<p id="reply-intro"><span style="font-size: 12pt;">When I do this I tend to use an A or B switch for high voltage solar and then use a battery based with high voltage mppt or more commonly now on DIY, Costco, and Signature, an all in one battery/inverter/HV mppt. My clients mostly are technical and can comprehend. I am lucky to have them!</span></p>

<div>The panel wiring to automate can be expensive to do. Go manual! How many times and how long is it out??? And so if the client is up for it technically and wants to keep cash in pocket, the Florida hurricane tap is great. You can't do any of this with big systems and non technical people. However, if it was a long outage you are set and Offgrid and still have cash in your pocket.</div>

<div>Big systems always seem to have big issues to me.</div>
