This is a long one, but, chapters below!
In this video, we use a Victron Cerbo GX to configure the Quattro using VE.Bus, not VE.Direct. We go over the OverkillSolarBMS configuration, and get everything connected and turned on for the first time! The batteries feed a 120v AC load, and we charge the batteries from the Quattro!
The sections covering the Cerbo GX and BMS (via the Xiaoxiang app) configurations are very much "Learn with me" format. You may wish to skip those sections if you just want to see the system working.
The last section of the video is a build of a panel to mount the GX Touch 50 display. I forgot to do my outro... Woops. :)
If you found this video from Victron's website, then I am absolutely certain you will love the videos "Off-Grid Garage" makes. Andy's videos go into a technical depth and does experimentation that is extremely insightful on energy generation and storage. His videos are what got me started on building this power system.

![Lightning & Sailboats, Beyond TE-4 - Ep. 124
For over four months, I have been working on a new lightning protection system. I am still learning, but with spring arriving, its time to get back to boat work.
In this video, I talk about what Ive been learning, and give hints at what will be coming as the lightning protection system and the associated paper takes shape.

![Ep. 88 - Damaged Battery Test Results
Edit: Sorry about the audio. I accidentally turned the mic volume down, and tried to boost it in post. The audio seemed OK before I uploaded it. It seems youtube somehow compresses or somehow edit s the audio and makes it break up more.
In this video, we recharge and then discharge the battery with the cell that fell to 2.0v. The test results were less than optimistic, but not in a way I expected.

![Ep. 104 - A New Project, Two Project Updates
When is an outboard more than just an outboard? When its electric and a get-home motor!
This video is a peak behind the scenes of the kind of work that happens between builds. I talk about the new outboard project, and how it will also be the emergency way of getting Mermaids Rest to safety, should she ever suffer a loss of power. I also give you an update on the new battery box project, and a wee look at the prototype boards Ill be using to debug the helm controls.
