I'm looking for some guidance on my LV2424. I've had this small off-grid system running smoothly for about a year. I've got 6x 240 W panels in 3S2P configuration, charging a battery bank of 4x 12 V LiFePO4 batteries, wired in 2S2P for a 24 V system. It's been great so far, after initial testing to get a good configuration set up. In the winter I rely on utility charging quite a bit (as I'm in Portland OR) but this last summer, the batteries charged almost to max every day from solar alone, which was great to see.
Occasionally I get a fault code of 04 (battery voltage too low), but this is fleeting as the batteries charge back up quick at that point because the utility kicks in. Normally it goes away after a short time and everything is fine again. However, today the same fault code appeared but I also noticed the load on the system (as seen on the display) intermittently (once per 45-60 seconds or so) spiked to 600-1000 W (normally I use about 150-200 W continuous). I checked all the circuits this system provides power for and only the typical 150 W for a small home office is being used. All other circuits have zero load.
What can cause a spike like this?
