Finally got friends Multiplus connected to his new Lithium batteries which he fully charged first . re programmed the 150/75 MPPT to Lithium pre-set but the smaller 100/50 MPPT had slightly different menu option for pre sets but it wouldn't accept it , i selected pre sets and then clicked on the Lifepo4 an when i exited it went back to User Defined , no matter how many times i tried it jt wouldn't accept it , everything else was greyed out so there wasn't anything else to press to save it , ended up using the User Defines and setting it Manualy
Next was the Multiplus , for some reason when the generator was started the multiplus would was passing through the current but would not go into Charger mode , clicked every so often but didn't latch on , noticed when something in the house was turned on it would change to charge for a sort time , that seemed to be the pattern , the batteries were 100% but i expected it to have remained on Charge but in Float mode .
Am i missing something simple in both cases .
