Battery tender along w solar.??

I have one lithium battery and one 210 watt solar.. obviously when it's cloudy the solar does no good when I have my RV sitting at home. Can I also use a battery tender along w my solar to keep my battery up when hauler is sitting at home?

    Do you have a solar controller? That is your shut off.

    So what's the difference if the solar is working and you're plugged in to shore power and the converter is on? NONE, don't worry.

    I have my plugged in the house, AKA shore power all the time when not in use. You said ~ .I believe my solar is constantly charging..not sure on shut off..but it's a 210 watt panel . You'll need to figure that part out.

    Ummm solar and a battery tender it would depending on how many amps are driving the soler panel and does it have a shut off. Your tender has a build in one. otherwise you'll fry your lithium battery

    Multiple charging sources are not an issue. By all means plug it in and leave the solar connected.

    Lithium? Just disconnect. No need to float.

    Or do you have systems in the RV that must run?

    So at home u have your tt plugged in using your 30 or 50 amp service n adaptor to your house wall plug? Or do u use a battery tender? Yeah I was not sure if having both the tender n solar would conflict
