My plan is to get the Batrium Watchmon 4 with 500 amp shuntmod to handle a 14s160P (18650 battery~20.5 Kwh) with a 2.1 Kw solar array.
What I am looking for help with is the other particulars. That is:
What solar charge controller? I am looking at the Victron Energy SmartSolar MPPT MC4 150V 60...
They do not list an amperage, but I figure they are 350 watt panels with a VOC of 40.73 V so amperage of 8.6 amps. The 15 amps would be for each two panels hooked in series. So a total of 45 amps for the 3p.
They will be these panels.
Since I have all same cells (year, chemistry, everything). I will make up an extra pack. What complicates my situation is, my packs have a "handiness" to them. That is, every other pack had buss bar that exits the packs differently (one in the front the other in the back). But I...
I am just curious how many folks have circuit breakers on there solar panels.
I am going to be getting 6 350 watt VOC 40.73 v (running two in series for 48 V system 3 parallel), so I am figuring a 10-15 amp breaker on each of the parallels.
If you are using them, which ones would you recommend?
I have finally processed and cataloged my cells for my Powerwall build (14S160P). It was my understanding that many folks make an extra pack, so they have one to swap in if they need to fix something in one of the packs. Is this common or unusual?
The 18650s that I have collected came out of medical packs that were sealed inside a case of an injected rubbery substance.
In digging them out, some, heck most of the cells have some amount of the rubber stuff in the vent holes.
This is an extreme example, most have a few of the vents open...
Ahh, no good for LiFePO4, I think that is a deal breaker, as I plan to go that route down the road, and if I am dropping a grand I want to make it capable. Ahh, and I can set temp, so if I have some problems I can adjust.
Thanks Wolf and OffGridinTheCity, that is what I needed to know.
As I prepare to get my battery and new solar set-up together, I run through scenarios in my head.
As I understand it, the biggest difference between the Batrium Watchmon 4 with longmods and the Watchmon 5 without longmons is, the Watchmon 4 allows for 28 Ah a day of balancing, while the...
