so Currently i've Built 7x 1s30p Packs Li-Ion packs,
Some Details:
Nominal Voltage per 18650: 3.7v
Nominal Capacity per 18650: 2000mAh
Max Capacity per 18650: 2400mAh
Nominal Voltage Per ParallelCell:3.7V
Nominal Capacity Per ParallelCell 60Ah
Current cable runs are 0.2-0.5meters max per cable in the pack using 12AWG which is just within the limits on 24V@60A = 12AWG or10mm (73A max) according to a DC Cable Sizing tool at solar-wind.co.uk
I'm Building a Batrium Protected pack of 7s30p currently and when I add to the pack i'll add more once I have enough for a 14s30p pack of quality cells.
Currently the system is not in use yet. awaiting Batrium Biggest Starter kit Delivery this week as well as Solar Charge Controller, (Victron BlueSolar75/15)
and a Basic Reliable 2000W Off GridInverter, and i'm trying to make sure i got the Safety Part Correct.
I'll be Limiting Total Battery Discharge to 1C, so with my current calulations i think is either
1s30p = 60000mAh = 1C = 60A
7s30p = 420000mAh = 1C = 420A
which of the Above Values are correct?
haven't done a initial Discharge test yet as i've not got the BMS yet, but once that shows up this upcoming week, i'll need to be able to setup the Circuit Breakers between Everything correctly.
I'll be putting in a 15A Circuit Breaker between Battery and Solar Charge Controller.
I'll be putting a (2000W/120V = 16.66A)~15A Circuit Breaker between Battery and Inverter
I'll be putting asmall 120V@10A CircuitBreaker on the Inverter Output, for now.
I'll be putting a 60A Circuit breaker between Each Batteryin the pack as they might be pushing power Large amounts of power between them for balancing (Guessing here),and 1C is 60A per Parallel Pack
i'll be using a 30v @ 30A DC Power Supply with a 12v relay attached to the Batrium Expansion Board to feed the Solar Charge Controller until i get Solar Panels in Play
I'm trying to be as safe as possible as well as feed my curiosity, currently i don't have fuses on individual 18650's as i'm using the ******* 2.0 battery connector kit for now,
will move to using glass fuses on the negative side once i upgrade to 48V.
any thoughts or opinions on this Idea / buildout would be useful to improve or fix any mistakes.... thanks in advance for anyone that shares there knowledge...
Current Build includes:
BMS: Batrium Watchmon4 with Shunt and Expansion board
Battery Bank: 24v=7s30p = Current Capacity between 1554Wh & 1722Wh
Charge Controller: Victron 75V/15A
Inverter: 24VDC -->= 120VAC@16.66A =2000W
