    Sorry.
    Electronics is not an easy subject to grasp. The dummies book is pretty comprehensive. And then real life never matches the textbook examples. And when you do figure out a shopping list, the local shop does not carry that model, so you have to go to the internet and hope they don't ship a brick in a box.


    You can use your existing panels, but you have to put 2 in series for about 100V, and then use an expensive charge controller like I mentioned that has a 150V input.
    Or you can change the panels to either lower voltage in the 35V Voc range, and use 2 in series with your existing controller. Or select a panel in the 80V Voc range and use your existing controllers.
    Either way, more than 2 strings in parallel, requires a OCP device in a combiner box
