Most of the BMS's seems to have low number of Temperature sensors (e.g. JK BMS 1 to 3 temp seonsors).
Since the cell count is usually high 8s-16s, if a cell that is NOT in touch with the temp. sensor heats up, BMS will NOT detect it and could lead to a catastrophic failure.
Is there anyone who...
Most of the existing videos/articles on selecting MPPT controller does NOT consider Maximum Charge current of the battery.
I have few question regarding this,
Say a 24v/50AH LifePo4 battery used with a 1100W(total power) solar panels.
Assuming safe charge current of the battery is 25A (i.e...
Sorry, I know this topic is discussed in different threads and it seems to be a matter of opinion (mostly for high capacity setups)
I saw below OffGrid Garage video, As I understood, for a high capacity stationary setup(since cycle count is low), compression might NOT be useful.
BUT if we...
Some MPPT Solar charge controllers have the capability of supporting over paneling AND limiting the maximum charge current for the battery below SCC's max limit.
e.g. SRNE (or BougeRV), EPEVER, eSmart
What I mean by over paneling here is utilizing a lower wattage by using a higher wattage PV...
I saw in several places that, MakeskyBlue, PowMR or EASUN Solar Charge Controllers are all re-brands of SRNE (or Voltronic) AND they are able to use SRNE Software applications with MakeskyBlue, PowMR or EASUN SCCs.
If this is true, I am guessing one should be able to communicate (read/change...
Both SRNE and BougeRV products(e.g. MPPT controllers) looks very similar.
Are they the same company and same line of products differing only in name ?
If they are the same, anyone know why they use 2 different names ?
I have seen positive reviews of both products.
Anyone using SRNE MPPT...
Hi all, this is a kind request for a improved guide on building LifePo4 DIY battery packs.
Existing guide https://www.mobile-solarpower.com/design-your-own-12v-lifepo4-system.html does not mention details like below
- Compressing cells
- Direction to place cells
- Best cell arrangements (for...
Hi, I have a single Panel with below specs,
Pmax=550W Vmp=31.6v Imp=17.4A Voc=37.9v Isc=18.52A
Used for about 1 year now.(with a 12v Gel battery. Planning on switching to a Lithium battery as Gel battery capacity has dropped)
I tried to find another panel with same specs but could...
I currently use Deep-Cycle lead acid battery(12v-100AH) with my small Off-grid solar system, but since it's(Battery) capacity has dropped significantly after using only for a 1 year, thinking of switching to a LifePo4 pack (since I don't like to buy a new battery each year).
But the problem is I...
