I recently purchased a factory refurbished RS2000. I was hoping to replace my hodgepodge of inverters, battery chargers, and power strips that I use in the Sprinter, with one box. But it was immediately apparent that this RS2000 was not light on the house battery current.
I put it on my workbench and hooked an ammeter to the battery. I found a 5A load on the battery with the inverter on but no AC load. The "load sense" current is much better at around 1A with no load, but still much greater than my small inverter. Load sense is not reliably keeping a 75W bulb lit when load sense is set to 40W, and when the bulb is on, the inverter reports 110W AC power consumption. Operating just a laptop is out of the question without disabling load sense (and paying the 5A penalty), at least on this particular RS2000. As soon as I add a load that load sense can deal with, the additional current overhead of this RS2000 kicks in again.
Is this typical of high power capacity inverters like the RS or ProSine series, or unique to this RS2000?
Separately, I also found that at one point during the float charge, current was reported by the System Control Panel to be rising and falling between 0.7 and 2.2A over a period of about a minute, when in fact the ammeter showed it around 3A the whole time. I also found that the load sense current (no load) was reported to be 6 - 8A by the control panel when the actual current was just under 1A (possibly a decimal point error in the current measurement or reporting software.) Are other RS2000 owners also getting erroneous current readings? (I have a ticket in to Xantrex but wanted to know what other owners have to say about this first.)
