Thank you everyone for the great info. I've decided to go with a new Conderenergy 3kva Inverter, SVOLT 24v Lithium, 2x 425w solar panels. I dont think the lead acids are worth keeping around. At this point they are slightly better than paper weights

Hi @PsyCLown I had issues with them since the beginning. Although they were tested and confirmed in 100% working order. If I have the bare minimum running, they last 4hrs with a low battery warning ... I already wasted R6k buying the Royals. I just dont want to waste another R15k on a Lifep04 battery. Looking at the SVOLT 2.7kwh battery @madness_za My current cutoff is set to 21.1v (set by Rentech when they tested my inverter).

Hi All, I am new to the whole backup power / solar setup. Lately, I've been having issues with a Rentech 3kva (2400w) Axpert inverter. My initial installation was 2x JPC Lead carbon batteries in series (100ah ea) with the inverter. I was able to run 3x monitors, 2x laptops, TV, DSTV and PS4 for roughly 4-6hrs. That stopped a few months ago. I am barely reaching 2hrs right now. I replaced my batteries with 2x 105ah Royal Gel deep cycle batteries but the issue is the same. My overall peak load is usually in the region of 94-111w. On about 96w, I cant get through 2hr loadshedding. If I run 1x laptop, fibre router and 2x monitors I am get through 2hrs but with load battery warning within the first 1hr15m. It will stay steady on 22.4v. Now the inverter has been tested and they confirmed that all is in good standing with it and that the issue is the new batteries that I bought. I am planning on getting a lithium 100ah 24v battery but I am afraid of spending the money if its not going to solve my issue. The inverter testing was, amongst other things, tested on a lithium battery with 420w load and it seemed to work great. Any words of wisdom that might aid my decision? Thanks
