Replacing my solar controller ...help would be appreciated!
Iím replacing my solar controller because my current oneís display broke. Iíve disconnected the panels but Iím checking to see if I also need to disconnect the battery to install the new controller. Part of me sees no reason to disconnect the battery because either way the power will be brought to the controller in steps (positive lead and then Negative lead). Iíd have no problem disconnecting the battery but itís a real pain to get to (have to crawl under the van, put a jack underneath the tray, unbolt the tray, drop the battery, etc). Just trying to avoid an unnecessary pain. Ha!
Any help would be appreciated.
Also, Iíd know that I should only connect the panels if the battery is installed and connected.
