Hi everyone,
I have a 21hp maize mill machine connected to three 8kVA Victron Quattro inverters and a 15kVA Fronius Symo inverter. I recently installed a grid connection and a grid smart meter (EM24). My battery storage consists of 600Ah lead-acid batteries, and I've set the minimum state of charge (SOC) to 70% unless the grid fails.
My issue is that when solar energy is low but the grid is available, the Quattros draw more than 60A from the batteries, which is bad for the battery health. I want to ensure that when there isn't enough solar power from the Fronius inverter, the Quattros only take a maximum of 60A from the battery, and the rest should come from the grid.
Here's what I've done so far:
- Enabled ESS mode in the VictronConnect app.
- Set the minimum SOC to 70%.
- Installed the EM24 smart meter at the grid connection p
- oint.
How can I configure the system to limit the battery discharge to 60A and draw the additional power needed from the grid? Any detailed steps or settings adjustments would be greatly appreciated!
