Good job at taking a complex subject and explaining it in a straightforward manner. Wish I came across you before I built my system.

[@MikeKing-IC]

I appreciate the kind words Edward. Stuff like this isn't the most algorithm friendly so its good to know that people are getting something out of it.

[@edwardbroomfield2291]

@MikeKing-IC You're welcome, I believe in being honest, NOT MEAN. If you had committed an error that might have ended in a bad outcome, I would have pointed it out. But, I won't berate you. I think you're doing a great job.

[@MikeKing-IC]

Hope people find this helpful. I tried to write it as the primer video I needed back when I joined IC and started learning all this stuff.

hello,
I have two Pylontech batteries. I need to know how I can install live monitoring (WIFI).
The batteries are connected to a solar inverter.

Hi Charbel, thanks for the question. I believe you and Mike are already troubleshooting this via email, correct?

Check out an Australian company called Safiery. They have some excellent can bus dc dc converter tech for 48v high side to 12 or 24v low side bi directional power and charging for RV and mobile applications. Fully compatible with a Victron GX also 👍

Hey, thanks for putting me onto this; they are super cool. I’m going to do a deep dive on these and report back. - Mike

Palm head slap... Why do you keep calling it Lithium Fero phosphate? Fe on the periodic table of elements is iron. It's pronounced by EVERYONE else out there Lithium (Li) Iron (Fe) Phosphate (PO4 - ie a phosphorus surrounded by 4 Oxygen molecules).

Hey Jonathan. My goal here is to reduce some unfortunately common confusion. A hurdle we face is getting people to understand that LiFePO4 batteries are not the same as other Lithium Ion chemistries that have a widespread reputation for explosions and fires. Seeing as Lithium Iron sounds pretty close to Lithium Ion, I have found it helpful to just refer to them as Lithium Fero Phosphate, as most people don't get caught in the weeds on the proper periodic nomenclature.
