Setting Analog Inputs - SMA FUEL SAVE CONTROLLER 2.0 Instrucciones De Uso

SMA Solar Technology AG
Destruction of gensets due to insufficient reserve power
Once the SMA Fuel Save Controller and PV power plant have stopped, the PV power plant is no longer available as
energy supplier. Now only the gensets supply the loads. If the current reserve power of the gensets is insufficient for
supplying the power required by the loads, the gensets become overloaded Sustained overload of the gensets can
result in failure of the power supply and destruction of the gensets.
• Check whether the current reserve power of the gensets is sufficient for supplying the power required by the
loads.
• If the current reserve power of the gensets is insufficient, switch off the loads or connect additional gensets. This
increases the reserve power of the gensets.
• If sufficient reserve power of the gensets cannot be ensured in operation, do not use the switch input DI 7 of the
Fuel Save Controller (Fast Stop contact of the PV power plant).
