Using photovoltaics for home electricity without synchronization requirements of the electric grid

Hello,
which technical requirements do we lack to use our self-produced photovoltaic electricity in the house without a battery storage and without the clock generator (kHz) from the electricity provider? We would like to be autonomous.
For clarification: We use our home-generated electricity when it is bright, but we always need the functioning connection to the existing house power from the utility for the clock signal. (I hope I understood our photovoltaic technician correctly, unfortunately he is no longer reachable.)
Thanks for the feedback

I don't quite understand the problem here. If you generate and consume electricity during the day, then you are not taking any power from the grid. And obviously you need a (permanent) connection anyway since you have no storage capacity and would also like to consume electricity at night.

What is the purpose of the question?

Hello,
which technical requirements are we missing to use the electricity we produce via photovoltaics in the house without a storage battery and without the clock generator (kHZ) from the electricity provider? We would like to be self-sufficient.

This is only possible with the appropriate inverter and a storage system. Additionally, you have to hope that enough electricity is produced in winter. However, it works with a really large system and sufficiently large storage.

What do you have on the roof? 50 kW peak? What do you envision as storage to last, for example, more than 3 weeks of winter without sun? Is a diesel generator available as a last resort?

Finally, the question to you: What do you really want to achieve?

Hmm, I don’t know how to respond to the respondents individually. So here, with thanks to everyone who replied: We have a 50 KW peak system on the roof, the system builder told us that if power flows from above, we can use it directly without! a power storage system; we just need the timing signal from the grid. The inverter would handle this automatically. Therefore, all devices in our home are only operated during the day. But what if this timing signal is not given because of a power outage? Then we have power on the roof but no way to use it. Hence the question: how can we imitate this timing signal so that power can continue to be used directly? We will of course not draw much power, so neither washing machine nor dishwasher. Our goal is that during a grid outage 1. the aquarium continues to run (power demand 150 W/h), 2. the heating element of the buffer tank produces hot water for 3 hours a day at the lowest level (1Kw/h). We do not expect to be without the grid for several days but want not to do without power for 30 hours. Maybe it’s too much panic, but when you already have power from the roof...

Timing signal is nicely put. Let's say your system is then connected to the grid.

But what happens if this timing signal is not given, due to a power outage? Then we have power on the roof without the possibility to use it.

That depends on the inverter. There are devices that then separate you from the grid (otherwise you damage the grid if you keep feeding in power and push electricity onto lines that might currently be repaired by people – simplified). Just adjust a bit of the electrical setup and that’s it. So just buy a suitable inverter. Your solar installer can help with that.

Our goal is that in case of a power outage 1. the aquarium continues running (power consumption 150 W/h), 2. that the heating element of the buffer tank produces warm water on the lowest level (1Kw/h) for 3 hours a day. We do not expect to be without the e-grid for several days, but want not to forego electricity for 30 hours. Maybe it’s too much panic, but if you already have power from the roof....

At least with such a huge system you always have enough power. But there are few consumers in such a huge house (or farm, where the whole barn is covered with photovoltaics). And what do you do at night? If you shower in the evening, the warm water is gone. At night the aquarium also has no power. Etc. An example inverter: a Fronius Symo Gen24. But I have no idea how your system is currently set up – type and number of inverters. If it’s financially irrelevant to you, then upgrade. At least it should remain below five figures. What I personally think of it? Total nonsense.

Hm, I don't know how to reply to responders individually. Therefore, here with thanks to everyone who responded: We have a 50 KW peak system on the roof, the builder of the system told us that when power flows from the grid, we can use it directly without! a power storage system, we only need the timing signal from the grid. The inverter would do this automatically. ...

a 50KWp system on the roof and no info about island operation or similar? I don't believe that, sorry.

Therefore, all devices are only operated during the day at our place. ....

seriously? The solution for you would be "picea". But not just throwing out >100K without informing yourself - right ;)
