- If I want to keep the battery happy for as long as possible, what should SOC settings be set to? I currently have the apex300 set to 20-80% but should I change this? Do I periodically need to discharge fully and go back to 100%?
- Will silent mode give better battery longevity than standard mode?
- I have an apex300 and b300k connected - currently at 80% combined SOC. However, if I dive in apex300 is at 87% and b300k is at 73%. Why do their SOC’s drift apart sometimes?

Are you actively using your Apex or just storing it? The manual explains on how to store it I believe. If actively using? might I suggest checking out self consumption mode. My Apex powers a garage fridge, you can set a desired SOC even if you don’t have solar hooked up. So say you set it to 70% the apex will not draw power from the grid until the battery depletes down to 70% and then it will draw power from the grid to maintain at 70%. If you do have solar then when generating and the batteries charging it will keep drawing grid power if necessary (fridge running) until 10% above setpoint. This gives you room to charge the battery from solar and save money. So I try to charge from the sun and get my SOC near 100% and then thru the night the apex runs my fridge without drawing power from the grid until 70% target is hit.
For your second question charging at slower speed is easier on batteries. I have mine set in custom mode in the app to just draw 5A (600W) I never see this though as my fridge draws 85 watts and that is what the Apex will draw to keep the target SOC in self consumption mode. Hope this helps, I had to watch hours of youtube to start making sense of it all. Since I dont have an expansion battery yet I can’t help on #3, but I watched enough youtubes to know that when you combine them the system is smart enough to calculate new SOC and will adjust the Display. Good Luck M8
