The output is off when battery is 11.00V but when the voltage increases above 13.00V, the load mostly still remains off (which should not be).
Note: I have been waiting for more than 2 minutes to get the output results.
Also, the firmware is updated to latest which is x1.64.
The test wiring diagram is provided below
I tried also with the PV and load connected but this issue is occurring, but if I set the power supply voltage to 14V DC (With user def. algorithm 1, load switch high voltage level:13.00V), it will turn on the load output.
There are three of us reporting the same issue. Victron must have a bug in their product (hardware or software). Not sure how to raise it with them yet.
I pinged my supplier as Victron recommend and got zero reply from them.
Just to be sure, do you have the streetlight functionality off?
And what about VE.Smart networking?
Or do you still have the jumper somewhere on the VE.Direct port?
Asking because these are all things that might influence the behaviour of the load output.
Hi @thiemovanengelen,
The streetlight functionality is off, also smart networking is off.
Jumper is also removed.
As per the operational manual, the test is performed, but sometimes it will work sometimes not.
I have the same issue with user def. Algorithm 1. Any solution? I waited more than the 2 minutes for automatic switch on, and the only way to kick start it back on when it goes off is to set it to Always On then back tho user def. Algorithm 1 and it will stay on and turn off when the voltage goes below my configured threshold of 12v, but does not turn back on when battery voltage reaches 12.8 which should turn the load back on.
Hello, same issue here with MPPT 75/15. Algoritm 1 will desactivate the load output but will never activate it again (high treshold set at 11.5V, battery at 12,80V and load still desctivated)…
AT the very first time, my jumper was in place , but now removed and still the same behavior…
I was thinking that perhaps a short circuit detection on the load output me be the problem. This could be caused by a high capacitive load, causing a high inrush current. Can you also try without any load connected? Or perhaps there is a possibility to have the load output switch a relay that switches the actual load?
1 * choose remote on/off on RX (this will stop solar working)
2* set yourlow and high voltage
3* reset RX to Load output configuration
4* WAIT …i think its very clever as in just because your just over or under it must sense the AH somehow and deends on how big your loads and solar inout is
5 - can take upto 5 - 10 mins to work but it does work !

I have the same problem with my smartsolar 150/45 (optional display version) with fw v1.64.
I wish to use the programmable relay to switch in the load when battery volts exceed 14.6v and switch it off when below 13.6v.
I have configured this in load output settings and relay settings but it is not switching when it should. manual switching works, as does switching when in float.
Will there be a firmware update for these mppt’s?
v1.66 is only available for 75/15 models.
I got mine working by setting the switching points 0.4-0.5V below the desired settings.
This offset might be to do with it using the voltage measured by the MPPT rather than the one shared by CVCC. I’m just guessing that though.
