Off grid site. Customer wanted a bit of background power to maintain the system voltage in winter. Sporadic windy location. BYD lithum battery system. MPPT, Multi 8000, CCGx
We have attempted to use a small 300w 48v turbine that is suplied with a Morningstar PWM charge controller - but this is ineffective, due to the generally higher maintained voltage of the BYD's - The turbine rarely if ever touches a voltage above the BYD... so charging doesnt occur.
I am considering using the Orion-Tr DC-DC 48/48 Converter - as an interface between the BYDs - and a small lead acid battery setup off the Morningstar. The lead acids would buffer output from the turbine, and keep this operating in its voltage sweet spot.
Setting the Orion output at circa 54v say....
One thing i am not sure about (the manual is a bit scant to say the least !) is any low voltage disconnect capability with the Orion. The Morningstar charge conttroller dosnt appear to have any sort of output control to switch a remote load (like the Victron MPPTs do)
Thoughts on pitfalls for this idea?
Thanks
Chris
