Davydd - what is the DC voltage in your system at say in the middle of the day now?

Davydd's batteries are never stored. The system has been in use basically since day 1. I'd go with what Elite and ARV says for that.

The point was that relying on a generator autostart to prevent a system shutdown wouldn't always be doable.

The system still needs to be able to function without that feature.

What LVC is RT setting for their modules?

If 2.5V per cell then that's 10V. If 2.8V per cell then that's 11.2V. The AGM bank will be involved in powering the load way before those voltages.
