Hi,
I am at my wits end!
For reasons unknown my system refuses to charge the battery overnight. If I set up a Forced Charge slot during the day it works no problem but no matter what I do it won’t charge at night during my cheap rate period.
It was working fine until the summer.
I have tried using the mode schedular to force the charge but it still will not.
I have also shut down the system and restarted but it makes no difference.
I’m thinking that there must be a conflict somewhere with mode schedular/forced charge slots - is there a way to reset all previous settings on the app/web page?
Anyone else come across this before?
When you say you are setting a Force Charge during the day, do you mean a schedule to Force Charge, or is it the Charging Time in 'Quick Settings' you are using.
Can you post an image of the schedule settings you have currently set please
Are you doing anything else at night - charging a car, running a heat pump, heating water etc..?

Hi Dave,
If I set up a charge slot durin ght eday it works fine, but not at night.
I heat a water tank at night via the IBoost - could that be the issue?

Which inverter is it, KH ?
Can you show your schedule settings with the overnight charge set so I can look for a conflict, also if possible can you post the graph from the app when you've tried to charge overnight - i.e. does it do anything even a low power charge ?

Ok I think your problem is that on the schedule for Force Charge you have set a MaxSoC of 10% - and as your minSoC is also 10% it won't charge at all.
Just as a confusion there are 2 MaxSoC's - one you can set in a schedule and the other is in the inverter settings which is only used by the old style grid charge and you cannot normally set this unless you have installer access.
The MaxSoC you set in a schedule is the maximum state of charge you want the battery to get to during the Force Charge, normally you'd pick 100% - although during summer some people drop it to ~60% so that there is space for solar charge.
When you have scheduler enabled it will disable the old style grid charge setting (you cannot use both at the same time), but if you were to disable the scheduler and instead use the Grid Charge Setting to charge your battery it uses the installer set maxsoc (usually 100%) and so will charge to full.
As you've only got an iboost I don't think you are exceeding the default import limits in the settings on latest firmware that can avoid the inverter drawing too much power from the grid (if you only have a small incoming fuse for example), these limits are adjustable but I don't think that this is the problem here.
I hope I haven't confused you with that slightly long explanation but to keep it simple if you just use schedules and have a maxSoC of 10% you're not allowing any charge to go to the batteries, set it to 100% and try it tonight - hopefully that'll work.

Morning,
So I Changed the max SOC and it refused to charge overnight.
Went back to scratch and set up as attached on Saturday - still not charging from the grid?

I’m clutching at straws a bit but have you definitely pressed the submit button top right as that without that it isn’t set and needs to be sent to the inverter - in the V2 app on the quick settings screen you should see Mode Scheduler say ‘Enable’
Yep, all set correctly.
Interestingly the battery charged from grid today between 2-4pm.
I’m baffled why it won’t charge off peak during the night?

Hmmm interesting, for the next bit can you go into the inverter settings and check to see how 2 options are set.
If you don’t have agent access to the app you’ll have to do this from the inverter front panel but go into ‘settings’, ‘on-grid’, ‘export control’ and see if you have entries for ImportLimitPwr and ImportLimitCurr - if you have those entries can you post what they are set to.

For some strange reason your import limit (power) is 10 watts, your current is correctly set to 100A - that means your inverter won’t take anything off the grid and the reason it charges during the day will be because you have solar generation which is being used instead.
It’s likely the ability to make these settings was added after your original install if you had the firmware updated but it’s unusual for the import limit to be set to that (unless you really don’t want to use grid power).
Can you change the ImportLimitPwr to 6000 watts, and hopefully you should be charging again tonight

Just posting a thanks as this seems to have solved an issue I was having as well.
When I went to look at the settings the importpower was on 0! Have changed it to 6000 and a quick 1 min test shows it is working. So hoping to test it out properly tonight- but thanks!
