Have not the standalone solutions been superseded by the more integrated solutions from vendors such as SMA? I've no real idea what they are doing in the 3P market, but for general 1P installations, they offer the option of a monitoring device that varies the output of the inverter depending on the monitored export. Such a configuration would allow the addition of additional AC based generation devices such as an always on CHP device as the inverter(s) output would just be lowered more if there was no internal demand for the excess energy.

At the point storage is added to such a configuration I guess you will be limited to the same vendor (SMA in this example), otherwise you could end up with the different export monitoring solutions causing feedback loops in the devices they control.



Yep, that would be my preferred route, a sunny tripower inverter and the new sunny storage  (AC coupled).

   Hi Wesite,
           That is a possible as I have the space it seems the thing to do. Plus I'll have to sort out the bioler.

           It appears that there was a wood stove with a backbioler that was ripped out years ago pipes capped and hidden so the hot   water is probally thermo  syphoning out of the hot water tank ......
 

                                                  cheers
