Has anyone had issues with a Luxpower inverter at 00:00 each night?

Hi, I have a Luxpower Hybrid Inverter 6K [LXP-6K Hybrid] and it's been working properly for a couple of years but recently it's not been working as it should. I'm going through the support email address and they are getting back with the odd thing, but once they updated the firmware it's got even worse. They've not got back for a couple of days so I'm just seeing if I can find a way to get the damn thing to work.

 

The webpage interface has changed recently so I guess the issues may be related to this but it's been hopeless.

 

The recent issues are:

 

- using time slots and SOC to charge no longer works. Apparently this is a design issue but it used to work. Now you have to set the charge at night for period, or else set the system to charge when the battery SOC reduces to a certain level. So, for example, you can't now charge the battery to 30% at 4am-5am. It's a bit crap but hopefully it will change.

 

- the forced discharge stopped working, but now it is.

 

- the battery isn't used at 00:00 no matter what the battery SOC is. I've gone through every setting and can't for the life of me see any setting that should even lead to this happening (the battery isn't charging at 00:00, it's just not used). 

 

- Luxpower updated the firmware but now it's even worse! At 00:00 the battery gets changed at the max level. This is even when AC charge is disabled and all time slots are 00:00 (ie nothing is even set).

 

- all I can do is set the overall battery max charge level to something small at night, and then change it back in the morning so the solar charges the battery. This stops the battery charging but the battery still isn't used at 00:00. 

 

If anyone can suggest something that I could try it would be appreciated! I've pasted the main settings, both the new and old look options.

Just to add, in case anyone else has this issue - the system was apparently trying to charge at 00:00 due to battery callibration, where it tries to charge to 100% but couldn't as the limit is set to 96% so it kept trying. I never changed any settings but it looks like if you click on the "enable" to calibrate then you need to change the SOC charge limit to 100% until it's gone through one cycle.
