Remote Switch Panel for Spartan Power IC Series Inverter Chargers

This is an exceptional display for an exceptional inverter. It is larger than I was expecting (based on other manufacturer's remote displays), but it is ruggedly built and give a full spectrum of data and control.

The Remote Switch Panel work as expected during the first three months, even thought the cable broke when installing (i replace it with a shorter cable), the panel show all the data comparable with meters used to confirm readings.The last days, the load always display 1%, the voltages and status are ok, but the load never changed from 1% neither with power loads on.

I bought this without being able to find a lot of information about it, but being as it's the only one compatible with my inverter it wasn't a hard decision. I primarily got it to use as a remote switch, and it's useful for that. The information provided on the screen though seems to be largely for entertainment value only, and is missing what I would consider important information. It doesn't give any true load readings, only a vague load percentage that doesn't seem to really mean much. I put a 2A test load (PF 1.0) on the inverter and it reported 0% load for a good minute after the load was applied, then jumped to 3% and stayed there until I removed the load. It does not give indication of status beyond inverting or bypass - no charge cycle information. Battery voltage is vastly different than what's measured at the inverter DC terminals with my Fluke meter. The sole button on the display appears to turn on the backlight. I wasn't expecting a lot, and bought this mostly for use as a remote switch and it does do that. Barely.
