    I have set my Blue Solar controller to the parameters in this video, however my batteries don’t ever get charged up to 100%. It seems it tops out at 94/95% and then just floats to maintain that level until the sun goes down. Are these still the recommended settings?

      Thank you for your question. When looking over the settings in this video everything seems correct, however the time limit would vary depending on how many batteries you have. We recommend that the time limit is 30 minutes per battery. So, if you have 2 batteries the time limit would be 1 hour. If this problem persists please email us anytime at [email protected] and we can continue helping you from there.

    Based on your comment, should we decrease the time that is set in the charger- the video shows 6 hours if I can see it correctly, if we are running two batteries should we decrease that down to 1 hour?

    • Dianne F | Jul 11, 2018 at 8:39 am

      That is correct, if you have two batteries please decrease it to one hour. We recommend each battery should be at 30 minutes. If this problem persists please email us anytime at [email protected] and we can continue helping you from there. Thank you.

    Has anyone a list of settings that need to be changed.

    • Dianne F | Nov 16, 2018 at 3:08 pm

      Hello Mike,

      Are you referring to a list of settings that need to be changed on the blusesolar MPPT solar charge controller? If so, the settings are below.

      Battery preset user defined
      Absorption 14.4
      Float 13.6
      Absorption time put in thirty minutes per battery, so if you had 2 batteries it would be 1 hr.
      Equalization 14.4

    Looking at this video and comparing it to the “programming a Victron smart solar charge controller guide” post dated July 10th, I noticed the absorption voltage is different. This video recommends 14.4 while the other post recommends 14.6. Which one is it? If it is in fact 14.6, should I also change my Xantrex Freedom XC to 14.6 absorption as well? Please help

    • Dianne F | Nov 16, 2018 at 2:55 pm


      14.4 is perfect, that is the voltage the batteries will do their self-equalization. You can go up to 14.6, but nothing over. 14.4 is preferred.

      Thank you!

    I am trying to setup for the Victron MPPT 100/50 the version of the phone software does not have an option for Absorption time with out going into the “Expert mode”.

    Do I need to go into expert and adjust the absorption time? Is there anything else within that section that I should be tweaking?

    • Dianne F | Nov 4, 2019 at 8:24 pm


      Yes, you will need to make the battery preset “user defined” and select the expert mode. Weather you choose “adaptive” or “fixed” you will want to make the absorption time 20-30 minutes per battery. You will also want to make sure that the automatic equalization is disabled and the temperature compensation is also disabled.

      Thank you,

    Do you have to ground the MPPT 150/85 when wiring it?

    • Dianne F | Dec 3, 2019 at 8:39 pm

      Hello Glen,

      Grounding can take place for your solar system through a ground(negative)bus or directly to the case ground on the charge controller, either one is acceptable.

      Thank you,

    I am setting up my 100/50 and my app is nothing like whats shown in the video. I can change voltages but I can not turn off equalization voltage I can only lower it but only to 6 v. Is there and updated video to the new software app and settings ? I have 4 100Ah 12V LiFePO4 Deep Cycle Batteries and multi plus 3000 in 30 amp travel trailer. Thank You

      Hello Richard,

      Your 100/50 is most likely a “Smart Solar” and we have a different blog post for this device with some updated information, its called” Programming a Victron Smart Solar charge controller guide”. Even since this post, Victron has added some content and the settings can be reviewed below for some more advanced expert mode settings:
      Absorption: 14.4 to 14.6 volts
      Float: 13.5-13.6 volts
      Equalization: Off or 14.4 volts
      Re-bulk voltage offset: 0.20-0.40 volts
      Absorption Duration: adaptive
      Max absorption time: 20-30 minutes per 100ah battery
      Tail Current: 1.0A-4.0A
      Eaqualization Current Percentage: 0%
      Automatic equalization: Disabled
      Maximum Equalization Duration: 0m
      Temperature compensation: 0
      Low temp cutoff: disabled

      Feel free to give us a call at anytime if you would like us to walk you through setting this device up 775-622-3448.
