@dmajwool I’m advised that in my case, I can’t use a negative value since my grid company doesn’t allow export at all. They don’t penalize me or even monitor for any exports. A little feed in is fine by me but I’m not sure what it does to a worker maintaining the grid. For the sake of the workers and to maintain the integrity of the grid, I want to now run off-grid as much as feasible.
I don’t think that danger to the linesmen would arise : the feed-in would stop as soon as the grid connection was cut.
Nothing. Anti-Islanding safety is given by the grid code in combination with an MP2/Quattro2 (or by using an external inti-islanding relay in case of MP1/Quattro1), not by the power you are regularly feeding back.
That’s reassuring.
Under the grid code, each system has LOM detection enabled - this is a requirement for certification.
The older units and most quattros only have a single input relay, so technically one could fail closed and be a safety risk, hence the need for an external contactor with dual relays.
The MP2’s and Q2’s etc all have dual input relays so that cannot happen.
The multiple clicks you hear on grid recovery is all the relay testing happening. The system will fail to offline if any relay fails.
I’m using some sort of external relay though I don’t trust it fully. I plan to replace ít with the recommended one later. It’s not locally available. I had to make a special order to import it.
