I changed the battery cutoff to 46 V, thanks. Will keep an eye on it Anxiously waiting to find out how to "unfreeze" my PV input

Is this what you need? I forgot to mention, when the inverter stops charging from solar I need to change the Charger source priority to utility and back again to Solar only and then only will it start charging again. In the example I provided I caught it by chance and changed it back quickly. On previous occasions it would simply stay like that.

Good evening I have an Acpert RCT 5K inverter (5kW/5kV) with 12 x 330W panels and 4x Vision HF12-890W 12V 200Ah batteries The inverter was repaired under warranty on 3 March 2020. "Replaced the MPPT Charger PCB" was indicated on the Service POD note Since then the Inverter has not operated the same as before. It will stop charging from the solar panels or switch to LINE mode unnecessarily as can be seen in the attached Watchpower screenprints. I have also attached photos of the information sticker on the side and the home screen indicating the firmware version Can anyone please advise me if the inverter can be reset in order to clear the "bug" or if a better firmware version is available and how to install this. Regards Gerrit

Thanks Coulomb. Appreciate the feedback once more I am in Pretoria, so summer does get hot! Gerrit

Good evening I have an Acpert RCT 5K inverter (5kW/5kV) with 12 x 330W panels and 12x Vision HF12-890W 12V 200Ah batteries (Spec sheet attached) 1. The charging specifications are: Cycle use 14.5-14.7V Should I set PROGRAM 26 (Bulk charging voltage) to 14.5*4 = 58V? (Seems a bit high from the 56.4V default!! Standby use 13.6-13.8V Should I set PROGRAM 27 (Float charging voltage) to 13.6*4 = 54.4V? 2. Is it possible to install a BMV 702 battery monitor and link it to the Acpert inverter without the ICC software? Thanks, Gerrit HF12-890W.pdf

Hi I have an RCT-Axpert 5K inverter with 12*330W JA solar panels in 4strings and 12*200Ah Vision batteries. Still playing around with the settings 29-low DC cut off voltage. Is this the voltage where the inverter will shut down completely when ESKOM power is off and the PV array is not able to charge the batteries ? Gerrit
