Hi,
There is an idea to reduce self-consumption by a hybrid inverter, but I don’t know how to put it into practice.
I am planning a solar system, for 2 hybrid inverters of 5 kW each. Basically, they will perform the function of a UPS, since power failures are rare, and the function of selling excess energy to the network.
The unpleasant moment is that the idle consumption will be almost 2.5 kW per day (for both inverters).
A good solution, I think, would be to turn on the bypass mode at night, when the solar panels are still not working early. The power circuits would be in an economical sleep mode, the MPPT controller would not work at all, and the battery would be connected only in the event of a critical voltage drop. But, unfortunately, for some reason, the bypass mode in the inverter is activated only in case of overload, it cannot be forced to turn it on.
The question is: is there any circuitry for manual, or even better, automatic transfer of the inverter to bypass mode at night, without primitive two-way mechanical switches?
I would be grateful for feedback, or for some similar implemented ideas.
