[RE-wrenches] Component Choices for MY RV - Apollo Solar?

Sat Dec 25 16:53:22 PST 2010

I have answered an eariler email, but in regards to backfeed, I have back feed up to 2kW of grid tied inverter into my Magnum 4024 AE and it held grid specification for the DGI inverter.  Above 2kW into the Magnum the Grid tied inverter kicks out on frequency specification.  Other inverters do the same for me, cause DGI kick out also at about the same level ie  about 50% of capacity.  Sorry I do not have many examples of this. but I do not have any contra indictating examples.
