Victron Terminology

Where can I find what the various terms mean utilized on the Victron App? The manual is of no help and I am unable to find what I’m hoping to find on their website. Thanks!

    Thanks. It is helpful. In a partially cloudy site canted away from the direct rays of the sun, I’m reading  from 4-6 watts. This seems low to me. Thoughts anyone.

    Do you have the factory solar?

    Yes. Appears to be functioning properly.

    Your battery voltage is showing you it is charging, with the 13.32 V (voltage) number.
    The "state" is showing as "Bulk", which is one of the three stages of charging a battery.
    So, without knowing what you are running inside the trailer, the good news is whatever solar you are getting is charging your battery.
    This battery FAQ has a description of the different stages of charging.

    I love my Victron stuff, but they would make billions if they would stop pretending that everyone is a nuclear power plant engineer and write some FAQ's in plain English.

    Well stated. Quantum mechanics might be easier.

    nuclear engineer / rocket scientist / embedded defense systems engineer here.  but almost flunked my quantum coursework back in the day.  your image showed bulk phase and 19W, but if at the time you saw 4-6W if your battery was close to fully charged, the victron may just show a few watts and "float" even with a perfect solar angle.  perfectly normal. 

    but power on an inverter and a toaster, and within a few seconds the victron should switch to "bulk" and show the max solar watts it can pull from the panel(s).

    on the other hand, i've had some solar panels that worked amazingly well before sunrise, and others where the sun has to be pretty dang exactly dead on to even get half of the rated panel wattage. if there's (1) not direct cloud obstruction, (2) the sun is within 45 degrees of straight at the panel, (3) the toaster is running, (4) voltage is down to 12.5V or lower, and (5) still you're seeing "bulk" and (6) only 4W... then it sounds like the panel has had better days, might be a design that only works in a very narrow set of conditions, or there's another problem in the broader system.
