Hi to all!
I have a multiplus 12/3000/120-50 on my sailing yacht and what I would like to do is that the hot water boiler (800W / 230V) shall be powered in case I have plenty of sustainable energy available.
In detail the hot water boiler shall be powered on in case all of the following conditions are true at the same time:
- no power from shore power connection (to avoid unnecessary energy costs)
- battery capacity is >99% (BMV 712)
- voltage is >13,3V (indication that should be energy available from solar or wind generator / to be discussed)
Is there a change to program one of multiplus relais accordingly?
Best would be that the hot water boiler would be powered for 15 minutes and then the above mentioned conditions should be checked again (in a permanent loop).
My today´s setting:
- Multiplus 12/3000/120-50
- Bluetooth Smart dongle (at multiplus RJ45 VE.Bus Port)
- 4x100Ah AGM parallel at 12V with Victron battery sense (to be replaced by LifePO4 in future)
- 900W of solar energy (at Victron MPPT 50/100 12V)
- wind generator (Silentwind Pro 12V) with 12V MPPT hyrid battery charger
- 500A Victron shunt connected to BMV 712
- MK3 USB and Victron Ve.Direct USB connected to my notebook running Victron Connect
- hot water boiler 800W/230V Sigmar Marine „Compact“ SM20 with thermostat
I do not find a good documentation of the relay´s of the multiplus and possible individual programming and therefore your assistance would be highly appreciated!
Many thanks in advance!
