<p>There will be troubleshooting with this design. Probably easier to use it up and redesign. If my name was on the inheritance,</p>
<p>I would do it now or at the minimum fuse the strings. </p>

Remember all the parallel strings take offs must be the same size/length, otherwise you are going to exacerbate imbalance issues. <br />

<div dir="auto"> Its a good idea to think of batteries the same way you do PV Modules. Any time you have more then two strings they get individual fuse protection, this is also good for diagnoses purpuses too.</div>
