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.

Adios!

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

There is 2 gauges in 2 different locations... for convenience..

They are 500 amp 75mv shunts, so bugger all dissipation.

Hi Noneya!

Long time, looks great. I’ve been doing the Midnite Solar thing they finally have a cloud app it’s decent. Anyways, I see 2 shunts in series, is that to raise current handling capabilities or am I seeing it wrong.

i have used these devices for years and found some interesting things.... https://www.aliexpress.com/item/32866409420.html...

PRO:
very handy for state of charge, bi-directional current sensing..
seem pretty accurate...

CON:
the wireless signal is quite dismal, 10-15 meters advertised.. .bout that in real life..

so lets fix that, it uses the standard NRF24L01 modules... sweet order some palna+ versions , like this https://www.ebay.com.au/i/133381532534?chn=ps&norover=1&mkevt=1&mkrid=705-139619-5960-0&mkcid=2&itemid=133381532534&targetid=892931907096&device=c&mktype=pla&googleloc=9069084&poi=&campaignid=10101784961&mkgroupid=102311923620&rlsatarget=pla-892931907096&abcId=1145981&merchantid=7364522&gclid=EAIaIQobChMIvuvfp7yI6gIVwRErCh3ucQITEAQYAyABEgJZ0_D_BwE

matter of squizzing them in... sorry only took finished pics, but you get the idea..

first pic, installed in the "sender " unit, i have 2, one does wired in shed, other is inside house.
