I understand the need for anti-islanding, how does your device continue to have a feature wherein I want to have the Solar to be able to (i) charge my solar batteries and; (ii) the excess pv power, if my batteries are full to be able to power my essential loads? Where can we get this device (outside of an inverter), that works, given the above requirements as I am based in Zimbabwe. Can I order online or in South Africa or do you have a local distributor? If we have dirty frequency from the grid, is there a way this anti-islanding device can be programmed for more tolerance variations e.g. +/-5%
how do they sense (input) when the output is the same as input (you sense your own output, and utility is down) (witch is fine (eg 50Hz 230V). In other words, how you distinguish Inverter frequency from Utility Frequency, after initial connection? (are there extra information cables coming from the grid? or other technique?)
@@DigitalBenny thank you, my question is how do they "listen" after synchronization. Eg. the utility goes down but the inverter is actually listening is it's own output. That would probably may need an inverter to stop outputing power (at least for short time of period) to listen.

The inverters "listen" to the grid frequency and match their output. No extra info is needed, it just copies the phase of the utility

@GiannisKaralis Yes, but the "short period of time" in which the inverter "listens" is milliseconds
Helpful ✅ thanks
