I'm trying to install 2 multiplus 12/2000/80 in 2 phase system to run my camper(50 amp plug). I've wired it up according to the guide. Ive measured several points and have consistent 13.2 v from battery all to the units. 1st one turns on fine, but both trip alarm when the 2nd unit is turned on. Even without the load it does the same. i have 2 12v 200ah dakota lithium batteries( tried both paralell and in series with same results) the solar panels are not connected, just the batteries so that i can test everything first. Any help would be appreciated
