Here is my just completed solar setup.
Since LFP battery does not like sub-zero temperature, I added a lead acid battery warmer and it keeps the battery at 20C, considering add some thermo control relay to control that around 10C then cut-off

I currently have the Rockpals 500 (paid about $420, 4 days left for the return window)
My only requirement is to power my 12v fridge + phone/tablet
the max solar input I can achieve is about 85W
(they claim it has MPPT in it but I dont believe because I can get 92W with my Renogy 40A MPPT...
I am buying three of the BYD 24V battery modules, picking them up next week from batteryhookup store.
According to the specs, it works with standard 24V systems (I have a MPP Solar 24V Hybrid Charger Inverter so sounds perfect to me)
NOMINAL VOLTAGE IS 25.6V
FULLY CHARGED IS 29.2V
FULLY...
Right now I am trying to test the capacity of the DELTA 1300 via DC
Fully charged for 12 hours (ensure its really full) and connect to my DC compressor fridge (about 40-60W)
after 20 hours, the panel is showing 47% and the meter is showing usage of 507.0Wh
so far, I think the total capacity...
My pack currently has about 0.05V ~ 0.079V different between highest and lowest voltage of the cell
the BMS is only able to balance it with 200mA current...
What should I do?
Active Balancer? Or just Charge to full and leave for a month to wait for it get balanced?
I currently have the following stuff
Clamp Meter, used by DavidPoz and I think I would take it as the point of truth???

This evening all my ups are triggered due to the mpp solar has been shut itself off strangely.
Checking the BMS of my BYD Pack and found low voltage cut off is activated, wonder why
Recently we are expeiencing rains and snows, so the battery is not getting charged via solar.
and I did set...
very unfortunately I have to move out of the region, need to selling all my solar stuff
I have 6 pc of 230W Poly 60 Cell Panels

Hey guys
I am trying to figure out the way to prevent spark and damage to inverter/charger when connecting to the battery.
I do know Will showed using a wirewound resistor to pre-charge the capacitor so that no spark and damage will happen.
however, I have very difficult time to find a 25ohm...
I am looking for BMS for my other 3 BYD battery packs
so far I am happy with the Ant BMS as it has low temp cut off and highly configurable via Bluetooth with their App
Bowsering the forum and I notice other two popular BMS, Tiny BMS and Chargery BMS
Chargery BMS has software upgrade ability...
I just hook the wifi box up with my LV2424 today.
No 12V input needed for the wifi box (YAY, and the manual says it requires AC adapter but in fact you dont need it)
Default it sends data to power-datacenter.com and honestly, it does not look secure or safe (no https)
so...
Is it possible...
I got the LV2424 from usa-mpp-solar 2 months ago and I am extremely happy with my purchase.
I am following the guide and get everything working
But from yesterday... the USB Port of the inverter is not working.
I tried with 3 different computers and same for all of them.
Trying to contact...
