Daily load output outage after update of SmartSolar 100/20 to firmware v1.53

After updating the firmware of my SmartSolar MPPT 100|20 (0xA05F) from v1.50 to v1.53 I have the following issue with the solar charge controller: every 24 hours at around 17:30 the load output automatically turns off for a short moment, leading to a sudden power outage for my off-grid system's loads (LTE router etc).

I don't know if the charge controller just performs a restart, or if only the load output is toggled. This never happened with former firmware versions.

Other than the firmware update nothing was changed on the setup at that time. BTW, the update was performed on 25.10.2020 at 15:47, and on the very same day at 17:35 the first load output outage happened. And from then on every 24 hours, every day.

There are no loads with high inrush current connected, the actual load is well below 1A at that time, no load is switch.

And it seems that I'm not the only one with this issue (see another Google Play review on 28.10.2020).

Thanks
Heiko

Yes, I am having a similar issue! My MPPT turns load off briefly every day in the evening and then turns off briefly again in the morning. I notice it because our appliances are programmed to turn "on" after a power reset and I find them turned on every morning and every evening.

Furthermore, the MPPT in lower-voltage scenarios around 11.5V (but above the minimum voltage set at 11.1V) suddenly starts turning load on and off repeatedly every few seconds. I posted that separately here: https://community.victronenergy.com/questions/65832/mppt-10020-turning-load-onoff-every-second.html

Hmmm .... since 1.53 my 150/35 is not working probably anymore. PV Power drops to nearly zero. (see screenshot). Updated to 1.54 yesterday. Problem persists. Where can i find the old 1.50 firmware (looked in victron professional already).

Thx

Jens

Thank you very much for your help on this issue. I downloaded the Mac version but it says the app is from unknown developer so it won't let me proceed to install the updated app.

Hi @tomvacek

That's because apple takes a while to approve the new version, please wait for that or update through VRM

@tomvacek,

if you trust Victron, then there is a way to open the new app anyway.

Here you can read how it'd done: https://support.apple.com/en-gb/guide/mac-help/mh40616/mac

Same issue here but not 24h mine resgtarted 19:25 and 05:20

I only wanted read my battery settings from the 100/15 and I had to upgrade to V 1.53.

PLEASE don't force the user to upgrade. It's really a stupid microsoft technique!!!

Why a user must upgrade to read his parameters.

Not even downgrade possibility. I have a tower with communication which cuts off now every X hours. That's very bad!!
