Hello,
I have a 12 volt system aboard a Narrowboat with a Victron Multiplus 12/3000/120 inverter charger. I am using a bank of four 115 Ah Lead Acid batteries wired in paralell with three 320 watt solar panels and a Victron 150/85 MPPT controller. I have a Victron Venus GX to connect all the units and log to VRM.
I want to set the DC Input low shutdown on the inverter to around 12.4 volts but this means the DC input low restart value is a whole 1 volt higher at 13.4 volts due to the limitations of the VE configure software.
My only source of power into the boat is through solar so this can take half a day to reach. In reality I would like the restart to happen at maybe half a volt higher than shutdown at around 13 volts. This would allow for any bounce of the voltage once the shutdown happens, the batteries usually come back up by about 0.1-0.15 volts but no more.
I understand the reasons for the 1 volt difference to counter for the bounce in values but after searching the forums and finding this post https://community.victronenergy.com/questions/1366/feature-request-allow-dc-input-low-restart-voltage.html and in particular this section
"Hi all, last Thursday we released the update of VEConfigure allowing a 0.25V hysteresis (for 12V, its 0.5 for 24V and 1 for 48V) between the DC input low shutdown setting and the DC input low restart level. See above for details. "
I thought this would mean the limit had been reduced but on VE Configure version 90.04.226 its still 1 volt.
Can anyone help please, am I being totally dim, or is there anyway to reduce the 1 volt limit between DC Input Low Shutdown and DC Input Low Restart
Thanks in advance
