Hi Hotswapster
To answer you question, simply trawling the web for as much info, also the other post I have commented on in this regards had a lot of info
I have been in contact with my local Solax installer and they could not tell me much
Solaxpower have also been a waste of time as they never respond to emails from their website contact form
Anyway, Would be very interested in knowing your setup. Seems like it is the answer to moving away from emoncms
