MORE PICS:

It’s 4am, so one pic show big black box on floor. That’s a 24v 200ah lifepo4 battery pack. I bought 4 and stack the 160lb beasties inside a server cabinet with the PJ inverter on a slider with extra cables.

Last pic, our house after the volcano blocked out the free stuff.

Best Regards!

Yet even more to add folks!

Finally got the touchscreen wrangled out. The lcd driver always was a problem getting to the factory menu. LVDS set to a 1, that’s all?? But hold down menu press power then hold down volume then don’t blink. Well then play around with Raspbian and get the darn thing to fill the whole 15.6 screen. Midnite solar has a new free application you log into and real nice so now I can quit that cloud service and have my rpi4 call me direct. I still need to figure out how to run an alignment on the digitizer screen if that’s possible on a raspberry pi.

Hi Solar that is a seriously high tech system you have. Makes my battery monitor look very low tech.
I just a Victron Bluetooth monitor that collects my information. I check it during the day to see how the batteries are going and that is it.
I do my best to keep the batteries above 80% charge. That is about it.
Then I don't run any high loads, a toaster and a few tools are the biggest things.
I guess you are monitoring your system from halfway around the world so it is a different story.
Hope it all gets sorted soon
Pete

Hey Pete!

This beast is still stateside. We’re hoping to make the permanent move in the next 12 months so I’ll have to take it apart and crate everything.

I’m debating whether to lift that coil up on rubber blocks like doc has done. Fortunately the inverter is on a slider to make it easier. At least now the air gets in the center. Now it need to glue the temp sensor to the coil with thermal epoxy.

Garden haul
Adios!

So it seems that no matter how well you crate these batteries and how much you explain they are one of the safest on the market all they hear is that word lithium and respond with now way in hell are they going in our shipping container.

I sold them recently on eBay for what I paid for them. I can only imagine how that Acura hatchback drove with 648lbs in the rear. I’ll just put the money on some new lfp’s from the factory. They are under $95 now for 200ah. Server cabinet will go and everything will go inside it when I build a suitable workshop downstairs. For now everything is on The  wall and floor of the guest bedroom. That went over well with the boss 🤔.

Seems odd doesn't it. As most things appear to be made in China these days. One wonders how the batteries get transported around the world in the first place. All the phones and computers with lithium batteries must be delivered by remote controlled submarines I guess.
Sounds like you are still having fun figuring out how to power the Phillipines on renewable energy.
Good luck
Pete

Hey Pete,

There is a trend now of American manufacturers making 12v lfp’s quote “Made in the USA” but everything inside is Chinese. A 200ah 12v averages $850when a pallet full of lfp’s brings the price down to around $75 each plus box plus bms. Again American greed pushing people to seek out Chinese sellers. 1 200ah lfp on ebay $225 and up. If you ship by sea a pallet cost $350 for 1 battery or 100 batteries.

I really want to expand my storage so we can have HVAC for all bedrooms at night. I have more roof to expand pv coverage in hopes of getting something on cloudy days. Still need that windmill too. Constant 10 knots and better during typhoon season especially this season. I really want to see how that delta resister setup you drew out and I built performs. The only time there isn’t much wind is the 5 months of summer of course that’s prime solar time.

In my ignorance I had not set my charge controllers to 58v but to 57v. I had the daughter change it and suddenly they went from charging at 30-32a  to 45a+. Hoping to see my shipment show up soon so we can get to 48v inverter and midnite controllers installed. Just upgrading to 48v should make a big difference. The Midnite controllers can be monitored on the web at the new cloud service and changes made as well.

Our new goal is make a permanent move early next year so fingers crossed.

Best Regards.
