[RE-wrenches] Utilities see battery bank as parasitic load?

[Chris Daum]

Hello Wrenches:

 

Ok, here's one for you.  We have a customer whose utility provider is L.A.
Dept. of Water & Power; he's getting ready to install his battery-based
grid-tie system with a Radian inverter, load center, HUB4, eight - 250W
modules....etc.  But the inspector is calling foul, saying his 'battery bank
is a parasitic load"  --  the inspector also claims that the battery bank is
a "generator" so he must utilize a straight grid-tie inverter (5KW Power
One) and make this an AC coupled system to be legal. 

 

The question then becomes; does the PowerOne GT5kW inverter play nicely with
the Outback Radian when the Radian is the BB Inverter?  

 

Maybe there is a way to save our customer the cost of the new PowerOne
inverter if we configure the Radian differently?   

 

Any advice or suggestions that you can offer would be most helpful!   And is
anyone else running into this?  It just seems crazy. 

 

Best,

 

Chris Daum
