Libre Solar

Aiming to provide energy access for everyone using affordable renewable energy solutions based on open source hardware.

The current state of the EU's Cyber Resilience Act (CRA) will have severe and negative consequences for open source communities. Help us #FixTheCRA by making your voice heard. Learn more at https://t.co/m68mLKlRxo @LF_Europe @ep_industry

ThingSet + #ZephyrRTOS: Transport-Agnostic Device Connectivity Within 10 Minutes. Need to see it to believe it? Martin Jäger w/ @LibreSolar will present a live demo at #ZephyrDevSummit. Register to attend virtually and add this to your schedule: https://t.co/5wgYlbMvzm @ZephyrIoT

[EnAccess Foundation @EnAccessFdn]

The #opensource #BMS, created by @LibreSolar and funded by @EnAccessFdn can save you a significant amount of money. How much? Martin Jäger, Lead Developer, explains it all here. Get your hands on all the Open Source tools you need to get started here -> https://t.co/azuGwvhpBw

[Libre Solar @LibreSolar]

Prototypes of our new BMS C1 funded by @EnAccessFdn are currently being assembled at @fabulousstpauli. Really excited to power them up later today.

[EnAccess Foundation @EnAccessFdn]

Can building your own #renewableenergy system really be as easy as assembling IKEA furniture? Yes! It’s all about open educational resources & taking an #opensource hardware approach.

@dotunebiekuraju @kicad_pcb Looks great! We are also developing MPPT charge controllers (as Open Source Hardware) with KiCad, but most designs are still with v5. Just now switching to v6 for our next gen BMS. Check out https://t.co/AiuRvVEJ6v.

We are applying for funding from @EnAccessFdn to develop a next gen #opensource and IoT-enabled 48V Battery Management System running @ZephyrIoT. Suitable for 2nd life, productive use and micro-grid applications! Leave your feedback here to make it happen: https://t.co/hZHm2VRuB4

[Libre Solar @LibreSolar]

On June 9 we will talk about using @ZephyrIoT for digitally controlled Solar Power Converters at #ZephyrDevSummit. Register now and get in contact with the amazing Zephyr community: https://t.co/v5WIUq8Yw0

The deadline to register for the #ZephyrDevSummit is tomorrow! Check out Day 2 sessions from @AVSystemCom, Circuit Dojo (@jaredwolff)@intel @IntelSoftware @LaasCNRS @LegrandNA @LibreSolar @LinaroOrg @lpnplant @muni_cz @percepio & Teslabs Engineering: https://t.co/dI53Sn30cJ #RTOS

[Zephyr Project @ZephyrIoT]

Last week at the @LFE_Foundation Spring Summit, @LibreSolar presented the Open DC Grid Project w/ @jlgula1953 & talked about using @ZephyrIoT for power electronics. If you missed it - check out the slides: https://t.co/l6jnP67pCY #LFEnergySummit #ZephyrRTOS #opensource #RTOS

[Libre Solar @LibreSolar]

@JordoSilverman Yes, it was recorded. Will be published on YouTube soon, as far as I understood.

[Libre Solar @LibreSolar]

Q&A session in the middle of the night :)
We talked about how #opensource standards and hardware can help to accelerate access to clean energy in off-grid areas at #LFEnergySummit.

[LF Energy @LFE_Foundation]

The Open DC Grid project is an initiative to define an architecture to permit devices to exchange power using LVDC and document it in a standard that can be freely accessed and used by anyone.

Thank you @jlgula1953 & Martin Jäger!

@_kate_stewart @ZephyrIoT We could only scratch the surface in this talk, so we are planning to dive deeper into Power Electronics Applications on upcoming Zephyr Developer Summit.

[Libre Solar @LibreSolar]

We will present the Open DC Grid Project (https://t.co/Q6lUJBfz8n) together with @jlgula1953 and talk about using @ZephyrIoT for power electronics at @LFE_Foundation Spring Summit. Hope to see you there! https://t.co/t1zD3UY4Cm

[Libre Solar @LibreSolar]

Next gen 20A MPPT charge controllers just arrived and ready for testing. As usual, boards developed with @kicad_pcb and fully #opensource: https://t.co/clgBbnJ4Dr
