Dear Powerforum member,
We noticed some unusual activity on the Powerforum towards the end of 2023, and had it investigated. Most of the activity was the usual “doorknob rattling” from automated spam and reconnaissance bots, but there was also evidence of a determined threat actor, who unsuccessfully tried to compromise members’ accounts. Even though the attack was unsuccessful, we took the opportunity to strengthen The Powerforum’s security, as well as the monitoring thereof.
These new monitoring measures have given us early warning of some unusual activity today, and after doing some random sampling, we have noticed that some of The Powerforum members’ email addresses were tied to publicly available breach data, where passwords were disclosed.
We value all of our members, and wish to protect our members against impersonation or any other nefarious activities. We therefore suggest that members consider doing two things:
1. Please visit https://haveibeenpwned.com and use the form to check whether any passwords associated with your email addresses have been compromised in past worldwide breaches. If so, please take action if the password may have been reused on The Powerforum or elsewhere, and change your password; and optional:
2. Enable Google 2 factor authentication, which is available as an option on your profile page. It’s quite easy and simple, and once enabled, will give you protection in the event of a password compromise.
In addition to the above, we have also taken a decision to request that all members, regardless of their status on haveibeenpwned.com change their Powerforum passwords by 25/03/2024.Kind regards
The Powerforum Team. -
Please Post In The Correct Section :)

Large 'Retro' Power System Display
HedgeSlammer posted a topic in Inventions,
Vital to being able to keep within the inverter output limits (and avoid importing expensive grid power unnecessarily) is having the means to display the relevant information in an immediate and accessible way.
That's what I told my wife, anyway. Really, I'd just scored a bunch of old RC servos on ebay for £5 and I wanted to play with them. 😉
In context:
It uses 6 servos, a Wemos d1 mini clone and a tri-colour LED. Dial faces are 3D printed, with a filament change from white to black (which turned out much better than I imagined, TBH).
The servos only had around 90° of sweep angle, so I 3D printed some little holder/gearbox things to get over 180° and provide a shaft for the needle to go on, plus some 'steampunk' needles.
All run buy the obligatory D1 mini and held together using the very latest in 'twist and tape' technology.
Yee-haw! 🤠
It gets fed the data from 'node-red' running on a Victron CerboGX via UDP packets over WiFi, updating as often as the data changes (approx 3 second intervals). The LED changes colour according to state, so 'All OK' is green, 'You're getting very close to/exceeding the inverter output limit, so if you don't want to pay for grid, don't turn anything else on' is red, then blue for 'dumping power into the hot water tank'.
It's by no means silent in operation. I originally made a single-servo version for just PV generation and coded it so that the meter movements were gradual (a kind of PID to get from one value to the next), but apparently it 'sounded like we have cockroaches' when it made it's ticky-scratchy transitions between values, so the big version just jumps between values with a 'zzziiiiiup!' sound.
It's actually quite reassuring to have an audible indication when the sun comes out for 5 seconds, or it starts charging at night.
I'd also put a little radar sensor in there, with the aim of having it detect when there was nobody around, so it could stop displaying to save power/noise. Unfortunately, that meant that every time you entered the room, all 6 needles would suddenly move at the same time, making you jump out of your skin and spill your horlicks, so we just leave it 'on' all the time now.
There's also a basic web UI, so you can see the same data on your phone or whatever, plus it's useful for troubleshooting:
I had fun and learned loads making it - and now it's become a family game to try to cook dinner without making the red light come on. 🙂
Libraries used are 'ESPUI' and 'servo', plus 'arduinoOTA'. Code, FreeCad file for the gearbox & stl file for the arrow-head needle are all in the attached zip.

Off-grid in Spain
Onze Finca posted a topic in Starting In Solar? Feel free to introduce yourself,
Hi,
I'd like to introduce myself, and my small setup.
I'm Bianco, a Dutch male, and my wife and I moved to Spain 2 years ago, where we live on a small piece of rural land, in Aragon. We are completely off-grid.
Therefore I Hired a friend two years ago to install a solar system. he and a friend installed a Voltronic Expert 24V 3Kw, with 6 320 Wp Solarpanels, and 2 Ultracell 316 Ah Gel Batteries, and I paid good money for it. After 1 year and a bit, every thing shut down at 2 in the morning, whilst the day before was a clear and sunny day. In the months after that, it started happening more and more. Well long story short, The Batteries were fried. After contacting the "friend" He basically told me he could do nothing: A bit like: Shit happens.
After studying I chose to do it myself. The panels were fine, so they are still there. I bought a new Inverter, another Voltronic Axpert, 5Kw, on 48 Volts And two Pylontechs US3000C
All connected, everything works fine. in the (hopefully near) future we'd like to add another Pylontech to the bank. Its enough for us. We have a TV, and we mostly watch during the day (if we do), and no dishwasher, washing machine or other heavy stuff, besides a Nespresso, but that is also only used during the day. The only thing that is a big consumer is the waterpump, but on a timer, controlled by Domoticz. During non-solar hours, it is off.
So I have a raspberry in the bedroom, wich is equipped with Domoticz, wich controls most of the lights, and a few other stuff. In the Batteryroom, there is another raspberry, wing contains Solarassistant, and monitors the Pylontechs via the Inverter.
I'm still looking for a way to connect the Pylontechs Directly to the raspberry, I read something about the console port, but can seem to find if you can connect it at the same time as the port to the Inverter.
So, Newbie in Solar, but I like learning about it, and helping.
If anybody knows something about connecting it to a raspberry, (or maybe my way of thinking is wrong) much obliged.
Greetings from a cold (+2), but Sunny Spain.

Newbie Question - Does hybrid mean you will never overload the inverter(if the grid is available)
Keill posted a topic in Inverters,
When I google this or ask installers, I'm getting mixed answers.
Some suggest that a hybrid inverter will get any extra load it needs, from the grid, if its overloaded.
Some suggest that even a hybrid inverter will fault/cut off if overloaded.
When I say overloaded, meaning if its a 5kw inverter and my load exceeds that.
Or is the truth somewhere in-between, certain makes/,models of inverters can and some can't?
Thanks for your time.-
