The SMA inverters are NOT isolated, so you will need a 100% isolated DC power source, and in addition, they are not made to work with a battery input. There is isolation detection, which will shutdown the inverter if there is any leakage to PE. Also, The MPPT boost converters are made to work only with PV inputs, with the high likelihood of you smoking it with that low of an impedance source.
