MPPT 100/20 Bluetooth connection problem

Hello Community!

I recently bought an MPPT 100/20 from Victron and it has been in use now for 3 months.

I had 5 freezes so far. The Bluetooth connection is not establishing, the app freezes at 20% connecting. After a while, all 3 leds of the device blink together 8 times and go normal (indicating charge state) again. The app recommends me to unpair the device, I did but nothing changes. I don't get the pairing popup even. When i unpower the device from pv and bat terminals and power again, I get the pairing popup and everything gets normal again for some time. I also tried rebooting my phone WO success when connection isn't happening.

On one freeze the device dropped the load with a fully charged battery (!). This is an absolute critical error because many times this devices are installed in unaccessible places and such a fault just isn't tollerable.

I'm on Huawei P9 plus with Android 7

Thank you for your reply.. I'll keep reading if any more info is needed.

Best regards!

I chose to buy the original Victron mppt knowing there is a similar Chinese product for half of the price. It is disappointing to wait 5d for a forum answer and not get a support@Victron email in case i need help. Customer service is defently not the reason that justifies the price difference

I have exactly the same problem with my 2018 MPPT 100/30 smart solar charger. I use iPhoneX. When rebooting the charger, everything works fine for some time, then connection freezes at 20%. Same happens using other iphone. Any suggestions?

Hi hase. Don't be too hard on the forum'ers. It's perhaps safe to assume by now that your difficulty hasn't been experienced commonly. At least with that combo of kit..

I'd suggest you borrow another phone and take another look through here: https://www.victronenergy.com/live/victronconnect:start

Note the section on connectivity issues. Your phone may never have been tested, so nobody knows..

You bought good cutting-edge kit, not cheap Chinee. Good decision, despite your issue. Perhaps you're pioneering? Sure Victron comms can be challenging to the uninitiated, but worth persevering with.

Have a fiddle with a tested phone..

Thanks John,

I agree, definitely the first thing to check is with another well tested phone.

Troubleshooting issues on the THOUSANDS of variants of android devices is a never-ending story. Thankfully it seems to be improving over time.

We rarely see any issues with iPhones, but most Android users do not like to hear that as a suggested solution :)


Sorry that this was overlooked, you initially "Answered" your own question. Which made it no longer show up on our "Unanswered" questions list. I will now convert your initial answers to comments and just leave the answers in place.

Thank you very much for your reply.

Defently an iPhone is not an option for me.

As the problem disappears when i reboot the mppt, I'd not search the problem in the phone. If i can get a support email, I can make Bluetooth captures and send them to you when the freeze happens.

Oneplus one fron my wife behaves exacly the same.

What exactly is happening/is expected to happen in the connection stage when the app says 20% connecting?
