All,
I am stumped, questions below.
The attached image roughly describes the system. Here are text details:
PV: 4x 100w Rich Solar 2s2p
SCC: Victron 100/30
Breaker: Blue Sea 7182, 40a
Busses: 300a 4-stud from Current Connected
Cut-off Switches: Blue Sea 6006
Batteries: 4x SOK 100ah
Shunt: Victron Smartshunt, with bluetooth dongle
Charger: Victron IP22 12v, 30a
Inverter: Renogy 2000w pure sine wave
Auxiliary AC panel: Reliance #104B1, 4 circuits
Cable Sizes: PV to cut-off switch to SCC = 10 awg
Cable Sizes: SCC to breaker to bus = 6 awg
Cable Sizes: Battery bank connections = 2/0 awg (9” each)
Cable Sizes: Battery to 200 amp fuse to bus = 2/0 awg
Cable Sizes: Bus to inverter = 4 awg (Renogy supplied)
Key:
Red = positive
Blue = Negative
Green = ground ???
* System is not tied into grid
** Object of the system is to voluntarily (manually) supplement ‘house’ AC power as a 12v system to save costs, for back-up and proof of concept
*** BUT I would like the potential to upgrade to 24v system if this experiment works out
QUESTIONS:
Should cable from bus to Renogy inverter be larger than the 4 awg that Renogy supplied (my sense is yes, make it 2/0 but perhaps Renogy knows what they are doing)?
Does inverter need to be grounded if it is being connected to house AC with Reliance transfer panel?
Is it OK to solder the terminals on the 2/0 awg cabling (my current crimper only works to 1/0)?
Do I need a battery balancer for the four 100a/h LiFePo batteries?
If the concept works for me and I wish to upgrade to a 24v system, which components must be changed? Inverter, obviously, and batteries rewired to 24v configuration, and additional PV panels ... anything else?
Thank you for being patient as I walk through this,
SFR
