Reliability SOC VRM


we are using a MultiPlus-II VE-buss-ystem connected to a VRM. We also have several meters to measure the consumption.

We have noticed that the the SOC tends to be same irregardless of consumption above a certain threshold. For instance will a consumtion of 5kWh and 6.8kWh throughout the night both yield a SOC of 11% in the morning.

How reliable and accurate are the state of charge estimate (not a direct measurement from what I have heard)?

The built in measurement of the Multi is quite poor. External shunts are a necessity for ESS systems.
