5 Kw Multi plus inverter, Blue solar 250 / 100 charge control. My PV AC Thor. 5.2 Kw PV. 48v LiFePo battery pack 216 Ah.
The PV support assistant is not working well. In the morning the solar input charges the batteries up to absorbtion level. The Multi then increases the frequency, and the MY PV AC Thor sends power to the immersion element.
As soon as the batteries reach float level, the Multi reduces the frequency to 50 Hz, and the AC Thor stops delivering power to the immersion. For the rest of the day the frequency remains at 50 Hz even when there is plenty of surplus PV power.
Please advise how to improve this. The AC Thor is an expensive device, and it is frustrating that we cannot get help sorting out why it is not performing as it should in conjunction with the Multi plus.
