[RE-wrenches] Energy Storage and Working Spaces for Other Equipment

[Jerry Shafer]

Well with the BPE 16kWh cabinet is not an issue then when its u der a
Outback radian there is just enough room for a note pad. When we did the
industrial batteries l will say that would be awkward hence they were never
under the inverter mainly for the safety and gassing, blue planets dont gas.
