Welshman if you're getting someone to do it, I would suggest looking at both options, AC coupled and changing the inverter, DC to DC batteries is more efficient
You can use an app, either Octopus Watch or Octopus Aid, then you can usually see the next day.
Tuesday was my first day on Flux export, although it shows in the Octopus App, Octopus Watch doesn't show any export, but I actually exported 19kWh on Tuesday, so usage should be zero, cost will depend on the export/import prices.
Fairly safe to say my bill for the last week is -£16 roughly.
Do you have to log into separate accounts, or do they both show in the same web account?
Octopus watch uses the API key, so if its different web accounts it will be different keys.

just had the ready to go email. just need to tick the boxes to accept the Ts and C's and it will be good to go from midnight the day I do that.... I have 28 days to accept the terms so may as well wait till the 23rd and get all the 14p peak, 5.5p off-peak and 25p standing charge I can.
Same account no. Will keep an eye on it over the next few days.

it's pre coffee so it's probably me being really dumb but..... either my maths are wrong or octopuses maths are wrong. (I am working out how long to leave it before signing my flux "paperwork" as my flux will go live when I do.
for reference right now it's 7am on the 19th.
my contract ends on the 23rd (presumably midnight):so by my reckoning I have 3 and a a bit days left however according to my account.

Hi
I can't find the post now but someone said I should be able to set my solis inverter to hold the battery at a set percentage thus helping me get the most out of flux but I would likely need a bios upgrade.
I have got the bios upgrade, however am struggling to find out how to do it (I would like to charge my battery from 2-5am then run off battery until it hit either 75% or the sun could take over.
however looking at the settings it seems I can either charge the battery, leave it undefined (so will discharge as demanded by the house or charge off solar) or force discharge to the grid
but I can't find a way to hold a charge at a set level and then run off the grid if needed but NOT charge the battery.
what am I doing wrong.
image attached. thanks.

It was me, do you have "schemes" or anything like that, eg self use, import priority things like that?
Mine has one for exporting peaks called peak shaving mode that seems to allow (i havent tried it) to set a minimum SOC and export above that
They are all kinda diff but I think Solis and Solax are basically the same

thanks..... i have been through every setting and cant find anything... it is ok, not a show stopper, i will just have to hold at 100% till 4pm unless somoene else with exactly the same inverter could hand hold me through it.
i did find the forced cut off on my battery discharge tho at 20%... am a little tempted to drop that to 10% and get another .7kwh out of it.
Soldato
Could your inverter is older and hasnt got that option.
Some of the older batteries I believe had a lower limit of 20% so it might be you cannot go lower. Probably worth googling them and see what they say.

maybe.. i would hope not however as it was only installed june 30 2021 i will investigate more however, but not in a rush. thanks again.
when i google the model number this is what i get

however the buttons on the front, whilst in the same position are a slightly different style and are grey with a grey border around the screen so perhaps the older model of it.

I find it better to just charge between 2 and 5am, then run off the battery until solar takes over.

Oh for some reason I thought you had inherited a system.
Its almost certainly 10% then
