September 10, 20233 yr Hi guys. I have an axpert/voltronic MKS-3KW inverter with the MPPT charge controller. I’ve recently installed 2 solar panels connected to this inverter. The max PV input is rated at 600W which is very little however I hardly pull over 500W during the day. I have it set up to SOL as output priority however I’m trying to figure out exactly how this mode works… My understanding from the description is that the inverter will power the load with the PV power generated, and if not sufficient it will use battery power at the same time to fill in the needed power. However what I’ve noticed is that the LCD display shows a small amount of battery power being used even if the PV input is greater than the load demand. The power from the battery being used is not a lot, usually around 5 amp and fluctuates sometimes. An example of this situation was yesterday, where my solar panels were producing the inverters max input of 630W, and my demand load was approximately 500W and I would have assumed the inverter powered this load straight from the panels however the batteries were being discharged a small amount as well. I am just trying to figure out why this is the case and if there is any settings that I have wrong. I ideally want the PV panels to power the load, and only use battery power if the panels are unable to provide the full demand, as stated in the manual. Im new to this and might not be able to explain to the point 🙏 I will try my best Thanks guys
