Venus GX Overvoltage Repair

Hi. My Venus is totally dead. I suspect an over voltage as the battery stopped and the mppt voltage probably increased and supplied the Venus with more than 70V. Can it be repaired?. I have opened up but don't see any visible damage. Thanks

@Greg Walton, the MPPT will never output that high of a voltage - regardless of what PV voltage is coming into the MPPT, output voltage will be determined by your charge profile.

There are no user-serviceable parts in the Venus. Have you checked the fuse in its power supply? If you have, and you have absolutely verified that it is good, please contact your dealer for additional troubleshooting steps and/or to inquire about warranty service, though be advised that by opening it you've definitely compromised its eligibility for warranty coverage... that'll be a discussion between you and the dealer from whom you purchased it, however.

Best of fortune!

Thanks Justin. However in my silliness I replaced the power cable supplied with the Venus with a longer cable as needed to. Unfortunately thereby removing the protection fuse. It is now on the new one! There are no physical damages to the unit, I was hoping to see a blown cap or something which I could replace but nothing at all obvious.

Thanks for your reply.

Hi Ewald, there are no physical damages to the board, so nothing really to show. Thanks for your reply.
