Nowty Towers Vs UK Grid Storage

[Stinsy]

What with my elsewhere-documented inverter issues being resolutely unsolved, I’ve been looking at these…

How are they? Can you manage them remotely or is it a push-buttons-on-the-front kind of deal?

I bought the parts at Christmas with a view to building it and playing with an ME3000SP as an aux battery charger

My first one was doing the "normal mode" with the CT clamp until I upgraded to the higher power SMA sunny Island. When the sofar first came out I reckon they were the best budget battery inverter on the market.

They are mostly a "push-buttons-on-the-front kind of deal", but some folk into software can control them in fancy ways in "Passive Mode", I keep thinking about whether to learn more about that. I think there is a whole forum or some other website with loads of info on them somewhere about.

But for now I just use them as a 3kW on or off dumb aux battery charger / discharger (in "timed mode" which is really a "test" mode without any CT clamps) which I control with a WiFi socket tripping a high power contactor on the AC side. When the AC goes off they just sit there forever with a grid failure error until I re-connect the grid, then they count down 60 secs, then continue what they were doing.

EDIT - SimonSays in the last post has linked the website I was thinking of.
