I just installed a new MultiPlus 3000VA 12-Volt recently, which is used with LiFePO4 batteries. I used lynx distributor as well. Yesterday the battery low light is on and I measure the system voltage is ~11v without any load. After I removed MultiPlus from lynx distributor, the system voltage is back to ~13v.
It will drop to ~11v if I connect MultiPlus again and even MultiPlus is in off state. Does it mean the MultiPlus is defective?
