I would like to use an MPPT 100/20 primarily as a data logger to test the peformance of a new type of panel. I want it to track the maximum power of a single 300W panel and to record the power output of the panel as a function of time. My question is can I just connect a resistive load to the Battery output of the MPPT to dump the energy? I have a resistor bank which can dissipate 300W. I have tried this with some success and the MPPT is in bulk mode for most of the time. It stops periodically and all 3 lights flash (which is not one of the cases explained in the manual). I am wondering is the MPPT searching for a minimum voltage on the battery output? A key thing is that I want the MPPT to remain in bulk charge mode, as if it goes to absorption or float it will artificially reduce the output of the panel. Anyhone ever try something like this?
