Compare this to WatchPower.?
If you have an MPP-Solar or Growatt, SolarAssistant works for you.
This is on a pair of LV6548s
This is on a LV2424; (just one day of use)
Sorry, there is no "public site" to view the site.
No, SolarAssistant is not free. When you consider that WatchPower is...
Hydraulic Crimper
Cable Bender
Ratchet Cable Cutters
Cable Stripper
These are 4AWG to 4/0 AWG. If you are doing 250 MCM, you probably already have professional tools.
I prefer the 16T crimper instead of the 10T crimper because the 16T holds the dies in from both sides.
I just did a project with...
I have used several different BMS's, and only 1 balancer. Balance is by far the most critical part of maintaining a healthy pack.
"For the safety of your battery pack, balance and maintain the long life of cells, please make sure that your cells will use BMS!"
Remember a BMS monitors many...
It's basically just a matter of convenience and what part of the circuit you are about to mess with.
If you are up on the roof and forget to open the circuit, your only option is to pull apart an MC4 connector. If you had a cute little knob to rotate, then that is easier than messing with an...
"ITS IMPORTANT TO HAVE BALANCING IF YOU PLAN ON FULLY CHARGING AND FULLY DISCHARGING. JUST SEARCH ALIEXPRESS FOR "8S ACTIVE BALANCER". OR YOU CAN USE AN 8S BALANCE CHARGER WITH THE BALANCING FEATURE.
NOMINAL VOLTAGE IS 25.6V
FULLY CHARGED IS 29.2V
FULLY DISCHARGED IS 20V"

All in all when it is said and done, I figure the BYD's are equivalent to about 80-100ah new cells.
It's amazing what has happened to the price of new LiFePO4 cells this year. I have 64 new 280ah cells floating somewhere in the Pacific now. I'll be going from about 14 kWh to about 57 kWh, and...
New cells, for all practical sense, none.
Used cells, can drop in voltage considerably.
When you turn on a microwave, the surge will drop the volt reading, and as soon as the current levels, the voltage will rebound just slightly. After the microwave turns off, the voltage will return to pretty...
double axis tracker wins every time in every situation for most energy collected (but is the most expensive also, and the tradeoff for just more panels wins)
single-axis tracker (time of day tracker) is about 44% more energy than a fixed angle panel.
Some single-axis systems can more than...

. My "helper" helping.
I reused the wood from another project.
The helper approves it.
All the measurements are "screwed in place" to have a loose fit. I have about 1/8" play for side to side slop.
I only used the tape measure to get the centers of the cross...
Since these batteries are all new and hopefully manufactured at the same time, it's possible they all have the same internal resistance.
The newer ISDT can measure IR, but not the little BattGO. (https://www.amazon.com/s?k=isdt&ref=nb_sb_noss_1)
The risk you face is having one cell that has...
How many cells will be in the series?
When you parallel batteries, they passively equalize to each other by being connected to each other. This is not the case for the series batteries though.
I use a blue-tooth controlled BMS, it has all these functions:
Cell High Alarm
Cell Low Alarm
Cell...
Sorry about that, I read the message and totally missed the title part.
8 x 51.2v x 280 ah = 114,688 or 114 kWh.
You will basically have 8 batteries of 14 kWh each. (I have 4 in the same capacity ordered)
I plan to make 4 sets of 16, each with their own Chargery BMS.
I am putting all 4 sets...
Out of the trailer, on the dock.
Headed out to the beast of a truck with it's toy trailer.
Off the trailer, and laid out on the ground.

Do you have any idea what the start amps are to get the pump going?
I found this soft starter. As far as I can tell, it is the only plug and play option available.

If you are going to have more than one ANT-BMS in your setups.
Do this 1st!
Change the Blue-Tooth MAC Address (3rd page down at least). Just anything else will work fine. As soon as you get the next BMS turned on, you will be able to connect to it. The button on the main screen that shows...
