I have the Quattro 48/5000 charging lithium battery (Chevy volt module) My concern is I was reading that you can not charge these batteries when it is freezing. I will shut the system down in the winter months, but we do go there one weekend in the winter. When I turn the system on does the Quattro know not to charge the battery bank till the cabin heats up? I was seeing some system has that feature. I was thinking of just shutting the breaker at the panels to the cabin warms up, but if I forget I wanted to have a back up to protect the batteries if the Quattro doesn't offer that feature, Please let me know if it has it or if you have anything i could add to the system to protect in from charging in freezing conditions
