Last post by Starthex - Today at 12:40:49 AM

Коли тобі перевірити, до якої години курсують трамваї в різних населених пунктах України — знайшов сайт, де це все зібрано в одному місці.
 
t-v.te.ua — це транспортний довідник з дійсними графіками руху на 2026 рік. Тут є дані по таких містах:
 
- Дніпро (Дніпропетровськ) — електротранспорт й маршрутки.
- Харків (Харківська обл.) — тролейбуси, вагони, мікроавтобуси (з розбивкою по районах).
- Суми — тролейбуси, трамваї, автобуси (з нюансами).
- Чернігів — електротранспорт, маршрутки.
 
Користуватися просто: обираєте населений пункт і вид транспорту. Ніякої сторонньої води — лише розклад. Оновлені розклади на 2026 рік.

I don't have it in front of me now but I think I remember there is a separate reset for mngp2 somewhere in the mngp2 menus.

Thanks for the post Larry,

I've factory reset both Rosie and the Barcelona, how do I factory reset the mngp2? I can't find a manual for it.

Thanks for the help, much appreciated..

You should probably also do a factory reset for both the mngp2 and the barcelona in case you havent done that. Some updates need to start fresh for the new features to work properly.

The "Classic" charge controller / Re: Local App/ Classic monitor...

I use ones like these that I got in pack of ten on aliexpress or ebay.
https://www.adafruit.com/product/381
Basically they are the DS18B20 in a metal end, and they each have their own address so you can put them in a string and know which ones are which.
The Tasmota firmware makes it super easy to do this on one pin if you want.
I think you can do the same with ESP Home but havent tried that yet.
If you flash the Tasmota to an Esp32 ( or esp8266 ) you will see on the pins configuration drop down list option for these one wire sensors.

You can also use them with arduino too.

And with the MNGP2 on the Inverter page, I have probably 4000W of devices on and it's showing an output 929W

I updated the MNGP2, Barcelona and Rosie all yesterday evening Jan 31 2026

Scrap this, a breaker had tripped.

and, another thing to note:

my display is reading:


Battery 54.5V   3173.1
 MPPT 1        MPPT 2
344.0V        450.6V
 58.1A         0.0A
 3167W           0W
 0.9 kWh      0.1 kWh
Bulk.       Resting

Why resting?

Thanks again,
Jim

Barcelona / Latest software issues - Beta ...

Last post by Groton Vermont - February 01, 2026, 11:28:19 AM

Hi, I just updated my Barcelona to the latest release.

2 things I have noticed:

1. The system status is reading "Battery 54.2V.  -3093A"
The A is actually the watts I think?

2. Barcelona's output seems to be seriously reduced. The battery is at 80%, we are still BULK charging and yet I am seeing about a 6th of the output from the panels than I should be seeing.

Any ideas?

Jim
