    Multiple charge controllers on a single battery 'fight' each other.

    I agree with the NQR. Epever does not give me very good support online. The tech usually just gives me a one liner about some other peripheral he thinks I need with no explanation of how to implement it... I have just ordered some Victron controllers that will hopefully solve the problem...

    Multiple charge controllers on a single battery 'fight' each other.

    Please keep us in the loop on how this goes. It sounds like something others of us could use?

    Multiple charge controllers on a single battery 'fight' each other.

    Interesting. Another option for me is to use natural shade to extend the total available charging time. My off grid system is at a cabin in the woods and the clearing in front of it offers numerous options for spacing solar panel arrays to take advantage of doing just that. I have mapped the...

    This is a tiny 5 position busbar rated for up to 12 awg and 20 amps

    Wago wire connectors available from two to five wire ports from almost any electrical supplier, also on Ebay and Amazon... I use them all over my solar systems with great results...

    Multiple charge controllers on a single battery 'fight' each other.

    I experienced MPPT charge controller fighting each other the first time I connected two EPEVER 2210 AN to the same battery bank. I started them separately with the circuit breakers to the battery and then added the PV circuit breakers. They started out sharing the load, but in the first five...

    I wish someone would review my temporary solution design while I wait for my Panasonic Panels to arrive so I can do it correctly...

    Much thanks for everyone's help, guidance and assistance. I just ordered another 48 volt MPPT Charge controller (150 volt and 40 amps) to match the one I have. It is the safest solution even on a temporary basis and gives me the option to add or change panels going forward. Have a Great Day!

    I will then ask you the same question I just posted... I was hesitant to connect the two different banks of 100 watt panels in series-parallel together because I had read they would interact strangely unless they were separated by using two charge controllers. Do you think these panels are...

    I was hesitant to connect the two different banks of 100 watt panels in series-parallel together because I had read they would interact strangely unless they were separated by using two charge controllers. Do you think these panels are close enough to combine in two series/parallel strings? The...

    Oh I totally agree, the system in the diagram was my idea for a "make do" alternative until the correct panels arrived. I appreciate all of your comments about why it will not work. All of my experience thus far has been with 12 volt systems with separate panel arrays and charge controllers...

    Ah so the worst culprit would be the negative ground from the charge controller in the middle of the battery bank. That makes sense. Are these inverters capable of being rewired internally to operate at 24 volts?

    The 48 volt MPPT charge controller has 150 volt max input voltage and the 48 volt PWM charge controller has a max input voltage of 100 volts. I read that there would be a potential conflict with using the two different types charge controllers on the same battery bank. It looks like my best...

    I wish someone would review my temporary solution design while I wait for my Panasonic Panels to arrive so I can do it correctly...

    The controllers in the drawing are also only 12/24volts that I use on my 12 volt system. I have one 48volt mppt controller and one 48volt pwm controller but I did not want to mix the two types? I really appreciate the input, sorry for the lack of information...

    Your comment with regard to the 24 volt split charge of the 48 volt system is exactly what I was worried about. I am scratching my head trying to figure out how they could interact improperly. Please advise what you mean when you say it will not end well? The plan is to have identical charge...

    I would appreciate anyone poking holes in the attached design while I wait for the correct panels to arrive that have been delayed... I have all of the components except for those so this is a make do... My training and experience says it will work fine, but I always like to have other eyes...
