I wonder if there is a different solution, maybe someone can mill a water cooling block for the inverter's components and then use an off-the-shelf water cooling kit for a PC.

Do any of you have experience with what fans are inside the SOL-I-AX-3VP? I want to order Noctua ones to replace the standard fans in the SOL-I-AX-3VP, but before I order it I want to know what size to get. Looks like an 80mm fan for the lager one, but the small one... I cannot figure out what size it is, doesn't feel standard?

I recently realized there is a considerable weight difference between the mecer batteries - ±14kg to 29kg So I opened them up, it seems Mecer is now shipping different variants some are prismatic cells and some are pouches. I am not sure if this is good or bad?

I have 1 left

I hope they give attention to adding support for the Victron MPPT charge controllers via VE Direct to USB in this new version, we practically handed the code to them on a silver platter.

The easiest by far will be to just do Victron MPPT -> VE Direct to USB -> Solar Assistant. The data is well documented SA must just prioritize this. Documentation for those interested; https://www.victronenergy.com/upload/documents/VE.Direct-Protocol-3.32.pdf

Weirdly, I can push to Solar Assistant's MQTT broker. But Solar Assistant is not proving a way to "fetch" the data and use it. However I can fetch it with Home Assistant from Solar Assistant. Odd, they must just enable the topics sub, then this can actually work. Victron MPPT and Shunt -> Bluetooth -> ESP32 -> MQTT -> Solar Assistant -> MQTT -> Home Assistant. This means the data is available for fetching via Solar Assistant if their devs enable it.

Solar Assistant doesn't allow the pushing of data. I am able to read everything from the Victron devices over Bluetooth, but cannot push to Solar Assistant, so will need to set up something like Home Assistant and then push data via MQTT from Solar Assistant and bridge data from the C app I wrote also to Home Assistant. Pitty.

This is my biggest fear in SA. We are probably the only house in our neighborhood with full solar. We stand out like a Christmas tree and I always wonder when Solar equipment becomes the next target for break ins.

Bullets are probably worth more than solar if the grid does collapse. If the doomsday preppers on Discovery Channel is anything to go by.

Baufeng, stocked up. Keeping GAS on rotate Have a 1kW 50L small geyser that I can run on a few solar panels and an AC microinverter and will then switch of the main geyser. The rest of the house is on batteries and solar, incl Fridges Have a water tank (2 x 5 000L) 500L petrol tank My biggest worry is sewerage, will need to invest in a porta potty or an incinerator toilet running on the solar. Grid collapse = no communication, no gas refill within 1 day, no fuel within 3 days, no running water, no sewerage within 4 days. Food shortage big issue, so stocked up on canned goods if you have chickens it helps. You have to be "off-grid" self-sufficient which most are not (including myself). Let's hope a grid collapse doesn't happen because it will not be fun, it will be a mass event that will put covid to shame.

I don't think so

My averaging function was the problem, apologies. Grid voltage between 240V to 244V feels high?
