Wildly fluctuating DC loads while running generator

Hello!

I have noticed that when I run my generator that the DC load shown on the remote console or the HTML5 app is fluctuating wildly. In the video below my real DC load is almost constant: internet router, Venus GX, and two LED strips.

Any ideas?

My guess is that it is the AC-in that is fluctuating and the DC load is calculated incorrectly.

Hi @osaether

See the manual:

quote:

Enable this for boats, vehicles and installations with DC loads and chargers - in addition to Multi and MPPT chargers. This won't be applicable to most off-grid installations; and any discrepancy between the DC current measured by the Multi, and by the BMV, will be attributed to a 'DC system'. This may be power-in from an alternator, or power-out from a pump, for example.

A positive value indicates consumption. A negative value indicates charging, for example by an alternator.

Note that the value shown will always be an approximation, and is affected by the variation in sample rate between elements of the system.
