Besides what Tom says, it looks like your “sensor.modbus*” do not exist when the templates are evaluated.
Too few information for a fix.
What information is needed?
Whatever you think is relevant.
We don’t even enough info to tell you where to start. All we know is that a sensor.modbus_zcs_energia_generata_totale (and co.) is not existing when you try to evaluate a template somewhere.
Apparently, it is for availability ( for attribute '_attr_available' ), in which case you should check if sensor.modbus_zcs_energia_generata_totale is not null first.

What I can say is that this error only occurs when restarting the HA, after which the sensors seem to do their job.
These are the original sensors:

You likely already changed the template according to Tom’s recommendation.
I’m pretty convinced you won’t have the message at restart, now, but to be sure;
availability: "{{ states('sensor.modbus_zcs_energia_generata_totale') is not None and states('sensor.modbus_zcs_energia_generata_totale') | float(0) > states.input_number.filtro_produzione.state | float(0) }}"
It is probably because the secondary sensor is created before the main sensor…
The fault will resolve itself (apparently) when the main sensor loaded.
Solution as Koying said (or change the order of loading the sensors)
PS Good to hear you got it to work 
Yes I had made the change but when I restarted I always got the message.
I’ve now made your change and when I check configuration HA notify me this message.

Invalid config for [template]: invalid template (TemplateAssertionError: No test named 'None'.) for dictionary value @ data['sensor'][14]['availability']. Got "{{ states('sensor.modbus_zcs_energia_generata_totale') is not None and states('sensor.modbus_zcs_energia_generata_totale') | float(0) > states.input_number.filtro_produzione.state | float(0) }}". (See /config/packages/modbus.yaml, line 751).
No, in the modbus.yaml file the order of the sensors is correct. First the main sensors are created.
But they are different problems
Man, it’s literarily the first google result:
no test named ‘None’ · Issue #520 · pallets/jinja · GitHub
Use lowercase none (and please help yourself a bit).
Man don’t be angry please, I’m sorry, I’m newbie and I don’t know English well. I am very grateful for your help.
