Hi everyone, I’m looking for advice on how to configure the Victron MultiPlus 2 inverter. Specifically, I want to prioritize electricity consumption from the battery and solar panels. However, if the maximum power output of the inverter is reached, I’d like it to supplement the missing energy from the grid.
Has anyone successfully set up this kind of configuration? If so, could you share the steps or settings required to achieve this? Any guidance would be greatly appreciated!
Without ESS, only way, use ignore AC input and VS function. And it cant supplement missing power from grid, it drop full load to grid until power is below inverter limit. I use this setup for long time, no problem.
I have ESS installed, and for me, it is a priority that the inverter can supplement power from the grid when it reaches its maximum limit, rather than shifting the full load to the grid. This functionality is essential for my setup. Is there a way to achieve this with ESS enabled?
I found it! Just set the maximum inverter power on ESS and the grid input to 0 watts. When the inverter reaches its maximum power, it will start drawing from the grid to compensate.
Do you have an energy meter to measure the grid? This happen natively with ESS installed. It uses the battery and solar until low battery voltage shutoff or min SOC unless the grid fails.
This is very interesting. I’m in a van and don’t have ESS installed as I don’t think its relevant (might be wrong). The solution I’m looking for us to prioritise battery (inc inverter) until the battery reaches x%, and then enable shore power to charge and supply mains. But also with the ability to automatically “top up” when I go above the inverters wattage limits.
So just had a little play using a config file (for safety!). And forgive me as I’m relatively new to this!
ESS Set-up:
Battery system - They are 3rd party (TBEnergy) monitored with a SmartShunt. So would it be:
“System uses LifePo4 with other type BMS” ?? Or “VE Bus BMS” ??
Capacity 450Ah (3x150ah batteries)
Sustain Voltage 12.5v (unchanged)
Dynamic cut-off (unchanged).
Restart offset (unchanged).
PV Inverters - “No”. I only have solar through a couple of MPPT’s so I assume that is the right answer?
Questions I have:
How to I configure to stop using AC until it needs to due to low battery but also to “top up” over and above the Mutliplus wattage?
I’ve had to select a “Grid” but obviously I won’t be sending power back to the grid. I’ve currently just selected a random UK Grid. Do I need to change anything for this to operate correctly ?
