I've got a Multiplus 24 2000 and it works very well.
The problem I'm having is I lose all of the solar generated energy at the end of the day (let's say 2 kW) after switching from "Inverter" to "On". "On" will fully charge the battery and supply AC loads simultaneously. That's fine but I'm gaining nothing energy-wise as at the end of the day the Multi fully charges the batteries thus offsetting any solar gain. It would be best, I suppose, if the batteries weren't fully charged at the end of the day (or a certain SOC or battery voltage)
My only thought is there must be a solution to this problem.
How can charging be prevented when the batteries get low in SOC (any value but zero)?
I think the ideal would be to run on inverter throughout the day and then at the end of the day (no more sun) switch to Grid but let the batteries remain at whatever charge level they are at the end of the day then let the following day's sun charge them back up.
Any ideas?
