Looks like more info/sales pitch here? : https://www.magnetoenergy.co.za/wall-mount-5-5kwh/

In the end I built this to measure and control everything...

Thanks all, will unsubscribe from those threads.

What?

I think there is more to it...

Hi All Are you also getting spam from the forum every so often? Thanks,

Thanks for the sheet! I tried it, works well! Why are there 13 months?

For now I'm running MultiSIBControl app with 2 rules at 5 minute intervals. 1) Switch to Grid if: Grid is available AND Battery SOC is below 99% AND Solar input is below 100W 2) Switch to solar if battery SOC is above 99% between 08H00 and 16H00 The last 2 days it worked well to prevent battery power being used.

I have an Axpert/VM-3000 inverter, panels, lifepo4. As soon as it starts getting light in the mornings, about 1.5 hours before the panels can produce usable energy my inverter switches over to solar/battery, same in the afternoon, the last 1.5 hours of daylight does not produce much energy. I don't want the inverter to use battery power. It must use solar when enough is available to power the load, and switch to Utility when PV input falls below what's needed. I don't want it to use battery power as it adds cycles on the batteries. Where do I go from here: Add a timer switch on the PV input wires, and only connect the panels to the inverter during the hours I know they can power the load? That leaves the issue of cloud cover during those hours when it will use battery till "Back to grid V". Back to grid is 25.5V max on my inverter, so it will drain a lot from the batteries before switching back. I can write a small program on a PIC or Arduino to look at the batt V, or pull data from inverter to see when PV W fall below a certain threshold, and disconnect the panels to force it back to grid. In case of cloud cover it can retry to run from panels in x minutes to see if enough power is available? Many options. What do you think I should do?

Yes you are right, I will try not to worry about it anymore.

I have this one from Takealot. https://www.takealot.com/oci-vm-value-3kva-2-4kw-1kw-mppt-102-vdc-hybrid-off-grid-inverte/PLID72935564 Thanks, will have a look at Kodak models.

This 27.6V is driving me up the wall. I borrowed 2x 100AH lead acids, still the same. Maybe I should return it, my mind can't switch off if everything is not in perfect order.

I have a 24V OCI 3kva/2.4KW inverter. The first few times it recharged my LifePO4 batteries in bulk mode to 28.4V as per setting, then it suddenly got this same issue, it will only bulk charge to 27.6V and go to float. I am charging from utility power only, no panels. After much reading and pondering..... I think for me the 27.6V thing only started after I installed WatchPower software, and used it to change a parameter on the inverter. Maybe it changed some value in the background that it's not supposed to? Did any of you with similar issue use the software?
