I'm sure there's a simple answer to this but when overnight charging, I have 7 hours of "cheap" electricity and have therefore set up a forced charge during this period. I also run my immersion heater, the washer, a dishwasher and towards morning my electric heating. Last night was my first overnight charge and being an insomniac I got up to se how things were progressing. Initially the inverter charged at about 3.6kwh ( i have 15 kwh battery capacity) but when I put a load on the system this reduced so that the mains draw was no more that 4kwh. When I put the immersion on and some heaters the battery discharged tomaintain 4kwh mains draw, I've tried for hours to find some setting to change this but no luck so far! Help!
Can you provide a few more details please, what size/model of inverter is it, how old is it (i.e. if last 18 months it is a generation 2) and which model/number of batteries do you have fitted
Hi,
It was installed yesterday, sn60wc5020558b012, I have 3 x 5kw batteries with a total capacity of 15.54 kwh. Is that sufficient info?

Hi Bill,
Dave was looking for Model names for your Inverter & Battery
Example Inverter: KH7
Example Battery: EP11
If you have Fox Cloud 2.0 app on your phone, then you should be able to press Device (bottom middle) and take a screenshot or write down details.

The first thing to say is that assuming you have EP5 batteries your maximum charge power would be around 5kW @ 25C derating as the temperature falls, but if your charge power was being reduced to stop excessive grid import, it is possible the import power limits are set incorrectly.
At the inverter panel go into Settings, and look at On-Grid, Export Control, ImportLimitPwr (set this to 30000), and ImportLimitCur (set this to 100A) - these control the maximum allowable power you can pull from the grid so if you have lots of high power devices this would need to be set appropriately or the inverter will throttle it’s charging power as they increase their demands.
