December 1, 20214 yr Good day what causes the Mecer 5kVA/5kW to cut off solar midday. Is there a setting am missing. my option 1 is Sol. I want a situation whereby during the day we use solar for loads and to charge the battery and only use eskom at night or when solar is not enough. thanks. Inverter is detecting my Pv voltage = 89V.
December 2, 20214 yr Hi @LeeMun 89 volts would be OK for a low voltage inverter 145vdc but it would be too low for a high voltage inverter 450vdc. Please check the sticker on the side of your inverter to confirm which model you have.
December 2, 20214 yr My guess would be that your battery is full at time that time. If it discharges the battery down to 95% then starts using solar again then it working as designed.
December 2, 20214 yr There is a bug in the axperts that seems to be related to going into float. Search for the dip and freeze posts here. When it happens the solar shuts down and doesn't always start up. Do you have any monitoring on your system such as ICC or Solar Assistant? Sadly if this is the case there is currently no watertight solution.
December 2, 20214 yr What type of batteries do you have? If they are lithium I would suggest changing to sbu and you can then cycle them, making better use of your investment and also reducing the chances of the freeze bug if this is what the problem is.
