Memory wear-out question

[MarkJ]

Hi,

I have an EV, and I use a Victron energy meter to detect whether the vehicle is charging. When the EV is charging, I do not want the charging load to be supplied entirely by my batteries.

I use Node-RED, and the Victron energy meter provides the charging power in watts. Based on this value, I can determine the EV’s current charging consumption.

My question is: If I repeatedly adjust the ESS Grid Setpoint from Node-RED based on the EV’s charging power (multiple times during a charging session as the charging power changes), will this have any impact on the system’s memory? More specifically, could frequent setpoint changes cause excessive memory writes and potentially contribute to memory wear over time?

Yes it contributes to wear over time, but:

• changed settings are not always persisted immediately, they live in memory until the xml is written to the flash.
• EV charging is a few hours per week.

I would not worry about that all too much.
