Stupid Idea? Battery Tender to Power MPPT
I installed a Victron 20 amp MPPT solar controller over the summer. I added an SAE connector port to the outside of the van. I have a Battery Tender Plus 1.25 amp and Battery Tender 3 amp chargers. The both have the same SAE connector. I am wondering if I could plug either of these Battery Tenders into the solar port to supply voltage to the MPPT so that it can smart charge the my house battery? Would that even work or is it a dumb idea?
The van has the stock SMB Progessive Dynamics converter with the 4 stage Charge Wizard which I don't think is the best charge controller and I know it doesn't have temp compensation. I would like to use the new MPPT to maintain the battery while the van is in our shop for the winter. Plugging in the PV panels is not really an option because winters here in the Pacific NW doesn't have any sun for a good 5 months.
What do you all think?
