Hi Jaco, The batteries are no older than 6 months. The default cut-off voltage on the inverter is set to 42v. The last screen shot is shortly after the power came on and it started recharging the batteries ... hence the 5% battery capacity shown as well.

Excellent thanks! So at half the battery capacity I should be getting around 5-6 hours? That’s kind of what l had in mind as to what it should be. Hopefully your settings can shed some light on my issue.

Hi forum fundies .... I'm new to the game and still figuring things out. I have an Azpert 5Kva Inverter, tied into the grid (no soloar) with 4x 12V 400W CSB Batteries (HRL 12399W) connected to give me a 48V system. My current load sits at around 15% - 18%. Its main purpose it to run my home based office during load shedding - so its mainly computers connected. The way my inverter has been connected to the DB board has been to isolate the home office and all the lights in the house so that at night we can have some light. Only the plugs inthe office are connected. There is no geyser or aircon or fridge. So my question ... how long (number of hours) should my system last before running our of battery power? At the moment I only get about an hour and a half which seems VERY short. Am I correct in saying so? How long should I get? See my settings attached .. perhaps there is something I have incorrectly set. Thanks in advance.
