Thank you Remundo for your lighting... In fact, I should have thought of it on my own... :?

@Yves: indeed, there are various security systems on my thermal system:

- 1 safety valve on the primary (pressure)
- 1 expansion vessel
- 1 safety valve on the tank (pressure + T°)
- and in addition, I usually partially cover the sensor from April / May to October ...

We may only be in February, but given the sunshine in recent days, well it's getting really hot...

Now, maybe I'm a little too "light" when it comes to maintaining the system? What is the lifespan of the safety elements such as the vase and the valves??

On my boiler stove, I have a safety valve, which empties a little water, but which also puts cold water back into the circuit.

You must have glycol, I think, but that can be done too.

Yes, indeed, it is glycol ... in normal mode, the valve lets it pass if over-pressure. But there is no feedback. Afterwards, you have to purge to avoid "water hammer" ...

With a small (big) modification to your installation, you can continue to use your current inverters on a backup network.
On the output of some hybrid inverters or converters (like Victron Multiplus) you can connect a "normal" solar inverter which will therefore continue to produce on your isolated site as if it were on the network. There are certain rules to follow, and depending on the brand it can be more or less complicated to configure.

I have also seen that some hybrid inverters (like the Fronius Primo GEN24 Plus) are able to provide emergency power without a battery (within the limit of what the panels can provide of course)
